Hi, I'm using two LHG 52 AC (RBLHGG-5HPacD2HPnD), ROS 6.44.5, for a link of about 4km, no obstacles. I managed to get a throughput of about 350-380Mbps on the 5ghz band, and about 80 Mbps on the 2.4ghz band. Since the goal was to share an asymmetric internet connection, I decided to split the download and upload traffic via OSPF and MPLS to maximize the throughput (no continued tx/rx switch on both LHGs)
In the last 3 weeks, however, the capacity on the 2.4ghz section has drastically decreased (about 40mbps) probably due to some noise: now I'm using 2407 mhz as frequency (20/40Mhz Ce, N) and I would like to go to a lower frequency, since I am licensed.
Originally, freq was 2387 mhz, then I moved because I started experiencing "strange" problems: in practice, the signal received by only one of the antennas fluctuated continuously, without variations in the noise floor, 10dB lower, and then stabilized on a very low value (12-13 dB lower).
Changing the frequency, the situation has not improved immediately, but about ten days later, first with a fluctuation (opposite than before) and, in the end, with original dB values.
In short, I am afraid that setting my LHGs at a lower frequency than the standard ones could make a damage at them, so now them are set at higher and standard freq.
It is possible that bringing those devices to those frequencies ( <2400mhz ) can damage PA or the receiver, or the problem has to be found in interference or other? (although the scan or frequency usage functions do not indicate anything relevant and the NF is always very negative)
Thank you
