1. IMO the only way you can build this for $100/unit is to use 2nd hand
stuff, which will never last the planned 5 years. Using openwrt and an
external aerial will allow you to create a mesh for a fraction of this
cost. See what the cost is for buying them in bulk.
Each node has 3 antenna/transmitters.
Agree that some machines will fail before 5 years, but even over 1 year the
costing is still heaps cheaper than dsl over a phone line at current market
costs.
2. Your 54mbit network is shared by how many people... even if it could
deliver the stated 54mbit, which it can't.
My ADSL connection gives me a dedicated 3.5mbit.
Sorry, not well explained...
Each node is interconnected by wire and wireless, each node spans no more
than 100m. My projetion is that each node is only sharing to 10 house
holds.
The network is initially supplied with a 10mbit feed which can be upgraded.
3. 3GB internet access for the whole network? Me and my immediate
neighbours use most of my 10GB each month.
No, 3GB for each user/household
4. Where's the costings for the electricity used?
There isn't one.
5. Backup/replacement hardware
There isn't on.
6. SIP?
iTalk
Tell you what. There's a proper sector array here at
http://www.trademe.co.nz/Computers/Networking-modems/Wireless-networking/auction-64027324.htm
for $1500. Cost out the savings there.
Or the start of a mesh network for $800 at
http://www.trademe.co.nz/Computers/Networking-modems/Wireless-networking/auction-64362848.htm
if you want to do down that path.
Or, it you want future compatability, look at using soekris or similar
hardware that uses mini-pci / pci units. They'll cost out well, and
weatherproof better ( POE? ).
Agreed. When the price comes down and the equipment has the right features
on it... thou I'd like to look at getting something made here in
Christchurch and export it to the world.
