PERFORMANCE ANALYSIS AND SPECIAL ISSUES OF WIRELESS BROADBAND SYSTEMS IN THE INFORMATION AND COMMUNICATION ENVIRONMENT

摘要

Wireless broadband Internet access uses many frequency bands. Wireless broadband modems offer similar performance to cable modems operating over wired cable television systems (CATV), but the business is easier to enter as the transmitters cover an entire city or region. A broadband wireless system can deliver up to 30-Mbps data capacity in a 6-MHz channel. The wireless system's strength is that it can quickly provide high burst speed Internet access to a 10-mile, 20-mile, or 35-mile radius depending on the frequency band used. This allows the service provider to work with or compete with CATV to serve small-sized and medium-sized business and high-end users. The CATV coaxial-cable plant typically services residential neighborhoods and may not serve these premium customers. Wireless imposes special requirements on the technology and business relationships.
