Abstract:
This paper provides a survey on the available unlicensed spectrum bands for cellular mobile networks. Unlicensed spectrum bands in both the sub-7 GHz, including 2.4 GHz, 5 GHz, and 6 GHz, as well as millimeter-wave, including 60 GHz, for the current and future mobile networks, are discussed. Major aspects of each unlicensed band, notably operational region, regulatory requirement, existing technology, available bandwidth, spectrum range, benefit, and challenge are surveyed. A comparative framework, including these above aspects, is then developed in a tabular form to find an appropriate unlicensed spectrum band corresponding to each aspect. Finally, we point out the major benefits and challenges of operating cellular mobile networks on unlicensed bands.
