1st way of using 3.5GHz: FTTWireless “FTTW”

FTTW B42 Network Design

Minimize Carrier overlap , clearly identified best server

Radio Site Service Availability >99,5%

Receiver signal at least 11dB CINR, never below 6 dB

Generous Nx20 MHz channels to enable 100 time average mobile user traffic

Extremely clean and low latency backhauling

Differentiated QoS by application

Continuous planning activity to adapt offered capacity to demand

Strategic CDN management

FTTW terminal evolutions

Cat.12 will include 4 layers MIMO, 256QAM, 4CA

Very powerful Microprocessor partly devoted to noise reduction algorithms exploiting 4 or 8 antennas configuration

2 Tx, possibly High Power

In order to achieve highest user throughput and best possible spectral efficiency it will require a different cooperative approach between RAN and Terminal
