Abstract: A wireless communication system (20) includes a base station (22) that is capable of communicating with a plurality of mobile stations (24). The base station includes a modular device (50) that allows flexibility in locating the various operative electronic components (52, 54, 56, 58) of the base station. Disclosed examples include a radio frequency head module (55) that packages components traditionally associated and located with a radio in a manner that allows them to be located with the Tx and Rx portions of the radio or at a remote location. One example includes a radio frequency coupling for communications between the radio (54) and the radio frequency head module (55). Other examples include intermediate frequency couplings (70, 74).

Abstract: A wireless communication system (20) includes a base station (22) and remotely located radio frequency units (30, 32). A passive antenna arrangement (60) associated with each radio frequency unit conveniently and economically provides radio frequency coverage within otherwise difficult-to-reach areas. Disclosed examples include radio frequency units at various locations within a building (50) that is effectively divided into sectors served by the base station.

Abstract: A wireless communication system (20) utilizes a first frequency from a bandwidth provided by a base station (24) for communications between the base station (24) and mobile stations (26, 28) using at least one intermediary transceiver (42-52). The intermediary transceivers receive communications from at least one of the mobile stations (26, 28) or the base station (24) on the first frequency and transmit that communication on the first frequency. The intermediary transceivers (42-52) also transmit a corresponding relaying communication on a second frequency from the bandwidth provided by the base station (24). In this example, the second frequency along with other frequencies from the base station bandwidth provides wireless backhaul for communications between the intermediary transceivers, which are strategically located to extend coverage within a desired area, such as the interior of a building.

Abstract: A base transceiver station includes at least one base band unit and at least one radio frequency unit. The base transceiver station also includes a wireless link for coupling the baseband unit with the radio frequency unit. The baseband and radio frequency units may be spaced, in one example, at a distance of about 500 meters. In support of the wireless link, the base band unit(s) may comprise a multi-headed air interface antenna (e.g., one or more antenna heads per sector). The multi-headed air interface antenna may be tuned to support a data rate of at least 100 Mbps, and may comprise wideband and/or narrowband characteristics. Moreover, the radio frequency unit(s) may comprises an RF antenna for supporting the wireless link. The RF antenna may be tuned to support a data rate of at least 100 Mbps and also may comprise wideband and/or narrowband characteristics.

Abstract: A wireless communication system (20) includes a base station controller (22) that receives timing information from a data set (26) that is generated by a neural network (28). The data set (26) allows for generating timing information based upon previous time information received from a GPS (24) and in one example, is capable of covering a time interval of up to two weeks during which effective communication with the GPS may be interrupted. In one example, the data set is continuously updated so that the base station controller (24) continuously has up to two weeks of future time information available.
