I am wrapping my mind around the myriad of RAN solutions out there, and I would appreciate it if someone had a good overview of the subject or could direct me to new vendors worth investigating. So far, I see ones that are designed to (a) increase coverage, (b) increase capacity, or (c) do some combo of (a) and (b). Some solutions suck in the donor signal (antennas on top of roof) and then blow it back indoors on various frequencies. A good example of this is something like Axell, which doesn't appear to add much capacity, just stretch the existing uplink's capacity by amplifying the signal indoors. Other solutions (IP-RAN, E-RAN, etc) have an Internet / IP component and allow for all sorts of cool things (synchronization between units for soft handoff, etc). SpiderCloud seems to be a good play here. Then there are other niche plays that don't do everything, but seem to be good enough for various applications, like SMS texting. If I remember right, IPAccess did this sort of thing for schools (which is perfect for emergencies). Any others I should look into? I'm primarily interested in carrier-grade ones... -- Also on LinkedIn? Feel free to connect if you too are an open networker: scubacuda@gmail.com
