Swedish Telecom did not actively market the service. It requested that it should be self-financing and at the same time prices should be low enough to attract at least high-paying customers. MTA remained a regional system, in Stockholm, Gothenburg and MalmoВЁ , with some 110 users, and was phased out in 1969. MTA suffered some substantial shortcomings: the
telephones were unwieldy (40 kg), the service was only regional, the connection times were long and the system was difficult to use. From the early 1950s improvements were studied which determined the new MTB.

Commercial service started in 1965 in Stockholm and Gothenburg, catering for 150 persons. In 1967–68 MTB was further extended, including MalmoВЁ , reaching some 500 subscribers. The system had an automatic speech connection and was based on the principle of dual tone, which
meant that an exclusive selection tone identified the mobile telephone. The transition went to the fixed telecommunications network through the subscriber’s relays with a unique subscriber card for each subscriber. This implied that the system could be used only if the subscriber had a subscriber card at several base stations. A time-out device was built into the system, a tone with increased intensity came on when conversations lasted longer than 3 minutes and continued until the connection was cut off. The weight of the subscriber unit was around 9 kg. MTB was dismantled in early 1983.

And 18 per cent of women have actually texted their beaus a break-up

message, compared to 12 per cent of guys. Anna Saunders, general manager of Fast Impressions Speed Dating, said the use of electronic communication to break up was appalling. “There’s all this new technology that’s supposed to enhance our communication but it’s the contrary,” she said. “Breaking up with someone should be face-to-face.”

Fifty-eight per cent of men and 46 per cent of women agreed, preferring a face-to-face break-up. About 60 per cent of men and women relied on electronic communication as the “safer option” to contact their dates, shunning phone calls. “It’s another barrier you can hide behind before the person bites back,” Saunders said. “A lot of it is probably a symptom of our society. We’re time poor.”

She said text messaging was addictive, although a phone call was probably more efficient. “It’s the lure of the beep beep on your phone and if you start a conversation by text, it becomes harder to pick up the phone.”Saunders said technology was effective only if it was not abused. “When it becomes the main method of contact, the replacement for human contact, then there’s an issue.”

In 1924, there were 1100 stations and the unregulated use of radio frequencies led to chaos. In 1927, a first attempt was made to regulate spectrum usage during an international conference in Washington, it was agreed to allocate the frequency band from 550 kHz to 1.5 MHz to broadcasting. Frequencies below this were allocated to maritime communications. Europe
was lagging behind in the evolution of broadcasting, which had been restricted much earlier through the set-up of public companies such as the British Broadcasting Corporation (BBC). There were some 200 broadcasting stations in Europe in 1929 and broadcasting transformed the wireless industry into a high-volume and low-cost industry, especially through
the market for wireless radio receivers. Until the outbreak of the Second World War, the most important technological developments were made in this field.

The first attempts at true mobile date back to the early 1920s. In the USA in 1921, the Detroit Police Department made the first experiments with ‘mobile’ radio (Noble, 1962). At the beginning, the service was limited to a sort of paging, instructing the police car in question to stop and call back to the police station. These one-way systems were widely used in the
USA. Similar experiments were carried out by the Metropolitan Police of London, though with less satisfactory results (Garrard, 1998). In 1932, the Brighton police force was equipped with radio equipment weighing just over 1 kilo, so that they could be carried by patrolling police officers. One-way messages could be sent to all officers within the range of 6 km. A few years later proper two-way communication features were put in place, but for reasons of weight the equipment could be fitted only to vehicles.

The British police, however, were reluctant to introduce these voice communications systems because of lack of privacy. The police preferred to fit its cars with telegraphy systems during the mid-1930s, telegraphy had the advantage of greater reach (up to 100 km) and was less likely to be eavesdropped, as relatively few persons were able to read Morse signals. The US police was less concerned with privacy, and preferred to adopt voice communication systems. Sweden also equipped its police force with two-way voice communication systems in the late 1930s. Most of the police radio systems at that time worked in the 1.5–3.0 MHz band, which at that time was found to give the best compromise between availability, interference and performance.

Professor Alan Hedge, an ergonomics specialist at Cornell University in New York state, said the condition is caused by “highly repetitive, forceful thumb movements with the thumbs held back from the palms”.

The symptoms are pain in the thumb and region around the base of the thumb and hand. Treatment consists of resting or strapping the thumb, anti-inflammatory medicines, cortisone injections and, as a last resort, surgery. “It’s a bit like the ‘Nintendo thumb’ of the ’90s,” said occupational therapist Andrew Morton.

This transmission via the ‘ether’ challenged the classical notions of physics. Whereas Hertz’s experiments spanned just a

few metres, it was the Italian scientist Guglielmo Marconi who constructed a ‘radio’ that transmitted waves over increasing distance: In 1895, he transmitted signals over a distance of 2.5 km, in 1899 over the English Channel and in 1900 over more than 300 km. Marconi’s greatest challenge was to confute the conventional belief that radio waves propagated only linearly and therefore would be unable to follow the curved surface of the earth. In 1901, Marconi established the first wireless transmission over the Atlantic, spanning
over 3500 km from Cornwall to Newfoundland. Maritime applications become the dominant market for wireless, even though only large and expensive ships could carry the wireless equipment and justify the cost.

At the beginning, only gross pulses of energy could be transmitted, and communications was limited to Morse code. Technological improvements, in particular the refinements in radio communication technology such as amplitude modulation (AM)4 and the invention of the thermo-ionic valve, led to the possibility of transmission of speech and music.

However, wireless equipment was a low-volume and high-cost market. Before the start of the First World War there were some 2000–3000 wireless in use in the entire world, most of them in Britain. At the outbreak of the war in Europe the development of wireless was intensified, again mostly for maritime applications. The applications of wireless for ground-troop applications were still met by scepticism from the military planners, and also because of the bulkiness and weight of the equipment.

These, however, suffered of a series of technical limitations that hampered their widespread use. Only during the 1980s did these problems begin to be surmounted, with the diffusion of cellular mobile telecommunications technology as it is known today. To fully appreciate the technological challenges mobile telecommunications had to surmount to become a widely spread technology, it is useful to briefly sketch the history of the technology in the context of the working principle of wireless
communications. This chapter outlines the main driving forces of the mobile telecommunications industry and how they shape the evolution of the sector and gives some hints on the prospects for the future of the sector.
