Why is there a delay in the implementation of 5G?

5G is the newest wireless networking technology for phones, smartwatches, cars, and who knows what else, but it’s not yet available in every region around the world. Some estimates forecast that by 2025, we’ll reach 3.6 billion 5G connections, a number expected to grow to 4.4 billion by 2027 .

5G has different challenges which are not practically achieved as expected theoretically. Some challenges like coverage area, spectral efficiency, latency, interference, energy efficiency, and power consumption are explained as follows.

AT&T, which along with Verizon last year bought a swath of spectrum for more than $80 billion, said in a statement early Tuesday that it will “temporarily defer” turning on some of the towers it had planned to use to deploy 5G in order to ensure they don’t interfere with aircraft radar altimeters , which help planes …
