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.
PRIORITY CLAIM This application is a Continuation of U.S. patent application Ser. No. 10/033,861 filed on Dec. 27, 2001 �Voice and Data Wireless Communications Network and Method� which is a Continuation of U.S. patent application Ser. No. 09/627,092, filed Jul. 27, 2000, now U.S. Pat. No. 6,404,772 issued Jun. 11, 2002 �Voice and Data Wireless Communications Network and Method�. The entire disclosures of these prior applications, are considered as being part of the disclosure of the accompanying application and are hereby expressly incorporated by reference herein.
FIELD OF INVENTION 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.
BACKGROUND INVENTION 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.
SUMMARY OF THE INVENTION In accordance with the principles of the present invention, a mixed traffic voice and data communications transmitter and network may be provided. The communications network may be a wireless local area network that uses packet based communications. The communications network may include at least one access point that receives voice and other communications for transmission to terminals that are associated with the access point.
DETAILED DESCRIPTION OF THE INVENTION 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.
With reference to FIG. 1, wireless local area network (�LAN�) 20 may include a plurality of cells 22. For brevity and clarity, wireless LAN 20 is illustrated and discussed primarily in the context of a LAN having one cell 22. Cell 22 may include an access point 24 (which is sometimes referred to as a wireless local bridge). Cell 22 may include remote terminals 26. Each terminal 26 may be a mobile, portable, or stationary terminal. Each terminal 26 may be a desktop workstation, laptop computer, palm top computer, handheld personal computer, pen-based computer, personal digital assistant, handheld scanner, data collector, handheld printer, etc. Each terminal 26 may include wireless-network-interface resources that are configured to provide two-way radio or infrared signal communications. Such resources may include an interface card (or an external modem), a software driver, and an antenna. Other suitable resources may also be used, but for clarity and brevity, the wireless network interface resources will be discussed primarily in the context of an interface card, a software driver, and an antenna. The interface card may have been configured to use a standard computer-bus interface (e.g., ISA, PCMCIA, etc.) or standard computer port (e.g., Rs232, RS422, etc.) to provide convenient access to terminal equipment.
