You will surely see the various symbols H, 4G, 3G, G, E and H + on your smartphone. Do you know the difference between these signs? In this article, we describe the exact meanings of these signs and the reasons for their presentation.
Each of these symbols indicates what type of data network your smartphone is connected to. Different networks, according to their signage, offer different features and speeds of the Internet.
General Packet Radio Service: G-GPRS)
GPRS is an abbreviation for General Packet Radio Service, which can be seen with the G icon on the smartphone. This service is called the second-generation Internet (2G), which provides the ability to transfer data in bulk. The next generation of mobile telephony and SMS services like the Internet and MMS.
Enhanced Data GSM Evolution: E-EDGE)
EDGE stands for Enhanced Data Rates for GSM Evolution, which is like GPRS in the second generation of mobile networks. However, the speed of receiving information is more and at around 48 kilobytes per second. The 2.5G Gigabit Ethernet is also known as the E-Gage for mobile phones.
3G is a third-generation mobile phone that, along with the capabilities of the previous generation, also provides video connectivity. 3G stands for UMTS. The speed of communication in the third generation is much better than the previous generations, and it is visible on mobile phones with the symbol 3G.
High-Speed Down-Link Packet Access: H-HSDPA)
This generation works on 3G mobile networks and is just the speed of getting more information. In this case, the speed is up to 14 MB, which is equivalent to 1.75 MB / s. With this generation, it's easy to see videos on the Internet with HD resolution. This is the 3.5G generation. On HSDPA handsets, the symbol is H.
Evolved High-Speed Packet Access): H + - HSDPA Plus)
The HSDPA + is the fastest version of HSDPA, with data downloads at about 21 MB per second in this generation. This generation is also called the fourth generation mobile phone. The HSDPA Plus generation is featured on mobile phones with the H + symbol.
The 4G is the fourth generation of mobile networks, which is currently the fastest and most recent generation of networks. The data transmission speed in this generation is about 37 megabytes per second. In this generation, with high speed, you can easily watch HD movies. The maximum speed defined for the 4.5th generation is also 1.2 GB / s.
And in the not too distant future 5 G
What is the fifth generation Internet or 5G?
Currently, the LTE network and, in some parts of the world, the LTE-A network is commonplace. The next generation of goals, which has a very simple name, is developed by the Mobile Network Union and includes the following:
• Speeds up to a few tbsps (for tens of thousands of users)
• 1 Gigabit Internet for 10 employees working in a business office.
• Hundreds of hundreds of connections or communication paths to connect massive network of sensors to the Internet (on the Internet, objects and smart devices)
• The network efficiency should be much better than 4G; in other words, the available bandwidth can be used more thoroughly.
• Coverage is optimized.
• Increases signaling efficiency.
• Latency of the network is far less than the 4G network.
Among the above, it's very important to have at least 1 gigabits per second, which is several times faster than LTE, delay of less than 1 milliseconds, and more energy efficient. In fact, the 5G network is not only introduced for a higher speed experience, but it is supposed to introduce the smart home appliances, work environment and city into a large and wider network.
