The present invention utilizes adaptive antenna arrays at a base station to increase the forward link capacity of mobile data systems. One or more simultaneous forward link beams are formed and are switched (or hopped) in a time division manner among subscribers. The beam hopping sequence is randomized by varying the time slot and/or carrier frequency of each subscriber. In space-time hopping, the position within a frame of the time slot for each subscriber is varied in a pseudo random sequence. In space-frequency hopping, the carrier frequency for each frame is varied in a pseudo random sequence. The pseudo random beam hopping sequence provides a gain due to interference diversity in addition to the antenna array gain. Forward link beam forming algorithms use space-time or space-frequency hopping to increase the capacity of mobile data systems.

The present invention relates to wireless communications, and in particular although not exclusively, to networks of indoor collocated or overlapping wireless coverage areas especially those intended for operation in unlicensed spectrum such as the Industrial Scientific and Medical (ISM) bands. The present invention provides a method of controlling the transmission power associated with an air interface channel, the method comprising determining a quality of service measure for a signal to be transmitted on a second air interference channel; determining an interference measure corresponding to the interference on said second air interface channel which will be caused by transmissions on said first air interface channel; requesting the changing of the transmission power associated with the first air interface channel when the signal is to be transmitted on the second air interface channel, when the quality of service measure is above a predetermined value and when the interference measure is above a predetermined value for said quality of service value.

A node for satellite system communications between a ground station and a satellite includes a fiber optic bus on the satellite. An optical drop is coupled to the bus. The optical drop resolves an optical signal destined to the given satellite from the optical bus. An uplink and downlink receive and transmit communications from a ground terminal. A router is coupled to the optical drop and the uplink and downlink. An address reader and a table are used by the router to determine the destination of the received RF signals. The received RF signals are converted to optical signals by an optical source. The optical source has a wavelength that corresponds with the destination satellite. The optical signals are transmitted to an adjacent satellite by an optical transmitter such as a transmitting telescope.

Systems and methods for wireless networks with inner and outer cells are provided. A base station determines an amount of traffic on an inner and outer cell. When the traffic exceed a predetermined threshold value, traffic is adjusted on the inner or outer cell. Traffic can be adjusted by handing off some of the traffic from the inner cell to the outer cell, from the outer cell to the inner cell, between sectors of the inner or outer cells and/or by handing off traffic to a proximately located base station.

The retention member may be adapted to maintain coupling of the first plate and the second plate after breakage of the frangible connection.

A technique for delivering communications services to a large number of users employing relatively inexpensive, widely available handsets. More particularly, the technique utilizes a network apparatus that supports individual access to a community of users and supports access to a wireless communications system (e.g., any well-known Code Division Multiple Access (CDMA) wireless network). That is, the communications hub functions similar to a communications switch with a number users employing inexpensive handsets (e.g., well-known 900 MHz cordless telephones) on one side and the functionality of a mobile terminal, and CDMA interconnection, on the other side. Therefore, the users (i.e., subscribers) employ relatively inexpensive, widely available handsets, in conjunction with the network apparatus, to access a wireless communications network and the associated communications services offered from the wireless service provider.

The present invention relates to a method for reducing interference in a cellular radio communication network, said network comprising a plurality of base stations and a plurality of terminals to be scheduled on frequency and/or time resources.

According to the present invention, the method comprises the steps of:

• • determining interference parameters from at least two base stations;
  • reporting said interference parameters from said at least two base stations to an interference coordinator;
  • determining at said interference coordinator resources to be allocated to said plurality of terminals minimising an overall interference criterion;
  • reporting from said interference coordinator to said at least two base stations the resource allocated to the different terminals.

The present invention relates to a method and apparatus for controlling a connection transfer in a cellular network having at least two systems, such as a GSM system and a WCDMA system. Based on a load determination, a service-based inter-system or inter-frequency handover of the connection to another system or to another carrier of the same system is initiated if the determined is below a threshold and service priorities are indicating it. If it exceeds the threshold, an additional load-based inter-system or inter-frequency handover can be initiated. If the load of the target cell is not known, a load estimation based on a learning process can be used to derive a probability of success of an interfrequency or inter-system handover, which may be used for deciding on the initiation of the inter-system handover. The learning process may be performed by evaluating preceding interfrequency or inter-system handovers to the target cell or preceding interfrequency or inter-system handovers from the target cell. Thereby, users can be shared between different radio access technologies or systems or between different carriers of one system to thereby improve network capacity and quality of service for both systems and carriers. Furthermore, unnecessary inter-system handovers can be prevented in case the load of the target cell of the other system is not known.

The communications compartment may be located proximate a top of the PCS, and may at least partially enclose a communications subsystem. The display compartment may be disposed along an upper portion of the PCS, and may at least partially enclose a display subsystem. Access to the interior of a compartment may be provided to authorized users without providing access to interiors of other independently accessible compartments.

A method and system for sharing over-allocated bandwidth between different classes of service in a wireless network. Traffic is transmitted for a first service class in excess of bandwidth allocated to the first service class using unused bandwidth allocated to a second class. After transmitting traffic for the first service class in excess of bandwidth allocated to the first service class using unused bandwidth allocated to a second class, traffic for a third service class is transmitted in unused bandwidth remaining in the second service class.

A symmetrical capacity network may be adapted to accommodate asymmetrical network traffic patterns by deploying Protected Dedicated Wavelengths (PDWs) between one or more head-end nodes and the access nodes on a ring-based topology network. The PDWs include pairs of wavelengths extending in opposite directions around the fibers forming the original ring and terminating at the intended access node. The pairs of wavelengths form unidirectional working and protection paths from the head-end node to the intended access nodes. By deploying the symmetric capacity and asymmetric capacity on the same platform within the head-end node, it is possible to apply policy across the network resources to allow traffic flows to be selectively placed on the most appropriate network resource.
