Hi Mike,

We had the target signal as per the B5's GUI indicated we should have, there is a fair bit of noise in the area, however, the UBNT PowerBridge that was doing the link at 30MHz channel bandwidth was passing 70-80Mbps.

Our engineers spent as much time possible aligning the link, we had a team at each end assisting in this.

We reviewed with Mimosa and our Distributor, but there's only so much time we could spend on this link. Once the newer firmware was released (I think v1.2.0) we tested again and got better performance so this may have been an early problem that has been ironed out now, but for me I would only use them on smaller distance links. YMMV

I think there is some information missing on your longer link. Did you still have appropriate signal? Was there noise?

I have a B5 link that's about 2 miles that's rocking full data rate and a B5c one that's going about 4 miles at full data rate. My 8 mile B5c link is less than full data rate due to interference.

We've deployed 2 B5 links into production, the newer firmware seems to have fixed the issues we saw in the links when we first tested them.

We have a very rural customer where two hops are needed around the site. We're lucky in that we had two 80MHz channels free. We see around 350Mbps both ways actual throughput on both links.

However, these links are short est. 200mtrs when we had tested these on longer links their performance was awful, on a 40MHz channel we saw 20Mbps.

For our longer links that need a bit more throughput than a Rocket M5 we either use Licensed radios or the AF5X which works very well.
