Scenario
A LigoWave client from Russia set up a 7.31km PTP backhaul link using RapidFire 6-N (+28dBi Itelite external antennas) to connect several base station/CPE networks, which provide internet access to around 300 clients. Despite the longer distance, the network was not set to operate at maximum capacity because the 6GHz band was clear. The link ran at 20dBm Tx power over a 6.230GHz frequency (40MHz channel).
Product
The LigoPTP RapidFire 6-N is a wireless outdoor PTP bridge for long-distance heavy-duty backhaul and industrial networks. It offers a 1.2GHz CPU, a 30dBm radio, IP67 casing, 2.4MHz management radio, and the W-Jet proprietary protocol delivering 700+Mbps of throughput over 200,000+PPS. The 6-N works over the 6GHz band, allowing users to find less-crowded channels, experience zero noise and interference, and reach greater range and throughput.
Results
Actual daily link use averaged at 150Mbps and peaks at approx. 220Mbps in the evenings. The signal level is –45dBm. Additional real-time tests were done with increased transmit power (30dBm). Throughput reached 240Mbps with around 210,000 PPS (64b) over a 40MHz channel using TCP aggregated duplex. Signal levels remained at –45dBm. Test results show that the 6GHz band is an ideal alternative to the often overcrowded 5GHz.
Summary
Test results show that the 6GHz band is an ideal alternative to the often overcrowded 5GHz. Not only does it provide the needed conditions for good signal levels and great performance, but it also allows networks to operate at lower Tx parameters, this way reducing self-interference among sites. Besides that, low noise levels also mean longer potential link distance.
