NIST Special Publication 800-187Guide to LTE Security
Cellular technology has caused large changes throughout society in recent decades. Besides providing telephony services, cellular devices store and process personal information, provide enterprise connectivity, and act as the primary portal to the internet for many individuals. Phones, tablets, laptops, wearables, cellular modems in vehicles, and other industry specific equipment all have the ability to access cellular networks. The cellular infrastructure of the United States is transitioning from older 2nd Generation (2G) and 3rd Generation (3G) cellular technologies to newer 4th Generation (4G) technologies such as Long Term Evolution (LTE). LTE is now the dominant air interface technology across the United States and is seeing rapid adoption in countries across the globe.
