#3 even if you use yearly average temperature (which is a terrible metric), why would you put a 45F destination under the sunny category?

#3 is basically zero rating, which is another form of discrimination, a way for the ISP to play gatekeeper and favorites. We, as a society, do not want that. As to dynamic bandwidth offerings, there is no need for the content provider to pa

A lot of IP transit bandwidth is bought at a colo or an IXP, regardless of where the end customer is physically located. This is because it is usually more expensive to buy bandwidth directly from the local (monopoly) provider than to buy t

Yes, you can hang fiber, it's called aerial fiber.

> At the phone poles there are large devices (repeaters?) and I assume more equipment at the nearest colo. Fiber networks don't use repeaters out in the field. It may have been a (large) splice enclosure or some non-fiber equipment.

Partly/mostly. However, a lot of it has to do with the fact that they are (usually) the sole provider.

Just make sure you use an Internet connection that allows sharing. Residential connections can't be shared.

B4RN connects to the Internet backbones in Manchester, some 70 miles away. While it is possible in rural locations to do the same, rural locations do not have many access points, very few providers to select from and no Internet Exchanges.

It doesn't really make sense to run copper or coax anymore. Fiber is where it's at. It's not very hard if you do it on private property, but the difficulty level does go up if you have to use public right of way due to red ta

It would be great if this could be used in (new) mobile phones and tablets in a low power mode when you don't need high data rates.

That counterargument kind of assumes you can become a citizen wherever you want. A lot of people can't, even if they could afford to buy a house.

Yes, but that's hard to calculate. What you really want to calculate is linear density. My best approximation for this is people per mile of road. This is easy to calculate and this data is readily available. Sweden has 10 people per m

What you really are interested in is linear density. The only metric that matters when building a network is linear route miles of cable per subscriber needed to provide service. There is a single metric you can use to approximate this for

If you want to use a single metric, why not use people per mile of road? This correlates well with the only network metric that matters, linear route miles of cable per subscriber needed to provide service. Every (on-grid) dwelling and busi

I found this interesting. Too bad the prints are like $250/$500 each depending on whether they are monochrome or color. Wasn't easy to find out either, what with their expired webshop domains and all.

I agree with you that the nature of the problem in Australia is political, but not that the main root cause is corruption/collusion. The main problem is that the politicians made promises they cannot keep: cheap fiber to everyone at th

Bandwidth can be segmented off using multiple technologies. Basically you can either dedicate wavelengths per tenant (typically 96 wavelengths on a DWDM system) or dedicate lower bitrates per customer (for example 1 Gbps) and mux them toget

Google's problems in rolling out fiber is not with the equipment, it's in putting the actual cable on poles and in ducts. Buying Nokia would not help one bit with this.

The usable parts of infrared light (amplifiable C and L bands in single mode fiber) is about 10 Thz. According to Shannon's theorem the theoretical upper limit for symbol rate in a linear channel with 30db SNR is 10 bits/s/Hz
