View Full Version : Connecting Bullet M5 to Rocket M5
Is the Bullet M5 fully compatible with the Rocket M5 and NanoStation M5?
Will AirMax work, but without MIMO?
It looks like like Ubiquiti doesn't have a medium range CPE product otherwise.
The Nano Station is short range and the Dish is long range.

Yes, great line up - I am blown away, but a 20dB directional integrated panel/box device would be nice too. (Like a Rootenna but with nice Ubiquiti design!) Even better, with 2 x 2 MIMO.
You can't please all the people all the time.....!

Curious on this as well... Also, maybe I haven't dug deep enough, but are there any better technical specification docs out there with regards to the entire suite of AirMax products?

You can likely use an Arc ARC-ID5823B88 with a Rocket, but the price is a little scary.

I just want to re-hash this one to be absolutely sure...
If I use the Rocket M on the Ubnt sector, and I have many Nano Ms connected to it, but then I connect a single bullet M to it... What will I lose? Will the bullet operate a little slower since it doesn't have the Mimo, but will it also affect all the other associated clients? Or just itself?
This is with Airmax turned on.
This is a good question. From what I read it should not affect the NanoMs. But it makes sense to make sure from Ubiquiti on this one.

Hey Guys,
The Bullet's will talk with the rockets without issues. You can have an intermixed network of 2x2 and 1x1, and due to the AirMax it will not impact performance.
The main thing that will impact the entire network is sub par signals and fade margins.
Thanks,
Mike

Even G based SISO clients? Without Airmax of course.

G clients will lock the AP out of the N protocol and you will lose all advantages of it. It is best to stick legacy products with legacy products.

Ok, so the Ubiquity products aren't capable of running in mixed mode? That's what I'm trying to figure out, the $20 N routers at Staples support N/G/B simultaneously, w/MIMO on N. I'm trying to come up with some sort of upgrade plan, Ubiquity doesn't seem to want to make it easy.

Hello,
They will run in mixed mode, but as with any mixed mode operation the N protocol is basically dropped off at the wayside so that legacy products can still pass data.
Thanks,
Mike

It appears that Airmax is all or nothing which makes sense to me. Going from CDMA to TDMA are 2 different animals.
I take it that with Airmax on it simply ignores regular B and G traffic all together? I can imagine it would be difficult for airmax to dynamically turn on and off several times per second to accommodate both radio classes simultaneously while still maintaining the benefits of airmax... Seems to me the 2 delivery methods are so fundamentally different the AP could not get the packet timing close enough to be useful.

Hello,
With AirMax on the AP wont even recognize non-airmax devices.

Which is a good thing to scare wardrivers off your base station...

Is this while using the BulletM in 20MHz mode? Which I am guessing the rest of the line operates in by default...?

Just looking at the specs for the sectors (http://ubnt.com/downloads/AirMax5GSectors.pdf). Aren't beamwidths measured based on when the signal drops of by 3dB? The spec sheet suggests these are calculated on 6dB. Is this just a typo?

Appears to be the same as

Mike, can we get a full list of the available PDF specs?

No, one can have a 3 dB or 6 dB or 9 dB or 1.5673234 dB beamwidth. It's not wrong to use any dB value for the beamwidth, as long as it is clearly stated.
It's not wrong to use any dB value for the beamwidthIt just goes against the established industry de facto standard of using 3 dB down for you halfway beamwidth plots.

That's a shame. Was hoping it was a typo as we currently use 18dB 120' sectors which have squeezed the elevation beamwidth down from 8 deg to 4 deg.

So do you want the elevation beamwidth to be 8 degrees or 4 degrees?
I suspect the elevation beamdwidth in the pdfd is 3dB.
It's not wrong to use any dB value for the beamwidthIt just goes against the established industry de facto standard of using 3 dB down for you halfway beamwidth plots.
We prefer to consider the coverage of a sector a larger number than the 3dB angle, and 6 dB is a good compromise.
As 3dB is a usual number, it would be good to also state it, but considering a real coverage angle is a good thing Ubiquiti did.
