Early 5G Speeds Do Not Mean Much

Unlike 3G and 4G, 5G networks will use an almost-bewildering range of different frequencies, including low-band, mid-band and millimeter wave spectrum. That also means it will be nearly meaningless to compare 5G speeds, unless one knows both the frequencies and channel sizes supporting 5G. 

Speed hinges on bandwidth; bandwidth hinges on channel width and frequency. Channels are smaller at low frequencies, much wider at high frequencies. Beyond that, the full range of 5G frequencies available to any single service provider  have not yet been deployed. Nor, for that matter, have the full range of new technologies to boost effective bandwidth been deployed. 


It is not that the test procedures are faulty, simply that 5G remains in early launch stage, while the potential bandwidth increases over 4G will vary, from place to place, based on the actual frequencies used to support the 5G networks.
