    摘要: An apparatus and method for operating a Multiple Input Multiple Output (MIMO)-capable subscriber node are disclosed. In one embodiment, an apparatus includes a MIMO-capable physical layer transceiver and a Medium Access Control (MAC) layer block that measures a received transmission to determine channel conditions. Upon receiving a transmission wherein said channel conditions meet specified conditions, the MAC layer block transmits a message to an access point indicating that the apparatus wants to switch between a non-MIMO mode and a MIMO mode, and upon receiving an acknowledgement, the MAC layer block switches between the non-MIMO mode and the MIMO mode. An apparatus for operating an access node is also disclosed.

    摘要: An apparatus and method for operating a Multiple Input Multiple Output (MIMO)-capable subscriber node are disclosed. In one embodiment, an apparatus includes a MIMO-capable physical layer transceiver and a Medium Access Control (MAC) layer block that measures a received transmission to determine channel conditions. Upon receiving a transmission wherein said channel conditions meet specified conditions, the MAC layer block requests an access point for permission to switch between a non-MIMO mode and a MIMO mode, and upon receiving permission, the MAC layer block switches between the non-MIMO mode and the MIMO mode. An apparatus for operating an access node is also disclosed.

    摘要: Systems and methods for improving throughput in point-to-point wireless communication links are provided. In one particular implementation, a media access control (MAC) layer of the IEEE 802.11 standard is enhanced for use in point-to-point links to take advantage of the limited number of nodes participating in the link. In one embodiment, a master/slave type protocol provides contention free operation between two wireless nodes. Multiple priority levels and voice traffic may be accommodated with guaranteed Quality of Service.

    摘要: This invention related to a bandwidth estimation method which is easily implementable on network nodes and enables to be made better routing decisions (for example the link with higher residual bandwidth should be favored in routing decisions) and/or estimates the flow admission control (for example accept a new flow only if there is enough available path residual bandwidth) by enabling estimation of availability of the communication capacity estimates.
