Room division scenario: Combine with existing operator room division system
The WLAN signal is integrated into the existing operator's room subsystem through the combiner, and a set of room division devices is shared with the operator system for coverage.
The WLAN signal is not in the same frequency band as the GSM/CDMA/3G signal, and the combiner has a high isolation, so there is no interference between the unused frequency bands.
requires attention:
1. The existing room division period (power splitter/coupler/antenna) needs to support the 2.4G frequency band as well, otherwise the room division device needs to be replaced.
2. The link budget needs to be taken to see if the antenna power meets the WLAN coverage requirements, otherwise it needs to be rectified.
3. The sub-AP needs to be in parallel topology relationship, and multiple APs are not allowed to be connected in series on one branch.
4. The combiner must have a high isolation, requiring >90dB to avoid 2G and 3G interference.
