ses. Second, it will benefit commercial vendors and service providers if their customers enter the high-speed wireless world as consumers, not just as employees. Third, the largest firms have the option of developing their own wireless infrastructure on a private band. At high volume, this can be cost-effective compared with leasing time on the cellular net- work. Doubtless some major companies will develop systems in-house and maintain control of them, whereas others will choose to outsource and rely on cellular data ser- vices. Some companies will create systems that rely on both, perhaps using their own network in their home cities and leasing wireless service elsewhere so that they get op- timal cost performance in each region. Eventually, government and not-for-profit agen- cies will begin to use these services as well. A variety of services will be provided. Beyond Internet access and access to organi- zational networks, we also can foresee the possibility that wireless networks will com- pete to provide a variety of specialized functions, especially if data capacity increases and costs come down. One possibility is that wireless networks will provide a lower-cost alternative to private radio networks. Some smaller police forces are already relying on cell phones rather than radio systems, although, of course, encryption technology will have to provide very strong security for such a service to grow in that field. Many industries, such as gas and electric utility companies, taxicab services, and livery services, already use private networks to carry wireless data. Demand is grow- ing for increased data capacity as these customers are looking to provide real-time mapping information and other data-intensive functions. It is possible that the cellular networks will be able to compete to provide these services. In this arena, cellular has an advantage over satellite transmission, which has a very slow bit rate from the re- mote terminal back to the PSTN, as low as 8000 bits per second. 11 The general trend in
