摘要:
Embodiments of the invention relate to wireless communications networks, and more specifically to an antenna apparatus for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the PSTN backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network. Known backhaul links include leased lines, microwave links, optical fibre links or radio resources for relaying backhaul traffic between base stations. The fixed line solutions are expensive to implement and maintain, while the radio solutions antenna configurations that are not ideal for relaying data between base stations. In embodiments of the invention, communication between base stations occurs in a first timeslot by use of a first antenna system and communication between a given base station and a user equipment occurs in a second timeslot using a second antenna system. The benefit of this method is that the first antenna system can be optimised for use in communication between base stations, whereas the second antenna system can be optimised for communication with user equipment which preferably occurs within the area of cellular wireless coverage of the sector served by the second antenna system.

A base station including at least a transceiver switch is provided enabling the base station to transmit and receive data in either FDD or TDD mode from an antenna. The base station may be provided with a synthesizer which can be retuned from FDD to TDD mode or alternatively, an FDD and a TDD synthesizer and a switch enabling the transmitter and receiver of the base station to process FDD or TDD mode data respectively.

The invention is directed to a method of communicating between a first transceiver including a plurality of antennas and a second transceiver, the method comprising the steps of: transmitting a signal from the first transceiver to said second transceiver using each of the plurality of antennas of the first transceiver; at the second transceiver, selecting one of the plurality of antennas for use; and communicating between the two transceivers using this selected antenna. The invention is also directed to apparatus and software for performing the methods.

Embodiments of the invention relate to wireless communications networks, and more specifically to method and apparatus relating to wireless backhaul for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the PSTN backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network. Known backhaul links include leased lines, microwave links, optical fibre links or radio resources for relaying backhaul traffic between base stations. The fixed line solutions are expensive to implement and maintain, while the radio solutions suffer from interference from transmissions between base stations with transmissions from user equipment to base stations which are not communicating with other base stations. In embodiments of the invention, the relaying of access data between base stations utilises radio resources other than radio resources used by transmissions from user equipment within an area of contiguous wireless coverage. The benefit of this approach is that it provides a means of avoiding interference between inter-base station transmissions and user equipment to base station transmissions.

摘要:
A multi-facetted antenna array is disclosed for omnidirectional signalling. The multi-facetted antenna array includes a plurality of abutting facets having a planar region under the patch antenna structures, and curving regions between the planar regions and across the abutting edges of the facets. The planar regions under the patch antenna provide proper RF antenna performance, while the curved regions minimize the size of the assembled array. Further disclosed is a method of mounting the associated RF interface module across an inside corner formed by abutting facets. The disclosed multi-facetted antenna array is particularly useful for overcoming the unsightly size and wind loading problems of multi-facetted antenna arrays known in the art.
