iPhone 3G Coverage Complaint Maps - New!

With all of the excitement of the iPhone and 3G there are issues with the technology that may require further investment by carriers in infrastructure to provide seamless coverage. 3G technology operates at higher radio frequencies than earliest 2G systems and does not penetrate inside buildings as effectively. Voice quality may suffer and data rates are often much reduced.

DeadCellZones.com has launched a coverage complaint map that is optimized on the iPhone to when you are away from your computer. https://iphone.deadcellzones.com Type in your zip code, city and address to search for other complaints in the area. Add your comments on the coverage problem whether you are indoors and the type of device you are using to help carriers better understand how to solve the problems in the neighborhood.

Cutting Costs By Cutting The Cord

It is no surprise that consumers are becoming increasingly dependant on their mobile phones. Whether they’re checking email, downloading videos, or making a call, users rely on these devices to stay connected. CTIA Wireless Association estimates that there are 267 million cellular subscribers within the U.S., giving cellular phones more than an 85 percent market penetration.

As the cellular market grows, traditional landlines are going the way of the dinosaurs. One reason is the tightening U.S. economy. As budgets tighten, consumers are looking for ways to cut their spending and are beginning to see their landlines as a quick way to cut costs. According to the Nielsen Company, more than 20 million U.S. telephone households (17 percent) rely solely on a mobile phone for their home telecommunications.

Despite the growing dependence on cellular phones, infrastructure issues still exist and cellular reception woes plague users across the country. Surprisingly, reception problems are no longer an issue reserved for sparsely-populated, wide-open areas of the country. Dropped calls and reception issues exist from the streets of New York to the deserts of Arizona.

As consumers look to cut the cord, they need to be able to trust that their cellular devices will keep them connected. This includes selecting the right tools that enable them to make or maintain a strong data connection.

There are several tools for consumers to consider, including cellular signal amplifiers and femtocells. Femtocell users, however, should consider the significant technology limitations of this technology including user subscription fees, single-carrier access, and the necessity for a high-speed Internet connection (See the contributed post on femtocells).

Cellular amplifiers (such as those manufactured by Wilson Electronics) do not require a subscriber fee or an Internet connection, they fully support multiple carriers on multi-frequency bands, and are available in both mobile and in-building configurations. These devices enable users to reduce dropped calls and improve performance for mobile phones and laptop data cards, allowing users to trust that their cellular device will always keep them within reach.

AT&T Testing In-Home Cell Phone Antennas

AT&T is following in Sprint's footsteps by experimenting with in-home mini cell phone tower what they have branded the Microcell, otherwise known as femtocells. Sprint has been selling its own under the Airave brand. Femtocells are made to boost the cell phone signal via your high-speed Internet connection; think of it as your very own cell tower.

This is great for consumers who are unable to boost a weak signal with repeaters and have zero bars of coverage outside their home. However, one possible limitation as these new personalized cell phone towers roll out is the possibility for interference with your neighbor who might have good coverage already. Your neighbor might not be happy with you if you start interfering with his coverage network.

I think it is going to be critical for carriers to do their research on their own perceived coverage as well as their competitors in certain areas before they start offering these products to the masses. We have plenty of cell phone coverage complaints in our database for carriers to analyze when making decisions about regions to target. Lets just hope they all start paying attention to what their customer is saying.

College Campus Cell Phone Coverage

How is your cell phone coverage on campus? We are are beginning an aggressive marketing campaign to help identify coverage problems at colleges and universities throughout the U.S. Our goal is to identify campuses with particularly bad coverage problems and regularly highlight these campuses on our maps. Indoor and outdoor coverage problems should be identified on our maps if you cannot send or receive phone calls. Just put a pin in our map if you have an annoying location that you would like to see improved. The carriers are watching so your efforts will not go unnoticed. Please email your friends on campus and put a pin in our map!

Below is a map of USC in downtown Los Angeles that appears to be pretty good minus the one Verizon complaint.

