802.11n

omega-00 · May 27, 2009, 10:11am

All good, I’m currently waiting for my local supplier to get in the mikrotik cards so I can test more, glad to see that the information I’ve collected so far is correct and useful

Are you guys collecting supout.rif’s for devices running with 802.11n? If not currently, do you want any? Or only if we see any problems.

Either way I’ve noticed a couple of issues:

The signal strength reporting for the HT speed rates fluctuates wildly in winbox, this may be a problem with my setup but as noted I’ll check further when I get my R52N’s

Tyronzn
95.7Mbps UDP ? TCP ? packet size ?

the wlan dont detected with TP Link TL-WN851N
x86 with Mikrotik v4.

anyone can help?

did you update license as per instructions ?

The signal reading are combined ones. In future we will improve the signal readings (maybe by adding signal for each chain). If you want to align the antennas, then you can do that by aligning each individual chain.

… and what about users with RB 600, default os V3 and “upgradable to: V3.x” ?

Does each chain (or antenna port) using .11n use a seperate 20Mhz channel or do they all share the same 20Mhz and transmit at the same time and recieve at the same time? I’ve not found any good documentation to explain that.

InoX · May 27, 2009, 8:22pm

that’s the funny thing…you need another RB600 or another license

The "n"card support nstream & 40mhz channel separation?

802.11n tested on RB433AH and R52n

802.11n tested on RB433AH and R52n

in office on RTS-Computers/Bulgaria
from Nicky Krastev and Vladimir

In very soon will testing new 802.11n on distance of 20 kilometers and
will provide demo access .

Got another test from mine as well, first one had some spare antennas of different gain db, now changed to all the same.

Updated the wiki guide to include this image.

Great!

Can you post more details on your hardware configuration?
Antenna, distances, signal strengt..

magnavox · May 28, 2009, 5:48am

Can you post TCP speedtest?

kapulan · May 28, 2009, 6:28am

Great speed!You can test two side the x86 pc based system?

uldis · May 28, 2009, 6:43am

Please upgrade to v4.0beta3 and go to the sysltem license using winbox and update the license, it will give you a key with the correct “upgradable till”

uldis · May 28, 2009, 6:45am

they all share those 20mhz and transmit and receive at the same time.

uldis · May 28, 2009, 6:56am

currently it doesn’t support Nstreme, we will try to add that later.
What did you mean about 40mhz channel seperation? You ment turbo mode (40mhz channel)? N card doesn’t support that, but it can use an extension channel (another 20mhz channel) above or below the center freqeuncy.

niksoon · May 28, 2009, 8:56am

Thanks,
Yes, I will made test x86 pc based system(Gbit ethernet) with two n-radios and bonding in each side, also I will put two dual polarization antennas per each side.
