Mobile Blackspots Map for the UK


We are huge fans of the fact that Vodafone will start advertising femtocells.  It's impressive to see Vodafone stepping up and taking the industry lead educating consumers about the new products to consumers in the UK using the brand Sure Signal.  Vodafone's Sure Signal guarantees you a great 3G signal at home, no matter where you live, and promotes the fact it might be an emergency risk if you are living in a coverage hole.  This is something the U.S. carriers have tried their hardest to ignore.  See their promotions and website above and watch the stories of people from around the UK who have been rescued from their mobile signal problems.  I am quite proud of a carrier finally admitting that they have coverage holes and giving consumers the ability to do something about it.  Kudos to Vodafone UK!

It will remain to be seen if the U.S. carriers still want to "blow smoke" up our asses with their ridiculous commercials touting their great coverage.  AT&T, T-Mobile, Sprint & T-Mobile have been dragging their feet for years "testing" femtocells in the U.S. and not educating their customers that they actually exist.  It also amazes me that Vodafone owns 45% of Verizon in the US yet it seems so against Verizon's arrogant culture to admit they actually have coverage problems with their network.  Do you think Verizon's marketing executives who came up with their moronic coverage map promotion commercials are going to be able to keep their jobs or are they going to have to do an "About-Face" (look in opposite direction) if they start selling femtocells in the U.S.?  Hmmm . . . we shall see.

As a result of Vodafone's leadership, Deadzones.co.uk has launched a new "Consumer Generated Mobile Blackspots Map" asking where mobile customers don't have problem areas indoors and outdoors.   Even if Sure Signal can solve the problem indoors at your home or office there are still many bad patch locations around the UK.  We ask for users to contribute pins in our map for 3, O2, Orange, T-Mobile, and Vodafone.

Underutilized Spectrum

Where Is Spectrum Underutilized and Who Owns The Local License?  

Underutilized wireless spectrum refers to portions of the radio frequency spectrum that are allocated for specific uses but are not fully utilized or efficiently utilized. The radio frequency spectrum is a limited and valuable resource that is used for various wireless communications, including cellular networks, Wi-Fi, broadcasting, satellite communications, and more.

There are a few reasons why certain portions of the spectrum may be underutilized:

Regulatory Constraints: Some portions of the spectrum are allocated for specific uses or licensed to specific entities. If those entities are not fully utilizing the spectrum, it can result in underutilization. Regulatory barriers or restrictions can sometimes prevent efficient allocation and utilization of the spectrum.

Fragmentation: The spectrum is divided into different frequency bands, and different technologies and services may operate in different bands. Fragmentation can occur when certain bands have limited adoption or deployment, leading to the underutilization of those specific frequencies.

Technological Advancements: The deployment of newer technologies and more efficient communication protocols can sometimes render older spectrum allocations less efficient or underutilized. For example, advancements in compression algorithms and spectrum-sharing techniques can make better use of available spectrum.

Regional or Geographic Variations: Spectrum usage and demand can vary across different regions or geographies. Some areas may have a higher demand for wireless services, leading to more efficient utilization of the spectrum, while others may have lower demand, resulting in underutilization.

Efforts are being made to address underutilized spectrum and improve spectrum efficiency. These include spectrum auctions, spectrum sharing policies, dynamic spectrum allocation, and the development of new technologies that can make better use of the available spectrum. These initiatives aim to maximize the use of the spectrum resource, improve wireless connectivity, and support the growing demand for wireless services.

FCC Could Ban Cell Signal Boosters = Bad Idea

People Don’t Seek Solutions Unless There Are Problems!

Comments on the RCR Wireless Article FCC to address cellphone boosters, jammers and is the FCC losing its' authority and credibility based on this court ruling?

The Federal Communications Commission is considering implementing a law that would make cellphone boosters illegal unless they are deployed by a wireless operator (DCZ:  Wireless operates hate signal boosters b/c they are not under their control)  or with the consent of a wireless operator, a move that could impact thousands of end-users already owning such devices.  (DCZ:  What problem are they trying to solve that the network operators have not dealt with for years?)