Coverage Map For Retailers

DeadCellZones.com has launched a new full screen version of our coverage maps after receiving number of requests from cell phone retailers around the U.S. who are going to start using our maps in stores. Our maps a designed to "help consumers help carriers" prioritize coverage upgrades by communicating problem areas more effectively.  Now that our maps have a critical mass of data points (27,000+ locations) and growing consumers are finding the information valuable to share and make better decisions about which carrier to choose. See the regional map below of Palos Verdes, California mobile phone retailers use in Southern California.  Companies like Root Wireless crowdsources signal strength and allows consumers to kind of view.

We are actively in the process of building relationships with a number of independent wireless retailers throughout the U.S. and this will be the focus of our efforts at the CES show in January and in throughout 2009. Independent retailers have started to recognize the need for personalized wireless coverage maps for neighborhoods and offices as many users are 100% dependent on their cell phone exclusively. Often improving coverage is requires purchasing a repeater or femtocell in your home or office to improve the coverage and retailers are starting to play a bigger role in fixing coverage gaps for consumers.See Our Full Screen Map

See Us At CTIA Wireles 2009

We are scheduling meetings for the CTIA Wireless show in Las Vegas on April 1-3, 2009. We are not planning on having a booth but and will reserving meeting rooms as needed. Please contact us if you are interested in meeting with us about the following:

1) Map licensing
2) Cell tower management companies
3) Carrier partnerships
4) Femtocell marketing and advertising

Licensing Dead Cell Zones Maps

If you are in the business of improving cell phone coverage for carriers, consumers or business I would like to suggest licensing our maps to better target your customers. Carriers have done a fairly good job at mapping coverage based on drive data. All of the major carriers have spent hundreds of millions of dollars driving around the U.S. measuring coverage. That is great if you are always in your car and talk on your phone outdoors but a growing number of consumers (now >20%) are dropping their land lines and need coverage in their homes and offices.

Today's coverage maps provided by the big carriers provide approximate coverage if you are outdoors but no value if you are indoors. Depending on the construction material and windows in your house your coverage may vary greatly from that of your neighbor. Our coverage complaint maps are designed to be very detailed and users can submit coverage problems in their home or at their office. This data can be very valuable if you are in the cell phone tower management business like American Tower, Crown Castle and SBA Communications. Another similar business like Femtocell providers will eventually be demanding this information as well but this market is still in its infancy.

Our data is also of interest to real estate professionals. Before you buy or lease a house you might want to check for coverage complaints submitted in the neighborhood. Real estate web sites like Zillow and Trulia might soon be licensing our data to help provide more information to shoppers.

20% Adults Work From Home and 20% of Homes Do Not Have a Landline

The traditional workplace environment is rapidly changing as today’s business professionals become more mobile. Tied to a desk, working the nine to five is no longer the norm as more professionals are on the go, in the field or at customer sites, if not working from home offices.

Among the factors changing the traditional workplace environment:
• Economic and environmental concerns are encouraging companies and business professionals to tele-work. In a recent report, Forrester Research states 21 percent of U.S. adults currently work from their home
• The booming opportunity for global business is here. Over 80 percent of business travel organizers polled at the 2008 Business Travel Show in Dubai believe business travel is set to increase exponentially over the next 12 months.

In these non-traditional work environments, communication tools are also changing. An example of this change is the replacement of landline telephones with cell phones. Research firm Harris Interactive found that one in five U.S. adults do not have landline phone service in their home, with most relying instead on cell phones for communication. In addition, for data communication, the mobility of data card-equipped laptops offers business professionals the flexibility that a cable-tethered computer does not.

Greater mobility is an asset for business professionals; however, current technology is frequently unreliable, and spotty cellular reception often interferes with smooth business communication, leaving professionals without access to e-mail, the Internet or the ability to place important calls. Dropped calls or limited access to a strong cellular signal can potentially ruin a sale, limit productivity and reduce efficiency.

With these challenges, it is important that business professionals adopt the right tools to help maintain seamless professional cellular signal communication in non-traditional work environments.

There are several tools for business professionals to consider, including cellular signal amplifiers and femtocells. Femtocell users, however, should assess the significant technology limitations including user subscription fees, single-carrier access, the necessity for a high-speed Internet connection and the fact that use of femtocells is restricted to homes, offices and other in-building environments. See our blog post on femtocells.

