Abstract: A system and method providing a frame structure to received channel data sent over an air interface of a wireless communication system. The system and method may allow compensation for transmitting and receiving frequency variations, synchronization at the receiver, and provides a virtual signaling channel which may be used for system alarms and status. In one embodiment, the system uses bit stuffing, a frame preamble and a signaling preamble to transmit data at a high data rate in the ISM band.

Abstract: The present invention provides an apparatus and method for free space optical communication. The apparatus and method provide a free-space optical communication. The apparatus can include a link head configured to provide optical communication, a microroom cover positioned about and encasing the link head and a flexure support. The flexure support is secured at a first end with the microroom cover and extends away from the microroom cover, and is further secured at a second end with a structure, wherein the flexure support is configured to flex from a first position when a force is applied to the microroom cover. The present invention optically aligns a first and second free-space optical communication apparatuses. When a force is received on the first communication apparatus a portion of the first apparatus tilts to maintain the optical alignment between the first and second communication apparatuses.

Abstract: A system and method of buffering data of a wireless communication system. The system and method maintain synchronization, end-to-end signaling and coding overhead bits needed to encapsulate data frames sent over wireless media. Additionally, the system and method compensate for transmitting and receiving clock variations. In one embodiment, the system uses framing of data with preamble, stuffing and signaling bits transmitted synchronously at a high data rate in the Industrial, Scientific and Medical (ISM) bands.

Abstract: A system and method for communication of radio frequency (RF) signals over multimedia signal paths. The invention provides a wireless multimedia carrier (WMC) system capable of receiving a variety of standardized input signals, such as DS0/E0, T1/E1, T2/E2, and/or T3/E3 for transmission using RF channels. The WMC system selectively employs time division multiple access (TDMA) and/or code division multiple access (CDMA) technology. The WMC system transmits the various signal inputs using RF carriers, receives the transmitted signals, and converts the signals to the desired signaling scheme (standard) for forwarding to intended destinations.

Abstract: A carrier current transceiver includes a transmitter section and a receiver section coupled to an AC power line. In the transmit mode, input data in the form of a logical "0" enables a carrier frequency signal to excite a tuned cavity. The tuned circuit includes a first winding of transformer, a capacitor and a damping resistor. A second winding of the transformer is capacitively coupled to the AC power line to produce a stepped down carrier current signal to represent a transmitted logical "0". A logical "1" is represented by absence of the carrier current signal. In the receive mode, a small carrier current signal representing a logical "0" is received via the AC line and is stepped up by the transformer and capacitively coupled to an input of the receiver section.
