There are couple of new products that cambium is pushing out to the market, the cnMedusa pMP 450m and the ePmP 2000.
The ePmP 2000 will be compatible with the ePmP1000 AP's and CPE's, but if you are starting from zero better get into the ePmP 2000 for high interference areas, or simly go with the standard ePmP1000
I forgot to mention that snMedusa and ePmP2000 are in pre-order phase I believe and should be out sometime this sommer, correct me if I'm wrong, but I havent seen any deployement yet.
