Excellent math work Lutz! Fortunately the poster is not dead :shock: as this link isn't in production on the channel you mentioned. We certainly do not condone or encourage operators to exceed FCC EIRP limitations. In situations where EIRP becomes a factor, MikroTik provides the ability to decrease ...

BrinkNetworks

Thank you for the detailed scan! Indeed, there are a lot of radios there, and some of them pretty powerful. I'm assuming the antennas used are jirous, right? Which model? It would be interesting and useful to see how different antennas (especially mikrotik's and rocketdishes) work under same condit...

Could you post a complete frequency scan from the tower? I find it useful to find out how crowded is the radio space at your location, because some people around here find but most of them don't find an improvement upgrading to AC due to the interference. Is it a shared location with other ISP-s or...

TDMA is auto?

Very nice result

TDMA is auto - Thanks!

We're excited to get more links upgraded. Both towers this link is on have several sectors and PTP links so we're happy to have the frequency back.

BrinkNetworks

We've recently upgraded our second N link to AC and couldn't be more happy with the results. The latest iteration of NV2 is keeping latency in check and throughput is excellent. We're now getting 100+ MB through a 20mhz channel consistently on both links. We've deployed dozens of N links and our exp...

There are several ways to go about the setup you're looking for - for a brief overview.... You only need one Dual Polarity Antenna per side. The 7115HnD should work great. You'll run LMR 400 or a similar cabling from the antenna to the radio. Most of the antennas designed for this purpose come with ...

BrinkNetworks

I could be mistaken but as long as the other clients and access point are using wireless cards with Atheros Chip AR5212 or newer you can run NV2 on your AP. All Mikrotik CPE's (SXTs, Sextant, Groove) support the NV2 Protocol. Without getting too complicated - protocols like NV2 and NStreme operate &...

BrinkNetworks

What Radio Card and Antenna are you using on the access point? There are several Dual Polarity Sectors on the market that might meet your needs. Assuming that the clients currently connected to the AP have adequate signals you should be able to replace your Single polarity antenna with a dual polari...

Here are a few things I might suggest and a few questions as well - Suggestions First - I'd recommend upgrading your firmware to 5.14 - put the notes below into action - and then upgrade to 5.16 when you've got everything where you want it.

It's possible that you might find something if you were to use IPerf and test all the different possible combinations - That being said...we have several APs configured this way in both the 2.4 and 5ghz and haven't noticed a drop in performance for the N clients.

A couple of thoughts - The higher you go...the more interference you're going to get. Use the Frequency Usage and Scan tools at both heights and notice what you see - I'd imagine many more SSID's show up at 500 M than 50 Meters. :lol: The Freq Usage and Scan tools can also help you find a "clea...

1.) I believe the RB800 is better suited for use as an AP with SXTs. Why: The CPU is a major factor when dealing with the higher throughput that N offers...even though it's clock is only 120Mhz faster than the 433AH, it's different architecture (PowerPC) and more RAM actually make it almost twice as...

BrinkNetworks

Aside from your signal levels being too high to get the best performance....have you made sure that your settings match what I recommended at the blog link I posted?

Your signal strengths on chain 0 still make me believe you don't have both chains enabled.

BrinkNetworks

Could you share your signal levels?

BrinkNetworks

There are several things that could cause poor CCQ If you can - you need to improve your signal strengths. Try re-aligning the antenna's. If that doesn't help - You may need to switch to external antennas to get more gain. If you haven't already - work through all of the different channels. And you'...

BrinkNetworks

Have you tried changing channels?

All of your tests indicate you're using the same channel?

Frequent disconnects like that are usually a sign of some sort of interference or RF related issue.

Using 5mhz channels with NV2 saved my bacon on one particular tower I've always had trouble with.