The Notice of Proposed Rulemaking before the FCC addresses an ongoing controversy within the wireless industry and could impact devices like MagicJack (DCZ: this product is not a booster its VoIP.  However, they have a product called FemtoJack under development) and other femtocell solutions, as well as local and state governments that want to be able to use cellphone jammers to prevent prisoners from unauthorized use of cellphones. (DCZ:  Or schools who want their kids paying attention to the teacher)  Depending on whose argument you believe, the eventual ruling could even have an impact on net neutrality rules.  (DCZ:  I don't see how this applies to Net Neutrality)  One proponent of signal boosters and jammers said that making boosters illegal won’t address the products already in the market, nor will it stop the sale of signal boosters.  (DCZ:  There are a handful of big companies and thousands of people employed by them with hundreds of thousands of devices already on the market.)

Wireless industry trade association CTIA in 2007 filed a petition for a declaratory ruling at the FCC, asking that it outlaw the sale and use of any device that can enhance or impair cellphone calls. (DCZ:  Might have worked under the previous corrupt Bush Administration)  The petition was a surprise to some third-party retailers, who called RCR Wireless News at the time and thought the story had to be wrong. Therein lies the crux of the problem: a cellphone booster can enhance coverage for a customer, but also has the potential to interfere with someone else’s signal (DCZ:  How often and how can they prove this?). Yet, cellphone boosters have been marketed to carriers and end-users alike as a way to improve the cellular signal in areas where coverage is less than satisfactory – and the reality remains that cellphone coverage in some locations is spotty.  (DCZ:  Carriers need to get their act together with Femtocells first before they decide to outlaw something like this. Signal boosters provide a lot of value in the car.)

The FCC’s definition of signal boosters is fairly broad as it includes amplifiers, repeaters, boosters, Distributed Antenna Systems, and in-building radiation systems that enhance CMRS signals or Part 90 signals. CTIA is asking that the commission rule that companies must have an FCC license to operate a signal booster or have the consent from an FCC licensee (i.e., operator), and that the sale and marketing of devices to unauthorized parties (i.e., end-users or commercial building owners) is illegal.

CTIA also says that wireless microphones, jammers, and new products like the MagicJack femtocell device also are threats to the network.  (DCZ:  What happened to let entrepreneurs create technology to help the industry progress?)

“Unlike wireless handsets, which are under the control of the wireless licensee’s base station, signal boosters cannot be controlled by wireless licensees. However, it is clear that the commission’s rules require carriers to control and govern the use of signal boosters and amplifiers. In fact, this control contemplated in the commission’s rules exists for very good reasons. Signal boosters, because they are not controlled by the base station, do not operate at the lowest possible power. Rather, these devices are intended to operate at much higher power, which raises the noise floor, harming spectrum efficiency and causing interference that leads to degraded or dropped calls unless the devices are properly installed and overseen by the carrier,” CTIA said in comments on the NPRM.

“To address the harm caused by unauthorized signal booster operation, the commission must affirm its existing requirements, which prohibit the sale or marketing of signal boosters to unauthorized users. Currently, many manufacturers and retailers market and sell these products to end-users with the knowledge that these devices do not and cannot comply with the commission’s licensing and interference control obligations. Under FCC rules, the use of signal boosters is only permitted by licensees or parties authorized by licensees. However, illicit sale and operation of these devices will continue to proliferate – and will be impossible to effectively enforce – if the commission does not take prompt action to affirm these requirements.”

Not everyone agrees. Howard Melamed, CEO of CellAntenna, said a blanket “make them illegal” mandate doesn’t solve the problem. It will just force end-users in need of a solution to buy products overseas. “People don’t go out seeking a solution unless there is a problem.”

Howard said some of his clients are hospitals that have needed coverage but not been able to get satisfactory coverage from the carrier. Instead of a blanket mandate, the FCC should force signal-booster manufacturers to tighten the design specifications. He’s also advocated that a registry be created where people can register their signal booster with the FCC so in the event the signal booster is affecting the network, the carrier can know who or what is causing the problem. Melamed also joked in an interview with RCR Wireless News that he is a “persona non grata” within the wireless carrier community.

Wilson Electronics in its filing with the FCC argued that mobile amplifiers should not be subject to the same rules as larger, traditional fixed power boosters. Wilson also said the mobile boosters, designed for personal use in a car, for example, are an example of net neutrality initiatives at the FCC that are designed to allow any device to attach to the network.