Cellular signal amplifiers (such as those manufactured by Wilson Electronics) do not require a subscriber fee or an Internet connection, fully support multiple carriers on multi-frequency bands, and are available in both mobile and in-building configurations.

As today’s work environments continue to evolve, business professionals require the ability to have flexibility and innovation to keep pace. This includes selecting the right tools enabling them to get the job done. Cellular signal amplifiers are one such tool that can help today’s mobile professionals stay connected and maintain the poise and professionalism the business world demands.

Femtocell Companies Funded In 2008

The femtocell market has seen a few large investments in recent months, showing that the industry has strong market potential and there are lots of home and commercial dead zones to fix. Prominent players (e.g. Airvana, Ticker: AIRV IPO in July of 2007 for $60M, picoChip $27M, Ubiquisys ($25M) were funded in 2007, the emerging industry appears to be reasonably well capitalized for the turbulent times ahead and growth. Investors are hoping for more commercial deployments of femtocells during the next 12 months, setting the stage for mass market deployments during 2010. Here are a few companies that were successful at raising money in 2008.

October 2008 - Kineto Wireless $15.5M, which includes substantial amounts from NEC and Motorola.

September 2008 - Percello raised $12M to fund development of their femtocell chipset, bringing to $18M the total investment raised.

August 2008 - RadioFrame raised $26M to expand their picocell and femtocell range, bringing investment up to $100M since 2001.

May 2008 - Qualcomm and other venture capitalists invested an undisclosed amount in ip.access

January 2008 - Airwalk received $10M

Updated list from 3G in Home Blog
  • Airvana: IPO
  • AirWalk: $10 m
  • ip.access: strategic investment from ADC, Cisco, Qualcomm
  • Kineto: $15.5 million round including Motorola & strategic investment from NEC
  • Percello: $12 million
  • picoChip: strategic investment from Samsung
  • RadioFrame: $28 million
  • Tatara: $6.5 million
  • Vanu: $32 million
  • Ubiquisys: $25 million round including VC money and Google as a strategic investor; further strategic investment from T-Ventures.
DeadCellZones.com sits in a unique position based on our brand recognition and utility to educate the market about femtocell technology as control of in-building-coverage is suddenly in the hands of consumers and not carriers any longer. The masses are still not very familiar with the technology but its starting to trickle down to early adopters and we hope to provide a source of information for these companies where the coverage pain exists.

Verizon Fios Gift Card Scam

I apologize in advance for being a bit little off topic but I just had to rant to demonstrate the arrogance of the telecommunications giant Verizon to push consumers around and lie. Apparently business practices in Verizon's land line business is quite similar to their Verizon Wireless practices. Bait and switch coverage!

John McCain Installs Cell Phone Tower At His Ranch

Here is some evidence that you must have influence and power to get carriers to set up cell phone coverage on your private ranch or remote area.

This week there's been a bit of a brouhaha over whether or not Verizon Wireless gave Arizona senator and presidential candidate John McCain special treatment by building a cell tower near his Arizona home. The Washington Post says it did, Verizon Wireless says it didn't.
The Washington Post suggested in a story that Cindy McCain, Sen. McCain's wife, requested that Verizon Wireless build a cell tower near their home in Arizona to improve coverage. Since there is now a tower there (even if temporary), on the surface it looks like Verizon responded to McCain's request. But not so fast.

Verizon Wireless, responding to the story, issued the following statement:

The Washington Post story regarding Verizon providing a cell tower to the McCain Ranch is wrong. Verizon received a request from Mrs. McCain, but declined. Subsequent to that, the Secret Service made a legitimate request for a temporary tower for its work and Verizon complied, as is required by our contract with the agency. The Secret Service request, made on May 28, specifically said it needed the service urgently and requested that Verizon "explore every possible means of providing an alternative cellular or data communications source in the referenced area and provide any short-term implementation of any type as a solution in the interim."

