IMT advances 4G mobile wireless broadband

New International Telecommunication Union (ITU) radio interface standards to revolutionize mobile communication, has announced the receipt of six candidate technology submissions for the global 4G mobile wireless broadband technology known as IMT-Advanced, report REMMY NWEKE & CHARLES OKOH.

Chief, Media Relations and Public Information at ITU, Mr. Sanjay Acharya said that the selected technologies are expected to be accorded the official designation of IMT-Advanced - to qualify as true 4G technologies by October 2010. The submissions were made in Dresden, Germany at the meeting of ITU’s Radiocommunication Sector (ITU-R) Working Party 5D in response to an open invitation in March 2008.

The meeting was held 14-21 October 2009.The six proposals aligned around the 3GPP LTE Release 10 and beyond (LTE-Advanced) technology and the IEEE 802.16m technology, will be assessed against ITU-R requirements using a defined evaluation process.

This rigorous assessment over the next year will be supported by the work of independent external evaluation groups that have been established around the world and will take place under the direction of ITU-R Working Party 5D. In conjunction with the Dresden meeting, the third Workshop on IMT-Advanced provided an opportunity to technology proponents and evaluation groups to interact.

As a jump-start to the assessment phase, fourteen evaluation groups registered with ITU-R, representing the whole gamut of stakeholders, including equipment manufacturers, technology developers, network operators and service providers, market and user organizations, universities, research institutions and national administrations.

He quoted the ITU Secretary-General, Dr. Hamadoun Touré, expressed her appreciation for this worldwide effort.

“We note with excitement that the technology developments in wireless communication continue to expand their reach and application to enrich the lives of people around the world,” Touré said. “ITU has a rich history of more than 25 years in coordinating and advancing global broadband multimedia international mobile telecommunications systems.

IMT-Advanced continues this tradition by not only leading with a strategic vision, but also in translating the vision into practical reality in this challenging ICT environment.”

Equally speaking, Director of ITU Radiocommunication Bureau, Mr. Valery Timofeev, congratulated all the players from government, regulators and industry who have been actively involved in the evaluation process of IMT-Advanced for successfully reaching this important milestone in the choice of radio interface technology.

Stephen Blust, Director of Radio Standards, AT&T and Chairman of Working Party 5D, offers this viewpoint: “In 2002 when the strategic vision for 4G - which we designated as IMT-Advanced - was laid out in anticipation of the longer term future needs of the marketplace, it established a new level of expectation for the capabilities and performance of global mobile wireless broadband systems that many thought at the time was something that could not be reached in this decade.

When ITU-R established the detailed performance requirements of IMT-Advanced in 2008, it truly raised the bar for mobile wireless. It is gratifying to note that the stakeholders in the mobile wireless industry have risen to the challenge.

And we have every expectation that with these proposals the vision can indeed be achieved in the near term.”The close partnership between the ITU-R members and the global wireless industry in the work on IMT-Advanced builds upon the success of the ITU-defined IMT-2000 system (3G) that continues to be enhanced following the demands of the marketplace.
