Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and
Systems (SES).
The present document is part 3, sub-part 9 of a multi-part deliverable. Full details of the entire series can be found in
ETSI TS 102 744-1-1 [10].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and

Introduction
This multi-part deliverable (Release 1) defines a satellite radio interface that provides UMTS services to users of mobile
terminals via geostationary (GEO) satellites in the frequency range 1 518,000 MHz to 1 559,000 MHz (downlink) and
1 626,500 MHz to 1 660,500 MHz and 1 668,000 MHz to 1 675,000 MHz (uplink).
