Abstract: The present invention relates generally to a cellular telecommunications network. Each cell has at least one base station for sending messages on a downlink of a Frequency Division Duplex (FDD) to end user equipments within the cell and for receiving messages on an uplink from end user equipments within the cell. Other end user equipment located within the cell which have no or only poor communication directly with the base station over the FDD communicate with the base station indirectly via an intermediate end user equipment, such as a mobile telephone. The intermediate end user equipment includes an FDD transceiver and a Time Division Duplex (TDD) transceiver and an FDD/TDD interface. The intermediate end user equipment receives signals from the base station over the FDD using the FDD transceiver and relays them via the FDD/TDD Interface and the TDD transceiver towards a relevant one of the other end user equipments over a TDD and receives signals from the other end user equipment over the TDD using the TDD transceiver and relays them via the FDD/TDD interface and the FDD transceiver to the base station over the FDD.

Abstract: The present invention allows transmission of multiple signals between masthead electronics and base housing electronics in a base station environment. At least some of the received signals from the multiple antennas are translated to being centered about different center frequencies, such that the translated signals may be combined into a composite signal including each of the received signals. The composite signal is then sent over a single feeder cable to base housing electronics, wherein the received signals are separated and processed by transceiver circuitry. Prior to being provided to the transceiver circuitry, those signals that were translated from being centered about one frequency to another may be retranslated to being centered about the original center frequency.

Abstract: This invention relates to radio communication networks and more particularly, to up-link power control for fixed wireless access communication networks. In accordance with one aspect of the invention there is provided a radio communications uplink power control system wherein distance information between an outstation and a base station and information relating to channel loss is employed by a power control algorithm whereby the signal power transmitted can be optimally controlled. The present invention provides a power control strategy which adapts not only to the total channel loss, but separately to the components of this loss. The total channel loss is calculated from the difference in the received signal power and the transmitted signal power (which is encoded in the message, or sent in addition to the message and therefore known to the receiving station). A method of operation is also disclosed.

Abstract: An antenna arrangement comprising at least 4 upright omnidirectional antenna is disclosed. The omnidirectional antennas are spaced apart in an irregular fashion. By providing at least 4 omnidirectional antenna in a irregular spaced apart arrangement, spatial diversity is provided, at any distant point from the antennas, by at least 3 antennas. Thus the minimum gain, for a four antenna arrangement, approaches 0.75 of the maximum gain when taking relative position of a receiver into account. A method of operating such an omnidirectional antenna scheme is also disclosed

Abstract: The disclosure relates to an asymmetric data access scheme eg Internet access scheme, over a fixed wireless access network. The disclosure provides apparatus for bandwidth efficient provision of asymmetric data services operating a method of communicating between a radio base station and a plurality of subscriber terminals, each subscriber terminal comprising a subscriber antenna. Each sector of a tri-sectored cellular arrangement operates a plurality of frequency division duplex pairs, plus one or more additional unpaired downlink frequencies. On the uplink, packet switched data is transmitted on the conventional access channel, eg ALOHA, but on the downlink, packet switched data is transmitted on an unpaired downlink frequency over a broad sectorized beam.

Abstract: An accelerated access system for a computing device, in which the computing device is connected to a first data network, such as the Internet, via a second data network such as a wireless telecommunication network. The system comprising a server for downloading data from the first data network before that data has been requested by a user of the computing device and a cache for storing the downloaded data. For example, during browsing of the Internet by a user of the computing device the server downloads data linked to an Internet site being displayed by the computing device for storage in the cache. Then when a user subsequently requests the data stored in the cache it appears on the screen of the computing device faster than it would take to access it from the Internet. The system is located between the first data network and the second data network so that not all of the data downloaded by the server and only requests for data made by a user of the computing device are transmitted over the second data network.
