Dual chain 900Mhz?

Tue Sep 16, 2014 2:34 am

Are there any plans for a dual chain 900Mhz device? RB911G-9HPnD for instance? I'm looking for an alternative to the rather junky LocoM900 from ubiquiti. The Metal 9Hn looks good, but dual chain is where it's at!

from what I can tell, the Metal 9Hn is just a 2.4Ghz radio shifted down to 900Mhz, that implies to me that there shouldn't be too much of an issue doing a dual chain MIMO device w/ same technique on an RB911G or something like that.

there was 900Mhz, 450Mhz and 145Mhz mPCI boards and some of them - compatible with RouterOS and mikrotik devices.
so far i know, MikroTik make only devices for ISM bands, and 900Mhz had such status in quite limited number of countries, thus reducing acctractivity of reseasing such product dramatically, economically.

Zorro,

new 900Mhz product.

but it's only single chain. dual chain MIMO is good for 2-3dBm of noise mitigation and a significant speed bump. Pretty important when you are limited to 'G' speeds and have limited channels to work with.

I have a few areas that the only thing that will cut through is sub-1Ghz, and 900Mhz is the only thing reasonable we can get into at the moment.

Hi,

Can you point me to the 450 & 145Mhz mPCI boards please?
