5G NR the layer 1 radio access specification, just like LTE, GSM, etc. It is defined in 3GPP spec series 38. https://www.3gpp.org/DynaReport/38-series.htm On Fri, Jan 17, 2020 at 2:34 PM Alexandre Petrescu < alexandre.petre...@gmail.com> wrote: > Mark, Shane, > > I do agree that listing a 3.5 GHz band of frequencies does not > necessarily mean it's 5G. > > Bu I would like to further clarify, if you permit: > > 1.
