Farley--"Mobile Phones"
In this text, Tom Farley describes the history of cellular phones. A
cell phone, Farley states, is "a mobile telephone [that] is a wireless
device which connects to the public switched telephone network and is
offered to thegeneral public by a common carrier or public utility". Farley says that 'public mobile' telephony began in the mid-19 th century post-World War II, but notes that some "primitive
mobile telephones existed before the War", which were more like two-way
radios. The U.S. was able to begin developing cellular devices soon
after WW II unlike much of the rest of the westernized world, which was
in ruins from war. The first "true cellular radio system formobile
telephony" took place in December of 1947 in Bell Telephone
Laboratories. In July of the following year, Bell Labs made public its
revolutionary invention of the transistor, which brought all
electronics into a fundamentally modern era. Large mobile devices were
being released by the late 1950s. In 1958 Jack Kilby of Texas Instruments created the integrated circuit. Kilby
created a complex circuit from a single piece of germanium. The idea of
cellular radio was widespread amongst telecommunications companies by
the end of the 1960s.
Bell Systems released the cellular radio publicly in January 1969. Passengers aboard the Metroliner
train could make paid calls while the train was in motion, detached
from any wires. Farley states that, "the first cell phone was a
payphone" versus a mobile device for private use. Motorola had a patent
filed for a cellular radio in 1973. Motorola's market mainly focused on
dispatch radios for taxis and public safety officers. The first
commercial cell phone system of its kind was released by The Bahrain
TelephoneCompany in 1978. INSMARSAT began in 1979 and focused
on telephony via satellite, but later connected their network to land
and aircraft equipment. New services were released by Bell Laboratories
and other companies after the government split American Telephone and
Telegraph apart.Throughout the 1980s, wireless infrastructure with a higher call volume capacity
was developed. By 1990, the cell phone network of North America began
to use IS-54, a "formally adopted digital standard" which "worked with
existing AMPS systems". The first texting device was released by Nokia
in 1996. During the 1990s cell phones became "as small as practically
possible" because "the keypad and display limited any more reduction in
size". By the year 2000, Sharp released the "first integrated camera
phone".
Farley states in his article that by 2005, the number of
cell phone users would hit 2 billion. I found on the United Nations
website that an estimated 4 billion people were using cell phones by
2008. A technology which took half a century just to gain a few million
users doubled from 2 billion to 4 billion in only 3 years! The first
cell phones I remember were the in-car units that were awkwardly tied
into a car's stereo system. They never seemed to work well and users
went into roam after just an hour or so of driving. My Dad purchased a
"bag phone" like the one shown on page 30 when I was in elementary
school. It had a clumsy magnetic antenna that had to be placed on top
of the car to work--if it even worked at all. Now we consider phones
"clumsy" when they have a half inch antenna protruding from them. It is
amazing to see how much cell phones have changed in the past 10 years.
It is also amazing to see where they are headed in the future.
