This document contains information about 4G technology, including definitions of common abbreviations used in 4G such as SIM, UE, EPC, and LTE. It also provides a high-level overview of how 4G connections work using technologies like MIMO and OFDM to transmit over radio frequencies. The architecture of 4G is depicted in a diagram. Key differences between 3G and 4G networks and technologies related to 4G such as LTE, LTE+, and VoLTE are also mentioned but not described in detail.

4. PRINCIPLE OF 4G
TECHNOLOGY
A 4G Connection works via an antenna that transmits over radio
frequencies, enabling mobile devices to connect to mobile networks. The
transmission and receiving capabilities of 4G are powered by MIMO
(Multiple Input Multiple Output) and Orthogonal Frequency Division
Multiplexing (OFDM) technologies. Both MIMO and OFDM enable more
capacity and bandwidth in comparison to 3G
