What is 5G? An Eletrical Engineer Explains the Technology

5G means fifth-generation cellular network technology, and the technology allows wireless communication. For example, from your cellphone to a cell tower, which conducts it to the internet. 5G is a network service offered by telecommunications providers and is not the exact same thing as the 5 GHz band on your Wi-Fi router.

5G presents an order of magnitude– 10 times– more bandwidth than its predecessor, 4G. The higher bandwidth is conceivable since over and above low and medium frequency radio waves. 5G employs more higher-frequency waves to encode and carry information.

Bandwidth is comparable to the width of a highway. The wider the highway, the more lanes it can have and the even more vehicles it can hold all at once. This makes 5G faster and able to manage many more devices.

5G Technology and Smartphones

A lot of newer smartphones work with 5G networks.

5G can provide speeds of around 50 megabits per second, up to more than 1 gigabit per second. A gigabit per second connection lets you download a high-definition movie in short of a minute. Does this imply n no more bad cell connections in crowded places? The enhanced bandwidth will assist, however equally as enhancing the number of lanes on highways does not always lower traffic jams, as even more people use the increased highways, 5G is most likely to carry a whole lot even more traffic than 4G networks, so you still could not obtain a great connection in some cases.

Along with linking your phone and cellular-enabled laptop, 5G will be linking numerous other devices varying from picture frames to toasters as part of the Internet of Things revolution. So although 5G can take care of as much as a million devices per square kilometer, all that bandwidth could be quickly consumed as well as call for even more– a future 5.5 G with much more bandwidth.

Flavors of 5G

5G can utilize low-, mid-, and high-band frequencies, each with downsides and benefits. Lower-frequency waves can go farther yet are slower. Using higher frequency waves signifies information can travel much faster, yet these waves can only go limited distances. Higher-frequency 5G can reach gigabit-per-second speeds, which promises to render ethernet and other wired connections obsolete in the future. Currently, however, the higher frequency comes at a greater cost. Hence, deployed just where it is most required: in packed urban environments, stadiums, convention facilities, airports, and concert halls.

A kind of 5G service, Ultra-Reliable and Low-Latency Communications can be utilized where data requires to be sent without loss or interruption in service– as an example, controlling drones in disaster areas. Eventually, after the technology is much more durable, it might even be utilized for remote surgery.
