We are at decision time on what to do with the 320/ubnt 3ghz, same boat on decisions. LTE is a brand new horse to us, but the historic issues of interference frighten my more than walking in on my wife with another man when she should be doing laundry, I need clean work shirts. We had done some base testing with baicells and we considering the trigger pull, but we have the 450 out, and its performed as well or better than expected, this is not i or m but it was considered, by us to be a drop in replacement for the wimax, and ePMP to pick up the LOS UBNT junk. Ive been trying to find out what SAS is actually doing real world, but I dont know that the trial operators are allowed to speak of it without ending up in a lake with concrete shoes. If SAS solves all the worlds woes regarding interference, its a cost no brainer to deploy the crap out of baicells, take the range hit, and fill the gaps with microcells where required. but, 450, being the horse it is, works, and works well, even in the interference we have. Its drop in for us on the wimax because we were very careful on EIRP to not push our luck. we may take a 1x hit here and there, but offloading the LOS customers to EPMP will make up for that. May still require the occasional non standard solution for the customers that just dont work on anything other than the wimax, solely because it connected at such a crummy level. We should have addressed them historically anyway though.
