BR- Biennial seminar on SMS 30 October 3 November 2006

1

Main Functions of SMS4DC Administrative Functions Relational database management; Recording frequency application, frequency assignment, licensing, coordination data, import data from BRIFIC & SRS producing electronic notices, print license, invoice & spectrum fee Security features: Multi level access enables system administrator to define users and groups with different access levels.


2

Main Functions of SMS4DC Engineering Analysis Function Enhanced analysis tools for frequency arrangement, assignment, coordination and interference calculation Propagation models based on ITU-R latest recommendations available at the time of development, i.e. P.1546, P.370, P.530, P.452, P.526, Extended HATA models for various service types and P.618-8 for Earth to space total attenuation calculation; Coverage area, field strength, field strength contour, Microwave link calculations, Microwave link availability, network coverage and best server calculation.


3

Main Functions of SMS4DC Geographic Map Display Function

User friendly interface, displaying of Digital Terrain Model, capability of importing standard mapping formats including Globe map and displaying of geographical maps, Online latitude, longitude and altitude presentation, overlaying, Scrolling and Zooming functionality capability of handling vectors, Providing multiple entry functions, menu items, Assigning new stations on map and Searching and displaying a station or group of stations on map.BR- Biennial seminar on SMS 30 October 3 November 2006 4
