The Pakistan Table of Frequency Allocations is the broadest level technical document showing the allocation of bands to various types of services. It is a bit like a town plan subdividing land into zones. As well as giving the first layer of spectrum resource allocation, there is a degree of interference avoidance built into the service allocation relationships and associated regulations.
The Pakistan Table of Frequency Allocations is drawn from, and kept current with, the ITU Radio Regulations, which are revised every few years at World Radiocommunication Conferences.
The Pakistan Table of Frequency Allocations is the first planning document that should be consulted regarding spectrum arrangements in Pakistan. However, it is just the starting point and is not usually sufficient for assigning specific frequencies to users for frequency co-ordination, two lower levels of planning are usually necessary as described below.
