Distributed Antenna System (DAS)Passive
Passive DAS
In a passive DAS, coaxial cable is used to distribute the RF signals tocoverage antennas. The RF signal is obtained from an off-airrepeater or base station. Couplers/splitters are then used to divert afraction of RF signal along the horizontal floors of the building viacoaxial cabling.

Active DAS
Distributed Antenna System (DAS)Active
An active DAS resolves the signal attenuation problem caused by thelossy coax cable. This is done by adding distributed fiber-opticamplifiers and fiber-optic cable to the passive DAS. It is scalable andcan support multi-bands of services, i.e. cellular, PCS, public safety.

Base Station- Instead of using the nearby cell tower as a signalsource, the wireless carriers may provide a base station onpremise, which generates the RF signals. The base station is
connected via T-1 lines back to the carriers MSO.

Due to excellence in linearity (modulation accuracy), ION-M supportLTE for existing frequency bands and also the new 2600MHz band.Hence, if 900MHz and/or 1800MHz are re-farmed to support LTE &
UMTS, ION-M is the right choice.
