The BBC is conducting a leading consult in to the state of mobile phone coverage in the UK.
Over the march of the next month, the plan will endeavor to map out the accessibility of 3G and 2G services up and down the country.
Mobile operators offer their own coverage maps but no eccentric consult has nonetheless been carried out.
Measurements will be done using an app created by network review definite Epitiro.
The program may be downloaded by any person with an Android handset and will record lane turn coverage opposite Britain.
At the finish of the assessment period, the BBC aims to manifestation the results on a clickable map.
"Coverage is the number a situation for consumers," mentioned Gavin Johns, arch senior manager of Epitiro.
According to Ofcom, there are over 12 million smartphones being used around the UK and a great service is crucial is to web browsing that more and more people urge from their handsets.
"Our coverage app will give the data consumers must be see if 3G services are existing and from that mobile operator. As mobile broadband is critical to many of us, you hope people proffer and make the plan a success," mentioned Mr Johns.
Most people have an version about bad mobile coverage and it depends on a accumulation of factors inclusive either the user is inside the building or out and what time of day they are using the network.
When a phone connects to high-speed 3G broadband services it will typically manifestation a 3G or H pitch by the vigilance bars. The UK's median mobile download speed is 1.5Mbit/s. In areas of great 3G coverage, that figure rises to 2.1Mbit/s.
Alternative technologies add EDGE, that has a limit speed of 0.3Mbit/s. Phones typically manifestation an E pitch when using the system.
When consumers obtain a round or 'o' pitch it is doubtful that broadband services will work satisfactorily, in any case of the number of vigilance strength bars.
Coverage is an situation that regulator Ofcom describes as a priority. It estimates that in conditions of home mass, 91% of the UK has 2G coverage and 76% has 3G coverage.
It is conducting its own tests on UK mobile notspots - areas of low or no service. The investigate is due to be published after that this year.
A expert report, consecrated by Ofcom stated: "More data on coverage is required, and this should be in a stereotyped format enabling more aged between user services such that users can make an sensitive preference about coverage in their area.
"Whilst postcode-based checkers go a few way to this, their correctness is paltry to the indicate at that they have paltry value."
O2's arch technology officer Nigel Purdy agrees that the stream coverage checkers that rest on predictive modelling are not wholly accurate.
His company, along with other operators, conducts its own, more in-depth tests - inclusive drive-bys - to see what coverage is similar to in a specific area and to plan where to place new bottom stations.
The dare is "to obtain that data in a format for easy access for our customers," he said.
A similar plan to map mobile vigilance strength globally has been carried out by opensignalmaps .
Operator 3 is mission for change in the way consumers are sensitive about coverage.
"There is no familiar typical for measuring coverage and a few operators lend towards to grossly exaggerate. We similar to to succeed people's expectations," mentioned Phil Sheppard, 3's director of network strategy.
One of the greatest challenges for 3, that owns high magnitude 3G spectrum that is not great at perspicacious buildings, is ensuring coverage when people use their phones indoors.
The complaint will be solved, to an border by attainment access to descend magnitude spectrum that will be liberated up by the digital switch-over.
Ian Fogg, an eccentric telecoms analyst, mentioned that all operators strive with indoor coverage.
"It is ample simpler to envision outside coverage. Indoors it will depend on the make up of the building. Thick solid walls will inhibit signals ample more than a wooden structure," mentioned Mr Fogg.
As homes become ever more energy-efficient, so the complaint is exacerbated as rarely insulated houses lend towards to inhibit mobile signals.
Spectrum that will enable 4G services is not due to be expelled until at least 2012.
Meanwhile 3 is active adding more bottom stations. It right away has 12,653 sites around the UK. It site-shares with T-Mobile and will earn more locations subsequent to the T-Mobile and Orange merger.
But mobile masts bring their own challenges, according to Mr Purdy.
"Everyone craves great coverage but when you stone up to erect a site nearby them it can result in problems," he said.
In city centres, where more masts are indispensable at roof-top level, the dare is anticipating a fitting let price, he added.
The BBC consult will not portion speeds, but this is apropos increasingly crucial as people use their handsets for downloading and web browsing.
Ofcom, in conjunction with Epitiro, not long ago carried out a national test.
In those speed tests, O2 and Vodafone came out on top, averaging between 2 and 3Mbit/s, compared to Orange that managed between 1Mbit/s and 1.5Mbit/s.
Broadband more aged website Top10.com expelled its own 3G speed app this year and it found that Milton Keynes had the slowest 3G speeds at around 1.73Mbit/s compared to 3.6Mbit/s in Peterborough.
Mr Fogg thinks that, if sufficient people download the UK mobile map app, it could fool around a profitable purpose in assisting upgrade coverage.
"One of the key solutions is identifying the problem. X network's may usually be awful in certain locations and this consult will give improved data for operators," he said.
