Let's take a look at a simple example of using UNIX commands in the classroom. When it comes to the specific interactions between teacher and student in the state of Alaska, then you are probably talking about Apple computers. Lots of companies make management tools like this: SMART Technologies, SourceForge, and CognitiveEdge to name a few.
With simple tools like Apple Remote Desktop available, I think every teacher who interacts with student computers should have a tool to manage their classroom. If I had to choose one area to which every school district is deficient across Alaska, I would say it is student workstation management. I have been in the Bush and working with Apple computers since 2006. That's pretty amazing in itself, rght?! The real question here is how fast is a microwave transmission. The server on the other end sends you back a signal in the same way and you enjoy the webpage or action expected. You click a link and send a signal to an orbiting satellite, floating around the planet, then bounce it to Eagle River, AK which receives the signal and passes it on to the rest of the world. Transmitting a signal across a nearly line-of-sight is nothing compared to two trips through the atmosphere. Yes, in a way, but no, resoundingly, they are not the same. "But if the fiber ring is dependent on microwave transmitters/receivers, aren't those just physical dishes, just like the satellite systems of other ISPs?" The microwave towers and fiber are extremely reliable. The backbone is still up though 99% of the time. We are experiencing a failure in the delivery of the service from the mainline to our home via cellular transmission towers. This is not a break in the service to the village, though. Our signal drops, the access goes down, and sometimes even the transmitter/tower in town needs replacement. Many villagers, myself included, are residential customers of this service. This terrestrial system is limited by the weakest point in the ring, which I am often asked about as well. We're measuring in milliseconds here, so don't go crazy just thinking of the numbers.
The alternative is generally closer to 30-60ms. How much faster? Well the ISP for LYSD currently the has a 1000-1900ms latency, or time from one village to Anchorage (and the outside world) and back.
This system produces a signal more reliable, less dependent on weather, and with a faster connection. So if satellites are so bad, why not try something else? Alaska did just that: they ran a fiberoptic ring around the state and where they couldn't run cable they linked microwave towers. This was an example of jitters, or an unexplained drop in the connection, one that didn't even register with Pandora, but caused your Skype to go offline for a second and error your download. An example of this follows the earlier one except your download times out even though Pandora was streaming the whole time.
