Abstract
In the bandwidth demanding world, TV white space is becoming one of the promising options. Its use as a secondary system with incumbent system must be managed in order not affect the primary users. This can be done by determining first the incumbent coverage and then the spatial variation that should be kept in order to maintain unaffecting region. Our primary concern is keeping the incumbent users safe. This is accompanied by different methods to keep the secondary device non interfering. The interference can be avoided by efficient cognitive radio technique or spatial variation between the two systems. The later technique requires efficient signal modeling and planning. The secondary system should be deployed in an area that is out of primary coverage. This is done by first determining the incumbent coverage. To determine this coverage, different factors must be taken in to account. Frequency and antenna height are of the significant factors. After the signal range of primary transmission with receivable quality is determined, we have determined another reserved distance that a secondary device should be kept away in its active status, without affecting the incumbent system. This is what is known to be reserved distance. From the significant factors in determining the spatial variations, we have found transmitter antenna height to be the most significant factor in white space system planning.
