TRANSMISSION SYSTEMS

Introduction To Transmission Systems
•        Transmission systems form the backbone of any networks.
•        Normally transmission systems include SDH, PDH, ATM, Microwaves, leased lines.
•        In GSM normally the core network is located in the same premises and are mostly interconnected by fixed wireline. In huge network consisting of many MSC located at different places the interconnection may be through any of the transmission systems mentioned above.
•        The Access network consists of BSC’s with many BTS’s connected to them in various transmission topologies. Normal practice is to connect various BSC’c to the MSC via fiber and different BTS’s connected to BSC via microwave in Daisy chain, star or any other topology. However there can be many different ways of implementation.

3G RF Planning Procedure & Radio Wave propagation

RF PLANNING PROCEDURE

Propagation tool setup
•        Set up the planning tool hardware. This includes the  server and or clients which may be UNIX based.
•        Setup the plotter and printer to be used.
Terrain, Clutter, Vector data acquisition and setup                                                                                  Procure the terrain, clutter and vector data in the required resolution. Setup these data on the planning tool. Test to see if they are displayed properly and printed correctly on the plotter.
Setup site tracking database
This is done using Project management or site management databases.This is the central database which is used by all relevant department, viz. RF, Site acquisition, Power, Civil engineering etc, and avoids data mismatch.
