Properly control the distance between antennas. It is recommended that you comply with the following requirements:
[Outdoor scenario]
If antennas are to be deployed on different poles and face opposite directions, ensure that the horizontal distance between the antennas is at least 1.5 m. If antennas are to be deployed on the same pole and face the same direction, ensure that the vertical distance between the antennas is at least 5 m.
Keep antennas at least 2 km away from 4G signal transmitters (towers).
[Indoor scenario]
Ensure that antennas are deployed no less than 7 m. In semi-open indoor areas, ensure that APs are around 20 m away from each other.
Deploy antennas at least 2 m away from 4G antennas.
Keep antennas away from electronic equipment that may cause radio interference, such as microwave ovens.
[Vehicle-mounted scenario]
Deploy antennas at least 5 m away from each other.
Keep antennas at least 2 m away from 4G antennas.
[Trackside installation scenario]
At the same trackside, place antennas with the same direction at least 50 m away from each other, and place co-located antennas facing opposite directions at least 20 cm from each other.
Ensure that the height difference between trackside antennas and vehicle-mounted antennas do not exceed 0.5 m.
