Fahamu maana ya hizi ALAMA ambazo ukiwa unatumia simu yako kwenye internet huwa zinajitokeza au kubadilikabadilika!
About the abbreviations:
G stands for GPRS and is the slowest standard, used is the GSM network (2G).
E is an extension of GPRS, it is called EDGE and it is correspondingly a little faster, but still uses the old GSM network (2G).
3G stands for UMTS and is the successor to the GSM network and faster.
H and H+ are standing for HSPA and HSPA+. Both use the UMTS network, where H is faster than 3G and H+ is faster than H.
4G stands for LTE and is the fastest.
Development of standards and networks
At the beginning of the digital mobile phone age, there was only the GSM network as a replacement for analog systems. According to this, GSM is also called 2G, the second generation. Gradually, new, better and fast systems developed. GPRS and EDGE also use the GSM network, the higher speeds of EDGE is the result of an improved technology. The third generation is the UMTS network (3G). Again, on the 3G network, the improvements HSPA (H) and HSPA+ (H+) are based, allowing faster transfer rates in the 3G network. Finally, the fourth generation named LTE (4G) was presented, which again brings a significant increase in transfer rates.
