Enhanced Mobile Broadband (eMBB): Provide higher data rates, ensuring faster downloads and uploads.
Ultra-Reliable Low Latency Communications (URLLC): Enable applications like autonomous vehicles, remote surgery, and industrial automation by ensuring low latency and high reliability.
Massive Machine Type Communications (mMTC): Connect billions of devices to support the Internet of Things (IoT) ecosystem.
b. Technical Features:
Higher Frequencies: 5G utilizes higher frequency bands like mmWave (millimeter wave) frequencies, which allow for greater bandwidth and faster data rates. These higher frequencies come with challenges like shorter range and poorer penetration through obstacles.
Massive MIMO (Multiple Input, Multiple Output): This involves using a large number of antennas at both the transmitter and receiver to increase throughput and spectral efficiency.
Network Slicing: This allows the creation of multiple virtual networks on a single physical infrastructure. Each slice can be optimized for specific applications or services.
Edge Computing: By moving computation closer to the data source (at the edge of the network), 5G reduces latency and enables faster processing of data.
Network Function Virtualization (NFV) and Software Defined Networking (SDN): These technologies make the network more flexible, scalable, and efficient by decoupling network functions from proprietary hardware and centralizing network control.
