Techniques for implementing an audio distribution system using only standard network cabling for both power transmission and audio signal transmission. The system comprising of one or more Audio-streaming Source Units and one or more self-contained Network-powered Speaker Units where a plurality of audio streams can exist simultaneously and any audio stream can be directed between any Audio-streaming Source Unit and any Network-powered Speaker Unit.

Common distribution of audio and power signals

A method includes modifying at least one communications protocol packet being passed between at least one of a plurality of portable base stations and a core network, such that the core network considers the plurality of portable base stations as a single base station.

Adaptation of portable base stations into cellular networks

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.

Multi-carrier system selection

Techniques for facilitating a hand-in using proximity-detection and dual-pilot operation detect a presence of a client device in proximity to the network-side device; and transmit a first signal over a first communication channel to the client device, the first signal enabling the client device to access information transmitted in a second signal from the network-side device.

Proximity detection in a network

This description relates to access terminal authorization methods in wireless networks.

Access terminal authorization at private access points in wireless networks

A modem for processing telephone calls includes a line interface for coupling the modem to a telephone line and a computer interface for coupling the modem to a host computer. A processor in the modem between the line interface and the computer interface receives signals running between the telephone line and the host computer. Both the signal processing session and the control processing session required to process the signals are implemented on the single processor.

Modem with integrated control processor and digital signal processor

Apparatus (10) for providing isolation and interconnection between the tip (1) and ring (2) conductors of a telephone line and data communications equipment to be connected thereto, such as a modem or other device (12). The apparatus serves also as a circuit for dialing the telephone, responsive to dialing signals applied thereto. All switching is done electronically, eliminating the need for mechanical relays. A diode bridge (18) is connected to the tip (1) and ring (2) conductors of the telephone line; the active circuitry of the interface derives power through the bridge. A switchable constant-current load (48, 20, 22) is placed across the output nodes of the bridge. The load is switched by an opto-isolator (40) which, in turn, is controlled by the line-seizing switch of the data communications equipment. When the line-seizing switch is closed (i.e., the device is off-hook), the opto-isolator (40) causes the switchable load to place a low impedance d.c. load across the tip and ring conductors while presenting a high a.c. impedance, for drawing the necessary current to seize and hold the line. When the hook switch is open (i.e., the device is on-hook), the load is switched off, presenting a high d.c. impedance as well as a high a.c. impedance. Make-break dialing is accomplished by applying dialing pulses to the same control line (38) as connects to the line-seizing switch.
