The cellular technology industry is constantly evolving. The 4G network is currently being upgraded to 5G, that will speed up faster than before.

The newer network generations enable the most innovative applications and devices. Older cellular technology will gradually be replaced by the latest technology as mobile technologies continue to evolve.

1G

Since the very first cell phones were launched in the 1980s every new generation of mobile technology has ushered in faster speeds and better quality. The newer generations also have their own features and advantages that make them better than those older models.

The first network, 1G, was an analog network that only permitted voice communication. The 2G network was the first to introduce digital voice-over-text as well as digital messaging.

It was followed by 2.5G that combined packet switching and GPRS/EDGE technologies. These networks paved a way for applications that require speedy data. But there are limitations to how fast the mobile data connection could be. This limitation could be enforced by data usage limitations as well as caps on hotspots, and video speed slowdown.

2G

In the 2G time the wireless data transmission integrated into voice communications. It allowed for SMS messages. Data transfer, that utilized the same channel for speaking and text messages, as and pictures for sending between two phones, was possible using data transmission. It was so widely used that it revolutionized communication for the ages. Additionally, candy bar phones like Nokia 3210 sold over 160,000,000 units.

Globally, 3G networks were launched as well as mobile internet was introduced. Users could browse on the internet or utilize basic applications. It also opened the way for the development of advanced features like HD mobile television and video conferences.

4G networks introduced faster data transmission allowing to provide more sophisticated features like mobile web accessibility, HD mobile TV and video conferencing. This technology paved the way to IoT-based mobile apps like NB IoT or LTE.

3G

Increased use of smartphones made it evident that the 2G network was no longer sufficient to manage data traffic. It was necessary to develop new technologies to satisfy the ever-growing requirements of customers was evident.

GSM, or the GSM network, was developed in the 90s. It was the precursor to 3G networks.

3G offered significantly higher speeds for data transfers than its predecessors. The internet was also accessible via mobile phones. This allowed businesses to be connected even when traveling.

The final phase of the 3G time period is near and many major carriers will shut down their legacy networks to make way for 4G LTE. Alarms for your home, GPS and mobile phones will be affected. It is possible to prepare for the change and ensure that your equipment continues to work smoothly.

4G

This 4G network evolution is set to revolutionize the world. The latest generation of mobile connectivity has higher data speeds, as well as higher density connections and less latency.

The 3G networks are already crowded with customers and speed of data, 4G offers the ability to provide advanced mobile gaming services, HD mobile TV, video conferencing, and IP telephony. This is achieved by beamforming using directional antennas to increase Ricean factor SNR, RF and root mean of delays.

The smartphone has been a major factor in the development of 4G. This device helped in making 4G an international successful. But it also will allow for smart innovations to take place across a range of sectors. It will help lower costs and improve the efficiency of dang ky cap quang viettel businesses. The improvements will enhance the lives of people across the globe.

5G

The latest and most powerful technology can have an enormous impact on our daily life. For example, 5G will be able to handle huge quantities of data at extremely low latency — meaning that buffering screens on streaming services and virtual reality apps could very become a thing of the past.

Millimeter-wave frequency (mmWave), a type of radio wave that can transmit more data is one of the ways 5G can achieve such rapid speeds. It also uses beamforming to target the devices to provide stronger signals, consuming less power than previous generations of mobile networks.

Similar to previous generations of mobile networks, additional services and higher throughputs will continue to propel the development of mobile technology. However, this time, it may appear that the changes are more radical.
