 An Investigation of the Safety Implications of Wireless Communications in Vehicles DOT TOC
While voice communication has been the primary focus of the cellular industry, recent technological and societal trendsandemdash;in mobile communications and computer hardware and software (e.g., size, flexibility, connectivity), and the desire to "work on-the-road" have resulted in a move towards integration of technologies.
The conclusion appears reasonably plausible, particularly in light of the trends in the data, the growing complexity of the technology, and the inherent distraction potential of using such devices from a moving vehicle.
Consumers might be given information on cellular telephone design features that may make them easier or harder to use.

The Federal Communications Commission in early August decided that cellular carriers would no longer be required to keep open a few analog channels for the now small number of non-digital phones.
Operating details foreshadowed analog cellular routines, the complexity of which we will see soon enough.
Different cellular radio systems use frequency division multiplexing (analog), time division multiplexing (TDMA), and spread spectrum (CDMA) techniques.

 OET --Human Exposure To Radiofrequency Fields From Cellular and PCS Radio Transmitters
Typically, for a cellular base station, a maximum of 21 channels per sector (depending on the system) could be used.
Measurements and computational analysis of SAR in models of the human head and other studies of SAR distribution using hand-held cellular and PCS phones have shown that, in general, the 1.6 W/kg limit is unlikely to be exceeded under normal conditions of use.
In recent years publicity, speculation and concern over claims of possible health effects due to RF fields from hand-held wireless telephones prompted industry-sponsored groups, such as Wireless Technology Research, L.L.C. (WTR) and Motorola, Inc., to initiate research programs aimed at investigating whether there is any risk to users of these devices.

However, in a portable environment the last 4 digits or the 7-digit telephone number may not always reside in the central office exchange to which the NXX was natively assigned.
The database query is performed for all calls where the NPA-NXX of the called number has been marked in the switch as portable.
Cellular, broadband PCS, and covered SMR providers are required to have the capability to query the number portability databases nationwide, or arrange with other carriers to perform the queries, by December 31, 1998, in order to route calls from wireless customers to customers who have ported their numbers.

See the table on the right for a comprehensive listing.
Professional mobile radio systems are very similar to cellphone systems and attempts have even been made to use TETRA, the international digital PMR standard, to implement public mobile networks, but normally PMR systems are sufficiently separate from the phone network to not really be considered phones but rather radios.
Most current cellphones use a combination of radio wave transmission and conventional telephone circuit switching, though packet switching is already in use for some parts of the cellphone network, especially for services such as Internet access and WAP.

 Overview of the Global System for Mobile Communications
GSM is a digital system, so speech which is inherently analog, has to be digitized.
Minimizing co-channel interference is a goal in any cellular system, since it allows better service for a given cell size, or the use of smaller cells, thus increasing the overall capacity of the system.
The developers of GSM chose an unproven (at the time) digital system, as opposed to the then-standard analog cellular systems like AMPS in the United States and TACS in the United Kingdom.
