Problems solved by technology

In addition, such information does not generally effect system communications if delivered with some delay.
Currently, the 802.11 standard does not provide specifications for providing voice communications.
Some known wireless LANs carry voice signals as part of the communications traffic but these systems are deficient in effectively meeting such complex communications demands as discussed above.

Embodiment Construction

[0038] The present invention improves mixed traffic voice communications for wireless local area networks (“LANs”) by substantially meeting the communications demands that have been mentioned above. Packets that are to be transmitted in a wireless LAN over a half-duplex communication medium are transmitted in order of priority. Priority may be determined based on at least whether a particular packet is for providing voice communications. One technique for determining whether a packet is for voice communications is to determine whether the intended recipient of the packet has been identified to be voice-capable and further determining whether the packet was received for transmission using a particular communications protocol (e.g., a protocol typically used to send voice communications). Other techniques for prioritizing packets for transmission and for determining which packets are for voice communications are discussed below.

Abstract

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.

Description

BACKGROUND [0001] This invention relates to wireless local area networks (“LANs”), and more particularly, to wireless local area networks that carry a mixed traffic of voice and data. [0002] Wireless LANs are typically used in applications that involve mobile computers, in applications where wireline installation is not feasible, etc. Such applications include warehouse inventory tracking, portable point of sale, shipping and receiving, package tracking, etc. [0003] The IEEE 802.11 communications standard has been used by some vendors to provide interoperability between wireless LAN equipment. The 802.11 standard specifies a protocol in which information is transmitted in packets. The standard specifies features such as packet size, packet content information, data rates, roaming, etc. The primary type of information that was initially transmitted in systems that were designed to the 802.11 standard as published was information such as barcode information, point of sale information,...
