Below is a comprehensive overview of mobile frequency band assignments listed by country.

Cellular networks operate on different frequency bands including the 450 MHz band, 700 MHz band, 800 MHz band, 900 MHz band, 1800 MHz band, 2100 MHz band, and 2600 MHz band. Administrations typically issue "frequency band management rights" rather than individual licences per base station. Mobile operators can thus manage and monitor the awarded spectrum themselves. A growing number of Administrations allow carriers to decide which wireless standard to deploy (e.g. GSM, CDMA, UMTS, LTE or a combination of cellular technologies). This modern spectrum management concept poses new challenges to spectrum monitoring. How to measure frequency occupancy, spectrum efficiency, licence compliance or spectrum interference?
