PROJECT NAME:

R&D on underlay-overlay cell arrangement for efficient use of the spectrum for mobile communications

COUNTRY OF ORIGIN AND CURRENT LOCATION:

Yokosuka-shi,Japan

PROJECT COORDINATOR:

Telecommunications Advancement Organizaiton of Japan

BRIEF OVERALL PROJECT SUMMARY:

As mobile communications including cellular phone and Personal Handyphone System (PHS) are showing rapid growth and becoming pervasive among users, spectrum management policy for development of the unused spectrum and effective use of the spectrum becomes critical issue. This project aims to develop underlay-overlay cell arrangement which is a new technology maxizing efficient use of the spectrum. The project aims at upgrading mobil communications through R&D efforts on this particular technology

PROJECT OBJECTIVES:

To promote efficient use of the spectrum for future mobile communications through R&D on underlay-overlay cell arrangement .

EXPECTED / ACTUAL RESULTS:

Realization of mobile communications with efficient use of the spectrum

PARTNERS /ACTORS IN THE PROJECT:

Telecommunications Advancement Organization of Japan

USE OF INFORMATION / TELEMATIC TECHNOLOGIES:

In order to establish underlay-overlay cell arrangement, items listed below will be covered by this R&D.
(1)Characteristics of radio propagation in the underlay-overlay cells arrangement
(2)Basic components of the technology of underlay-overlay cells arrangement such as hand-over communications control technology

BENEFITS TO THE INFORMATION SOCIETY:
