A wireless local area network that carries mixed traffic of voice and data communications may be provided. The wireless local area network may include an access point and a plurality of remote terminals that are associated with the access point. The access point may be operably coupled to a wireline network. The access point may receive voice and other communications packets from the remote terminals and the wireline network. Some of the packets may be for transmission to the remote terminals. The access point manages which packets to transmit and when to transmit packets. The access point may manage traffic to maintain a fair distribution of packets and to give priority to voice communications over other communications.

Voice and data wireless communications network and method

A wireless local area network audio and video communication system with mobile units is provided, wherein mobile units are operated in a power saving mode and become active at selected intervals corresponding to the duration of audio and video signals forming audio and video data packets. In a preferred arrangement the mobile units have a digital signal processor that operates at different clock rates during different portions of the intervals.

WLAN communications system

Wlan communications system

A packet data transmission system is disclosed in which remote units, such as remote hand-held data gathering units, which normally communicate with remote base stations via a spread spectrum RF communications, are initialized via spread spectrum RF communications. A network chipping sequence is provided for encoding normal communications and an universal chipping sequence is provided for encoding communications relating to initialization of the remote units. The network chipping sequence is adjustable and must be initialized in each of the remote units to enable normal communications. The universal chipping code is fixed for all remote devices and base stations. Since the universal chipping code is fixed, spread spectrum RF communications of the initialization data, using the universal chipping code, can be effected even if the network chipping sequence is not initially set in the remote units. The initialization data communicated to the remote includes the network chipping code which is then stored in the remote units and used for subsequent normal communications.
