Frequency Spectrum: 5G operates across a spectrum of frequencies, including low-band (sub-1GHz), mid-band (1-6GHz), and high-band (mmWave, 24-100GHz). The utilization of these frequency bands allows for a balance between coverage and speed.
Enhanced Mobile Broadband (eMBB): 5G promises significantly higher data rates compared to its predecessor, 4G LTE. eMBB is a primary use case, aiming to deliver peak data rates of up to 20 Gbps.
Ultra-Reliable Low Latency Communications (URLLC): For applications like autonomous vehicles and remote surgery, 5G aims to provide ultra-low latency (as low as 1ms) and high reliability.
Massive Machine Type Communications (mMTC): This aspect of 5G targets the connection of a massive number of devices, making it suitable for the Internet of Things (IoT) applications.
Beamforming & MIMO: 5G employs advanced antenna technologies such as Massive Multiple Input Multiple Output (MIMO) and beamforming. These techniques help in improving spectral efficiency and increasing network capacity.
Network Slicing: This is a feature where multiple virtual networks can be created on top of a single physical network infrastructure. It allows for the customization of network resources for specific use cases, ensuring optimal performance and reliability.
