THE GENERATION TALK – 3G AND 4G
Mobile technology generations have been on a rise since its inception. 2G was there for quite some time. With the advent of 3G, both 2G and 3G were used by the mobile users. Later, it took a step ahead and now even 4G is available in the market. 2G and 3G are used the most in the market. 4G is a little new to pick up with the previous Gs, but it is slowly and gradually catching up.
3G and 4G are mobile technologies having certain benchmarks. They have revolutionized the mobile using technologies for the subscribers. Many consumer facilities like conferencing, multimedia, streaming etc. have been transformed. 3G has already caught a grip on the market; 4G is still nascent for the users. As 4G is a new generation, several differences can be marked between the two.
3G – THIRD GENERATION NETWORK
3G technology is faster than 2G and hence is gradually replacing 2G. The main advantage of 3G over 2G is that it not only provides the internet services but also provides faster access with voice. However, 3G is the best connecting network at present as far as mobile communication is concerned, especially mobile internet. 3G networks allow simultaneous voice and data services with speed variation from 200 kbit/s and if its only data it may deliver several Mbit/s. (Mobile Broadband).
Technically, 3G uses a combination of circuit design and packet design. Circuit design is the oldest and hence has the capacity to hold the connection for a longer time. Packet design is the wireless technology and is the core part of the internet data transmission. Amalgamation of both helps it to perform faster.
4G- FOURTH GENERATION NETWORK
4G is catching eyes globally due to its high speed rate. It offers the speed at 100 Mbit/s for moving users and 1GB for stationery users, which is a revolution in wireless access technology. It is almost like getting a LAN card or an Ethernet connection on your mobile. If your mobile has atleast 54 Mbit/s downloading facility than with the help of 4G, you can run any internet application as you do on your desktop. You can even make VoIP calls from your handset. However, it also provides a facility wherein you do not need to change your number or opt for a new number if you move to a new place. But, if it is within the area of your Wi-Fi connection than the calls can be diverted on your phone. You can make video calls or conference calls even while you are travelling. 4G Technology uses packet switching network.
WHO WINS THE GAME?
Globally 3G is used widely as far as mobile technology is concerned while 4G is considered to be an extension of 3G. There are a lot many differences that set apart the two technologies. 3G use both circuit and packet based network which means that it uses both wired and wireless technology; while 4G uses only the packet technology which makes it first generation of technology to be completely wireless.
4G is much faster and is like a mini computer. As per 4G specifications the speed should be 384 kbps in stationary mode and 100 mbps in mobile environment. The speed is much lower in 3G being 2Mbps in stationary mode whilst 4G specifications it should be 1 Gbps.
4G network is all IP whereas 3G a mix of circuit and packet switching network. Notable point is that many companies that fall under 3G started dubbing their companies as 4G. In fact they are not compliant for 4G and are termed as 3.9G. 3.9 G depends on spatial multiplexing, which is basically an antenna system, used by International Telecommunication Union (ITU), deployed for transmitting and receiving of data. Earlier in 3G there was smart antenna used, but 4G uses number of these antennas for speeding and facilitation of the data transfer process.
