Interference in the WIFI 2.4 Ghz from the U2.1 GHZ cell

[javierinfante]

Hello:
Have any of you found that the Ucell in the 2100 band is generating broadband interference in the WIFI in the 2.4 GHZ band??
We have this situation in several buildings with DAS system, the Huawei HW is only one RFU with many distributed indoor antennas using bidirectional couplers, all passive elements.

Any suggestion??
