Farley: "Mobile Telephone History"
In Tom Farley’s article “Mobile Telephone History” he documents the history of the development of the mobile telephone from a mere idea that was not yet possible due to a lack of infrastructure to the innovation of the necessary components (the transistor originally designed for calculators) to GSM and CDMA cellular phones. He also documents the “race” for mobile technology and the Federal Communications Commission’s role in restricting the development of American mobile technologies, highlighting the speed at which countries such as Sweden (advancing with less governmental restriction) and Japan (focusing on production and quality control) were able to advance continuing to reiterate how American cellular companies were striving to advance their technology and learning how to compete with countries such as Japan that had much higher standards for quality.
The author begins by defining a mobile telephone as a “wireless device which connects to the public switched telephone network and is offered to the general public by a common carrier or public utility”. He continues to define mobile history “not just [as] a study of the telephone [or] the handset itself, but a look at the wireless system it is connected to”(1). Farley notes that after WWII, the US (although slowly) pushed for the development of mobile technology for three reasons: consumer demand, the existence of research facilities, and manufacturing capability. However, despite these three elements, as Farley documents, the FCC and the United State’s inability to supply the demand of consumers due to limited and simplistic network infrastructure consistently held back the development of mobile technology. Farley explains the early progression of the mobile telephone from the first discussion in 1947 where it was realized that although the components of a mobile telephone existed-a network was needed in order to provide the actual service, the confines of the automobile, the expansion of automatic dialing (removal of the operator), and the “unveiling of the transistor” where the bulky vacuum tubes were now eliminated and mobile telephones could now actually be imagined as “mobile”! The competition between the US and Sweden and Japan to create the first cellular phone expanded as each country. The first commercial cellular radio system did not become operational until 1969 when there could be frequency reuse using a limited number of channels (economy of use) on the metro liner. This year marked the end of the “tube” and although large, telephones were now adapted into briefcase phones, and with the invention of the transistor by Texas Instruments, the rivalry for the first cellular phone began between the two US companies AT&T and Motorola; nevertheless, the FCC delayed their progress. The next pivotal year, according to Farley was 1978 when the AMPS began operating in New Jersey and New York with the help of Oki Electric. Finally this demonstrated that a larger scale mobile telephone cellular system could work, just as was noted in our discussion of the Internet, satellite service for mobile telephones got their start from the military (INMARSAT), which was “originally designed for ships at sea”. MARISAT (the first mobile comm. satellite service began in 1976 but was problematic as there were interruptions between the operator and the user. The major cellular development was in the early 1980s and was outside of the United States, in Mexico and areas around Sweden. In Europe, the continent was swept by analog cellular car phones that used a magnetic stripe (now we have a sim card) yet these phones didn’t operate on the same networks so they were “working towards a digital frame. Later, the NMT450, by far the most advanced up to this point had “600 cells and offered roaming, an important first”. The US was once again still stalled by FCC regulations due to fears of monopolies and service rate. Finally n the mid 80’s when Japan took over part of the NMT, the idea of quality control (Japan) and roaming/networks merged. Furthermore, in the US, the Bell System split apart allowing for competition and new products! In Japan, the NTT ended their monopoly mobile phones but the direction they were going to head was uncertain.
Farley continues to discuss the rise of digital technology and in service called GSM or Groupe Speciale Mobile or what we now call Global System for Mobile Communications. The US wanted a dual system so that they would not have to cut off analog users, Qualcomm is credited with the first prototype for the CDMA telephone; however by the 1990s a digital standard IS-54 was adopted converting any analog channels to digital (numerical representation). GSM offered many things it allowed for privacy, access, and speed, and by “2004 it was announced that GSM had one billion customers” in Europe, Finally in between 1994 and 1997 the FCC “auctioned off blocks of frequencies” and GSM and CDMA spread.
When “the communicator” was released by Nokia, (a precursor to all our slide-out multi function mini personal computers”) I doubt that anyone had any idea what was going to come. The use was not up to par with the definition of a mobile phone as it was not handling voice nearly as well as it handled data (something still problematic with many handheld blackberries etc.). Cingular was the first carrier of UMTS and according to this article “are very expensive”. It is interesting because this article was written in 2005 and the “mobile phones” we use today are far beyond the definition of what Farley defines at the beginning of this article. The expense of a QWERTY keyboard phone with emailing/SMS and GPS capability is not much more than a “standard” telephone and most business people and students use some sort of mini-computer/phone on a daily basis. This article demonstrates how quickly mobile telephones advanced. This is likely due to the existing infrastructure of the telegraph (explained by Kellerman) and also how the development of mobile technology was a global effort.