CTIA disagrees with that assessment, as well as comments filed by The DAS Forum that recommend a code of conduct is followed, rather than more regulation.

Both CTIA and Howard agree that poor-quality boosters can cause problems. But Howard argues that not allowing U.S. companies to sell boosters that meet FCC certification standards will only lead people and businesses to buy poorer quality boosters overseas. Signal boosters are sold throughout the rest of the world, he said; the controversy only is occurring in North America.  (DCZ:  Pointing the finger in the wrong direction)

Jammer issues

But cellphone boosters are only half of the FCC’s notice of proposed rulemaking. The commission is also reviewing the sale of cellphone jammers, which block signals. Jammers can only be sold to federal authorities under the way the law reads today. Melamed argues that state and local authorities need to be able to use jammers, especially in a society where cellphones are used to remotely detonate bombs and are the No. 1 device illegally snuck into prisons. However, the FCC may not be the final authority on the use of cellphone jammers at the local and state levels. The Senate in October passed the Safe Prison Act, which allows the director of the federal bureau of prisons or the CEO of a state to seek FCC approval to deploy cellphone jammers in their jurisdictions to block wireless coverage in correctional facilities.

RV Cell Phone Signal Booster

An RV (aka Recreational Vehicle) on the move can have significant cell phone coverage problems depending on the location it's traveling in. A good way to minimize dropped calls and increase reception to cellular phones/broadband data cards is to install a Cellular Repeater Kit on the roof. A Cellular Repeater Kit will allow you to make calls when very little cell phone signal exists or one or two bars. This booster will also reduce dropped calls and increase internet speeds. We have heard of lots of success stories with Wilson Electronics Repeater kits customized for use in Motorhomes & RVs. Wilson Electronics is well regarded in the industry because of its high quality.

Cell Phone Boosters or Repeaters are very simple to set up and they do not require expert installation. A Repeater kit consists of 3 major components; an external antenna, an amplifier or booster, and an internal antenna that gives cellular coverage inside the RV.  Kits can range from $300 Single Phone Booster for a single-phone style amp to $600 Multiple Phone Booster for a more powerful amp that can support multiple cell phones and/or broadband data cards.

  A few of these kits are listed below for a Single Cell phone and Multiple Cell Phones or Data Card:

Verizon Femtocell Sells For $249


After all of the "Can You Hear Me Now Commercials" and "AT&T Coverage Map Bashing"  Verizon Wireless still has incredible amounts of Dead Zones to fill in. You would never know from their misleading commercials but less than 50% of US homes have seamless wireless coverage and could use a femtocell to improve home coverage.  However, in order to improve Verizon's coverage in your home you the customer must pay for your own personal mini cell phone tower at a cost of $249.  Keep in mind Verizon's femtocell is only 2G as well and not 3G currently.   

Sprint was one of the first carriers to launch femtocells with Sprint Airave (awful close to the trademark name Airwave) in 2008, but Verizon was not far behind in bringing femtocells to the masses with a Verzion Wireless Network Extender in January of 2009.  AT&T 3G Microcell is also in trials in North Carolina, Georgia and San Diego and is expected to launch nationwide sometime in the Spring of 2010.  T-Mobile is also in trials with Ubiquisys and Huawei and is expected to launch something this year as well.  The black box will send out a CDMA signal covering up to 5,000 square feet of the home or office with support for up to three simultaneous calls. Like Sprint's solution, the Wireless Network Extender uses GPS to verify that you're not creating little tiny Verizon networks outside the U.S. and plugs into the internet source of your choice via Ethernet. It'll be available in Verizon stores and online for $249.99. Pretty expensive if you ask me and not clear if an additional monthly subscription or long term contract goes with it.  We have only read reviews online that are quite negative about the price but would like to hear from consumers who actually use the product in our comments section below. 





Be aware of the pros and cons with cell reviews allowing you to compare before deciding on a mobile phone purchase.

