3GPP urges caution over IMT-Advanced promises

Source: Rethink Wireless
No fewer than six technologies have been submitted, seeking approval as official standards for IMT-Advanced, the next wave of wireless systems, which is designed finally to achieve 'true 4G' or gigabit stationary speeds (100Mbps mobile). Whereas a few years ago, few would have seen the need for such performance, now it seems operators can hardly wait to access the platforms that will let them support massive mobile broadband and multimedia usage, and while they may have years to wait for real 4G, they are increasing the momentum behind current technologies, LTE and WiMAX.

3GPP is achieving the goal of unifying the world behind a single cellular standard. This means that LTE and the Evolved Packet System (EPS) are applicable to an even wider set of deployment and migration scenarios than ever before.

At the September Plenary meetings, in Seville, Spain, Adrian Scrase - the Head of the 3GPP Mobile Competence Centre - interviewed each of the TSG Chairmen about the impact of this success on the way that they work and on the future of the Project.

* Service & Systems Aspects Chairman: Stephen Hayes
* GSM EDGE Radio Access Network Chairman: Andrew Howell
* Radio Access Network Chairman: Takehiro Nakamura
