Magis Networks, a start-up based in San Diego developing WLAN chipsets, was awarded several patents by the U.S. Patent and Trademark Office in the areas of 5 GHz antenna design and 5 GHz wireless local area network security. Three of the patents cover the use of multiple antennas to overcome multipath issues in an indoor WLAN. Multipath issues occur when a radio frequency (RF) signal travels over multiple propagation paths from a transmitter to a receiver. These signals are reflected by various objects in the home or office causing them to arrive at the receiver at different times, thereby resulting in constructive and destructive interference. Magis also received a patent for enhanced security technology that employs a form of sophisticated waveform encoding of the 5 GHz transmitted signal.
