Refarming refers to the repurposing of assigned frequency bands, such as those used for 2G mobile services (using GSM technology) for newer technologies, including third-generation (UMTS technology) and fourthgeneration (LTE technology) mobile services.
Spectrum allocations for IMT are technology-neutral. IMT technologies including GPRS, EDGE, UMTS, HSPA, LTE and WiMAX are standardised for technical coexistence.
