11. 11 GSM HSCSD GPRS EDGE Enhanced EDGE Evolution of Radio Access Technologies WCDMA HSUPA EHSPA LTE | | HSPA | HSDPA The performance of EDGE technology is (watch out, implicit pun coming) on the boundary between 2G and 3G as defined by ITU’s IMT-2000 concept. In some markets, this has led to confusion over whether operators with 2G-only licences can run EDGE on their network. | | | | UTRAN | | | | | | | GERAN | | |

12. 12 Common frequency bands - GERAN GSM owes its early success at least in part to an agreement that all CEPT member countries should allocate the same frequency bands to the GSM service. GSM’s slow start in North America was in part due to the unavailability of the European GSM frequencies in the USA and Canada. 900 MHz 1800 MHz 850 MHz 1900 MHz Over the Releases, the GSM standards have been extended to include other bands for use in particular markets (particular countries, specialist applications). 700 MHz 450 MHz 410 MHz 810 MHz … Quad-band mobile terminals are commonly available, and are usable in most territories of the world.

13. 13 Common frequency bands - UTRAN WRC allocated common frequencies for UTRA on a world-wide basis. Further bands have subsequently been allocated on a regional basis. (See table on next slide.) 2100 MHz 2600 MHz 1900 MHz 1700/2100 MHz 1700 MHz 1800 MHz 900 MHz 850 MHz … As 3G takes over from 2G, so the 2G bands can be used for 3G service. 700 MHz 450 MHz 410 MHz 810 MHz … Multi-RAT mobile terminals are commonly available, typically supporting GERAN (GSM/GPRS/EDGE) and UTRAN.
