Off air or BTS Fed systems

How does it work?

An off-air digital repeater receives the radio signals to provide coverage inside small buildings to feed an optical system, or we have direct BTS connection to cover larger buildings, tunnels & metros. www.cobham.com/wireless

Why in-building coverage? Outdoor cells might be blocked by high penetration loss of modern buildings Dominant cell definitions often disturbed by multiple cells from outside Massive demand for capacity requires dedicated in-building sectors

Applications

• Airports • Railway / Metro Stations • Shopping Centres • Public Buildings and Areas • Stadiums • Corporate Headquarters • Power Stations • Railway / Metro / Road tunnels • Manufacturing plants • Mines

The equipment

D-CSR – Digital Channel Selective repeater

21

OMU – Optical Masterunit BSF – Band Selective Fibre repeater

21 February 2016

www.cobham.com/wireless

Key Benefits

RF over fibre • Reduced frequency requirements • Improved system capacity • Easy to expand system – More frequencies – Additional equipment locations

• Reduced Switch loading • Less backhaul links • Single or multiple bands in same box (for example Tetra +

LTE). • Cheaper than BTS solution. OMU + 2 optical repeaters circa $25k 22
