BulletM2 selectivity

Is there any problem operating two bulletM2's side by side within about 3 feet of eachother?

I have a bullet being used as an Access Point and the one beside it in a point to point link to a remote location.

One bullet is on channel one and the other is on channel 10.

Thanks.

Re: BulletM2 selectivity

It's not a great idea at all--but it's more about the antennas

than the radios. These radios aren't well shielded, and if

mounted close together can interfere with internal noise.

But shielding doesn't work for antennas of course.

 

There may be other more important issues: this band is

a very poor choice for links, unless there's virtually no

interference. That is unlikely in populated areas. use

the 5GHz band instead. And Ubiquiti doesn't provide

directional antennas for this radio.

 

Bullet isn't the best WiFi access point; it's only on one

band, it's not MIMO, and it's an older design.

 

Channel 10 is not a clear channel in most locations; use

channel 11 instead.

Re: BulletM2 selectivity

Thanks for the quick reply.

I thought that given the relatively low power of these units and the fact 

that I was a chunk of spectrum away the units might have a high enough Q to handle things.

As it turns out the performance is not good. 

Thanks for letting me know.

Take care.
