Against a pre-authorized list of networks, identified by their PLMN (public land mobile network) IDs stored in the SIM card, and cryptographic keys that the network uses to prove that it really is the network that's authorized in the SIM card. There are two network functions inside the core 4G network responsible for authenticating users, checking what services they're authorized to access, and handling them as they move across towers or roam into/out of range of the network.

I'm here to answer your questions about cellular tech
Hi - I work for Qualcomm. I noticed some recent threads where 4G and 5G technologies were discussed. The comments indicated to me that there's a lot of misconceptions about how cellular technologies work, and the relationship between device capabilities and networks.If you want, I'm available to answer any questions you may have. I promise to stick with the technology and not veer towards...

LTE-U will first seek out channels with no incumbent Wi-Fi (or LTE-U) access points. If no clear channel is found, it'll seek the least occupied one, then evaluate how many other transmitters are using it. It'll then use the channel for a an amount of time proportional to that total number of transmitters. So if sharing with 2 other Wi-Fi access points, it'll take one third of the time. The result is that the impact of LTE-U on Wi-Fi is no more than the impact of Wi-Fi on Wi-Fi.

This is Sherif from Qualcomm. I know LTE-U is a new concept so there's a lot misconceptions around it. I'll be happy to answer your questions.
