I have one doubt. Let's say that one SD/HD channel takes 1Mbps (just to make math simple) and let's say that the number of total available channel is 50. (the total number or channel is not a real problem to me, but let's say the number is very high, 50 or 100) Multicast can help a lot (if it's broadcast not video on demand) but my doubt is about the number of simultaneous IPTV channels per sector antenna (i.e. per radio channel). If you have 20 customers on the same sector, each one of them watching a different TV channel you need 20Mbps per sector + the normal internet traffic. Let's say 30Mbps per sector. Or you can think to use a second sector IF the area is not so crowded. So the more successful is the service, the more problem you have on the radio channel (access network). So my concern is not on the backbone, it is on the access network. Another point is: what happens when you experience interference in the area? Web surfing can be acceptable with some interference, but IPTV is a pain. Personally I would feel safer in licensed frequencies, but this is my feeling, comments are welcome also about this. Other doubt: one user means maximum one channel per user? Or the same user can watch multiple IPTV channels at the same time? (e.g. I have 2 tv, so I put two IPTV boxes kids watch Disney, I watch football) Any wireless operator that is massively using IPTV wants to comment? Thank you -- Ing.
