Lord Young

LORD Young, the Trade arid Industry Secretary, made three announcements to take the UK mobile phone market into the 1990s: extending the extra ETACS cellular channels to the M25, four Telepoint licences and a discussion document to help shape new systems. Britain's liberal and competitive telecommunications
policy had made Britain a world leader in the introduction of mobile phones, leading to an estimated
500,000 cellular radio users.;, · But this growth had brought problems: "Congestion has inevitably affected the quality of service, especially around the M25.More channels
.
"That is why we are making more widely available 400 extra radio channels,
released by the Mini.stry of Defence, around the M25. Tqgether with
. further investments being made by the · operators, that will help ease the difficulties
of cellular users." However, cellular radio was not for everyday use in the High Street: "This is
. where Telepoint comes in. Users will have their own personal cordless
phones -- small enough and light enough to be carried in a pocket or handbag
... it will be like having a phone box in . your pocket." ·· ·· ·
Lord Young introduced · his department's discussion .document,
• Personal Communications in the 1990s, . saying it was to stimulate views. It proposes
at least two new operators for new systems, called Personal Communications
Networks, at 1. 7 to 2.3 GHz. He said: The new systems ... would
take account of the trend towards mobile office equipment -- fax machines, word
processors, calculators and so on -leading to the 'office in the pocket'. They would use digital tech·nology to transmit data messages as·well as conversation.
"All sorts of people, in all sorts of situation, would be able to use them. For instance, people expecting an important call would still be able to get out and about. People who witness an accident or crime could contact the emergency services right away. Shopper and commuters would be able to ring home or
· office from an}'where. ·People, espeially women,'T otJt at night or feeling under threat, couldd have the added reassurance of CT1 phone in the pocket or handbag.
