What’s TETRA ?
Answer: Terrestrial Trunked Radio
What’s BDA?
Answer: Bi-Directional Amplifier
UHF / TETRA BDA is designed to provide a more cost-effective solution for indoor coverage of signal enhancement to provide reliable connectivity with radio users (Portable).
TETRA Repeaters Coverage Solution Systems Realizing In-Building and Tunnel Coverage for Critical Communications.
The BDA works as repeater between the Base station and mobiles. It receives the low-power signal from Base station via the Donor Antenna or through Transmission line, it further amplifies the signal and then retransmits it via the Service antenna to the weak/blind spots.
On the reverse path signals from mobile radios area amplified and retransmitted to the Base station.
On the reverse path signals from mobile radios area amplified and retransmitted to the Base station.
