Difference between 2G and 3G

"G" is stands for generation. "2G" networks, that means wireless network based on second generation of mobile technology. 2G cellular telecom networks were commercially launched on the GSM standard in Finland in 1991. TDMA (Time division multiple access) and CDMA (Code division multiple access) is used in 2G technology. TDMA allows several users to share the same frequency channel by dividing the signal into different time slots. CDMA service is dispense a special code to user and several transmitters can send information simultaneously over a single communication channel.

2G technology gives the services like all text messages digitally encrypted(information converted into code). 2G and 3G technology have authority to give services like text messages, MMS(Multimedia messaging service), picture messages.

"3G" is the third generation of mobile telecommunication technology. This generation is based on set of standard used for mobile devices and mobile telecommunication services. The networks are executed with the International Mobile Telecommunication-2000(IMT-2000) specification by the International telecommunication Union. 3G technology is the standard for accessibility and speed of mobile devices.

It was first used in Japan in 2001. The 3G technology is known for enabled use of various services like GPS(Global Positioning service) and video conferencing. It also provides better bandwidth and increased speed. This technology is also comfortable with 2G technology because 3G spectrum covers the spectrum of 2G technology. Here, we are discussing about "Difference between 2G and 3G". It will be helpful for you.

Difference between 2G and 3G:

Cost- The network construction and maintenance of 3G is much expensive than 2G. Expenditure of 3G service is excessively high for users.

Data Transmission- Data transmission is the main difference between 2G and 3G. A user find much faster download speed, faster access to the data and applications in 3G networks as compared to 2G networks. 2G networks is less consistent with the functions of smartphone. The data transmission in the 2G network is less than 50,000 bits per sec while in 3G it can be more than 4 million bits per sec.

Function- The 2G technology transmit the information through voice signal while 3G technology transfer data via video conferencing.

Features- The features like video transfer and GPS systems are the additional features of 3G, that are not available in 2G technology.

Frequency- The 2G technology refers the wide range of frequencies in both upper and lower band, under which the transmission depends on factor such as weather condition. 3G is not available in certain region.

Security- 3G offers you best security than 2G technology.

Speed- The downloading and uploading speed available in 2G technologies are up to 236 Kbps while in 3G technology downloading and uploading speed are up to 21 Mbps and 5.7 Mbps respectively.
