Just announced to distributors and available, the new R52Hn looks like a winner. Mikrotik took the best of the R52H, the R52n, and the R5H to create the complete radio card. It supports both 2.4GHz and 5GHz, 802.11a/b/g/n, with up to 320mW transmit power, up to -97 dB receive sensitivity, 2x2 MIMO with dual MMCX connectors, and improved ESD protection, all in the same price range as an R52H.
I can’t wait to get my hands on these and test them in my network. If it performs as well as it looks in the specs, I’ll be using this card everywhere.
I hope it doesn’t go up in smoke when changing channels, like the R5H.
I also hope it won’t suffer from 2.4 GHz interference when running at 5.8 GHz because of the dual band operation.
Today I set up 2 RB800 routers each with a new R52Hn radio card and dual omni antennas. I only had about 30 minutes available to set up and test them. I used the vpls bridge. I was running the bandwidth test program on the RB800s which is not ideal. I’ll try to get more time tomorrow and run the test program on other RouterBoards.
Freq was 5180. 802.11a mode worked fine as expected and I had about 20.5Mbps throughput with tcp both directions. CPU was at 11%
Next I turned on 802.11n mode with 2 chains and saw the throughput jump to about 50Mbps tcp in both directions. CPU was at 100%.
Wow, that is impressive. Guess I’ll have to deploy some 802.11n in the field.
It also shows that you need a fast CPU for optimal 802.11n. I plan on using the RB411AH for all my outdoor PtP 802.11n links until an RB411G comes out.
Will 3 of these cards fit in a rb433ah? Wonder if Mikrotik will ever modify boards to accept major brands of high powered radios since they are thicker? Shore gets old having to put two boards with 3 radio slots each, just to get to use 3 high powered cards not to mention breaking my piggy bank and 532A’s with daughterboards are running low at my place.
50+ RB’s and counting
but in the end… a hellava lot better than all the other alternatives.
Heya I’ve got a question: Is the reported 25dbm achieved in single chain mode or this is sum of both chains(meaning that single chain setup will have 3dbm less)?
Anyone else test these yet to see how well they perform? Do they outperform the R52n? I’ve had no luck getting anything greater than 30 Mbps UDP on 5 GHz or 2 GHz. I’ve tried several different people’s configs who say they get close to 100, but not me!
