How do 5G base stations work?

5G will use ‘massive’ MIMO (multiple input, multiple output) antennas that have very large numbers of antenna elements or connections to send and receive more data simultaneously . The benefit to users is that more people can simultaneously connect to the network and maintain high throughput.

What type of connection is 5G?

A: 5G is based on OFDM (Orthogonal frequency-division multiplexing), a method of modulating a digital signal across several different channels to reduce interference . 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.

What spectrum does 5G use?

Today, a majority of commercial 5G networks rely on spectrum in the 3.5 GHz range (3.3 GHz-4.2 GHz) . This momentum makes it vital that regulators assign as much contiguous 5G spectrum as possible in the range. However, 5G needs more mid-band spectrum to maintain quality of service and meet growing demand.
