But, we decided to buy a couple RF Elements carrier class sectors that have fantastic 5.1 performance. Putting these on the ePMP radios (we had decided to move past Ubiquiti by now) brought our signals from around -65 to -55 and added 10 dB to the SNR. Speeds increased around 25 Mbps. This is just by putting these sectors on the AP. I am very pleased with them and would recommend anyone needing a sector antenna, look at RF Elements and if you are 5.7 / 5.8 Ghz, try a TwistPort. You won't be disappointed.
We created a detailed spreadsheet (thanks to the RF Elements beta program) were we tracked upload and download signal strength, SNR, radio to radio speed tests and speed tests to the Internet over a 100Mbps connection. We ran 2 full sets of tests with the Rocket 5AC PtMP radio - one into the UBNT AC sector and one into the RF Elements TwistPort. We had about 12 test sites in the coverage area and tested both the NBE and PBE radios at each location.
Then, we repeated this with the Cambium ePMP radio. Two full suits of tests with the Cambium 120 sector and then the RF Elements TwistPort. CPEs were Force 180 and Force 110 radios at each test site. These are almost exact matches to the NBE and PBE products from Ubiquiti - except Cambium does not have an AC product.
After all this, two things were very clear:
1) My wife was getting very tired of the UPS guy stopping by every day with boxes.
2) Cambium ePMP products out performed Ubiquiti AC equipment in our test environment 95% of the time (there was one radio location where UBNT gear was slightly better in speeds).
If you are interested in seeing the full spreadsheet, contact us and I will be happy to send it along. It has been shared with RF Elements (as part of the beta program) and Cambium.
While none of this was written as a paid endorsement, I am very pleased to be working with Cambium for our co-op WISP and thank RF Elements for a well performing antenna line.
