ITU RA-12 initiates studies on mobile broadband


The 2012 Radiocommunication Assembly  organised by the International Telecommunication Union (ITU) concluded this year’s session with new directions in radiocommunications including initiating of a new studies on mobile broadband.

The week-long deliberation, ITRealms Online gathered holds every three to four years, while the Radiocommunication Assembly deliberated on the future direction of radiocommunications and reached significant decisions that will impact the future mostly in an increasingly wireless environment.

The Radiocommunication Assembly (RA-12) chaired by Mr. A.R. Jamieson of New Zealand, had over 500 participants from 102 countries in attendance the Assembly.

RA-12 approved a series of Recommendations and Resolutions that established the International Mobile Telecommunications (IMT)-Advanced technologies and initiated further studies for the development of global mobile broadband communications.

According to the Secretary-General, ITU, Dr. Hamadoun TourĂ©, the Radiocommunication Assembly, like the World Radiocommunication Conference represents an important landmark in the life of ITU’s Radiocommunication Sector.

This Assembly, he said, has once again demonstrated the central role that the Radiocommunication Sector plays in the global development of information and communication technologies.

Based on the new milestone in global mobile broadband, he said, the specifications for the next step in mobile broadband wireless technology – IMT-Advanced; were agreed by the Assembly.

He pointed out that with the completion of an intensive programme developed by ITU’s Radiocommunication Sector (ITU-R) to stimulate global development of the future IMT technologies.

He emphasised that following a detailed evaluation against stringent technical and operational criteria, ITU has determined that LTE-Advanced and WirelessMAN-Advanced should be accorded the official designation of IMT-Advanced.

He explained that IMT-Advanced systems include new capabilities that go beyond IMT-2000, widely deployed since 2000 and referred to as 3G mobile technology.

ITU, therefore, specified the standards for IMT-Advanced, the next step in global wireless broadband communications.

Stressing that IMT-Advanced provides comprehensive support for broadband wireless data and brings major improvements.

These, the Assembly outlined to include increased spectrum efficiency to handle more users at higher data rates per radio channel; a fully packet-based architecture for reduced costs; lower latency leading to more responsive Internet and multimedia applications.

Additionally, the Assembly underscored the fact that improved radio resource management and control would enhance quality of service, and new capabilities for the radio interface such as wideband radio channels and multiple-input and multiple-output  (MIMO) for the use of multiple antennas at both the transmitter and receiver-end to improve communication performance.

The RA-12 also decided to conduct further studies related to the development of a continuous time standard in order to address the concerns of countries that use the current system of the leap second in Coordinated Universal Time (UTC).

The decision, ITRealms Online gathered, was reached to ensure that all the technical options related to the issue are fully addressed, adding that these studies will involve further discussions within the ITU membership and with other organizations that have an interest in the matter related to the suppression of the leap second and will be referred to the next Radiocommunication Assembly and World Radiocommunication Conference scheduled for 2015.

Further, the Radiocommunication Assembly it was gathered planned for future technologies and based on the approved resolutions to focus studies on new radiocommunication techniques and applications, such as cognitive radio systems, and on the potential for radiocommunications to act as a catalyst to reduce the impact of human activity on the environment.

RA-12 also agreed on changes to streamline the working methods of the ITU Radiocommunication Sector in adopting recommendations and elected the chairmen and vice-chairmen of the Study Groups that will conduct the work in the next four years.

The Radiocommunication Assembly provides the necessary technical bases for the work of the World Radiocommunication Conferences, sets future work programmes on many technical issues of a worldwide character in the field of radiocommunications, and approves worldwide radiocommunication standards (ITU-R Recommendations).
