Beamforming

---

Based on multiple radios and antennas

Wavion’s spatially adaptive beamforming technology is based on 6 radios and 6 antennas, and leverages the multiple signals received and transmitted by them. These multiple signals are properly adjusted by the beamformer to maximize the wireless signal strength at the client modem and the base station modem. This is achieved by assuring that the signals transmitted in each of the 6 antennas sum up into one coherent signal at the client antenna, and similarly assuring that the each of the 6 signals received from the client sum up into one coherent signal at the base station modem.

Exploits multipath propagation

Wavion’s spatially adaptive beamforming technology exploits multipath signals resulting from reflections in the propagation path and turns them into an advantage. This is in contrast to standard Wi-Fi access points which suffer severe degradation as a result of multipath. This ability improves the radio performance in non-line-of-sight conditions and provides more uniform coverage with fewer dead spots.

Improved gain doubles the range

Wavion’s beamforming technology improves the gain of the wireless link by about 10dB.  This significantly increases the range, throughput and penetration in both line-of-sight and non-line-of-sight conditions. The improvement in range and throughput resulting from the beamforming gain are presented in Figure 1, where Wavion's beamforming performance is compared to a conventional access point in typical non-line-of-sight propagation model. Wavion’s beamforming doubles the range and provides much higher rates at given ranges.

Deeper indoor penetration

Wavion’s beamforming 10 dB link gain and its ability to exploit multipath rather than suffer from it provides  deeper
penetration of walls and buildings and
improved uniformity of the coverage.

Resilience to interference

Beamforming provides more resilience to interference due to its inherent directivity. On receive, the beamformer focuses on the user location, thereby reducing the level interference coming from other locations. Similarly, on transmit the beamformer focuses on the user location, thereby reducing the level of interference transmitted to other locations. This ability is critical in large deployments where there is a need to minimize inter-site interference.

FCC beamforming regulation

The U.S. Federal Communications Commission (FCC), in a move aimed at encouraging the use of beamforming, has allowed that total transmission power and antenna gain in 2.4GHz band go beyond the 36dBm limit. Wavion technology takes advantage of this new regulatory rule and delivers 42dBm, which provides an additional 6 dB effective radiated power.
