Which 5G bands specifically are used? Wikipedia suggests, that 1700 MHz is used by bands n66 and n86; 2100 MHz is used by bands n1, n34, n65, n66, n84 and n95; and 700 MHz is used by bands n12, n13, n14, n28, n29, n67, n83 and n85.
For example, according to this map (which sadly doesn't contain 5G information for Videotron - hence my question), Videotron's towers seem to broadcast LTE on bands 4 and 66, both at 1700 MHz - but not on band 70, which is also at 1700 MHz. As such, a phone which receives data at 1700 MHz on only band 70 and not on bands 4 and 66 would not function on Videotron's network.
Hi! Currently, our only 5G bands are 2100 and 1700mhz. We are working on 700mhz coverage.
As for LTE: we have 2100, 1700 (AWS Band 4) and 700mhz (Band 12). We share our network with a partner that offers 850mhz and 1900mhz (bands 2 and 5).
Hope this helps!
