4G LTE Signal Interference

I am using ZoneDirector 3000 to manage ZoneFlex 7343. Recently, i am facing a problem about 4G LTE signal interference. The wireless signal still can maintain around -69 to -75 dbm. However, the throughput has been dropped below 1Mb. Do anyone has the similar problem? Do you have any workaround solution for it? It is because we can't manage or control the carrier to deploy their equipment.

Some of our newer models such as the ZF7352 (which is similar to your ZF7343), ZF7372 and ZF7982 have special interference filters which help reduce this specific problem.

That's the kind of info that would be welcome sooner rather than latter :).

We would like 2 meters separation from 4G LTE antennas and APs if possible.

For both sites, collect AP support info with APs hard-coded to channel 1, 6, 11,
and analyze Athstats RF Histogram, showing 2 minute sample of RF interference
levels, to help determine if one of these three channels is any better/more useable.

"Good" levels would be reported with less than 5000 PHY errrors per second seen.

Histogram of PHY errors per second (pcttime in each range)
0 1-500 ..1K ..2K ..5K ..10K ..20K ..50K .100K more
0 92 4 2 1 0 0 0 0 0
