Rocket m2/m5 as Bridge and AP

I have a question about the capabilities of the rocket m2/m5, i would like to use one of the radio ports to act as a client with a highly directional antenna ( 15+km ) to connect to a wrt54g running openwrt.

I would also like to use the other radio port as an access point with another antenna ( ~16dbi sector ) and then bridge the two connections.

Is this possible with the rocket? I will be using 802.11g, my other option is to use two bullet2, but since i will be using solar panels i would like to consume less power.

Re: Rocket m2/m5 as Bridge and AP

This is definitely not possible. This is one
radio/chipset--not two. It operates in
2X2 MIMO. It cannot operate in two
modes at once: access point and client.

Some people have experimented with using
the Rocket in two different directions
(but still in one mode). This isn't supported
by Ubiquiti, and no rigorous tests have been
posted. You're on your own..... Dave

Thanks, I think I may just use two bullet2's then. Its the same price.

Re: Rocket m2/m5 as Bridge and AP

I didn't read your details; do you really
expect to connect to a consumer
wireless router at 15Km? Unlikely,
going toward near impossible...

And you don't describe any of the
access point features. I don't know if
Bullet radios are the choice for either. Dave

Re: Rocket m2/m5 as Bridge and AP

I dont ncessarily need to use the wrt54g, is it possible to do what i was describing with the bullet2? And replace with wrt with perhaps another bullet2?

(bullet2 AP2)----ethernet----(bullet2 client)-----wifi-----(bullet2 ap1)----lan

I don't know what this means.

I assume you are trying to create a
relay for an Internet service.

Internet modem/router <--> access point <~ 16Km ~~>
client <--> access point <~~~>>> local clients.

The client and access point radios form a
relay, connected to each other via an
Ethernet patch cable. Dave

Re: Rocket m2/m5 as Bridge and AP

Sorry to contradict you Dave... BUT some people have had luck using a rocket in just this way!

Key to making it work is making sure the antennas are in such a way you have good separation. Back to back with 3FT has worked for some in 5.8Ghz as a back haul relay.

This has been tested, and someone even posted results of a 5.8Ghz relay in another forum.

I have Rocket2's due in any day now, I will be slapping a grid to one port on Vertical and a Horizontal Sector on the other to do a test.

I don't see why it won't work, you will see a drop in performance for sure. On a pure B/G network I would think it might be too much of a performance hit, but on a N/Airmax network I don't see any reason it won't work (consistently get 16mb to clients 1x1 BulletM2 to BulletM2 using a grid on client and 15db omni on AP in a 10Mhz channel width. Divide that by 2 and you still have enough to potentially serve 20-40 clients @ 2mb).

I am running the test for the same reason, it has potential for a few things.
1. Cheap roof top repeater for small area coverage.
2. Cheap solar repeater for remote hilltop extenders (Bullet & Rocket seen to have same draw of current in bench testing)
3. Cheap solution to get from out building to client house.

If the test works then I can see building many 2x4 guyed solar power hilltop repeaters. Using my primary towers with Rocket sectors, serving some clients from the sectors, but also serving the mini AP's. Most of these AP would only need to get 5-15 clients max.

Either way I will know for sure as soon as stock arrives.

Re: Rocket m2/m5 as Bridge and AP

'headbang', this off-standard idea
has been discussed before, as you said.

I thought I read his post as trying to
make one radio be an actual access point
(shared among multiple clients) at the
same time as it is a client radio.

Your post seems to be about using one
2X2 MIMO radio as a relay. That sounds
like an interesting idea, but the one person
who posted 'results' used a table-top lashup
with direct cables. Then he had one brief
on-air test with preliminary results--that
were fairly low performance if I remember.

That was months ago; a couple of other
people said they planned tests, but nothing.

This sounds interesting enough, but until
you or somebody actually tests it well and
has full results, I wouldn't want to recommend
it. It is way off what the radio was designed for. Dave

Re: Rocket m2/m5 as Bridge and AP

I just got in a 15db airmax sector and 2 rocket2's. This morning.

I personally need to know the results for sure as this has great potential for last mile solar repeaters.

The sector is being installed right now, the first test will be off the bed of a truck then to another truck at various distances.

Second test is more permanent. And will become a new AP if it works. I have a site and 5 potential clients willing to be used as guinea pigs.

Re: Rocket m2/m5 as Bridge and AP

I have a rocket conected to 2 dishes antennas, one for a vilage and one for other, in separate directions and they work very good but it's not posibile to do what you want with a single radio device. Spees is ~70mbps. One link is 4.5km and one 8km.
