There are many consumers who are unhappy with the fact that their 5G smartphone supports less than five or, on certain occasions, a single 5G band. For the unaware, 5G services would be rolled out using a dynamic range of the spectrum, which would for the first time include mobile services rollout with C-band spectrum (3.3-3.6 GHz) and mmWave (26 GHz and 28 GHz) spectrum band. 5G speeds and use cases would differ with respect to the particular spectrum band that is being used by the operator to provide services.  

For example, the mmWave band 5G would be able to deliver download speeds of up to 4.2 Gbps (proven by Vodafone Idea 5G trials) while using the C-band spectrum, download speeds of up to 1.5 Gbps can be delivered.
