What does it mean by G, E, H, 3G network symbol on Mobile Signal bar?

Generally when use internet on our smartphones we have seen some symbols near our network indicator i.e. H, E, G, 3G and 2Gd.

Meaning of the symbol 3G and H while using internet


A very first step you have to know about '3G'. Which indicates towards the third generation and when you surf the internet then it gives you the speed of 250 kbps to 350 kbps?


'H' stands for HSPDA (High Speed Downlink Packet Access) higher version of 3G, the speed in this is at least 7.2 mbps or higher. This mode permits you to enjoy the power of internet surfing/downloading or uploading. There is an exception in both 3G and H, a few of persons says that 3G is more powerful than H.


Let's have a look what these symbols say...

• G = 1G (GPRS)

• E = EDGE (2.5G)

• 3G =3G

• H (High Speed Downlink Packet Access) = 3.5G (HSPA+), HSPA 14.4 (really just a 3G standard, marketed as 4G)

• 4G=4G

In order of speed: 4G > H > 3G > E
If the signal indicator says H, it won't also say 4G unless the phone is capable of LTE, which this phone is not.

Another descriptions...

• H or 3.5 G stands for HSPA (High Speed Packet Access) is a new generation communication protocol that allows data connections up to 14.4Mbps download speed and up to 5.8Mbps upload speed per user in good coverage and quality conditions.

• 3G means WCDMA (Wideband Code Division Multiple Access) that is a 3G technology version that allows data connections up to 2 Mbps per user in good coverage and quality conditions.
  
• E stands for Enhanced Data Rates for GSM Evolution, known as EDGE that is 2.5G technology version which can go up to a speed of 264 Kbps.
