CalAmp Corp. has been awarded a new U.S. patent for “Wireless communications structures and methods utilizing frequency domain spatial processing.” The patent outlines a system for wireless transceivers that are connected to spatial processing channels and covers a system to enhance overall performance of a wireless broadband network when multipath interference is present.
CalAmp is a provider of wireless products and engineering services. The company’s development efforts have created beamforming technology that may be leveraged to enhance performance and coverage of WiFi (

Alert) and WiMAX networks. The technology utilizes multiple antennas and DSPs to form an antenna pattern optimized for each network user based on interference and other wireless channel conditions.
Spatial processing cancels interference by utilizing high multipath, non-line-of-sight channels and improving data throughput performance. This improves performance and reduces dead spots to enhance the user experience with demanding and mobile applications like VoIP.
"This patent is the latest in a series of patents related to smart antenna technology awarded to CalAmp over the past few years,” said Fred Sturm, president and CEO of CalAmp. “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."
