5G is the fifth generation of wireless data networks. The new network aims to deliver data rates that are 10 to 100 times faster than current 4G networks.
Users should expect to see download speeds on the order of gigabits per second (Gb/s) which makes it the biggest leap in speed for wireless devices.
5G will eliminate as well latency, or lag, that we already experience between sending and receiving information.
The upgrade to the 5G is not like the upgrade that we had before from the 3G to the 4G since it is a completely new technology.
How it works?
5G networks are digital cellular networks, in which the service area covered by providers is divided into small geographical areas called cells.
The network function on a whole different waves which are Millimeter waves.
3G operated on a radio wave frequency of 1.6 - 1.9 Ghz, 4G operated on a frequency of around 2.5 Ghz meanwhile 5G operates on a frequency of 30 - 300 Ghz which are 10 - 100 times higher that todays used network.
The limitation, is that 5G can not penetrate walls and obstacles, which will demand building many signal towers that will cover small areas of around 100 meter each.
Is 5G dangerous?
Although 5G may improve our day to day lives, some consumers have voiced concern about potential health hazards. Many of these concerns are over 5G's use of the higher energy millimeter-wave radiation.
Pro-5G claims that Millimeter waves are non-ionizing waves because they have longer wavelengths and not enough energy to damage cells directly which make them harmless to us humans.
Let us face it, plenty of previous studies have proven that exposure to 2G, 3G and 4G radiations resulted into an increase in brain and adrenal gland tumors, so exposure to very high non-ionizing radiation may still be responsible for a range of illnesses, from brain tumors to chronic headaches.
5G will definitely have a transformational impact on our lives and enable fundamentally new things, but what those types of applications will be and what that impact is, we can't say for sure right now.
