Abstract
A wireless Local Area Network provides data service through a data LAN and also provides video broadcast service through a video LAN. A wireless LAN subscriber accesses the video LAN through one of a plurality of Video Access Points (VAPs) that broadcast multiple video programs on a channel having a frequency different than the frequency over which the subscriber accesses the data LAN. Each VAP maintains the video channel in a one-way broadcast-only mode to prevent a wireless LAN subscriber from seeking to uplink information on that channel. In this way, the wireless LAN can employ a common protocol for both data and video transmission, and deliver the video streams at the maximum permissible downlink transmission rate.
