Marvell Introduces Powerful Wi-Fi Featuring Beamforming Technology That Boosts Throughput Performance By Up to 20x Over Existing Technology for Video and Other High Throughput Applications
Marvell today announced that the entire family of Marvell Avastar 802.11n solutions will leverage an innovative transmitter beamforming technology to dramatically improve link robustness for clients ranging from new and existing 1x1- 4x4 MIMO products to legacy devices. Beamforming is a specialized method of radio-frequency (RF) transmission used in Wi-Fi access points (APs), substantially enhancing signal reception at the client and, as a result, extending Wi-Fi signal coverage by two to four times. It can also be used between two clients in conjunction with Wi-Fi Direct™.
Marvell's beamforming technology does not require special antennae or any other cost increase of the wireless subsystem and provides greater than 10dB of perceivable gain in over-the-air tests in home and enterprise environments. This gain translates to an increased throughput of 2x to 20x depending on the environment. Beamforming outperforms other digital signal processing techniques for range extension like LDPC by at least 6 times.
