The original ITU rights for ICO (later purchased by Omnispace) were S-band though. Apparently 3GPP Nb-IoT is expected to use LTE (typically in frequencies already in use by a carrier or using some bandwidth in the guard bands), or allowed to exist in dedicated spectrum, so I guess they are thinking of doing Nb-IoT in S-band then? That's dedicated equipment though unless you are using SDR gear...https://omnispace.com/The marketing fluff is heavy of the 5G buzzwords and not much else.
