Antenna Sharing Challanges

3 sector BTS vs. 6 sector BTS Single band AWS or PCS vs. Dual Band AWS and PCS SIMO antenna sharing is shown below (in-band)

Diplexers required required for out-of-band solution Extra cabling required and RX diversity gain balance No impact to TX side; Minimal impact to RX

MIMO antenna sharing Diplexers required required for out-of-band solution Filter/Combiners required for in-band solution
