ESN is equivalent to IMEI in GSM/UMTS networks. IMEI is tied to equipment, and never changes, just like ESN. CDMA networks use IMSI to identify subscribers (as opposed to the equipment serial number) just like GSM/UMTS. IMSIs are provisione

> There's no technical reason why CDMA networks couldn't have supported SIM cards in their phones, but it was just never done. Indeed. RUIMs (and CSIMs) were standardized for CDMA, but carriers in the americas never bothered with them.

That's a bit of a simplification. Because VoLTE is still being standardized, phones must keep multiple modems active and multiple receive portions of the transceiver ASIC powered on in order to be able to receive voice calls when on LTE. Th

Do you have particular insight into disease caused by non-ionizing radiation that the rest of the world is missing? I've seen no study that has been able to conclusively link non-ionizing radiation to human health problems, or really any ot

It also completely ignores earlier distributed source control projects like GNU Arch. 2005 was when there was an open source distributed VCS that was fast and pleasant to use, but implementations of the idea are older than that.

At least as far as CDMA and WCDMA go, control signalling is shared for all mobiles camped on a cell. In CDMA, while a mobile is just camping there's not a lot of traffic going between the cell and the mobile on the access and reverse access

> The one issue with T-Mobile is it uses the fairly nonstandard 1870 MHz frequency. I don't know of any other carrier that does (anywhere). I think you mean GSM/UMTS band II (PCS), as 1870 is in the uplink portion of PCS (1850–1910MHz).
