    摘要: An antenna steering algorithm for a smart antenna uses signal quality metrics and link quality metrics for selecting a preferred antenna beam. The link quality metrics supplement the signal quality metrics for improving the antenna steering decision. The link quality metrics are based on information available from existing counters operating in the media access control (MAC) layer. Separate estimates of the frame error rates in the receive links and in the transmit links are obtained. One estimate is the downlink quality metric (DLQM) and another estimate is the uplink quality metric (ULQM). Alternative link quality metrics are based on throughput and data rates of the exchanged data.

    摘要: A system and method for communicating between a plurality of remote transceivers and a network is discussed including multiple types of serially-connected communication links, upon which data flows are established to communicate information between the remote transceivers and network. A hub is coupled to one end of a hardwired communication link while an access unit is coupled to the other end. In addition to supporting communications on the hardwired link, the hub supports communication with the plurality of remote transceivers over a wireless link of a first type. The access unit at the other end of the hardwired link is in further communication with a base station over a wireless communication link of a second type, while the base station is in further communication with the network. Based on this topology, data flows over this string of interconnected communication media support information transfers between the plurality of remote transceivers and the network.

    摘要: A technique for communicating with a local area network (LAN) via a wireless connection determines whether a first short-range, high-speed, wireless communication path is available and connects to the LAN using a longer range, lower speed wireless communication path if the short-range, high-speed wireless communication path is not available. The low-range, high-speed wireless communication path is a wireless LAN connection such as an IEEE 802.11-compliant wireless LAN and the long-range, low-speed wireless communication mode is a cellular CDMA-type connection. Determining whether the first IEEE 802.11 mode is available can be done by detecting a beacon signal, or by transmitting a probe request message and detecting a probe response message in response to the probe request, indicating the presence or availability of the short-range, high-speed wireless communication path. Alternatively, the availability of short-range, high-speed wireless communication path can be detected by simply detecting activity on it.
