Oxnard, CA -- CalAmp Corp. announced that the U.S. Patent and Trademark
Office has awarded CalAmp a new U.S. Patent titled "Wireless
communications structures and methods utilizing frequency domain spatial
processing" (Number 7,072,693). The patent outlines a system and method
for wireless transceivers that receive and transmit signals from an
array of antennas that are connected to spatial processing channels. The
patent's claims cover a system to enhance the overall performance of a
wireless broadband network in the presence of multipath interference.

CalAmp's smart antenna
development has resulted in beamforming technology that can be leveraged
to enhance the performance and coverage of wireless networks such as
WiFi (802.11) and WiMAX (802.16). It uses multiple antennas and digital
signal processing to form an antenna pattern optimized for each network
user, based on interference and other wireless channel conditions. The
complex spatial processing cancels interference by utilizing high
multipath, non-line-of-sight channels.
Fred Sturm, CalAmp's President and Chief Executive Officer, commented,
"This patent is the latest in a series of patents related to smart
antenna technology awarded to CalAmp over the past few years. It expands
our intellectual property portfolio and demonstrates the Company's
innovation and leadership in wireless technology. Spectral efficiency
and methods to improve performance in a crowded wireless spectrum and
challenging RF environments are critical issues that many companies in
this industry are trying to address today. CalAmp's proven and patented
technology helps solve these problems."
Other patents that have previously been awarded to CalAmp include
"Wireless communication structures and methods with enhanced range and
performance" (Number 7,035,652) and "Spatial-temporal methods and
systems for reception of non-line-of-sight communication signals"
(Number 6,947,507). CalAmp's patent portfolio also includes other
patents pending in the U.S. and in other countries.
