The process of uniform allocation of frequency bands across an entire region is called as Spectrum Harmonization. At the global level it is the ITU which facilitates the harmonization of frequency bands by the three regions that the world is divided in to. Allocations made by ITU are further coordinated by the regulators and at times the Governments of neighboring countries also facilitate the process. Spectrum Harmonization is a complex and vast field which requires deliberations and planning to fully reap the benefits offered by it. Countries with harmonized band plans benefit and those lacking it suffer adversely for years. This is because if band plans are auctioned without prior planning for harmonization and implemented then various issues arise, the most damaging of which is the cross border interference, which is harmful for the neighboring countries. A harmonized spectrum plan will benefit the region immensely specially for socio economic development and will offer more advantages to the whole region. This also ensures good services for the users and good growth chances for the operators.
While writing about the Spectrum Harmonization it is important to highlight that here we are talking about FDD frequency band plans, that is separate Uplink and Downlink frequency band plans. Because predominantly the world over FDD is being used and so here in the context of Pakistan and its neighbors we are also cite examples of issues arising out of these assignments.
