U.S. Patent Assigned to Laird Technologies Telematics & Wireless M2M Inventors

U.S. Patent #8045592 was issued for work with multiple antenna multiplexers, demultiplexers and antenna assemblies. The multiplexers and assemblies receive signals from the multiple antennas in a system and combines those signals for transmission into a single output. The demultiplexers receive the single input, and output the signal onto separate receivers. The antennas used in this patent included GPS (1574 to 1576 MHz) and world cell frequencies (824 to 960 MHz and 1710 to 2170 MHz).



“The benefit of this technology is that it reduces the number of cables required in a long cable harness, mostly in the OEM automotive market; as they have control over the receiver,” said Ayman Duzdar. “It can also be used in tandem with a demultiplexer of the same nature to separate the combined signals into multiple receivers. It reduces cost which is spent on the harnesses by reducing the number of cables necessary.”



The antenna multiplexers are ideal for any market where multiple antenna signals are being delivered from one antenna module to multiple receiver modules, and where GPS and cell functionality is required.
