Europe Opens More Spectrum for 3G Mobile Jul 30, 2009
Under the GSM Directive of 1987, which harmonised spectrum use across Europe so mobile-phone services could take off, part of the 900MHz frequency band was reserved for 2G voice and text services. This band is at a much lower frequency than the current European 3G bands between 1,900MHz and 2,170MHz, giving it superior propagation and building-penetration properties, and making it cheaper to cover a given area, although not a given number of users, from a base station.
