[Hidden-tech] WiredWest fiberoptic broadband

[Matthew S. Crocker]

Will,

 802.16 (aka WiMax) operates in the 10Ghz+ range
 802.16a operates in the 2-11Ghz range.

 WiMax is an ethernet framing technology over wireless that supports multiple providers sharing the same spectrum.  In a point to multipoint distribution network you'll probably use 2.4Ghz or 5.7Ghz and run into the same power limitations that comes with unlicensed wireless.  You'll also have the same competition to the spectrum from other non-wimax transmitters (cordless phones, baby monitors, alarm systems).   The higher the frequency the more line of site it becomes.

 You can build an unlicensed 2.4Ghz network that will push 100+mbps over 50+ miles today with off the shelf equipment.  That is a point to point scenario with large high gain antennas. That is not something you would deploy in a distribution network.

 Any IP capable network will handle 'video'.  Wireless won't handle the video required for a triple play.  1 HDTV channel takes 6.3mbps when compressed. With IPTV you multicast all of the channels in your backbone (1000 channels = 6.3 Gbps, 1 10GigE ).   For distribution of the video you use IGMP protocols from the set top box to tell the local 'node' switch to send a specific IPTV channel down the drop to the house.  So, you only need 7mbps per house to handle 1 video channel but 10GigE in the backbone.

 FTTH is *the* solution for a broadband connected community.  Everything else is a short term band-aid that will delay the true solution (fiber) and is a waste of money (IMHO).   

 If you figure a town with 20 miles of roads @ $50,000/mile for distribution you are looking at $1,000,000 build.   $1 Million over 20 years at 4% is $6k/month.  A municipality can get a 20 year bond @ 4%.  A business cannot.  A business would need an ROI in the 3-5 year timeframe $1M over 5 years @ 6% = $19k/month.

As a service provider I would need to spend $100k per town + $1k per home to bring in the proper electronics to light the fiber.  I would want 1 strand of fiber per house at an aggregation point in the town.  I would go straight to ActiveEthernet, 1Gbps, single strand bidirectional fibers.  Full GigE up and down.   At that point you can get your video from iTunes, NetFlix, Tivo, Hulu, YouTube, etc.    The days of broadcast TV are numbered anyway, I'm not sure I would spend $1M+ to build an IPTV headend.  

State build regional network,  town builds local network, home owner builds driveway network.

If there were money to be made building fiber in the hill towns it would have been done already...
