Long Term Evolution (LTE) is a standard for wireless broadband communication, primarily used for mobile devices and data terminals. It enhances the speed and capacity of mobile networks, allowing users to access the internet and stream content more efficiently. LTE is part of the 3rd Generation Partnership Project (3GPP) family of mobile communication standards. LTE technology operates on various frequency bands and employs advanced techniques like MIMO (Multiple Input Multiple Output) to improve performance. It supports high data rates, low latency, and better user experiences, making it a crucial step in the evolution of mobile networks, leading to the development of 5G technology.
