How Does 5G Work?
5G uses a combination of new radio frequencies, small cell networks, and advanced antenna technologies to deliver faster speeds and greater capacity. Here’s how it works:

Higher Frequency Bands: 5G operates on higher frequency bands, known as millimeter waves (24 GHz and above), which can carry more data at faster speeds. However, millimeter waves have shorter ranges, which is why 5G relies on small cell networks to provide coverage.

Small Cell Networks: Small cell towers are smaller, low-powered base stations that are distributed throughout a city or area to ensure that 5G signals can reach users without any interruptions. These small cells are designed to work together to provide seamless coverage and capacity.

Massive MIMO: Massive Multiple Input Multiple Output (MIMO) technology involves using multiple antennas to simultaneously transmit and receive data from many devices at once, improving the capacity and efficiency of 5G networks.

Beamforming: Beamforming directs the signal toward specific devices rather than broadcasting it in all directions. This technology helps to improve the range and quality of the connection by ensuring that signals are delivered precisely where they are needed.