AT&T Coverage Map Helmet Video


We need to hire this guy ASAP!   This is one of the funniest videos we have ever seen making fun of the marketing departments for both AT&T and Verizon.  This is a brilliant way to exacerbate the feud going on between Verizon and AT&T in regards to mapping coverage.  This brilliant person had the creativity to make his own coverage map helmet that shows AT&T's coverage nationwide and went into stores trying to find a phone that could get him coverage in rural areas.

He enters an AT&T store to get some assistance and then goes into a Verizon store where he is greeted to a bunch of humorous talk from employees who drink the "coo-laid".  Kudos to him as he definitely managed to stir up some attention as he even walked around to a local movie theater where people complimented him and honked in support. He was so cool almost like Will Farrel and did a wonderful job in keeping his composure when questioned about the idea.  In the end, he was unable to find the provider or phone that he was looking for.

Here is the commercial that he is clowning.  

Cell Phone Signal Booster FCC Certification Standards

Published by Quantum-Wireless on February 04, 2010

Wilson Electronics has asked the Federal Communications Commission to raise its certification standards for cell phone signal boosters to prevent interference to service providers’ networks and equipment while increasing customer satisfaction.

In November 2009, Wilson submitted a ‘Petition for Rulemaking’ to the FCC recommending additional tests that cell signal boosters must pass in order to meet FCC certification standards. Some details include more testing on feedback detection and auto-shutdown to prevent interference with cell towers. Wilson also wants more stringent controls on proximity detection and auto shut down to prevent signal overload of cell towers.

“At the root of this issue is that we’re all trying to provide customers with better cell phone coverage and service,” said Joe Banos, Wilson's chief operating officer. “We strongly believe that raising the FCC certification approval standards for cell signal boosters would protect the performance of cell towers and prevent service disruptions that can be caused by some unsophisticated cell phone signal boosters in service today.”

Wilson also called for bi-directional signal amplification. Some signal boosters amplify only the incoming signal but do nothing to increase the phone’s weak signal transmission back to the tower where amplification is needed most and bi-directional signal amplification would remedy this problem.

Weak Home Cell Phone Signals

1. Rural areas
In many rural areas, the housing density is too low to make the construction of a new base station commercially viable. In these cases it is unlikely that the service provider will do anything to improve reception, due to the high cost of erecting a new tower. As a result, the only way to obtain strong cell phone signal in these areas is usually to install a home cellular repeater. In flat rural areas the signal is unlikely to suffer from multipath interference, so will just be heavily attenuated by the distance. In these cases the installation of a cellular repeater will generally massively increase signal strength just due to the amplifier, even a great distance from the broadcast towers.
2. Building construction material

Some construction materials very rapidly attenuate cell phone signal strength. Older buildings, such as churches, which use lead in their roofing material will very effectively block any signal. Any building which has a significant thickness of concrete or amount of metal used in its production will attenuate the signal. Concrete floors are often poured onto a metal pan which completely blocks most radio signals. Some solid foam insulation and some fiberglass insulation used in roofs or exterior walls has foil backing, which can reduce transmittance. Energy-efficient windows and metal window screens are also very effective at blocking radio signals. Some materials have peaks in their absorption spectra which massively decrease signal strength.
3. Building size
Large buildings, such as warehouses, hospitals and factories, often have no cellular reception further than a few meters from the outside wall. Low signal strength is also often the case in underground areas such as basements and in shops and restaurants located towards the centre of shopping malls. This is caused by both the fact that the signal is attenuated heavily as it enters the building and the interference as the signal is reflected by the objects inside the building. For this reason in these cases an external antenna is usually desirable.
4. Multipath interference

Even in urban areas which usually have strong cellular signals throughout, there are often dead zones caused by destructive interference of waves which have taken different paths (caused by the signal bouncing off buildings etc.). These usually have an area of a few blocks and will usually only affect one of the two frequency ranges used by cell phones. This is because the different wavelengths of the different frequencies interfere destructively at different points. Directional antennas are very helpful at overcoming this since they can be placed at points of constructive interference and aligned so as not to receive the destructive signal.
5. Diffraction and general attenuation

The longer wavelengths have the advantage of being able to diffract to a greater degree so are less reliant on line of sight to obtain a good signal, but still attenuate significantly. Because the frequencies which cell phones use are too high to reflect off the ionosphere as shortwave radio waves do, cell phone waves cannot travel via the ionosphere.
