Sooo.... I can answer some of your questions and provide you with some spec sheets.
ATM... speed performance is very similar to Baicells 2.5 product as all testing is currently with Cambium's CAT4 UE. Speeds will improve with more advanced features being unlocked and future higher CAT level UE's.
The first Cambium RRH will be a 2 watt per port (there will be a 10 watt version later on). Right now it only has 20MHz channel support with additional channel support (5, 10, 15) coming soon. N=1 frequency reuse will be supported later on.
There's not going to be a low power option... just the 2 watt RRH is a minimum of 55-70 watts by itself not including the BBU which draws 90-120w (which will be required to drive the RRH). Side note, you may want to consider Baicells Nova 227 eNb which uses less then 20 watts for micro cell applications.
Cambium UE's support upto 26dBm power output, vs. the typical standard of 23dBm. This extra 3dBm power paired with the integrated 15dBi dual-slant antenna can make a huge difference on a nNLOS connection over competing products.