Repeaters for Coverage and Femtocells for Speed and Capacity

There are several technical solutions for dead zone coverage in your home, ranging from:
  • Chasing your network provider to install extra cell towers near your home, improving signal strength throughout
  • Switching network providers to one with better coverage in your area (always worth checking before taking out a new contract)
  • Installing a repeater to boost the signal between your cellphone and the cell tower
  • Using an operator's dual-mode WiFi/cellphone UMA service, such as T-Mobile's hotspot@home
  • Using a dual-mode WiFi/cellphone, but making calls using a separate internet VoIP program such as Fring or Truphone
  • Using a femtocell, such as Sprint's Airave

Broad Tradeoffs between signal repeaters and femtocells

  • Repeaters are a one-off purchase and can be self-installed.
  • WiFi based solutions may not require any installation (if you already have WiFi at home), but require a WiFi or UMA capable cellphone.
  • Femtocells are self-installed by connecting to your broadband at home - they become part of the wireless operators network and attract a monthly fee.
In particular, there's quite a lot of debate between signal boosters and femtocells.

Signal Boosters are great for poor voice coverage in sparsely populated areas

Fans of signal boosters argue that for a one-off fee, the problem of poor coverage is solved. It benefits all users - there's no additional charge or fees for boosting calls, so owners are happy for anyone to use them. In some cases, they can also boost signals for more than one network (some types of booster are dual band and can handle frequencies from different operators).

WiFi needs a dual-mode cellular/WiFi handset

WiFi/UMA operators highlight that there is usually nothing to be done to install their system in your home - many homes already have WiFi. The issue is buying and configuring the cellphone, and sometimes configuring any security protection on your WiFi network to allow access. There is a small, but growing, range of handsets available to be used in this way. Some models have had VoIP withdrawn recently, with manufacturers citing lack of demand for this feature. Indeed, most people are happy enough to use the standard phone in the normal way and just expect it to work.

Femtocells solve poor coverage but bring increased capacity and data performance too

Femtocell advocates would claim that this is what their solutions offer. Femtocells are fully functional cell-towers, but miniaturised into a unit of similar size to a WiFi access point. They connect to the cellular operator's network using your broadband internet link (cable or DSL). They are compatible with existing phones, although you can restrict whether your femtocell is available for anyone to use for calls, or just accessible from nominated cellphones. When entering your home, the cellphone switches to using your femtocell and calls are sent and received in the normal way - it just uses your own broadband rather than the external celltower. The downside is that your cellular network operator will typically want a monthly fee for you to continue using it, although this can be wrapped up in your overall bill.


In sparsely populated areas, repeaters may well be a good and appropriate solution. I liken them to having a megaphone installed on your rooftop, allowing you to use your normal voice to project further.

But the radio planning teams within network operators find that these devices can cause untold problems in some situations. Imagine a densely populated area where many poeple were shouting through a megaphone - it would affect those who weren't using one. As with any shared resource, those who shout loudest get served first, whilst the ordinary guy gets poorer service. This can make it diffiicult for the radio planning teams to decide the best place to install new cell towers, and how to tune the network by varying power levels and frequency allocations etc.

Another reason to use femtocells is to offset the growing usage of mobile broadband data services. Each femtocell has the capacity today to handle 10 Mbit/s or more, and future versions will have the capability of 100 Mbit/s or more. This is replicated throughout every femtocell installation in the country - if millions of femtocells are deployed, then the total capacity is enormous. Outdoor cellsites have a similar capacity - today's 3G cellsites may have 3 or 6 sectors and therefore somewhere in the region of up to 50Mbit/s maximum; 4G cellsites may be ten times that. But each cellsite is serving something like 1000 subscribers (this includes those with phones switched off, not on a call etc), so the actual capacity per user is much reduced. Femtocells dramatically increase the data carrying capacity of the network, and by offloading traffic that would otherwise be carried on the outdoor network, free up capacity and improve quality for those who need to use the service away from home.

Finally, for data services, the short distance between the laptop and the femtocell will dramatically improve the radio connection and therefore quality and throughput it can offer. By using a femtocell, laptop and mobile data users will get a much better, faster experience which will use less battery power.

Summary: Boosters vs Femtocells

To summarise, in some situations signal boosters are good to solve poor coverage issues in remote areas for voice service only. In urban environments or where 3G data services are required, femtocells or WiFi solutions are needed to achieve best results.

