Gone are the days when mobile phones were used mainly for voice
calls. Now mobile phones have become smart and millions of people are
using Internet through their smartphones. In different countries, the
quality and speed of mobile Internet differs depending upon the progress
of telecom industry.
In your Android smartphone, the strength of mobile Internet
signal is shown using alphabet letters like G, E, 2G, 3G, H and 4G near
the signal bar. These symbols are visible right next to the signal
strength indicator. Have you ever wondered about the meaning of these
symbols / letters? Well, today I will tell you about the meaning of
letters G, E, 2G, 3G, H and 4G in context of the mobile Internet.
Letter G stands for GPRS
(General Packet Radio Service).
It indicates the slowest speed of Internet data transfer in your mobile
phone. When you see G near your signal strength indicator, it is
certain that your net connection is working at the slowest speed.
is considered to be the second generation (2G) mobile technology. It is
the slowest and oldest among all mobile technologies. It is mainly good
enough for sending text messages using apps like WhatsApp. Data rates in GPRS are between 56 and 114 kbit/second.
Meaning of E in Mobile Signal
Letter E stands for EDGE (Enhanced Data Rates for GSM Evolution).
It is also called Enhanced GPRS. This technology lies somewhere in
between 2G and 3G technology. So, some people refer to it as
Meaning of mobile signal symbols and other indicators on your mobile phone screen.
EDGE is faster than GPRS but still not good enough to browse the
Internet. It takes lot of time in loading websites when your signal bar
is showing E letter alongside. Typically EDGE provides a data rate of
400 kbit/second but in ideal conditions data rate of upto 1 Mbit/second
can also be achieved.
This technology also lies somewhere in between 2G and 3G. Those who call GPRS as 2.5G, they refer EDGE as
Meaning of 3G in Mobile Signal
3G means the
of mobile telephone technology. It uses the Universal Mobile Telecommunications System and is based on GSM standards.
3G provides data transfer rates 384 kbit/second. But depending upon how
it is implemented in various networks, the data rate can go upto 42
Usually 3G is faster than EDGE and you can easily browse websites and stream music.
Meaning of H in Mobile Signal
stands for HSPA (High Speed Packet Access). It is an enhanced form of
3G technology. HSPA provides higher data transfer rates than the basic
HSPA can provide peak data rates of up to 14 Mbit/s for downlink and 5.76 Mbit/s for uplink.
When you see letter H near the signal bar in your mobile phone, you can stream music and even YouTube videos without much interruption. But if you want to download a movie, it is going to take a very long time!
Meaning of H+ in Mobile Signal
This is enhanced HSPA.
It is faster than basic HSPA (as explained above). Relatively speedier
data transfer in H+ will make your video to download or stream much more
At present, 4G technology is not very widely available.
So, in most parts of the world, HSPA+ is the fastest speed you can get
through mobile Internet.
Meaning of 4G in Mobile Signal
If you see 4G near the signal bar in your mobile phone,
It means you’re using the fastest mobile Internet connection available on the globe at present.
is the fourth generation of mobile technology. It is also called LTE
(Long Term Evolution). 4G connection works as good as a wi-fi connection
of your home or office. With such a connection you can do everything on
your mobile that you can do on your desktop.
Just to round it all
up, the bars in signal indicator show the strength or quality of the
signal you’re getting at your present location. Also, mobile phone
makers often use a dull color (like gray) to show weak / absent signal
and a bright color (like green and blue) to show good signal.
Tiny arrows in the signal bar show that the data transfer is taking place. The radar like icon shows the wi-fi connection.
