Übrigens zum Thema was globale LTE-Frequenzen werden: hier die Beschlüsse der ITU:
Globally harmonized spectrum identified for use by International Mobile Telecommunications (IMT) represents an important step in the worldwide development of IMT systems:
450−470 MHz band
698−862 MHz band in Region 2 and nine countries of Region 3
790−862 MHz band in Regions 1 and 3
2.3−2.4 GHz band
3.4−3.6 GHz band (no global allocation, but accepted by many countries)

Seit 2007 sind wohl noch das 900Mhz, das 1800 und das 2600Mhz-Band dazugekommen