Femtocells Do Have Limitations

Some people in the mobile market are touting femtocell offerings like Sprint’s Airave or T-Mobile’s @home as the newest technology that will revolutionize the mobile market, allowing people to drop their land lines and solely use mobile devices moving forward. While they do offer some advantages, femtocells have far from proven themselves and have some significant issues for users to consider:

• Femtocells are effective only in the home or building where they are installed, and they lock users into a monthly broadband subscription fee. They are not able to boost cellular coverage in a mobile environment.
• Signal improvement is generally limited to a set number of phones previously programmed into the femtocell during set-up.
• Femtocells, like the Airave and @home, are carrier specific and won’t boost signals for multiple individuals with differing carrier subscriptions.
• Perhaps most notably, femtocells require a high-speed Internet connection, something currently unavailable in many areas of the U.S.

Unlike femtocells, cellular amplifiers are not tied to a broadband connection. This eliminates additional monthly fees and provides help to those without access to broadband service. Amplifiers from Wilson Electronics boost all incoming and outgoing cellular signals within their frequency range, greatly reducing dead zones and dropped calls. It is important to note that Wilson cellular signal amplifiers in particular are type-accepted by the FCC and are available in a wide variety of wireless and direct-connection models.

The benefits of an enhanced cellular signal amplifier have encouraged many consumers to look into any and all technology that promises extended and enhanced signal reach. When evaluating technology, especially femotcells, pay attention to the details and limitations it may have. If looking for a mobile, accessible cell signal booster, you might want to consider a cellular signal amplifier instead.

Don't Be Afraid of Verizon Dead Zones?

Hey Verizon Wireless ... there are still hundreds of thousands of people still afraid of Dead Zones. Just look at the complaints on our map. I find it quite comical that wireless carriers are still patronizing our intelligence to think that they have perfected network coverage inside of buildings. The Verizon Wireless commercials Don't Be Afraid of Dead Zones actually are actually pretty scary. I was 7 years old when I first saw "The Shinning" a Jack Nicholson hit in 1980. I still have scars from seeing that movie at such a young age. I think it remains one of the scariest movies I have ever seen. It is ironic that Dead Zones remain one of the most annoying things thousands of mobile phone users still have to deal. It is amazing how we continue to thousands of organic visitors and hundreds of complaints on our map everyday.


3G Network Dead Zones

Verizon Wireless has a new commercial that launched at the Super Bowl patronizing its' customers and trying to brain wash others that they have the perfect solution. When it comes to 3G, I think Verizon, AT&T, Sprint and T-Mobile are about the same when it comes to coverage. 3G is a lot of hype but the last mile of coverage to the home and office is going to be solved by other solutions than existing networks.
Like many other consumers in the U.S., I waited patiently to see just how great the new 3G iPhone would be. The hype around 3G network benefits prompted many consumers to wonder if mobile computing’s true potential would now be realized. However, when I looked at AT&T’s 3G network coverage map, I was astounded. There are some significant holes in coverage to say the least. Several consumers have also reported that, despite claimed 3G coverage by AT&T, the only available network coverage was EDGE, which isn’t comparable in network speed or performance.

Disappointment comes with the hype that 3G was a new, better cellular network. Consumers thought they were getting a better product, with better, faster coverage, but current 3G network coverage is spotty at best.

3G network woes are unfortunate, but consumers can take advantage of 3G iPhone features even with less-than-perfect network coverage. Many consumers don't know that they can make the most of a 3G phone and network by boosting the cellular signal with a cell signal amplifier. Amplifiers are a great solution to making the most of a new gadget by providing increased coverage than what is typical.

Cellular amplifiers are available for the home, car and office. These amplifiers boost 3G and other cellular signals and decrease the possibility of dropped calls. With the increase of 3G data card use for mobile computing, these amplifiers also come in handy for data communications.

The 3G network dilemma doesn’t mean that consumers shouldn’t avail themselves of cool gadgets like the iPhone. They can, however, increase their enjoyment by taking advantage of improved cellular reception from other cool gadgets like amplifiers that allow them to use these cell phones without issue.

Do You Have A Cellular Signal Amplifier For Your Vacation?

Summer is drawing to a close, and many Americans are taking their final vacation of the season. It is evident that summer travel plans have shifted this year because of the current economy. Rather than hopping on a plane or traveling across country, people have been altering their vacation plans by staying closer to home and taking road trips, which can be shorter and are traditionally more budget-friendly.

