LTE does perform authentication of the tower, it's one of the reasons cell site simulators are becoming less useful---phones that refuse a downgrade to 3G will refuse to fully associate with a simulated site, so only limited information about the phone (some identifiers) can be obtained.
- stacktrust 3y ago2017, https://arxiv.org/abs/1702.04434 https://arxiv.org/abs/1702.04434 > IMSI Catcher attacks are really practical for the state-of-the-art 4G/LTE mobile systems too. Our IMSI Catcher device acquires subscription identities (IMSIs) within an area or location within a few seconds of operation and then denies access of subscribers to the commercial network. Moreover, we demonstrate that these attack devices can be easily built and operated using readily available tools and equipment, and without any programming. We describe our experiments and procedures that are based on commercially available hardware and unmodified open source software.
