    摘要: A terminal for communicating with a communication satellite A terminal comprising: a first transceiver for communicating with at least one device in a short range network; a second transceiver for communicating with a geostationary communication satellite in a network deploying a plurality of forward channels for the communication satellite to transmit data to said terminal and a plurality of return channels for the terminal to transmit data to said communication satellite, the second transceiver being configured to transmit data from said at least one device in one of said plurality of return channels. The at least one device may comprise a plurality of utility meters and other sensors. A large system comprising a plurality of the terminals, a communication satellite and a data authority may provide a system for collecting utility meter readings across a geographical region.

    摘要: A method of processing a multicast frame in a wireless local area network (WLAN) and an appartus supporting the method are provided. The method comprises receiving, at a station, a unicast frame from an access point (AP), the unicast frame including an unicast address indicating a single station which receives the unicast frame, receiving a multicast frame from the AP, the multicast frame including a group address indicating a group of stations which receives the multicast frame, determining whether the unicast frame is duplicated with the multicast frame, and discarding the multicast frame if the unicast frame is duplicated with the multicast frame.

    摘要: Methods, radioterminals, and broadcast message generation consoles provide location-based broadcast messaging for users. A method of operating a radioterminal can include receiving at the radioterminal over a wireless air interface a broadcast message that includes region information that defines a geographic region of applicability. A determination is made at the radioterminal whether the radioterminal is located in the region of applicability. A functional mode of the radioterminal is activated in response to the radioterminal being in the region of applicability. The functional mode may include activating a user interface of the radioterminal.
