The new specification will enable the use of millimeter wave spectrum, which has the potential to increase data transfer rates by up to 100 times compared to current 4G networks.

A fresh viewpoint: ITU Radio Regulations

Spectrum Allocation is a crucial aspect of Regulation and Spectrum. The bands identified by WARC-92 are shared with other radiocommunication systems and services.

These shared bands are used differently in various countries, which can lead to confusion and challenges in implementation. The traffic and service mix carried by IMT-2000 networks may vary from country to country, and even within countries.

IMT-2000 will initially only need portions of these shared bands, but the use will grow with time. The world wide frequency bands 1980-2010 and 2170-2200MHz were scheduled by WARC-92 for the Mobile Satellite Service in 2005.

However, these bands are intended to accommodate the satellite component of IMT-2000, which would need to be available around the year 2000 to allow for the introduction of the satellite component at the same time as the terrestrial component.

Here's a summary of the key points regarding spectrum allocation:

The IMT-2000 network architecture is designed to be flexible and adaptable, allowing for seamless interaction with other networks and services. This is made possible through the use of advanced technologies such as Software Radios, which enable the network to be updated and modified dynamically.
