摘要： Disclosed is a method to reduce contention in a networked system and to provide superior bandwidth allocation to network devices contesting for network use. The method achieves reduced contention by reducing the amount of delay a network device is required to wait before attempting to transmit data after a data collision occurred. Superior bandwidth allocation is achieved by placing devices in back-off delay immediately after they transmit successfully.

摘要： Cellular signals or other wireless signals/messages are introduced into a building or to an outside location by transmitting packets corresponding to those signals over a data network and low cost cables to designated locations within the data network. Once the designated packets containing the signals reach the destination, they are then broadcast over the air to a terminal capable of receiving the wireless message. In a first embodiment, an in-building gigabit Ethernet network, such as that currently existing presently in many buildings, is used to distribute radio signals indoors. Instead of transmitting the radio signals over the air from a repeater connected to a base station, coded baseband signals generated by the coding processor (e.g., a CDMA Modem Unit) in the base station are packetized and sent over the Ethernet network to radio processing equipment and antennas distributed throughout the building. The radio processing equipment strips the packet headers from the baseband signal packets so those signals can be broadcast via the antennas to one or more mobile terminals.

摘要： A power control system for a wireless communications system adjusts the transmit power of a wireless transmitter in relation to a number of acknowledgments expected for radio transmissions over a wireless link. For example, a wireless unit monitors the number of acknowledgments it receives (or fails to receive) for radio packets that the wireless unit transmitted over the wireless link. The wireless unit determines the number of acknowledgments lost in relation to the number of acknowledgments expected to be received by the wireless unit. The number of acknowledgments expected by the wireless unit can be based on the number of radio packets transmitted by the wireless unit. If the number of ACKs lost/number of ACKs expected is greater than a first threshold, the wireless unit increases the transmit power level. If the number of ACKs lost/the number of ACKs expected is below a second threshold, the wireless unit decreases the transmit power level.

摘要： In addition to aligning a first unit for proper forward link communications in a wireless environment, there is a method of alignment where a reverse link signal is transmitted from the first unit to a second unit, so that the first unit may be positioned based on at least one signal quality parameter measure contained in a forward link signal reply to the reverse link signal. The method enables an installer to verify signal quality in both the forward link and reverse link directions by reviewing indications of received signal strength for both the reverse link and forward link directions on an LED display, so as to position the first unit for achieving acceptable signal strength in both directions.

摘要： An integrated outdoor radio and directional antenna system provides a direct RF connection(s) on the signal path between a directional antenna and radio components to remove the lossy RF cable(s). Direct connections between the various components of the integrated radio and directional antenna system enable reduced cost and ease of manufacture. In certain embodiments, the integrated directional antenna and radio system provides a direct RF connection between the directional antenna and the radio, and a printed wiring board (PWB) -mounted connector provides a direct digital connection between the radio board(s) and a medium access control (MAC) board. An input/output (I/O) interface provides a digital network interface between the MAC unit and indoor processing circuitry. The digital network interface enables packets of digital information to pass between the indoor processing circuitry and the integrated directional antenna and radio system. An external connection is made between the digital network interface and indoor processing circuitry, such as a personal computer or digital network equipment, but the losses associated with such a digital connection are less significant due to the robustness associated with the processing of digital information in a digital packet data form. In other embodiments, the integrated antenna and radio system provides a direct RF connection between the antenna and RF signal circuitry, such as an RF matrix board which accommodates polar diversity for the antenna and includes a duplexer, RF switching for multiple radios, filtering and any other appropriate RF signal circuitry. A direct RF connection also exists between the RF signal circuitry and the radio components. A direct digital connection is provided between the radio board and the MAC board, and the I/O interface provides a digital network interface with the indoor processing circuitry. In yet other embodiments, all or some of the above components described for the integrated directional antenna and radio system are integrated onto a single printed circuit board and are directly connected together and to the directional antenna.

摘要： Common authentication and authorization (AA) between networks having disparate access technologies may enable a seamless user transition between the networks. A set of AA credentials from a user attempting to gain access to one of the networks may be received, and a subscriber database of another of the networks may be used to verify the set of AA credentials. A communication protocol common to the networks may be used. Additionally, the user may employ a single set of authentication and authorization (AA) credentials, usable over multiple communication protocol layers. Further, a user may perform a single authentication and authorization (AA) operation when roaming across two or more networks by gathering user's key material during an AA challenge and reply session at a data link layer. The gathered material may be used for an AA challenge at an upper network layer or another network as the user transitions between networks.

摘要： A communication system selection algorithm (SSA) implemented by a mobile station chooses between available systems to select a system to serve the mobile station. During initialization, the SSA causes the mobile station to scan the environment and compare available communication systems to determine the best system to provide service. After an initial system is chosen, the SSA causes the mobile station to continuously, or at discrete time intervals, scan the environment for available systems, thus allowing for a seamless switch to an available system whenever a handoff is desired. The SSA chooses the best available system based on measurements of each available system and applying preference rules defined by a service provider and/or user of the mobile station.
