Straight Path Communications announced that its subsidiary, Straight Path Ventures has successfully demonstrated a 39 GHz 5G Transceiver prototype at its Gigabit Mobility Lab in Plano, Texas. The prototype unit supports the entire 39 GHz band. The indoor test demonstrated wireless transmission of a 500 MHz wideband signal with 64-QAM modulation and beamforming.The transceiver system consists of 144 antenna elements (72 for transmitter and 72 for receiver) and 8 transceiver chains. Each transceiver unit provides 90-degree sector coverage and can dynamically form beams with half-power-beam-width as low as 10 degrees within coverage. The prototype has a compact form factor (12” x 8” x 5.5”), weighs less than 7 lbs., and consumes less than 100 watts.However, this transceiver is only in the developmental stage, there are no guarantees that the efforts will result in the development of a commercially viable product, and Straight Path may discontinue development at any time as results and prospects warrant.
