MMW 10 Gbps Technology that Works at Heavy Rain
Dmitry Tsiryulnik, CTO of Challenger Broadband LLC shared his view on PPC-10G-E Adaptive Code and Modulation (ACM) feature.
‘Today (August 2, 2017) we had heavy rain come through Manhattan today around 12:30pm -1:30 pm.
During that time multiple fixed wireless links operating in the 80 GHz range and at distances over 1 mile were getting reported as down, fluctuating or operating at severely diminished capacity.
Meanwhile, the Elva-1 demo link spanning 2 miles between Tribeca and Midtown Manhattan performed admirably. The modulation had dipped down to -48 and throughput went down as low as 5.2 Gbps from the optimal 10 Gbps but the link never went down.
This was a very impressive performance from these radios”.
