This all sounds like nomenclature and smoke and mirrors.
If there are two antennas; one H and one V, then it would be 2x2 MIMO, unless you are running more than one radio per polarity. Then it's still not 4x4 MIMO, but more like 2x2 PLUS 2x2?

Confused You need to add to the fact that you can get more 2x the bandwitdh by adding a second ODU and antenna in a setup similar to spatial diversity Using the same channel and polarityŠ So 4x4 mimo in Ceragon terms is: 4 dual core ODUS a (4 radio paths) 4 Antennas Using 2 channels ( can be xpic same channel or 2 HH, 2VV ) Gino A.

They do a bunch of crazy things with combiners, MIMO sync, etc and some creative naming mechanisms. But in the end your standard IP20C with both cores on an 80Mhz channel will do 1.2Gbps or so. The two cores are layer 1 bonded. On Wed, Jan 14, 2015 at 5:14 PM, Peter Kranz <pkr...@unwiredltd.com> wrote:How does ³LoS 4X4 MIMO quadrupling capacity using only 2 radio units² work..?
