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
µWave & RF –Wireless mmWave for LTE-A & towards 5G , March 2017
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
