"The first UK public mobile radiotelephone service was instigated in February 1949 on an experimental basis and then opened for full service in July 1949 and provided connection to the UK telephone system for ships in the Thames estuary
It had 6 channels 157/161.5Mhz 157.1/161.5Mhz 157.2/161.6Mhz 157.3/161.7Mhz 157.4/161.8Mhz 157.5/161.9Mhz and it was an AM system."
It looks like the Duke of Edinburgh had a radio telephone in 1953 sometime
83. The Duke had an early version of a mobile telephone, made by Pye Telecommunications of Cambridge, fitted to his car in 1953. He installed an improved version provided by the AA (of which he was President at the time).
But it didn't appear on his suppliers list till 1957
Experimental Radiophone service in South Lancashire:—
Calls in Service area 2s. 6d. for 3 minutes
From 1st September, 1960: 1s. 3d. for 3 minutes
Calls to or from places outside Service area
Trunk charge plus radio fee of 2s. for 3 minutes
From 1st September, 1960: Trunk charge plus radio fee of 1s. for 3 minutes
Experimental Radiophone Service
Miss Pike I think the hon. Member has in mind the experimental radiophone service in South Lancashire. Fifty-four vehicles are now fitted with these telephones. The service is growing, but not as rapidly as I should like. Nor is it as yet economic. As to our future plans, I would refer the hon. Member to the detailed information which the Postmaster-General is circulating in today's OFFICIAL REPORT.
Mr. Mason Is not the hon. Lady aware that it is not growing because it is not a satisfactory service? Is she not aware that a customer has to pay £200 for a set, it costs £30 in licence fees, and 10d. per minute to use, and that there is no privacy, no secrecy in using this telephone instrument? It is commonplace to listen in on cotton deals, sales of machinery, and private and intimate personal conversations. If the hon. Lady does not do something about ensuring secrecy on these telephone instruments, then telephone tapping in this service may even become a business.
Miss Pike This new service is having teething troubles, but my right hon. Friend is looking at it carefully.
Car Radiophone Service, London
Mr. Mason asked the Postmaster-General what moneys he intends spending on the radio base stations for a car radio phone service in London; what demand has been made for such a service; whether he has received any encouragement from the service he established in the Manchester area; and if he will make a statement.
Mr. Bevins I expect the base stations for the London car radiophone service to cost about £20,000 and the number of installations to be about 3,000 when the service is fully developed. Demand for the South Lancashire service has been disappointing but my estimate of demand for the London service has been based on inquiries of potential customers, and I am satisfied that it is a reasonable one.

paraphrase from "The mobile phone book" by Ericsson isbn 0952403102 1994
....The next step was to settle the matter of standards, a decision had to be made in concert with British Telecom. BT first favoured a system devised by Siemens, but Racal said "No we want AMPS"...
...Racal wanted AMPS with 25Khz rather than the US 30Khz channel spacing, It realised that the cost of entry (from a mobile phone users point of view), would be critical to the success of the business, and a major part of that cost would be the price of the mobile... It reasoned that having US volumes to get prices down would be important.
So BT abandoned the German idea, and took up a french idea - But it really was no more than an idea, with very little substance, and Racal said again "we want modified AMPS"
Still BT would not give in. Its next proposal was the Nordic 450 standard, proven in use since 1981. But, thought Racal, NMT would never handle the volumes that that AMPS would, and volume would be important to justify the the cost of infrastructure as well as for the mobile station prices...
Racal also thought there was a security problem with NMT, which could make certain types of fraud possible.
So Yet again Vodafone said "We want modified AMPS", and finally the parties agreed.
Today (1994), cellnet agrees that the choice of a 'country cousin' of AMPS was a remarkable piece of insight and vision
Ericsson won the "turnkey" contract to Racal Vodafone, beating Motorola and AT&T, because of its large capacity fully proven AXE digital switch according to the Ericsson book.
BT placed its order with Motorola....with smaller switches optimised for typical US towns.....So BT had some difficulties when ... the systems were loaded up
1984 - extract from http://www.retrowow.co.uk/retro_collectibles/80s/mobile_phone.html
"Sorry to burst the celebrity bubble of Ernie Wise making the first cellular call on 1st January 1985 - As Beta testers we were using them from December 24th 1984 as part of the final test regime for the first Cellnet site on the Post office (BT) Tower."
"I recall taking myself to first Wrotham Hill , then Detling Hill to determine the max range of this first cellsite that was 'top hating' London with the first TACS cells using the GO-Phone 2000 badged NEC 'Banana phone' with the first two allocated phone numbers to BT Securicor 0860 326000 and 326002. We have come a long way in 25 years...." John
"Ernie Wise and Beta testers! The BT Cellnet system was switched on in the autumn of 84 for one week to cover Maggie hosting a G7 summit in central London before its true launch in Jan 85. I was there had a motorola carphone in my car on the Monday morning and had arranged 12 appointments to pre-sell them to existing radiophone(system 4) users. I made the first commercial call and sold the first commercial phone at 7.00 am. " Stuart 28/05/2012

The networks themselves were small; Vodafone had just a dozen masts covering London and the M4 corridor while Cellnet launched with a single mast, stuck on the BT Tower.
1985 Jan 31st new scientist article showed...
In 1985 THE INTRODUCTION OF CELLULAR RADIO IN THE UNITED KINGDOM DAVID M BARNES says
"In June 1982 the UK Government announced the terms and conditions for two competing national cellular radio network"
The decision in the UK to adopt the TACS system ....criteria of most contending systems such as NMT,MATS-E, C-900 and NAMTS"
"The choice of the UK system was announced in Feb 1983"
"Initially coverage of London was seen as the most important factor and the Cellnet Network commenced commercial operation in early January of 1985 with 15 base stations serving the London area. By mid March of 1985 the network has a total of 27 base stations serving the London area and in addition service is also provided in Birmingham, Manchester and Liverpool"
"In the centre of London cells of typically 2 km radius are employed with medium sized cells (typically 4 km radius) on the outskirts of London"
"It was expected that some 1000 subscribers would be registered at the end of the first month of service but this milestone was in fact reached after the first three weeks of service. After some two and a half months of service the total number of subscribers is over 3000. This is resulting in some 3000 calls being generated on the network during the busy hour and channel capacity has already been increased on some sites."

The cellular systems business continued to grow rapidly, and several joint ventures were established.
In the United Kingdom, Cellnet awarded Motorola an order valued at about $150 million for analog cellular network expansion.

ERICSSON WINS MOBILE NETWORK CONTRACT
Ericsson has won a GBP27 mil contract for expansion of the B-network mobile telephone network in Shanghai, China. The contract calls for the installation and supply of CMS 8810 ETACS network equipment. The expansion will raise capacity of the network to over 50k subscribers.

At the end of March 1996, Cellnet - the company jointly owned by BT and Securicor - had almost 2.4 million customers (up 655,000 in the year) and the number grew by about three per cent a month.
Mobile customers are also benefiting from substantial price cuts of up to 30 per cent which became effective in March. Prices of digital calls were reduced, off peak time was increased and per second billing was launched.
