When you use the internet of your smartphone you should have noticed the presence of the “E”, “G”, “H”, “H +”, “3G” or “4G” signs on the side of the device’s signal bar, right?

If you were curious to see the letters, but did not have time to search, know that the answer is simple: the signals symbolize the type of technology being used at that time, as well as the oscillation of the connection speed.
The difference between “E”, “G”, “H”, “H +”, “3G” and “4G”
- The letter G represents the General Packet Radio Service (GPRS) technology that began to be used in 2000. It can generate data with speeds up to 171.2 Kb/s (kilobits per second);
- The letter E symbolizes EDGE (Enhanced Data Rates for GSM Evolution) technology.Such technology is slightly faster than the previous one, represented by the letter G. It can reach the maximum speed of 473.6 Kb/s;
- The letter H refers to HSPA (High Speed Packet Access) technology or the HSDPA (High Speed Downlink Packet Access) standard.This connection reaches a speed considered high, of up to 14 Mb/s (megabits per second);
- The H + symbol indicates the technology called Evolved HSPA (Evolved HSPA).This can reach speeds up to 168 Mb/s for download and 22 Mb/s for upload;
- THE3G stands for third-generation mobile technologies.Standards like HSPA and HSPA + are often called 3G, however, they are not.When the 3G symbol appears on a device, it generally refers to UMTS (Universal Mobile Telecommunications Service) technology, which can reach speeds of up to 2 Mb/s.
- Calling the fourth generation of the mobile internet, 4G is the successor to 3G.Among the differences, the main one is precisely the speed of connection and the loading of data.The 4G connection may be approximately 10 times faster than 3G, or 3G.
Long Term Evolution , or simply LTE, the fourth generation mobile data transmission technology that was developed based on GSM and WCDMA. As a feature, technology prioritizes data traffic rather than voice traffic, as it did in previous generations.
Now you know why your device shows these letters through the internet connection.
