Spectrum planning is the process of designing the allocation and management of the radio frequency spectrum to meet the needs of wireless services while limiting interference and enabling efficient use of the resource.

At the international level, the ITU-R Radio Regulations establish the framework and table of allocations that designate which services may operate in specific bands. Regional and national regulators implement these allocations, issue licenses, and monitor compliance.

Frequency bands are allocated for categories like broadcasting, mobile/IMT, fixed, satellite, and public safety. Within allocations, licenses can be primary or secondary, and operators must respect coordination requirements and guard bands to avoid harmful interference.

A typical spectrum plan starts with demand forecasting and a survey of current usage, followed by engineering analysis to identify available spectrum, potential interference, and harmonization opportunities. The plan leads to licensing: competitive auctions or administrative grants, with conditions such as power limits, technical parameters, and service obligations. Ongoing monitoring, enforcement, and periodic refarming updates ensure the plan remains usable as technology evolves.

Dynamic spectrum sharing, spectrum auctions, and technology-neutral licensing are increasingly common.

Global coordination is essential for cross-border services; balancing incumbents and new entrants; preparing for 5G, IoT, and future 6G; ensuring spectrum for public safety; balancing national security and privacy. Harmonized spectrum fosters equipment availability and global roaming; inefficient planning can constrain services and raise costs.
