The company 3tech S.A. of C.V. I carried out the comparative test taking into account the following antenna models: Ubiquiti RD5G34 and NetPoint NP3 with Mimosa B5C Radios. To see the real impact, it was decided to install the antennas on a problematic link with a distance of 109 kilometers and a considerable noise level, for which it is necessary to pass 50 Mbps. Symmetrical, reliable, after 3 weeks of testing, the following results were obtained:
Link spectrum at different times
The comparison with the RDG34 chainring
There is the problem of constant disconnections and low traffic measurements in one direction as shown in the image, normally the least traffic occurs in the direction where the reception location has the highest noise index, this link became a problem, because it had to be constantly monitored to change frequencies every time the link was disconnected or degraded.
NP3 antennas installed
Better link stability is achieved, with an increase in the signal level of approximately 3 dB, but performance increases, achieving after 3 weeks of testing, a sustained average traffic of 100 Mbps x 100 Mbps with the same bandwidth in both directions, which we had not achieved with the previous antennas, clarifying that if equivalent measurements can be obtained with the ubiquiti antennas, the significant difference is in the quality of the link.
The tests were carried out on a link in operation, to be able to see the immediate real benefit, and to be able to define a useful data to take as a reference for future links, because the antennas were replaced, it was not possible to do simultaneous tests, for that reason, it is considered a preliminary test, the tests were done, with the feeder at 90 Degrees, it remains to test at 45 Degrees, we tested 1 month with the feeder at 90 Degrees, we will change it to 45 degrees and in One more month we will have the average of the tests.
