    Abstract: Provided is a method of preventing an unauthorized publication of a media object. On receipt of a user request to prevent an unauthorized publication of a media object, a video link is established with the user. An image of the user is received from the video link and a determination is made whether the image of the user correspond with an image in the media object. Based on said determination an action is performed with regard to the unauthorized publication of the media object.

    Abstract: 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.

    Abstract: 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.

    Abstract: A subscriber device capable of Voice over Internet Protocol (VoIP) communication via a wireless connection with an 802.11 access point to an Internet Protocol (IP) based network includes a codec for encoding a signal into a Real Time Protocol (RTP) packet and a controller for controlling a bit-rate at which the codec encodes the signal. The codec encodes the signal at a first bit-rate during normal transmissions and encodes the signal at a second bit-rate lower than the first bit-rate upon occurrence of a predetermined triggering event.

    Abstract: A method for transmitting voice data traffic over a wireless medium using a decision process for the admission of a voice call, such as a call voice over Internet Protocol (VoIP) over a wireless local area network (WLAN). Admission of the call through the network is based upon the priority level of the call and a congestion level of the WLAN in order to increase the quality and the number of calls on a BSS. Paramters such as codec and packetization periods are selected for the call based upon the priority and congestion level. As the level of congestion in the network Increases, only calls above a certain Priority level are allowed into the network.

    Abstract: 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.
