There is no doubt that technology for cellular phones is rapidly evolving. As of today, 4G networks have been upgraded to 5G. They will now become even more efficient.
As each generation of networks comes out, new and better devices are accessible. Older cellular technology will gradually become obsolete as cellular technologies continue to evolve.
1G
Since the very first cell phone networks launched in the 1980s every next generation of mobile phone network technology has brought faster speeds and better quality. Every new generation has unique benefits and features that are an improvement over previous generations.
1G, also known as analog phone technology, was the first to use only voice calls. The next generation of 2G brought digital voice messages and voice calls.
2G was then followed by 2.5G networks that included packet switching using GPRS and EDGE technology. The 2.5G networks opened the way to high-speed mobile data applications. There are some limitations on the speed of a mobile network. These limitations are often due to restrictions on data plans, caps for hotspots and video slowdowns.
2G
2G enabled wireless data transfer to SMS and voice. Using the same control channels as speaking, data transfer made it possible pictures and text messages to be transferred from one cellphone to another. The feature became so popular, it revolutionized how we talk. Additionally, candy bar phones like Nokia 3210 sold over 160,000,000 units.
The global introduction of 3G networks brought mobile Internet access. This enabled users to browse the internet and use simple apps. This also opened the door to more advanced capabilities like HD Videoconferencing and Mobile TV.
In addition to speedier data transmission, 4G networks enabled more advanced functionalities like HD TV on mobile devices and video conferencing. This innovation opened the door to IoT-based mobile apps, such as NB IoT or LTE.
3G
Due to the growing popularity of smartphones, it became clear that 2G would not be enough for data traffic. As a result, the need for new technology was to meet the increasing demands of consumers.
GSM networks developed from analog to digital technology in the 1990s. In the 1990s GSM networks came into use as the first step toward 3G.
The 3G network offered significantly higher data transfer rates than its predecessors. It also allowed for the internet to be connected via mobile devices, which allowed businesses to stay connected while on the go.
Many carriers are preparing to close down their old networks, and then take them over by 4G LTE. This will impact the technology of alarm systems for homes as well as GPS devices. There are steps you can do today to prepare for the switch and maintain your hardware.
4G
Evolution of 4G networks will transform the world of mobile technology. This new generation of mobile phones provides higher data speeds as well as a higher density of connections and lower latency.
In a time in which 3G networks are overloaded with users and speeds for data are slow, 4G offers a level of quality which allows games on the move, lap cap quang viettel HD Mobile TV, video conference and IP Telephony. To achieve this, it uses beamforming using the use of directional antennes to increase Ricean factor gain and increase SNR.
The smartphone was a huge driver of the ecosystem for 4G. It is thought to be the reason why 4G such a success. But, it’s expected to act as a catalyst for smart innovation across a variety of sectors. The technology can improve business efficiency and reduce cost. These innovations will enhance the standard of living for people around the world.
5G
The advent of new and more powerful technology will affect our lives in surprising ways. As an example, 5G is expected to be able to handle huge amounts of data with extremely low latency — meaning that buffering screens on streaming services and virtual reality applications could become a thing of the past.
It is possible to get 5G speeds so fast through millimeterwaves (mmWave). These frequencies can send more data per radio wave than any other. Beamforming is used to pinpoint devices with the strongest signals.
Mobile technology will evolve in the same way as it did with previous mobile network generations. More services as well as faster throughput will drive the evolution. But this time, the changes may seem more radical than ever previously.
