Abstract: The present invention provides a Wireless Local Area Network (WLAN) terminal, having a wireless interface that exchanges packetized communications with servicing Access Points (APs). A processing unit communicatively coupled to the wireless interface selects an appropriate programmable COder/DECoder (CODEC) with which to convert incoming packetized communications to incoming user communications, and outgoing user communications to outgoing packetized communications. A user interface coupled to the programmable CODEC receives the incoming user communications and produces the outgoing user communications. The processing unit monitors the serviced packetized communications to determine a communication quality level delivered by the wireless interface. Then the processing unit chooses the selected coding scheme based upon the communication quality level.

Abstract: Dynamic real-time quality management of packetized communications in a network environment. Packetized communications are monitored by and exchanged between wireless Access Points (APs) and wireless terminals or by quality monitoring modules located within network segments or at network vertices. The processing unit analyzes the packetized communications to identify communication signatures associated with the packetized communications. The processor then uses these signatures to identify network impediments to the exchange of the packetized communications. These impediments may take the form of coding problems in which case an appropriate coding scheme is employed by the programmable COder/DECoder (CODEC) to convert incoming packetized communications to incoming user communications, and outgoing user communications to outgoing packetized communications. These impediments may also take the form of communication problems along and between the various network segments.

Abstract: A system and method with which to establish parallel communications between the wireless terminal and the PSTN via a WLAN and an alternative network such as cellular or satellite networks. Once the parallel communications are established, handoff criteria govern seamlessly switching communications between the WLAN and the alternative network in order to avoid any lost or dropped communications. Communications may be serviced between a Private Branch Exchange (PBX) and a wireless terminal. The PBX communicatively couples to a wireless local area network (WLAN). Calls received at the PBX for the wireless terminal are routed to the wireless terminal if the wireless terminal is serviced by the WLAN, otherwise an attempt is made to deliver the call via an alternative network. Should both deliveries fail, the call is delivered to an alternative destination such as voice mail or an operator.
