There are PTP and PTMP applications that do 600Mbps+ full duplex if required. To ask for 100Mbps allows for greater distance, cheaper cost and use of unlicensed frequencies. With proper planning and rate limiting per client on the LAN you can easily handle over 100+ computers for WAN connectivity and that includes YouTube.
Radio's costs could be 25K for a link (2 radios). However sometimes the cost of running fiber for a mile or two could cost more than 3+ times the cost of a link itself and simply requires line of sight.
Some radio's also provide for link aggregation (LAG) so you can combine a set of ports to increase the throughput of two links into one for extra capacity.

Not what I'm getting at at all.
What I'm getting at is, how much is this going to cost per month for each school? Plus, if some schools can barely get a T1, how the heck are they going to deliver 100mbps in the area?
They complain about capacity all the time, yet they claim they can handle this just fine. I call bullsh*t. Feeding a tower with 8x T1 lines does not = 100mbps. Sure, you could do 3x DS3's, but that would get cost prohibitive.
..unless you plan to charge insane rates for these speeds. Like >$50,000/mo per school.

At our location we have over 250 users on a Atlantic Broadband connection as a primary with a Metro-E 20/20 pipe from Windstream as a failover.
We get 220Mbps/10Mbps for about $400 per month via a DOCSIS modem. I don't see why the schools can't do a similar design either when the majority of all traffic is mostly downstream. Now let's be fair that such speeds won't be available everywhere but I can bet it will be more cost effective than any T1 service currently running to it.
As for capacity, well it can always be built. However they always want to do it on someone else's dime.
Exactly. Here in CT, the state built some fancy fiber network to all the schools. It was a huge upgrade over our pair of bonded T1's serving several hundred computers, but I was wondering why they didn't keep the T1's as backup and call Comcast for Business Class service- it would have provided more than enough bandwidth for far less cost than the fancy fiber network...
All based on application, usage, requirements, etc, etc. The fiber network can provide them a more centralized environment. It could of been built not to provide internet but rather share resources across all schools within the state via internal hosted services. In short there own MAN/WAN. A PBX or Callmanager handling all calls between schools would save them thousands of dollars a year and require less DIDs since most people will have a internal extension anyway.
The school can simply reroute all WAN traffic at the local router via a different interface to a cable connection and throttle all traffic via a predetermined threshold. Burst traffic is also available when low utilization exists. Also school's pay a cheaper rate based on state pricing so if a T1 costs $400 a month chances are that the school is paying $200 per T1.
Maybe there was some master plan, although from what I saw, there wasn't anything great running over it, other than regular internet. Seems to me the costs of connecting schools via fiber was pretty high, when they could have all just called up their local cable companies and got business class service. Although they wouldn't have had the bandwidth to do stuff like centralized VOIP, they could still have accessed centralized state services and had remote management through VPNs and remote access over the public internet. My point wasn't about the cost of the T1's, but rather how slow they were. Up until the 2006 timeframe, the whole school was running off of a pair of bonded T1's, which was ridiculous. I think I had 6mbps for one house at home at the time. Comcast Business Class was 20 or 50mbps or something at the time.

The issue would be the head end (the other end of the VPN) had better have at least an OC3 to handle all the traffic from the schools.
3mbps x 50 schools = 150mbps.. and you know that the connections will probably be saturated at least 8 hours of the day.
No, I'm saying route internet traffic right to the internet, and only specific stuff that needs to be routed between schools between schools, and for remote administration, VPN into the school network, not the other way around.
