Radio planning

Sumatronic provides computer based simulations for radio propagations for direct and indirect signal paths and delay-spread analysis for your needs. The very precise digital elevation-model in 20 x 20 meter pattern is the basis to perform calculations. Thanks to our in-house radio-planning system we can offer express deliveries or interactive simulation-session together with the customer.

For our calculations we use a full "deterministic" simulation-system with 3D-culculation. Besides direct wave path, reflections and diffusions are also recognised. Therefore we can offer you services, such as simulation and planning. Thanks to our pre checks, you can avoid bad investment when choosing a wrong transmitter site. This saves you money and your precious time.

 

Especially in hilly regions there are some unpredictable surprises. It is not seldom, that a transmitter which produces enough field strength fails quality targets due to reflection of the waves due to steep rocks, water surfaces of lakes or snow covered ambiences. Often the quality of the reception is significantly reduced because of such effects. When analogue transmission is in use, such as FM-broadcasting, such disturbances can easily be recognised as stirring noise (especially when stereo reception is used) and the strong disturbing sway of reception level can easily be recognised. When digital systems are in use such as GSM-mobile telephone, DAB, DVB etc. the reception can give high bit-fault rate, which reduces the subjective quality of the reception, or might even cut the connection. Sole Reception level measurements have almost no value to effective utility to provide good general reception of an area

 

The right design and the optimal site-location of the transmitter and the testing with measures equipment will guarantee, that the investment will meet most of all expectation of the customer.
