摘要： A stabilized ultra-high bandwidth capacity transceiver system that combines an E-band (71-76 GHz, 81-86 GHz) millimeter wave RF transceiver with an eye-safe adaptive optics Free Space Optical (FSO) transceiver as a combined apparatus for simultaneous point-to-point commercial communications. The apparatus has a high degree of assured carrier availability under stressing environmental conditions. The apparatus establishes and maintains pointing and stabilization of mmW RF and FSO optical beams between adjacent line of sight apparatuses. The apparatus can rapidly acquire and reacquire the FSO optical carrier link in the event the optical carrier link is impaired due to adverse weather.

摘要： An access point coupled to an Ethernet port detects whether it is using power over Ethernet, and if so, adjusts its operation to maintain its power requirements within those capable of being supplied by power over Ethernet. The access point might include a detector capable of determining if external power is available, or if that access point is operating using power over Ethernet. If the access point is operating using power over Ethernet, it adjusts the operation of its radios, gracefully degrading those radios from (first) both radios operating in 3x3 mode, to (second) a first radio operating in 3x3 mode and a second radio operating in 2x2 mode, to (third) both radios operating in 2x2 mode. The power adaptation circuit may also throttle clock speeds in the system (processor or peripherals), or shut down or idle various peripherals to lower power consumption for the duration consumption is high.

摘要： An access point housing structure includes a first enclosure, a second enclosure to house an array of antenna patches, and an omni-directional hinge component. The first enclosure includes a first coupling mechanism located near one of the corners of the first enclosure. The second enclosure includes a second coupling mechanism located near a corner corresponding to the location of the first coupling mechanism. The omni-directional hinge component connects to the first coupling mechanism and to the second coupling mechanism and allows rotation of the second enclosure about a first axis along an edge of the first enclosure adjacent to the first coupling mechanism and about a second axis along an edge of the second enclosure adjacent to the second coupling mechanism.

摘要： A method for allocating resources of a shared medium in a large distributed network. The nodes make reservation requests in parallel during a series of reservation time slots. For each slot, one node of a pair transmits a request and the other listens. A node transmits its own requests and the requests of nodes from the request it received. The process repeats until all nodes have transmitted their requests for medium access, wherein one node knows the medium access requests of all the nodes in the network. In this fashion, 1024 nodes can make their requests in ten time slots. The last node may be a master node or may transmit to a master node or base station, which transmits a full or partial grant. Alternatively, the nodes may simultaneously transmit their requests to a master node, which passes the groups requests to a master node nearer the base station.
摘要翻译：一种用于在大型分布式网络中分配共享介质的资源的方法。节点在一系列预留时隙内并行进行预约请求。对于每个时隙，一对节点发送一个请求，另一个节点侦听。节点从接收到的请求中发送自己的请求和节点的请求。该过程重复，直到所有节点已经发送他们的媒体访问请求，其中一个节点知道网络中所有节点的媒体访问请求。以这种方式，1024个节点可以在十个时隙中进行请求。最后一个节点可以是主节点，也可以发送到主节点或基站，主节点或基站发送全部或部分授权。或者，节点可以同时将它们的请求发送到主节点，主节点将组请求传递给靠近基站的主节点。

摘要： A system and method for wireless broadband transmission in a scattering environment using a network of coherent repeaters. In one embodiment, the system comprises a number of groups of nodes. The nodes in a group are capable of broadcasting to each other and of beamforming to another group of nodes. A basestation broadcasts a number of signals at the same frequency and time. Each signal comprises a desired signal and multiple interference signals. The signals arrive at the nodes as co-channel interferers. The nodes are able to distinguish between the signals sent from each antenna of the basestation. Each of the nodes is further operable to transmit a repeated signal to a destination node such that the repeated signals collectively cancel out co-channel interference at the destination node. Therefore, the destination node receives a signal substantially free of co-channel interference.
