There is no doubt that technology for cellular phones has been rapidly developing. Today’s 4G networks are being upgraded to 5G, which makes them more efficient than ever before.
As each generation of networks is released, more and more advanced devices are made accessible. As cellular technologies evolve, older technology will gradually be eliminated and replaced with the next generation.
1G
Since the first cellular phone networks launched in the 1980s, each new generation of mobile network technology has brought higher speeds and improved quality. Newer models also come with distinct features and benefits that make them better than the older ones.
The first network, 1G, was analog and only allowed voice communication. The next generation 2G networks offered the use of digital voice and text messages.
The 2.5G network added the ability to switch packets using GPRS/EDGE. They paved the road for mobile data applications with speedy speeds. But there are limitations to how fast a mobile data connection can be. The restrictions usually come by data plan limits on usage, hotspot caps or throttles for video.
2G
2G capable SMS by adding Wireless data into the existing voice service. Utilizing the same control channels that were used for speaking, data transfer made it possible pictures and text messages to be sent from one cellphone to another. The feature became so popular, it revolutionized how we talk. This also led to candy bar phones like those of Nokia 3210 which sold over 160 million units.
With 3G networks rolling out worldwide, users can now access the internet via mobile devices to access sites and use basic applications. 3G networks allowed for more advanced functions such as HD television mobile as well as video conferencing.
The networks enabled faster data transfers that enabled more advanced features like HD mobile TV and video conference. This technology paved the way for IoT-based mobile applications like NB IoT as well as LTE.
3G
Due to the growing popularity of smartphones, it became clear that 2G was not enough to handle the data flow. It was necessary to develop new technologies to satisfy the ever-growing demands of the customer arose.
GSM technology was the initial step in converting cellular networks from analogue to digital. In the 1990s, GSM networks were introduced as the first step toward 3G.
3G provided a much higher rate of data transfer over prior networks. The 3G network enabled internet access on mobile devices. Businesses could stay connected while on the go.
The final phase of the 3G time period is near and many major carriers will shut down their old networks in favor of 4G LTE. The end of 3G will have an impact on technologies, including cellphones, GPS, home alarms. You can take today to prepare to switch over and keep your hardware.
4G
Revolutionizing the globe is 4G’s wireless network. This new technology in mobile connectivity allows for faster data speeds, higher connectivity density and lower latency.
Due to the oversaturation of 3G networks and their slow speed for data, 4G delivers a high-quality service that allows for advanced mobile gaming and HD mobile TV services. It also enables video conference, IP telephony as well as HD mobile TV. It is accomplished by beamforming using directional antennas to increase Ricean factor, SNR and root mean of delays.
Smartphones are a key driver for 4G. This lap cap quang viettel smartphone is credited with making 4G profitable, and will be expected to drive smart innovation in many different areas. These innovations will aid companies in improving their efficiency while lowering cost. These innovations will also help to improve people’s quality of living around all over the world.
5G
When newer and stronger technology is introduced, they’ll have an unexpected influence on how we live our lives. It is expected that 5G technology can handle huge amounts of data with extremely low latency. This implies that the buffering in streaming services and VR applications will be made obsolete.
It’s possible to achieve 5G speeds so fast by using millimeterwaves (mmWave). These frequencies can send more data each radio wave than other. Beamforming is used to pinpoint those devices that have the highest signal strength.
The mobile technology is expected to change in the same manner as it did with previous mobile network generations. More services as well as more efficient throughput will fuel the development. However, this time this change could be more dramatic.
