Windows Phone Thoughts: Wireless Lamp Posts Everywhere

Look out your window and count how many lamp posts you see! That is the number of access points you might be surrounded with in the future, according to this article. "Computerised lamp posts look like being the basis of the biggest data network ever, as the world's traffic monitors set about controlling cars with wireless. ... It's a very simple concept. "Take a lamp post, put electronics in it, send messages to other wireless devices, including other lamp posts." You can link the lamp post to the Internet directly, if there's an internet connection available - any sort of connection at all will do. High speed fibre is best, but if that's not available, then a satellite, or maybe a phone line nearby can be used. And if there's nothing at all, then ask the next lamp post if it has any Internet connection. It may do. If it doesn't, the next one may do; and so you go along the road until you find one that does. It takes fractions of a second to complete the chain; and once the chain is complete, any data you like can be sent down it."

The article continues to explain how this concept is seriously planned in the UK. I think it sounds very exciting and would not mind to live in a community where Wi-Fi was everywhere as long as a lamp post was in sight. However, I guess I can think of four issues:
1. Monopoly. It will be critical to make sure the infrastructure is open for any operator that wishes to sell connectivity. Otherwise, the price will surely be the doom of this idea.
2. Upgradeability. New wireless connectivity hardware, software and protocols are pushed faster than ever. How do you make sure hundreds of thousands lamp posts are easy to manage and upgrade?
3. 3G. Is Wi-Fi enabled lamp posts everywhere + Voice over IP a nightmare for 3G operators?
4. Health. One 3G base station can cause a riot, over health issues, in many cities in Sweden. How do you sell: "every lamp post is an antenna"?
