I've been hearing about "5G" for a while and honestly didn't have much of an idea of what it meant, so BBC news put together a 45 second video that gives a good, general explanation. In today's blog, you'll see the video and learn a little more about 5G. First, here's the BBC News video:
Superfast 5G, or fifth generation, mobile networks are already on offer. But how is it different to what's come before? BBC Panorama explains.
HOW DOES 5G WORK? - 5G is the fifth generation wireless technology for digital cellular networks that began wide deployment in 2019. Like other cellular networks, 5G networks use a system of cell sites that divide their territory into sectors and send encoded data through radio waves. Each cell site must be connected to a network backbone, whether through a wired or wireless backhaul connection.
SO 5G HAS A SHORTER REACH FROM AN ANTENNA? - Yes. 5G will use new higher radio frequencies to transmit data, which are less cluttered and carry information much faster. While these higher bands are faster, they don't carry information as far. This means that smaller multiple input and output antennas will be implemented - boosting both signals and capacity.
HOW FAST IS IT? - 5G millimeter wave is the fastest, with actual speeds often being 1–2 Gb/s down. Frequencies are above 24 GHz reaching up to 72 GHz which is above the extremely high frequency band's lower boundary.
