Abstract: As demand for data services expands, users expect untethered (“wireless”) systems to provide a same level of service as their tethered (“wired”) systems. Described herein are systems and networks for providing high bandwidth wireless connectivity with user broadcast throughput of at least 1 Mbps. This connectivity is may be used in stationary, portable, and mobile computing environments. A communication system is described having a radio card for electrical communication with a transceiver. A wireless area network is described having a communication system and a wireless local area network adapted for broadcast communication with the communication system. The wireless local area network comprises one converter having a point-to-multipoint radio having at least a 10 MHz bandwidth, and another converter having a point-to-point radio having at least a 10 MHz bandwidth. The wireless local area network may form a cell of a plurality of cells in a wireless metropolitan network.

Abstract: A wireless telecommunication network communicates with a population of subscriber units. A portion of the subscriber units may be programmed to practice a less desirable service configuration, such as a default 13 kb/s vocoding process, even though capable of practicing a more desirable service configuration, such as enhanced variable rate coding (EVRC). Another portion of the subscriber units may not be capable of performing the more desirable service configuration. The network includes a database used to filter the application of a negotiation process during call setup for calls originating at the subscriber units. The negotiation process requests subscriber units to implement the more desirable service configuration. The database is automatically populated through an exchange of messages which occurs during a call setup process for incoming calls to the subscriber units.
