Abstract: Among other things, a communication system comprising remote units, a reference timing source, a controller, a controller clock, and a remote unit clock. The remote units exchange radio frequency (RF) signals with mobile devices. The reference timing source is synchronized with a coordinated universal time (UTC) or a Global Positioning System (GPS). The controller clock is synchronized with the reference timing source and provides timing information to the controller. The remote unit clock is synchronized with the controller clock and provides timing information to a remote unit. The controller and the remote unit are configured to transmit time stamp messages to synchronize the controller clock and the remote unit clock, by avoiding contention between time stamp transmissions and baseband data transmissions or between time stamp transmissions of different remote units to the controller.

Abstract: In general, a method performed on a personal base station includes transmitting a first pilot signal to a portable access terminal operating in an idle mode in a macrocell that uses a first carrier frequency. The first pilot signal is transmitted in the first carrier frequency to allow the portable access terminal to temporarily connect to the first pilot signal. A second pilot signal is transmitted in a second frequency that is different than the first frequency. The portable access terminal is dispelled from the first pilot signal, and the portable access terminal is allowed to connect to the second pilot signal.

Abstract: A method includes receiving from a server, information that is based on an offset between a boundary of a synchronous capsule in a control channel cycle occurring at an access point and a boundary of a periodic pseudo-noise sequence, and synchronizing an access point to an absolute time based on the information. In addition, the method includes transmitting to the server a difference between a first boundary of a PN short code of a current sector and a second boundary of a PN short code of a reference sector.

Abstract: A transmitter is provided having transmission methods that minimize the power needed to ensure reliable reception in a coverage area. In one aspect, data that requires re-transmission as acknowledged mode data is re-transmitted when the power level of the transmission link is higher than a pre-determined level set for reliable reception. The data rate of the re-transmitted data is set according to the difference in the actual power and the pre-determined level. In a second aspect, two transmitting antennae are used to transmit the same signals with a frequency off-set. The frequency off-set can be used to determine the phase of the signals being received at the receiver, so that a phase off-set can be introduced to optimise the effect of interference at the receiver.

Abstract: A proxy is in communication with an internet protocol network and a mobile operator network. The proxy receives first communications from access points via the internet protocol network, transmits content from the first communications to the mobile operator network, receives second communications from the mobile operator network, and transmits content from the second communications to the access points via the internet protocol network. The proxy may perform operations based on the first and second communications received from either the access points, or from the mobile operator network. The operations performed by the proxy may include modifying the communications, saving certain information regarding the communications, performing authentication, encryption, or decryption of the communications, determining a destination for the communications, or sending the communications to a destination.

Abstract: The invention relates to a method and system of setting transmitter power levels, particularly in a Local Network Node transmitter, providing a pico cell for private use. A User Equipment (UE) is used to make measurements of the transmission link properties, such as downlink power and round trip time. Based on the measurements made at one or a plurality of locations, the power of the Local Network Node can be determined such that interference is minimized with any overlying cells of a macro-network. Call handovers between the UE and the cell of a macro network can also be arranged based on properties measure by the UE.
