Final answer:
The 4G cellular network architecture standard is called Long Term Evolution (LTE), which is designed to provide high-speed data transmission and supports multiple frequency bands for global deployment.
Step-by-step explanation:
The 4G cellular network architecture standard is called Long Term Evolution (LTE). LTE is a standard for wireless broadband communication. It is designed to increase the capacity and speed of wireless data networks. LTE architecture consists of several key components, including the core network, called the Evolved Packet Core (EPC), and a multitude of radio access networks. The EPC is the backbone of the LTE network, providing high-speed data transmission and facilitating various services such as voice-over LTE (VoLTE) and video streaming.
The radio access network comprises base stations, known as eNodeBs in LTE, which connect users' devices to the core network. LTE features multiple antennas for both transmission and reception (MIMO technology), which significantly increases data rates and network capacity. This architecture supports different frequency bands, allowing for widespread deployment around the world.
