Everything I can find about 5G is either SUPER HIGH LEVEL fluffy hype content or it’s super deep. . So today we’re going to walk the line between the two – geek out a little bit and explore how 5G works but not go agonizingly deep – So, I’ve picked out 5 of my favorite clever engineering tricks that make 5G tick.

Beamforming and beam steering All the technologies before 5G, like 4, 3, 2, and 1G just sprayed signals everywhere. 5G can actually form a beam and send it right to a receiver. It’s called beam forming or beam steering. This works because a 5G antenna isn’t just one antenna, it’s an array of antennas, it’s a bunch of them all piled in together and they are each individually controlled. By adjusting the phase of each antenna element you can actually point the beam in the direction you want it to go. This is known as beam steering, and can be done with simple analog phase shifters for each antenna. Beamforming takes beamsteering a step further and controls both the phase and the amplitude of the signal at each antenna element. With 5G beam forming, the receiver and the transmitter talk to each other to figure out what settings worked the best, where they got the best reception. Beamforming is important for two reasons. The receiver might be moving! It might be a phone you’re walking with or a car driving down the road.

The beam has to follow and maintain the link. It ... https://www.youtube.com/watch?v=zZDUmlsMCPQ
