Grounding and Surge Protection
3.9.1 Base Station Chassis and Modules
- A ground lug is provided on the base station chassis (cooling module) for connection
to earth ground.
- Individual base station modules are grounded through the chassis backplane.
3.9.2 Outside Radio Module and Cabling
- A lug is provided on the RRH (Remote Radio Headend) for connection to earth
ground.
3.9.3 Installation Environment
- The base station mounting rack must be properly grounded.
- External AC and/or DC power sources must be properly grounded.
- Power and signal cables running between the indoor and outdoor equipment must be
bonded to ground at recommended intervals.
Important: Grounding connections are provided on all Redline base station and radio
equipment. It is the user’s responsibility to install proper grounding to protect against
power surges and accumulated static electricity. The base station equipment must be
installed in accordance with the local electrical codes: correct installation procedures for
grounding of the transceiver unit, mast, lead-in wire and discharge unit, location of
discharge unit, size of grounding conductors and connection requirements for grounding
electrodes.

3.10 Antenna Systems
The base station supports multi-channel SISO, MIMO Matrix A (STC), and MIMO Matrix
B (2x2 DL, Collaborative MIMO UL). The system also implements Maximal Rate
Combining (MRC) diversity on uplink channels (when MIMO Matrix B is not used). A
