Sr2 as AP compatabillity.

spire2z · Tue Jan 17, 2006 1:00 pm

I'm thinking of swaping an old Smart Bridges AP to an RB with SR2 unit. Most of my existing clients are Linksys Wet11 (old ones) / Senao CB3+ / Pheenet wap 454 g.

I just wondered if anybody else found compatabillity issues with existing client units? Also can it operate in mixed G/B mode and still allow old B clients to connect?

Thanks in advance if anyboby can help.

It will work with in b/g mode but it won't get you anything as the it will default to the the lowest level (b) to be compatible so unless everyone is g it won't help much.

Thanks for the advice

I thought that would probably be the case but the extra sensativity and power will be a good advantage anyway to make worth the purchase. It does also add a level of future proofness!!.

I also did wonder how the hardware really handled the mixed environment. Can they only operate in one speed for all clients connected? or is it when the clients are actually transfering data that the speed adjusts to suit?

I changed over from prism2.5 cards to the SRC cards and in b/g mode most of the CB3s would not connect anymore so I had to change it to b mode only.
I also have DLB2300s and some of those dropped off as well.
I've got all but one DLB2300 back on, but I hope today I will have all the problems worked out.
I think it's not so much a MT issue as much as a chipset problem.

I replaced a CM9 with a SR2 and all of my CB3 are connecting without problems.

I also have other b/g units on this ap, but the AP is set to b mode.

Looks like B mode for me? Thanks for your input...

From my understanding (correct me if I wrong) is that if there is a b user associated everything (all g users) will down grade to b. So in effect you will need to have all users running G before you will see the increased bandwidth. It will not pick and choose depending on who it is talking to. 802.11n which is in a lot of ways a replacement for B/G will allow for higher speeds based on each connection. Product is rumored to start to flow by late summer.

Might be a little off topic too but have you seen:

They claim to just have developed a NLOS system capable of 60 mbps over 26 miles omnidirectional or something. Check it out. Very exiting unless it's a scam.

To stay off-topic:

Reads interesting, BUT: (quote from their website)

Radio chips for devices should be in the $5-$6 range when built in volume while base stations will be around $350,000.

The pricing for the base station is a killer for most MikroTik users, I suppose. And that probably won't come down, as the receiving circuitry sounds to be quite complex...
But nice one to follow

Best regards,

Thanks cmit I didnt read that bit

I have also been conducting some tests in 802.11 mixed environment and it seems that it is capable of doing both rates using sr2 With mixed clients connected simaltaniously. I tested with senao nl-2511cd plus ext2 mercury B only pcmcia card and it could do around 5 mbps average. I also tested a pheenet wap-454g B/G ethernet bridge and it was doing average 10.5 mbps. This was indoor with both units connected simaltaniously. Looks like it is better.
