Cracking the code; what is cellular, anyway?
Article Abstract:
Customers of mobile telecommunications services face a confusing array of acronyms and jargon. Cellular phones communicate with a base station, which relays the call to a telephone network and then to the recipient. When the caller moves out of range of a base station the call is automatically shifted to another base station. Cellular phones operate on a narrow part of the radio spectrum, which is allocated by the government in order to provide space for a variety of communications. The majority of mobile services operate at the 800MHz or 900MHz levels, although some new services are operating at the 1,800MHz and 1,900MHz levels because of crowding at the lower frequencies. Lower frequencies tend to travel further and penetrate buildings better, so services operating at the higher frequencies need more base stations and may need to install them in awkward places. Companies must split their assigned frequencies into channels and decide how to send voice communications over these channels.

Nordic track: in Scandinavia, a cellular phone isn't a luxury. It's a necessity
Article Abstract:
Citizens of Scandinavian countries are embracing wireless technology and cellular telephones, and analysts expect the US market will exhibit the same percentage of cellular users within the next five years. Finland, for example, installed the first mobile communications system (GSM) in the world. Nokia and other companies are marketing cellular telephones and services that leverage the convenient communications capabilities supported by the system. Citizens keep their telephones within easy reach and often do not have a traditional installed home telephone. However, people complain that cellular telephone use should be restricted and connections can be garbled or otherwise delayed. Nonetheless, inexpensive cellular rates, the open spaces of Scandinavia, and companies that continue to develop innovative products fuels the demand for cellular technology.

Ionica offers second line for calls. Will many answer? Radio-Wave links provide options to users, but payoffs will take time
Article Abstract:
Wireless communications offer an exciting new alternative to traditional telephone services, but the future of this market is unclear. The new technology requires a transmitter located in the service area, and a small receiver-transmitter on the customer's roof. Digital radio links connect the transmitter to the building's telephone lines. The technology requires a high-frequency bandwidth and there can be no blockages between the transmitting antenna and the receiver's dish. Estimates on the potential growth of the market differ. MTA-EMCI consultants see 60 million customers for wireless local-loop services by 2000, but Northern Business Information sees a smaller global market of 30 million by that time. The largest market will be in developing countries, with the Asia Pacific region accounting for a 40% share.
