How does AAV work? Depending on the site, does the vendor run fiber to a box (aka switch) that basically supplies any company that wants access to their hookup? So say, comcast runs fiber to the tower, they offer ethernet hookups to their fiber connection for x a month and that would be called "ethernet based backahul"? Then, in the case of direct fiber connection does fiber run straight to a new sprint basestation?
What sort of backhaul is being piped into basestations? You mentioned that Chicago is getting DS3's via centurylink (single or multiple DS3's per basestation?). I guess I am wondering if Sprint is going to run into backhaul issues again in the future. It's hard to imagine going from bundled T1's to a DS3... but 45mbit may cut it for now but won't cut it once they add another 5x5 carrier.
I'm not certain how the service is terminated for use at sites. However, when it comes to AAV Contracts, they are under master backhaul agreements. Sprint put out to bid their backhaul needs, and they included minimum throughput standards. So even AAV bidders still have to meet those standards, the same as microwave and fiber vendors have. AAV can be scalable by just adding another headend unit at the base station, should capacity issues arise or more carriers are added. However, in the instance of cable companies, the type of commercial grade backhaul they end up providing to Sprint is much better and faster than home service cable. Many cable companies are using fiber backbone now and can extend that fiber to the site in some instances. But this would still be considered AAV because how the service would be terminated at the site.
The great thing about AAV is it creates a competitive outlet for the whole process, lowering prices on all types of ethernet backhaul. And allows carriers to get less dependent on one type or only a few companies. In Network Vision, Sprint is using dozens of backhaul vendors. I may create a list. Thinking about it.
I don't have any more details about the CL DS3's now than I did then.
