Anyone know if the SR9 card is going to be supported by Mikrotik? (900Mhz Atheros)
http://ubnt.com/supper_range9.php4
I haven’t seen anything on the forums regarding it.
It’s been discussed around here, just search for sr9.
I think it’s very likely that it will work fine, since it appears to be a standard Atheros AR5413 (same as the EMP/SMP cards, and I think the R52 as well), just with a custom RF stage.

We’ve been using it on 5.8GHz. Working very well, being 400mw and all. It does get a bit more hot compared to a CM9 or normal Atheros card, but its worth having. It works on any 2.9.x ROS. (Haven’t yet tried it on 2.

Somehow I doubt that, it being 900Mhz and all. 
(Not to mention that no one I know of has seen anything more than a prototype as of yet.)

We have tested it and it is really working at 900Mhz. As I understant they are converting the 2.4Ghz to 900Mhz…
Next week we will test in real enviromet (few km distance) and then we will have some results.
For now we can get approx: 5Mbps using 5Mhz channel; 10Mbps using 10Mhz channel; 20-25Mbps using G mode; 7Mbps using B mode.
For now in the RouterOS to get is working you should use these frequencies:
2422Mhz → 922Mhz
2427Mhz → 917Mhz
2432Mhz → 912Mhz
2437Mhz → 907Mhz
It is a workaround for v2.9.x till the v2.10. In v2.10 you will be able to select the 900Mhz frequencies directly.
Wow, that is good news. Keep up the good work.

Now if only we could use this in Germany …

How about the SR3? Will support for that also be included in 2.10?
we haven’t received the SR3 cards so we don’t know yet.
I may be reading this wrong, but it seems the sequence of frequencies doesn’t match between 900 and 2.4. 2.4 ascends, 900 decends.
Is this right?
Thanks

Correct.
i m really want to know the range of the 900mhz NLOS, how many KM we expect if its NLOS, please plece your post guys
As with all radios, NLOS performance will be entirely depend on what is causing the NLOS. Trees?, Buildings?, Hills?, Walls?, Multiple?, Thick obstructions?, Thin obstructions?, Fully blocked Fresnel?, 50% blocked Fresnel?, etc…
It is pretty much imposable to pre-determine NLOS performance, without knowing exactly what is in the way. And even then, it isn’t easy.
That said, 900Mhz will be better than 2.4Ghz at getting around things. Also OFDM helps compensate for multi-path, so in theory, it should perform better than existing 900Mhz systems.

ok in case of blocked fesantal zone 50% only
You’ve got the answer in the upper post.
Just buy equipment and test … Nobody can say for sure.
i will but i m looking for estimation
example i have link @ 6mbps arround 12km @ 2.4ghz 200mw 20db antenna both sides
if i replace it with the 900mhz 700mw whats the expected speed i will got? if we consider my antenna is somthing like 15 db
another word guys, can i install it from car to car?
I’m thinking bicycle to bicycle might work.
its not a joke u have to understand what i mean 1st
i sent e-mail for them to buy the SR9 a, waiting for the reply
I thought you said that after 2.9.10 you would select 900 channels
