Discuss trends in cellular data transmission speeds

There are various types of cellular data with the different transmission speeds that are: 1G, 2G, 3G and 4G.

1st generation network:

The 1st generation network is known as cellular network data transmission that contain analog system. It has 2.4kbps speed range. It is widely used in various services like public voice.

2nd generation network:

The second generation network is basically based on the digital system. The global positioning system (GSM) is one of the important service in the 2nd generation network. It basically provide different types of services that are:

GSM provide upto 2.5G range of speed and GSM EDGE upto 23kbps services.

3rd generation network:

It the wireless service that is basically based on the digital system. It provide various types of services like mobile interne, video calling and wireless type of telephones.

4th generation network:

It is one of the high digital data transmission rate and it is basically represented as the LTE. The 4G provide many types of services like multimedia services and telephone and gaming services.

Worldwide, operators and manufacturers like Samsung, Xiaomi, LG, Motorola, ZTE or Huawei are adapting equipment to offer consumers this kind of revolutionary connectivity that comes to the market.

The expectation that we are facing a technological breakthrough is because 5G has the potential to change the way we use the internet.

If 4G and its variations allowed us to connect people, 5G will allow us a much broader connection to the things around us. Your phone, for example, will probably be faster than your home's wifi.

The speed of 4G, which is probably within your grasp right now, is 1 Gbps per second. The new network, at its full potential, will be able to deliver a standard speed of 20 Gbps per second, according to UK regulator Ofcom.

What does this mean in practice? How long does it take to download a 5G video? And watch a movie in streaming?

Downloading a 1-hour playlist on Spotfy took about 7 minutes with 3G, 20 seconds with 4G, and with 5G that time would be 0.6 seconds.

If you want to take a movie to watch while you're on the go - offline - service offered by platforms like Amazon Premium or Netflix - it will take you 3.7 seconds to download it while spending about 2 minutes on 4G.

The popular Fortnite game takes 14 minutes to download using 4G technology and the expectation is that with 5G it will take 24 seconds.

In terms of speed, one of the key factors is called latency, ie the network's responsiveness to a request.

With 5G, it will be reduced to one millisecond - a significant gain compared to the 20 seconds of the 4G network.

It's an essential factor "for activities such as broadcasting a live game in virtual reality or for a surgeon in New York to control a pair of robotic arms performing a procedure in Santiago," explains the next-generation networking optics expert, Abraham Valdebenito in an article.

In short, we can send and receive data almost instantly.
