The EU opens the GSM band for 3G broadband technology The Council of Ministers has followed in the footsteps of the European Parliament and passed the proposal made by the European Commission to amend the so-called GSM DirecTIve regulations. The regulation was put forward in 1987 to open part of the 900MHz band for GSM mobile communications services, and the proposal to amend the regulation allows the 900MHz band to continue to be used for GSM services while also opening up to higher speeds such as mobile Internet access Pan-European communication service. EU Commissioner for Telecommunications Viviane Reding said that the amendment of GSM DirecTIve will lift restrictions for mobile operators, and therefore enable the construction of more advanced technologies in the GSM band to provide high-speed mobile broadband services; she expects this will inspire the European wireless economy , And gave birth to "Digital Europe". The European Commission proposed to share the wireless frequency band with other advanced technologies in November 2008. The first is 3G mobile broadband technology UMT; the proposal was approved by the European Parliament in May. Next, the revised regulations need to go through some approval procedures before they can be officially announced by the EU official. While passing the GSM DirecTIve amendment, the European Commission has also made a resolution that will set the technical rules for coexistence of GSM and UMT.