Having access to a cell phone and being able to stay connected while on vacation has become a key component found in today’s American vacations as well – as long as travelers can get and maintain a cellular signal. With a cellular connection, families can log onto travel Web sites to check the latest prices for hotels and activities, use Google Maps to get directions to that bed and breakfast tucked away in the mountains, stay connected to work or friends through calling, text messaging or e-mail, send vacation pictures or video directly to others, play both connected and traditional mobile games, or download the latest music to pass the time.

However, the problem of poor cellular signal reception is even more evident while traveling. With spotty cell reception, travelers lose access to online tools, data and calls. If a cell phone has poor reception that makes for spotty calls and data access, a summer vacation can easily turn into a hassle, leaving families frustrated and alone. Adding a cellular signal amplifier to a car, RV or boat can help traveling families ensure that they have a constant cellular signal for routine communication, or in case of emergency. With an amplifier, consumers can have the freedom to vacation in remote areas, while making sure they stay connected for fun, convenience and safety.

Sirius & XM Satellite Radio Coverage Map?

SiriusXM Satellite Radio Coverage Map

Has the Sirius / XM customer service improved helping customers upgrade to the latest software versions? I was becoming increasing frustrated by the poor reception / coverage I am received on my Sirius Satellite radio S50 until I upgraded my software. Why is Sirius XM is losing signal for no reason?

As a huge Howard Stern fan if you miss a few seconds you might miss the entire punch line of a joke and its annoying. Unlike cell phone signals where the signal drops and you call is gone. Satellite radio just cuts in and out when you start entering an area where there is a poor view of the sky or you are on the edge of the terrestrial repeater network. I live in one of the largest most heavily populated cities in the U.S. (Los Angeles) and can't believe that I could be on the edge of a repeater network with such a large concentration of customers. After upgrading my S50 to the latest software my signal improved and I didn't need to start another web site similar to DeadCellZones.com to allow other frustrated Sirius and XM radio to complain about poor signals. Apparently a lot of other customers had a similar problem due to all of the comments below.

This coverage map does not reflect the terrestrial repeater coverage - the signal around most major metropolitan regions in the U.S. is much stronger due to the repeater network. A repeater is a ground-based broadcasting station. A repeater's signal coverage appears to be stronger than the standard satellite signal with approximately a 20 mile radius. The selection between picking up the terrestrial or satellite signal is automatic, and the radio will pick up whichever is significantly stronger. You can see whether your antenna is connected to a repeater by going into the radio's menu, selecting "antenna aiming", and seeing the two bar sets. The one marked "T" or "Terr" is the terrestrial repeater signal. If that is around one bar, it would probably be best to aim your antenna towards the nearest metro area to get the best signal.

Some people have satellite radio reception trouble if they live on the edge of a repeater signal, where both the terrestrial and satellite signals are equally strong for much of the day. If this is the case, it would likely be a good idea to shield either the side or top of the antenna with something metal to allow it easily select one signal or the other. This is likely an issue that will be resolved with newer generation radios.

Dropped Call Etiquette

How many times have you had a dropped mobile phone call and played phone tag trying to reconnect the phone call? Each time I always wonder if the person I am talking to is going to call me back or I should call them. Well, I saw this post on a Richard Wolpert's blog and think this etiquette is spot on and should be shared with the entire world . . .

If you are on a cell phone call and the call gets dropped, the proper etiquette is that that person that initiated the call in the first place calls the other one back. No dual dials. No dual voice mails. No delays to get the call going again. Its really this simple.
  1. if you initiated the call and it drops you call the other person back.
  2. if you received the call and it drops you just wait for the call back.
Please pass this along or forward the link to this post to everyone you know. It will save us all time and frustration.

