Abstract

Disclosed is a method that uses existing VGA (Video Graphics Interface) and/or DVI (Digital Video Interface) cables to transmit high-speed digital WLAN/PAN data; also, the disclosed method enables the radio transceiver and antenna(s) to reside in a computer monitor, instead of the less desirable PC housing. Benefits include a solution that results in better range, throughput and antenna coverage than traditional WLAN/PAN integration methods.

Application of WLAN/PAN over VGA/DVI Cables to Enable Embedded Radios and Antennas in PC Monitors

Disclosed is a method that uses existing VGA (Video Graphics Interface) and/or DVI (Digital Video Interface) cables to transmit high-speed digital WLAN/PAN data; also, the disclosed method enables the radio transceiver and antenna(s) to reside in a computer monitor, instead of the less desirable PC housing. Benefits include a solution that results in better range, throughput and antenna coverage than traditional WLAN/PAN integration methods.

Background

Currently, radio transceivers and antennas are located inside the PC housing; the location of these components (the antennas in particular) is not optimal for transmitting wireless data.

General Description

The disclosed method enables a PC’s radio and antenna to be partitioned and located separately from the PC; it also allows the antenna(s) to be prominently located in a near-ideal location behind the plastic of the monitor. The disclosed method enables a very low-loss connection because it allows the antenna(s) to be located very close to, or directly attached to, the radio transceiver. With the radio closely located to the antenna, this minimizes high frequency cable loss and maximizes power to the antenna resulting in better range, throughput and coverage compared with other traditional WLAN integration methods in the desktop. Because the disclosed method allows designers to partition the radio from the main PC housing, mor...
