-Shades up so other planes can see you better while you are on the ground at night

I haven't heard this reason before, and if you think about it, dedicated freighters don't have passenger windows at all for light to escape through.

One explanation that I have heard is that having the shades open provides better situational awareness during the critical landing and takeoff phases of fight. Suppose the port side engine catches fire. With the shades open, people will see this and the flight attendants will know to direct passengers to evacuate using the starboard side exits only.

Your airplane contained a microcell and wifi base station. This reduces the transmitter power concerns because the mobile unit is able to reduce power because it's close to the base station. It also resolves the problem of a phone being present in many ground cells at once, since the mobile unit instead connects to the aircraft-based cell.

The most popular provider of inflight wifi in the US is Gogo, which uses a ground-based network of CDMA transmitters to link the aircraft's wifi base station with the Internet.

They'll stay in business because the discount carriers don't offer good phones. Yes, Virgin Mobile has several Android smartphones, but they're not particularly good ones. No Samsung Galaxy or Droid Razr or HTC Evo phones there, instead you get phones like the LG Optimus V or Motorola Triumph or HTC Wildfire S. On some of their phones, they even denote that they come with Android 2.2 as a feature!

Cellphones are an interesting case because having redundant infrastructure isn't quite the eyesore that it is for power and landline phone companies. So its easier to have competition at the physical layer. You still have multiple cell towers, but those aren't be running down every street the way wire-based services do. There's still the spectrum problem, though.

Sounds like the big problem is the link to the nodes is too small for the number of homes. They need to reduce the number of homes off each node even more, or get bigger pipes to each node. Probably both.

As another reply points out, Verizon FIOS does run fiber to each home. AT&T U-Verse is even closer to Cox's architecture in that it's fiber to the node, then copper to the home.

AT&T was also able to reduce the total bandwidth need by building the U-Verse TV network as an IPTV service. Each channel is a separate multicast stream, resulting in the link to the home only having to carry the channels currently being watched/recorded by the customer, rather than having to hold all channels simultaneously as conventional cable TV systems.

As a cable TV provider, Comcast is supposed to be a regulated monopoly. And there's a reason for that, and it's the physical layer.

In most areas, you have one electric company, one phone company, and one cable TV company. That's because each provider has to run their own wires, and a hundred years ago, city leaders didn't want to have all the separate wires running everywhere if each electric company, for example, had to have their own power lines to serve their own customers. To avoid this, they granted a monopoly to a single company, but it's a regulated monopoly -- the rates they charge to customers are controlled by the government; if they want to raise rates, they have to ask for and get approval.

Nowadays, things are a little different in that there are sometimes requirements for the company that built and owns the physical layer to allow other companies to provide end-user service. But since the company that owns the physical layer competes for end users with companies that rely on them to provide the service, there's often not a financial advantage to the end user to use a different company. Regulation would have to force the owner of the physical layer to provide pricing that would allow third party competition.

Internet access is kind of interesting in that essentially the same product can be provided over different physical layers: The cable TV network, the wireline telephone network, satellites, and the cellular telephone networks. The biggest two providers of residential high speed services are the cable TV and wireline phone networks, which have regulated monopoly status due to the historical issues I described above.

Now there is an alternative that's popped up in a few places, such as Ashland, Oregon. In Ashland's case, the city itself built a high speed fiber network throughout the city. But the city itself isn't a content or access provider. Instead, third party companies can compete to offer Internet access through the fiber network. I'm not sure how the cable TV side works, but I know that cable TV comes over the fiber network as well. In that case, all the access providers compete fairly, since the owner of the physical layer doesn't compete with them. Potential issues with this is that the cost to build and maintain the network comes out of taxpayer dollars, so people who choose not to use the service are still paying for it. And in other cases where local government has attempted to build it's own network infrastructure, the existing providers have complained quite loudly.

Comment Re:Is a six hour flight short? (Score 1) 78

Hawaiian has two distinct types of flights: The very short inter-island flights that max out around 40-45 minutes (Honolulu-Hilo), and the Trans-Pacific flights to the west coast (and soon New York) and international destinations that start at around 4.5 hours (Honolulu-San Francisco).

The inter-island network has pretty high on-time reliability, but problems can have a big impact. With the number of flights an aircraft performs each day, a significant delay early in the morning can cause delays on several other flights throughout the day that that particular aircraft is scheduled to fly (referred to in the industry as a "line of flying").

The Trans-Pacific network is more delay prone, but since it's a fewer number of flights overall, it's impact on percentage based statistics is less. Most of Hawaiian's Trans-Pacific fleet will start the morning in a west coast city, fly to Honolulu, then turn around and fly back to the west coast and spend the night (I haven't looked closely at the international schedule to see how that works in the scheduling). A late arrival on the west coast can delay the following morning's flight if the same crew is due to fly back to Honolulu, in order to allow the crew to meet their rest requirements.
