How 5G Works
Spectrum used by 5G networks
- 5G utilizes various frequency bands ranging from low to high
- The most commonly used bands for 5G are high frequency (mmWave) bands and mid-band frequencies
1. High frequency bands
- Offer high speed and low latency, but have limited coverage
- mmWave bands have short wavelengths, and therefore operate on a line-of-sight basis
- Typically used in densely populated areas, sports arenas, or event venues
Mid-band frequencies
- Offer better coverage than mmWave, and still provide high bandwidth
- Useful for suburban areas, and more remote regions
The role of small cells, macro cells, and base stations in 5G
- In 5G networks, there are three different types of cells – small cells, macro cells, and base stations
- Small cells are low-powered, short-range access points, useful for crowded indoor areas and outdoor urban settings
- Macro cells provide larger coverage areas, including both urban and rural areas
- Base stations connect individual cells and provide connectivity to the core network.
The difference between 5G NSA and 5G SA architectures
- 5G networks can operate with different architectural setups, namely NSA (Non-Standalone) and SA (Standalone)
- NSA architecture utilizes the existing 4G network infrastructure for certain aspects of communication
- SA architecture is a fully independent 5G network, with its own infrastructure and architecture
How 5G uses MIMO technology to increase speed and bandwidth
- 5G employs MIMO (Multiple Input Multiple Output) technology, where multiple antennas send and receive data simultaneously
- MIMO allows for higher data rates, and improved signal quality
- It also enables beamforming, which means the network can focus its signal on particular users or devices.
