The International Telecommunication Union (ITU) brought LTE and WiMAX one step closer to official 4G status at the close of a week-long meeting in Chongqing, China.

The ITU voted that LTE-Advanced met the criteria for IMT-Advanced technology, commonly referred to as 4G. Final ratification of LTE Release 10/LTE-Advanced will occur at an ITU meeting in November.

The 3GPP's LTE-Advanced standard supports up to 100 MHz, 8 x 8 MIMO on the downlink and offers peak data rates of 1 Gbps.

The ITU also voted that the WirelessMAN-Advanced portion of WiMAX IEEE 802.16m met the ITU's requirements for IMT-Advanced.

WirelessMAN-Advanced is a group of three proposals, two of which are technically identical to IEEE's 802.16m WiMAX standard. The ITU has accepted an offer from the groups behind the three proposals to have the IEEE complete and submit the full detailed specification of the technology at a meeting in April 2011.

The WiMAX Forum said it is working to complete its WiMAX Release 2 specifications, which will meet the ITU's standards for 4G and support both paired and unpaired spectrum bands.
