Frequency Bands & Channel Bandwidth | Telecoms Bytes - Mpirical 

What fantastic feedback! Thank you! Glad you found it helpful.

Thanks for your comment! Great to hear!

Thanks for you comment, we hope this helps answer your question: Each operator has several radio frequencies they can operate on, these are typically called “channels” and are given a “channel number” to identify the centre of each. As an example, in 5G, the NR-ARFCN (New Radio Absolute Radio Frequency Channel Number) is used to represent the channel number. Now this channel will be in a “frequency band”. These are areas of the radio spectrum that have been reserved for 2G-5G operation. To help with bands and channels think about a car FM radio, this operates on one band, however there are a number of channels (radio stations) which you can tune to within the band (a range of frequencies). Cellular networks are the same, there are a number of bands, typically known as: 700MHz, 900MHz, 1800MHz, 24GHz etc. In each of these bands there are a number of channels (like car radio stations). These channels may belong to the same or a different operator. The last concept is bandwidth, each channel can also have a bandwidth (typically 5MHz, 10MHz ,15MHz, 20MHz, 40MHz, 100MHz or more…the greater the bandwidth the greater the capacity and potential throughput! In summary, each operator will have access to specific channels (frequencies), which will be in a frequency band. Other operators may also exist in the same band; however, they would be utilizing a different channel (frequency).

Hi, thank you for your comment. The supported bands mentioned were “2.4, 5 and 6 Gigahertz”, the 5GHz band is just one example chosen to demonstrate the concept of channels and bandwidths.
