why can't the UN just cooperate and use the same spectrum plan world wide?

Well the ITU (which is now incorporated inside the UN but around a long time before the UN) do carry out international spectrum planning. It is up to countries to decide what is best in their interests eg political, technical reasons however. Every 4 years, they get together in Geneva to sit down and work through issues and they try to be consensus based to allow for harmonisation for equipment supply and so on.

For a serious answer, Band 3 LTE is becoming more and more common worldwide.

Band 28 APAC will become a standard in the Asia Pacific.

And qualcomm/other companies are coming out with chipsets that support more and more bands.

See here for a list:

Using a single band worldwide simply is simply impossible.

There are standards set by the ITU and the 700 US, 700 APAC, 850, 900, 1800 and 2600 will be the key global LTE frequencies with 1800 on it's way to being the most adopted frequency everywhere except North and South America where this band isn't used for mobile.

There is no single band that has enough spectrum for multiple carriers to build out large scale networks. 700 is also a bad frequency in the same ways 850 and 900 are great for mobile but also very bad for network planning. In an era where network capacity and bandwidth requiements are rising you actually want areas where signals that don't travel long distances so building networks with higher frequencies makes lots of sense.

What are the average speeds people are getting with LTE? is it 100mb/s or is it less?

It will depend on device as well as many devices are CAT3 and network is CAT4 and latency is lower on 4G

To the Vodafone Speedtest server (so testing the OTA speed only, not the "Internet speed") I'm getting an average of 80Mb/s with my Galaxy Note 2.

That's not a bad average considering it's maximum speed is 100Mb/s.

Not sure but I think 150mb/s is LTE advanced

Vodafone running Cat4 = 150/50
But some devices will only be Cat3 = 100/50
