This industry changes rapidly. Today, 4G networks are being upgraded to the 5G standard which makes them faster.
The newer network generations enable more innovative devices and applications. Older cell phone technology is gradually getting progressively eliminated in favour of the newer generation.
1G
Since the first cellular phone networks began in the 80s, each new generation of mobile technology has ushered in higher speeds and improved quality. Each new generation also has distinct advantages and features that are improved on the previous one.
The first cellular phone networks (also known as 1G) used analog technology, allowing users to make voice calls, but only. The 2G generation that followed, introduced digital voice and text messaging services.
The 2G technology was later followed by 2.5G networks that added packet-switching with GPRS as well as EDGE. It was these networks that opened the way to applications that require speedy data. The speed at which a data connection on phones is limited. This limitation is often imposed by data plan use limitations, hotspot caps, and throttles for video.
2G
2G enabled wireless data transfer for SMS, on top voice. Using similar control mechanisms that were used for talking, data transfer allowed pictures and text messages to be sent from one cellphone to another. It was so widely used that it revolutionized communication for the ages. Also, candy bar-style phones like Nokia 3210 sold over 160,000,000 units.
Globally 3G lap dat mang wifi viettel networks came out as well as mobile internet was introduced. Users could browse on the internet or utilize basic applications. It also paved the way to more advanced capabilities like HD Mobile TV and videoconferencing.
The networks enabled speedier data transfer, which enabled advanced capabilities like HD mobile TV and video conference. This also allowed to develop mobile IoT applications such as NB IoT and LTE M.
3G
The growing usage of smartphones has made evident that 2G networks were not sufficient anymore to handle the data flow. The need for new technology to satisfy the ever-growing demands of the customer arose.
GSM technology is the initial stage in the conversion of cellular networks from analogue to digital. First 3G networks was born out of this.
3G provides significantly faster speed of data transfer than previous models. The network also enabled the internet to be connected via mobile devices, which allowed businesses to stay connected while on the go.
It is the end of 3G, as many operators have switched to 4G. Alarms for your home, GPS and mobile phones will be affected. There are steps you can follow to prepare for the change and ensure that your equipment is functioning smoothly.
4G
It is expected that the 4G evolution of mobile networks will change everything. The new mobile generation provides higher data speeds, greater connection density and lower latency.
With 3G networks already oversaturated with customers and speed of data, 4G offers the ability to provide advanced mobile gaming services, HD mobile TV, video conferencing, and IP phone calls. In order to achieve this, it uses beamforming using directional antennes in order to increase Ricean factor gain and increase SNR.
The smartphone has been a massive driver of the ecosystem of 4G. This device helped make 4G an international successful. But it also is expected to allow intelligent innovations to be made across a range of sectors. The new technologies will allow companies to improve efficiency while reducing cost. These innovations will also raise the standard of living across the world.
5G
When newer and stronger technology becomes available, they will impact our everyday life in unexpected ways. It is expected that 5G technology can handle huge amounts of data with very low latency, which means the buffering of VR and streaming applications will be made obsolete.
One way that 5G achieves such fast speeds is by using millimeter wave (mmWave) frequencies that can carry more data than radio waves of other types. It also uses beamforming to target devices for stronger signals, consuming less power than previous generations of mobile networks.
The evolution of mobile technologies is driven by the same factors like previous generations, including additional services, higher speeds and increased throughput. However, this time this change could be more drastic.
