摘要： One embodiment of the present invention includes a method for synchronizing packet production and receipt from a digital signal processor (DSP) with polled transmission opportunities in an IEEE 802.11e network. The method comprises producing a packet via the DSP and transmitting the packet from the DSP to a transmission device at a time that is substantially synchronized with a next polled transmission opportunity granted by an access point in an IEEE 802.11(e) network. The method also comprises time stamping the arrival of the packet at the transmission device and transmitting the packet from the transmission device.

摘要： Determining the reasons for packet loss in a wireless local area network; such as an IEEE 802.11 network. The method uses the strength of received signals at a wireless station, such as the received signal strength indicator (RSSI), noise levels (e.g, non-802.11 energy in the 2.4 GHz frequency range), and packet loss information together to determine the network status. In most implementations, the 802.11 implementation (e.g., the 802.11 driver) is responsible for maintaining statistics on the RSSI and the noise whereas the measure of the packet loss is the responsibility of the application. The network status is determined by the endpoint station independent from the access point

摘要： A system and method for transmitting voice data traffic over a wireless medium, such as a voice call using a wireless Internet Protocol mobile phone on a wireless local area network, to increase the quality and the number of voice calls on a Basic Service Set. Endpoints are capable of dynamically switching to alternate voice coding profiles. The WLAN is surveyed by a wireless endpoint to determine whether a congested network condition exists. Coding profiles may be dynamically switched to decrease the congested conditions and improve call quality. If dynamically switching of profiles in not available then the wireless endpoint gracefully degrades the transmission by periodically dropping packets until network congestion reduces and/or call quality increases.

摘要： Providing interoperability on a voice communication network by detecting incompatible bit packing payload formats of ADPCM encoded voice data signals in an encoder/decoder. A mismatch of bit packing formats between little endian format and big endian format is determined through the use of a media gateway control protocol package called Real Time Protocol that allows a Call Agent to detect the presence of garbled audio and allows an intelligent gateway to detect the payload format being used by remote endpoints during call setup procedures and then switch the gateway's encoding for the payload to the payload format being used by the remote endpoint. The invention may be applied to an ITU G.726 encoder/decoder.

摘要： A system and method are provided for improving the throughput of wireless networks, such as IEEE 802.11 networks. Individual devices in the network determine the level of activity on the network. In the event that the network is active, the devices increase throughput by skipping the pending packet transmission and appending its data payload to a future packet transmission. By encoding multiple payloads in a single packet transmission, packet overhead is reduced and MAC layer delays are eliminated. The data payloads are subsequently split back into individual packets for transmission over the wired portion of the network.

摘要： A method for reducing the number of channels that are scanned during a handoff situation for a wireless endpoint station in a wireless local area network (WLAN), such as an IEEE 802.11 network, by tracking past user movements within the WLAN. A suitable sequence of channels to be scanned is generated so that reduce the number of handoffs are reduced and the average time during a handoff is reduced. To reduce handoffs and handoff latencies, the principle of locality (user movement patterns tend to be repetitive) is used. By tracking the past handoffs, future handoffs are predicted.
