Assignee:

Wireless Facilities, Inc. - San Diego CA

International Classification:

H04J 306

US Classification:

370503, 370506

Abstract:

A system and method providing a structure to the data sent over the air interface of a wireless communication system. The system and method allow compensation for transmitting and receiving frequency variations, synchronization at the receiver and provision of a virtual signaling channel 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.

International Classification:

H04B 700

US Classification:

370310, 370465

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.

International Classification:

H04L 700

US Classification:

375372, 710 53

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.

International Classification:

H04Q 7/00

US Classification:

370329, 370437

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.

Assignee:

LightPointe Communications, Inc. - San Diego CA

International Classification:

H04B010/00

US Classification:

398/129000, 398/119000

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.
