摘要： A communication device (105) includes a first communication block (205) for operation within a first communication network (150); and a second communication block (210) for operation within a second communication network (160). The communication device (105) further includes an audio control (245) for at least one microphone (250). The audio control (245) is coupled to the first communication block (205) for receiving a first audio input for operation of the first communication block (205) and is coupled to the second communication block (210) for receiving a second audio input for operation of the second communication block (210). A low noise ground (315) is isolated from a common ground (320) of the communication device (105) to facilitate the sharing of the at least one microphone (250) between the two communication blocks.

摘要： A technique for activating a transmit mode of a communication device (100) is provided encompassing the steps of generating a light signal on an outer surface of the communication device; inhibiting the light signal; and activating the transmit mode of the communication device in response to the light signal being inhibited. A communication device (100) operating in accordance with this technique includes a light transmitting device (108); and a sensor (110) for sensing light generated by the light transmitting device, the sensor disabling a transmit mode when light is detected and enabling a transmit mode when light is inhibited.

摘要： Methods of enabling late entry into an on-going spread spectrum call are described. A late join frame replaces, and has the same size as, a traffic frame. A late join slot in the late join frame contains sufficient information in preamble and sync subframes to permit a target to join the call. The traffic slots in the late join frame replicate data such that call quality of the call is substantially unaffected if one of the remaining traffic frames is not received. The preamble and sync subframes frequencies may be the same as, or different from, preamble and sync frames frequencies during a call establishment phase of the call. If different, the preamble and sync subframes frequencies are selected from one or more frequencies. Use of the preamble and sync subframes frequencies is compensated for when selecting the traffic slot frequencies to obtain uniform utilization of the spectrum.

摘要： A method for transmitting a communication generated by an originating device to a target device using a repeating device is provided. In the method the communication is transmitted from the originating device and received at the repeating device. A repeater request sequence is transmitted from the originating device and retransmitted from the first repeating device to the target device before the repeater request sequence is received at the first repeating device.

摘要： In a radio transceiver (11) including a voltage controlled oscillator (VCO) (24) having an output for coupling to a switchable load (32, 30), a switch (42) couples a compensating load (44) to the output of the VCO when the switchable load is in an off state. The compensating load has an impedance that compensates for the decoupling of the load impedance from the output of the VCO, thus avoiding frequency pull problems. In a further aspect of the invention a voltage variable capacitor (100) is used as the switch.
