Cellular wireless systems, e.g., GSM, UMTS, LTE, 5G

Cellular wireless systems, e.g., GSM, UMTS, LTE, 5G -> wireless systems face many of the same information security challenges that wireline systems face.

In addition to that, they face challenges that are unique to wireless, or that are more severe or challenging for wireless than wireline systems. For example, because of mobility, the point of attachment to the network changes from time to time. This makes authentication more challenging. Another example is the broadcast nature of the wireless medium, making communications privacy more of a challenge than in wireline systems.

Use this tag especially where the challenges are of this nature.
