  • Publication number: 20140133368
    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. 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 and sends signals to/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.

  • Patent number: 8688172
    Abstract: The present disclosure 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.

  • Patent number: 7418269
    Abstract: A wireless communications system has a plurality of uplink and downlink channels available for use. Channels are distributed among different operators who may plan their networks in a non-ideal manner. A terminal uses an uplink channel and a downlink channel selected from those available and performs a method to check whether it is causing interference to other users of the system. The method determines whether the terminal is transmitting at a power which may cause interference to an adjacent uplink channel. If so, the terminal determines which downlink channel is associated with the adjacent uplink channel and monitors that downlink channel. The terminal may then operate in a manner which will reduce interference.

  • Patent number: 6791952
    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.

  • Patent number: 6591288
    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.

  • Patent number: 6501964
    Abstract: The invention relates to sub macro cellular layers of a wireless communications system. An object of wireless communications system design is to reduce the number of base station sites required by increasing their range and or capacity. The term, “capacity” is used herein to refer to any suitable measure which provides an indication of how many conventional mobile terminals or other terminals are able to communicate effectively with a given antenna arrangement. Macro base station sites for cellular systems are particularly expensive, both in terms of the equipment required and the need for a geographical site for each cell site where, inter alia, large structures are frequently employed where planning permission is required. The present invention seeks to provide a system and method for reducing the effects of adjacent channel interference, especially in 3G CDMA base stations.

  • Patent number: 6275486
    Abstract: This invention relates to radio communication networks and more particularly, but not exclusively, to radio communication networks using multiple access techniques. A system and method for adaptively changing the characteristics of a signal transmitted across a network is provided. In one embodiment, the communications network comprises at least two stations for transmitting and receiving; wherein at least one of the stations is capable of sending a control signal to the other station after receiving a signal transmitted over the network from the other station after analysis of the transmitted signal, which control signal is transmitted as a data packet independent of the other data and overhead signals.

  • Publication number: 20010012780
    Abstract: The invention relates to a fixed wireless access telecommunications system wherein there is provided a multi tier, preferably two tier, frequency plan in which a number of frequency plans, preferably two frequency plans are overlaid. Thus, a first frequency plan can be implemented using first sets of antenna elements and additional overlaid frequency plans can be implemented using additional sets of antenna elements which may be co-located at the base stations with the first sets of antenna elements. The frequency plans may be sectored with the base station comprising at least one directional antenna. The first and second frequency plans are generally the have the same topology except that the first frequency plan is rotated relative to the second.
