Difference between 4G vs 5G

5G is widely believed to be smarter, faster and more efficient than 4G. It promises mobile data speeds that far outstrip the fastest home broadband network currently available to consumers. 

With speeds of up to 100 gigabits per second, 5G is set to be as much as 100 times faster than 4G. 5G is a new digital system for transforming bytes - data units - over air. This new interface, which uses millimeter wave spectrum, enables more devices to be used within the same geographic area, such as that used by virgin mobile; 4G can support about 4,000 devices per square kilometer whereas 5G will support around one million. 

Speed

Speed is one of the most highly anticipated elements of the next generation network.5G is expected to be nearly 100 times faster than 4G. With speeds like that, you could download a two-hour film in fewer than 10 seconds, a task that takes about seven minutes on 4G (no more panicking while trying to download your in-flight entertainment on the tarmac before the plane takes off). 

Capacity

Too many devices trying to use the network in one place can cause congestion. The network infrastructure just can't cope with mass numbers of devices, leading to slower data speeds and longer lag time for downloads. 5G is expected to solve that issue and then some. The next generation network is expected to have significantly more capacity than 4G. That will mean not only a better connection for everyone's phones, so you can more easily brag on social media about being at the big game because of a great signal booster. 

It will make it possible to connect many, many more devices to the network. Latency: A small but significant difference exists between speed and latency, which is the time it takes for devices to communicate with each other or with the server that's sending them information.

Speed is the amount of time it takes for your phone to download the contents of a webpage. Latency is the time between when you send a text to a friend's phone and when their phone registers that it has received a new message. 

Although latency is measured in milliseconds, all those milliseconds add up when sending and receiving huge packets of information for something as complex as video or self-driving car data.Latency is already low with 4G, but 5G will make it virtually zero.

Evolution of 4G and 5G

G refers to the Generation of wireless phone technology. Mobile technology has advanced rapidly in recent years. From the first generation to the fifth many changes have been made, some of the basic features which have been added, improved, and changed over the years. 

The wireless phone technology has now become a necessity and no business can operate without it. It has become more advance and efficient. From contracts and deals of millions and billions to routine office tasks all require wireless phone technology. Some of the technical changes in “Generations” can help understand better how 4G and 5G have evolved.
