Frequency Spectrum: 5G operates across three spectrum bands:
Low-band (sub-1GHz)
Mid-band (1GHz - 6GHz)
High-band (mmWave, 24GHz and higher).
Key Features:
Enhanced Mobile Broadband (eMBB): Provides faster speeds and more capacity.
Ultra-Reliable Low Latency Communications (URLLC): Enables applications like autonomous vehicles and remote surgery.
Massive Machine Type Communications (mMTC): Connects a large number of devices with minimal power consumption.
Network Slicing: 5G introduces the concept of network slicing, allowing operators to create multiple virtual networks with different characteristics on a single physical infrastructure. This is crucial for catering to diverse use cases.
MIMO and Beamforming: 5G utilizes advanced multiple-input, multiple-output (MIMO) antennas and beamforming technologies to improve spectral efficiency and increase capacity.
Core Network Evolution: 5G uses a new core network architecture known as the 5G Core (5GC), designed to be more flexible, scalable, and capable of supporting diverse services.
Security: 5G incorporates enhanced security mechanisms, including improved encryption algorithms, mutual authentication, and secure network slicing.
