Enhanced Performance, Flexibility & Features
Wireless Excellence Broadcast ASI Microwave radios are high performance, modern generation wireless networking platforms supporting mixed ASI and IP/Ethernet, interfaces, operating from 4 to 42GHz frequency bands and payloads from 16 to 364, 728Mbps and higher with N+0 carrier aggregation. Wireless Excellence has pioneered the use of Software-Defined Radio which enables in-service upgrades, remote configuration, low equipment costs. CableFree Microwave systems offer users maximum useful lifespan and minimal capital and operating expenditure (CAPEX and OPEX). Advanced networking features in the CableFree Microwave IDU include scalable ASI and Ethernet capacities up to 728Mbps.
The Broadcast-specific ASI interface features are modular and expand in multiples of 4x ASI ports up to a total of 16x ASI interfaces over a link, with between 8 and 214Mbps per ASI stream to support the latest DVB and HD video standards.
Operating distances vary depending on local weather conditions, specifically link frequency and rain intensity.
Planning for microwave wave spectrum use must take into account the propagation characteristics of radio signals at this frequency range. While signals at lower frequency bands can propagate for tens of miles, higher frequency microwave signals can travel only a few miles or less. Higher frequency microwaves can permit more densely packed communications links, with very efficient spectrum utilization. The ATPC feature adapts transmit power to fade conditions, increasing transmit power in high “fade” (e.g. rainfall). The optional ACM (Adaptive Coding and Modulation) feature increases link availability by adjusting modulation scheme in heavy fade to ensure link remains “up” but with reduced throughput. This enables operators to offer high availabilities or to use smaller antennas especially on sites where antenna sizes may be constrained by aesthetics, tower loading, cost or landlord permissions.
