Deployment model: dimensioning• Model computes* Backhaul capacity and configuration: number of hubs, sectors and modems

upon cases’ entries for dense cities or residential area and with allocated spectrum. • Dense cities mobile application inputs: population and density • Residential fix application: population and house-holds density • *beforehand models computes cells radius upon required service and cells capacity upon

spectrum

Interferences –frequency re-use 1:2– Model includes interferences computation between neighbors sectors :TH and terminals

STATUS • Integration of technology has started for RF front end

modules • Products to be assembled and tested Q3 2017• Installation and networking in Valencia Q4 2017

• Field test and demonstrations Q1 2018

Status and Field Trial


High capacity distribution problem is solved with PmP and TWT Power @hub. • Simple networking and installation

• Adaptive capacity and load balancing: upload down load and 1 to N

• N+1 Products instead of 2N (PtP)

• No frequency plan and best frequency re-use (1:2)

• No high precision pointing, gain maintained

• Lower foot prints

• TCO cheaper: 40% less than E-band PtP & > 3 times less than fibre optics.

• Pay as you grow

Conclusion• Increase efficiency

• Decrease installation burden

• Decrease all costs
