I see that another user asked for a list of inaccuracies on this page. A few that I noticed:


* China Mobile never used UMTS/HSPA. TD-SCDMA is a separate standard, and is not the same thing as TD-HSDPA or UMTS. They created TD-SCDMA in the first place because they didn't want to pay licensing fees for UMTS/HSPA.
* China Mobile shut down their TD-SCDMA network a few years ago, [https://www.commsupdate.com/articles/2019/03/11/china-mobile-closing-down-3g-system-complete-switch-off-expected-by-2020/ around the end of 2019].
* 5G band n258 is 24GHz, not 26GHz. [https://www.t-mobile.com/support/coverage/t-mobile-network Source from T-Mobile here.]
* "CBN" is not a wireless carrier in China. They own the 700MHz spectrum, which they're allowing China Mobile to use for 5G service. [https://www.mobileworldlive.com/asia/asia-news/cbn-china-mobile-settle-700mhz-5g-plan The network is operated by China Mobile.]
A few questions I had:
* Why is Cellular (CLR) referred to as 850MHz when it's used for LTE/5G, and 800MHz when it's used for CDMA? It's exactly the same frequencies. Seems inconsistent and will confuse people.
* Why is 2.5GHz referred to as 2.5GHz when used in the US and China, but "2.6GHz IMT-E" when used by other countries? The frequencies are the same. The Canadian government [https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/h_sf10939.html refers to the spectrum] as 2.5GHz BRS. There's no difference in frequency between band 7 and band 41. The only difference is that one is FDD and one is TDD.
* Bell/Telus in Canada share a single RAN and all of their spectrum. It's fairly redundant to list them separately, since they operate as one shared network with exactly the same coverage and spectrum.
