3 Experimental Work

A city like Dehradun has variation in the geographical terrain. The total valley area is fuzzy in nature with a combination of urban, semiurban, and greenery vegetation. RF propagation in this multipath environment is generally varied considerably due to irregular geographical terrain. The distribution of the building structure and its height also vary from one place to another and from one area to another. As a result of the irregularity, a precise propagation model is not suitably available. Although network operators have a well-advanced computer-aided propagation prediction tools, they too require terrain define factors. This lack of information in the prediction tool introduces impurities into the database and an inevitable error results. This equipment is a must in the planning of network and cellular implementation. After the deployment of the system, various radio values like verification, reduction of the interference reduction, and adjustments of handover parameters are carried out by means of an experimental survey.

Experimental work has been carried in the northwest part of Dehradun city. The area under test is in the outskirts of Dehradun city and is 10–15 km from the central location. The areas under observation are centrally located at Kandholi, Pondha, and Bhauwala of Dehradun. All the observations are measured up to 2.5 km because the population distribution is located within this range. Any two areas under observation are 5–6 km apart in distance.
