摘要： The present invention offers significant improvements in the performance of a radio receiver operating in an environment with high desired band interference. The present invention comprises a high selectivity RF circuit that is located between the antenna and the radio receiver, and utilizes superheterodyne technology to filter adjacent channel interference in the desired band frequency spectrum. This type of interference is problematic for IEEE 802.11 radio receivers that are implemented with the popular direct conversion radio receiver architectures. The present invention may be utilized in many types of radio receivers.The high selectivity RF circuit comprises channel select filters, a down-converter, an up-converter and a programmable local oscillator. The radio receiver provides control signals to the high selectivity RF circuit that permits the selection of an appropriate channel select filter and permits the generation of a local oscillator that subsequently generates the proper intermediate frequency in a mixer.

摘要： A communication system comprising one or more wireless stations programmed to await for an authorizing signal to initiate wireless communications with a network controller or access point. The network controller maintains identification information in different queues, said queues based upon the wireless station's activity. The wireless station identification information is moved between the different queues in response to wireless station activity. Between polling, each mobile station aggregates data for the next opportunity to transmit. Multi-polling may be employed such that more than a single station is polled at a time. Polling is accomplished by polling one of the more active station along with a less active station. The less active station is unlikely to transmit, so collisions are avoided to a certain degree. If a lesser active station becomes active, it is moved into the more active queue and consequently will be polled more often.

摘要： Methods and systems for exploiting orthogonal antenna polarizations which restore MIMO capability to an otherwise single path link are disclosed. Disclosed multi-polarization antennae and antennae arrays create two orthogonally polarized independent channels of communication which are transmitted and received by similar multi-polarization antennae, taking advantage of the fact that orthogonally polarized electromagnetic waves travel independently and can be used as independent communication channels. Transmitters; and receivers comprising such multi-polarization antennae behave as if two independent communication channels are available in the same line-of-sight link, allowing a doubling of the bandwidth and providing a way to exploit MIMO in outdoor and other line-of-sight communication links.
