What Are The Options?

• RF Source (needed for all DAS solutions)

Antenna/Repeater

brings in RF from the outdoor cellular network

network

– BTS – carrier installed base transceiver station provides dedicated RF

• Passive Distributed Antenna Systems (DAS)

RF is distributed over coax cables to each antenna from an RF source (repeater or base station)

– Coax cable losses limit their effectiveness in large buildings for higher frequency transmissions

• Active Distributed Antenna Systems (DAS)

Fiber

optic cabling backbone overcomes the transmission losses that occur w/ coax

based system

system

– Electric components convert and amplify signals to RF for radiation by the antenna

– Preferred solution for medium to large buildings

•

Distributed Radios

•

Distributed

Radios

– The systems consist of small cellular radios, called picocells and femtocells to create an internal cellular

network

– Do not rely on the macro network for switching and hand-offs

– Evolving technology often used for ‘Hotspot’ solutions

– Only wireless carriers can provide this
