This Recommendation provides information on coordination of the fixed service with mobile-satellite andradiodetermination-satellite service systems operating in the 2 483.5-2 500 MHz frequency band. Anestimation of the level of interference that may be caused by mobile-satellite and radiodetermination-satelliteservice systems is included. This Recommendation examines the impact of the relaxation of the powerflux-density level that triggers coordination with the fixed service that was agreed at WRC-12 under agendaitem 1.18.
Methodology and technical example to assist coordination of the mobile-satellite service and the radiodetermination-satellite service with the fixed service based on the power flux-density coordination trigger levels in the 2 483.5-2 500 MHz band
Recommendation ITU-T Z.161.1 defines the "continuous signal support" package of TTCN 3. TTCN 3 can be used for the specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protocol testing (including mobile and Internet protocols), service testing (including supplementary services), module testing, testing of CommonObject Request Broker Architecture (CORBA) based platforms, testing of application programming interfaces (APIs), etc. TTCN 3 is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustness, regression, system and integration testing. The specification of test suites for physical layer protocols is outside the scope of this Recommendation.
