The first sentence says "often incorrectly stated as 1700/2100".
Why is that incorrect? In the cellular industry shorthand for band nomenclature (e.g. 850, 900, etc.), this is neither the 1700 band (3GPP LTE FDD band 11) nor the 2100 band (3GPP UMTS Band I, LTE FDD Band 1). Since it is an outlier and has a broader Tx-Rx separation than any other band, it is necessary to indicate BOTH 1700 and 2100. It is more clear to use a "|" (pipe) separator rather than a dash since lists of bands are often separated by dashes. For example, 850/900/1800/1900/2100; adding 1700|2100 differentiates that from 1700/2100 as two separate bands.
Industry standards-wise, this correlates to: 3GPP2 CDMA2000 Band Class 15 3GPP UMTS W-CDMA Band IV 3GPP LTE FDD Band 4
FCC-wise, this originally correlated to what's now designated as AWS-1. The FCC at: https://www.fcc.gov/general/advanced-wireless-services-aws has also defined AWS-2, AWS-3, and AWS-4 bands.
None of those map directly to the 3GPP and 3GPP2 standards bands, at least yet. The new 3GPP LTE FDD bands 65 and 66 do include all or part of the AWS-* bands.
