The International Telecommunications Union, which is the United Nations agency for IT and telecoms, has confirmed the specifications for next-generation mobile technologies. This will be known as IMT-Advanced and will include ‘LTE-Advanced’ and ‘WirelessMAN-Advanced’ (which is also known as Mobile WiMAX Release 2).
Although WiMAX, LTE and HSPA+ are often described as a ‘4G’ service, the ITU sees IMT-Advanced as being the true fourth-generation evolution.
