FibeAir IP-10’s Key Feature
• IP-10 utilizes a unique Adaptive Codin ! Modulation "ACM# $
Modulation rane% QPSK - 256QAM
• Modulation &'anes to (aintain lin) *'en radio sinal derades
• Me&'anis( auto(ati&ally re&overs to (a+, &onfiured (odulation *'enre&eived sinal i(proves
Optimized for mobile backhaul – all-IP ad !"M-to-IP mi#ratio
