Global Mobile Spectrum Assignments

When I recently wanted to find out which network operators have which and how much spectrum assigned in a country I found an incredibly cool website that has up to date information on this topic. Have a look over at spectrummonitoring.com! Not included in the charts is the US, probably because in this part of the world spectrum assignments vary quite significantly even between cities. But for Europe, Asia and the Americas a huge number of countries are present on the site.
