Farley, "Mobile Telephone History"
This week's text by Farley covers the history of the mobile telephone. The concept of mobile phones originated before World War II, with New York City public service departments having the use of radio telephones. After World War II, landlines were expanding and some research into
mobile phone communication was expanding. The first mobile radio-telephone
service began in 1946. These were all car based radio telephones. Service began expanding in 1949 when the FCC allowed more frequencies, to the Bell System as well as other companies that wanted to sell mobile service. The first fully automatic service, without the need for
an operator, came in 1948, though the manual operation continued until the late
1960s.
Mobile phone development was slow in Europe compared to the
U.S., but development in Japan was picking up speed. The government sponsored
development, and equipment eventually became exported to other markets. There was not much development during the 1950s, but in the 1960s the Improved Mobile Telephone Service from Bell System was introduced, which operated mostly like a regular telephone. Other countries also began updating their mobile service
during this time. While there was high demand in the U.S., the FCC did not
allow for enough channels to really support much expansion of mobile phones
until the 1970s.
Frequencies were reused in small areas by the Bell System on public payphones to form the first real cellular phones, in metro areas and places like passenger trains. Competition was on the rise in the U.S. in the 1970s, namely between Motorola and AT&T. They began competing to see who could create a working cellular device, such as for dispatch services that Motorola already made
equipment for. Motorola created the first prototype phone in 1973, and this was
the first handheld cellular phone. Meanwhile, Nippon Telephone and Telegraph
was field testing their own products in Japan, and used quality methods that
forced other companies to examine their own quality control and policies. Companies began leaning towards Japanese equipment in their products because of better quality, such as Hewlett-Packard’s use of Japanese chips as they found the worst Japanese chips had a failure rate six times less than American chips.
The Advanced Mobile Phone Service began in July 1978 and six
months later paying subscribers were able to lease the equipment for cars. The
first commercial cell service was offered in Chicago in 1983. One of the first
handheld mobile phones was the Motorola Dyna-Tac. North American mobile systems were analog while Europe worked to create a digital system that worked across all of Europe. European manufacturers began creating a new radio band, Groupe
Special Mobile (GSM), with the first commercial GSM networks appearing in 1991.
Qualcomm developed the Code Division Multiple Access (CDMA) cellular system in
North America. Pacific Telephone invested in Qualcomm, helping to fund the CDMA
network and support it. CDMA was approved in 1993 and allowed for two mode
functionality, where a mobile would default to analog signal when the primary
digital (CDMA) signal was not available. These networks began expanding and
spreading throughout the 1990s. Meanwhile, the uses for mobile devices was
expanding. The Nokia 9000 Communicator, introduced in 1996, had a full QWERTY keyboard and had messaging, calendar, and limited Internet capabilities. It was
the first PDA, though it came at a time when there was still limited data
networking available. Cellular phones essentially shrunk to as small as they
can be by the mid-1990s, and since then have been adding more capabilities like
the Nokia Communicator. The early Blackberry devices only did SMS messaging and e-mail. Satellite mobile phone service was unsuccessful with the Iridium project of 1998, lead by Motorola but going bankrupt after 16 months.
It is interesting to see that mobile phone technologies date
so far back, and just as interesting to see how quickly they evolved from
devices like the Motorola Dyna-Tac to the phones like we have today. I have to
wonder how cell phones would be today if the FCC had allowed for more frequencies
earlier than they did. There are several old commercials on YouTube for early
cell phones and similar, and many are of the “bag phone” variety. I’ve also
seen an old AT&T commercial with a video-capable pay phone, which seems
like an evolution of the first cellular phones as seen in metro areas and
trains as mentioned in Farley’s text. Although we no longer see the built-in car phone as it previously existed, it is possible now for cell phones to connect through the
car’s audio system for a speakerphone effect, allowing for hands-free
conversations. Some are even going so far as to be able to read text and e-mail
messages, and allow the driver to “talk-to-text” to send messages.
My father used to work for Ericsson, and although I was
young I did get to see the evolution of some mobile phones and the technologies
for a time. For example, as phones became slimmer and lighter, and
then as color screens were implemented in phones. I remember as camera phones
were becoming more popular, and a couple phone styles offered an attachable
plug-in camera. Shortly after this, one phone style debuted with built-in
camera phone and Bluetooth capability, and the evolution of cell phone Internet
capability. Now, more and more phones also feature music player functionality,
effectively replacing MP3 players, and we have touch screen phones that eliminate hard keys. The cell phone has practically become a personal accessory and a means of expression for many, and this will only continue as more phone technologies are combined.
