Comment: Short and straight only? (Score 1) 1

I'm having a hard time seeing any communication use for this. Surely the range is going to be very limited and it can only fire in a straight line. If that's the case I'm not sure what the benefit is over just firing a laser straight at the receiver.
Air does have a lower refractive index than glass which has latency benefits, but 'Hollow Core' fiber is in development which would provide the lower latency without requiring line of sight.

It's true a lot of FTTH early adopters didn't find the business model as attractive as they thought. But every year the price of the FTTH PON equipent comes down, and the price of ADSL and copper is going up.
It's inevitable that we will all have FTTH at some point. It's debatable whether the existing ILEC will survive long enough to build all the way to the home, but I think the healthier ones will.

20 milliseconds to what? Google? That's going to be dependent entirely on the ISPs transport network and peering locations, and the access technology won't affect it at all (assuming it's not congested).
The latency from the customer to the broadband gateway router in the ISPs office is going to be similar to a LAN.

The other concern is, what if only 1 or 2 tenants in the 10 story office building are interested in anything higher than 50mb/s service. Why run fiber through the whole building for those two customers, when you can just upgrade your equipment in the wire closet and be done in an afternoon?

This is the future of DSL land. Every year the twisted-pair based providers build more fiber extending their DSL aggregation modules closer to the customer. Eventually they will all become FTTH providers, but somewhere in-between they are high speed DSL over short copper lines that go to a DSLAM at the end of the street.

Is this a republicans vs democrats thread in disguise? Just because one side of the discussion is arrogant doesn't mean the other is not. Google has a long history of failed projects because they're not afraid to over promise and blindly charge into a project. I think the ignition recall is a good illustration that the automotive industry doesn't have that luxury. My Google TV appliance, which is now an abandoned project, isn't going to kill me. An abandoned self driving car project might, even if it's not my car.

So better performance and lower costs are not a benefit to the ISP and its customers? I'm not speculating here, just yesterday we deferred a project costing $300,000 because installing a Netflix OpenConnect cache dropped our peak bandwidth usage enough in the market in question that we can afford to wait. Now we can wait a few months, maybe to 2015 and spend that money on other projects.
