In telecommunications, spectrum is often used to refer to radio frequency bands used to carry services, especially in discussions of frequency allocations for specific standards or service providers.
For example, mobile operators are preparing to bid on recently released spectrum freed up by the phasing out of analogue television signals in the 800MHz and 2.6GHz bands.These will be used for the delivery of future mobile broadband services.
The limited amount of suitable spectrum available means there are many regulatory issues regarding how it should be allocated.
