What does Dual Chaining actually mean?

I have a RB912UAG-2HPnD: RouterBoard 912 with 2GHz Dual Chain wireless.

The question I have is what does Dual Chain actually mean? Are the antennas just paralleled and isolated from each other or is it true diversity where the receiver selects the best antenna to use from the received signal strength?

Both antennas are completely separate. They are used at the same time to achieve double data rates.

Ok so that would imply that there are two 500mW transceivers for a total output of 1000mW. Is that correct?

4

if i remember correctly - yes. In MIMO setups that is the case. Total output for 2 chains compared to single chain is around 3dBm higher

janisk, I know this has nothing to do with this problem, but I can't reach anyone from mikrotik since I can't send messages..
