What is 5G? Explains the electrical engineer

5G stands for the fifth generation in the mobile network technology.

Technologies that allow wireless communication - for example, from your mobile phone to a mobile tower, which you transmit online. 5G is a network service provided by network companies and does not match the 5 GHz band on your Wi-Fi channel.

5G offers maximum order - 10 times - more bandwidth than its predecessor, 4G. Large bandwidth is possible because, in addition to low and medium frequency radio, 5G uses additional high-frequency frequencies to collect and manage information.

Bandwidth is equal to the width of the highway. If the highway is wide, there are many lanes that can carry many vehicles at once. This makes 5G faster and able to handle many other devices.

5G can deliver speeds of up to 50 megabits per second, up to more than one gigabyte per second. A gigabit per second connection allows you to download a high-definition movie in less than a minute. Does this mean that there will be no more bad cell connections in overcrowded areas?

Increasing the bandwidth will help, but just as increasing the number of routes on highways does not always reduce traffic congestion, as more people use extended highways, 5G may carry more traffic than 4G networks, so you may not get it. good communication sometimes.

In addition to connecting your phone to a portable laptop computer, 5G will connect many other devices from photo frames to toasts as part of the Internet of Things version. So even though 5G can handle up to a million devices per square kilometer, all that bandwidth could be used faster and needed more - the future of 5.5G with even more bandwidth.

5G flavors

5G can use low, medium and high waves, each with advantages and disadvantages. Low-frequency waves can travel long distances but are slow. Using high-frequency signals means that information can travel faster but these waves can travel at limited distances.

Higher-frequency 5G can reach gigabit speeds per second, which promises to provide ethernet and other wired connections in the future. At present, however, high frequency comes at a higher cost and thus only used where it is most needed: in congested urban areas, stadiums, convention centers, airports, and concert halls.

5G type of service, Ultra-Reliable, and Low-Latency Communications can be used when data needs to be transferred without loss or disruption to the service - for example, to control drones in disaster areas. One day, after the technology becomes more sophisticated, it may be used for remote surgery.