8000 Total Dead Zone Complaints & Growing!

After launching DeadCellZones.com back in 2000 we have received almost 100,000+ coverage complaints from the big 4 carriers. We currently have 8,000+ user generated complaint locations on our maps since we converted from a database driven complaint form in October of 2007. We try and keep the data fresh and only maintain a complaint in our database for 3 years or whenever a carrier fills gap with additional coverage and updates the location. We typically receive between 20-1,000 daily complaints posted to our map while averaging between 200-1000 unique visitors per day through. Over the last few days we have received 2,300+ new coverage complaint locations (from 20,000 unique visitors) after Kim Komando did a story on "Avoiding Dead Zones" on her syndicate radio show to more the 2.5M people. Our users find us through primarily organic search and word of mouth. Thanks to our user generated support here are our monthly unique visitor numbers below . . .

Can Femtocells Fix U.S. Residential Cell Phone Coverage Problems?

A femtocell—originally known as an Access Point Base Station—is a small cellular base station, typically designed for use in residential or small business environments. It connects to the service provider’s network via broadband (such as DSL or cable); current designs typically support 2 to 5 mobile phones in a residential setting. A femtocell allows service providers to extend service coverage indoors, especially where access would otherwise be limited or unavailable. A number of non-U.S. operators have announced intention to have field trials in 2008, including O2, Softbank, TeliaSonera and Vodafone. Most analysts agree that 2008 will primarily be field trials and soft launch, while commercial launch will be commence in 2009. When will the U.S. carriers get their act together and catch up to the rest of the world?

Google Balloon Cell Towers?

Space Data Balloon Cell Phone Towers

Google is considering working with, or buying Space Data Corp, a company that provides wireless services via Balloon, according to the WSJ. Space Data Corp hires local residents to launch weather balloons filled with hydrogen. The company targets areas without existing internet access, such as rural areas and highways, providing wireless and internet services to truckers and rural folk. The company currently launches 20 balloons a day, and a single balloon can service an area equivalent to 40 cell phone towers. The balloons cost $50, however the transceivers attached to them cost $1500, but parachute back to the earth once the balloon is no longer in service. See the WSJ video on TechCrunch. What happens when one of these balloons drifts into the engine of a jet airplane? How reliable is it and what is the capacity?

Wifi or Wimax the future of cellular?

I can completely understand why a coastal town like Cambria, CA does not want to install a an old cell phone tower that might someday be replace by Wifi or Wimax. Range of and capacitiy have been major limitations for existing cell tower solutions. I am not an engineer but it would seem that if a cell down can only reach customers over a few square miles than the technology is probably old. I have heard Wifi and Wimax tests have proven to work up to 100 miles. I also know how to make a phone call using VOIP. So if you add 1+1 together you get a Wifi / VOIP mobile phone. Is it going to take an innovator like Google to enter the wireless carrier business before existing carriers will wakeup and invest in the future? Google does know how to provide a good service to its customers and monetize that experience through advertising profitably. Why can't the same be done with free mobile phones?

Smaller Towns Gaining The Attention Of Wireless Carriers

I love this article that was published today on a small town of 6,500 residents in Central California regarding the lack of cell phone coverage in their town. The number of cell sites has grown from 96,000 in 2000 to 210,000 in 2007, according to CTIA, the telecommunications industry's trade group. How many more sites do we expect to see in the next few years?

We apparently don't have any Cambria, CA readers of our web site DeadCellZones.com because we do not have any complaints posted on our site yet. Carriers look at our web site everyday and would recommend to any other small town around the U.S. to post a complaint on our map so their complaint can get heard.

What Is The Largest U.S. City Without Cell Phone Coverage?

A wealthy beach town on the Central Coast of California still does not have cell phone coverage? I was amazed when a reporter from the LA Times called me today who is doing a story on Cambria, California's five-year battle to get cell phone towers built in their city of 6,500 residents to improve cellular coverage. She had a question that I could not answer but might by opening up the discussion to our users. What is the largest (most populated) city in the U.S. without cellular coverage?

Why Is Mobile Coverage So Much Better Overseas?

The FCC licensing rules for cellular frequencies requires that networks only sell and use equipment that works on their specific frequency. Carriers can’t install cannot make any cash selling repeaters to their customers in the U.S. so why bother when the FCC prevents innovation? By contrast, in Asian countries like South Korea repeaters are installed in every apartment complex, shopping mall, and even on street corners. Unless the FCC makes an exception for repeaters, it’ll be a while before we see similar market penetration here in the States. See related article
