The European Commission on Monday put out a ruling (PDF) ordering that EU member countries had to open up the 900MHz and 1,800MHz bands for 4G mobile data. The decision would require allowing carriers to use LTE and WiMAX on the existing frequencies before the end of the year. The faster speeds aren't expected to clash with GSM, HSPA, or other 2G and 3G technologies that already use the airspace.
