From what I understood you physically lose the EPS network registration
and fall back to 3G / 2G. How is this the same as the suspended
property where your attached status does not change?

The current GPRS logic is controlled with the equivalent of CGATT. This
is a well-defined command by 3GPP, but it is not applicable to EPS
domain. It is applicable only to PS domain, correct? If so, then the
powered property does not map to LTE at all. Your proprietary CFUN/COPS
map to the TechnologyPreference setting in RadioSettings.
