Question

What is 3G service? what is it use?

Answer 1

3G is the third generation of mobile phone standards and technology, superseding 2G, and preceding 4G. It is based on the International Telecommunication Union (ITU) family of standards under the International Mobile Telecommunications programme, IMT-2000.

3G technologies enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. Additional features also include HSPA data transmission capabilities able to deliver speeds up to 14.4Mbit/s on the downlink and 5.8Mbit/s on the uplink.

Answer 2

3G services means third generation services like 24 hours internet facilities,MMS,GPRS with speed 2 MBPS.After 4 months BSNL is launching this service.

3G :

3G is the third generation of mobile phone standards and technology, superseding 2G, and preceding 4G. It is based on the International Telecommunication Union (ITU) family of standards under the International Mobile Telecommunications programme, IMT-2000.

3G technologies enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. Additional features also include HSPA data transmission capabilities able to deliver speeds up to 14.4Mbit/s on the downlink and 5.8Mbit/s on the uplink.

Unlike IEEE 802.11 (common names Wi-Fi or WLAN) networks, 3G networks are wide area cellular telephone networks which evolved to incorporate high-speed internet access and video telephony. IEEE 802.11 networks are short range, high-bandwidth networks primarily developed for data.

The ITU has not provided a clear definition of the speeds users can expect from 3G equipment or providers. Thus users sold 3G service may not be able to point to a standard and say that the speeds it specifies are not being met. While stating in commentary that "it is expected that IMT-2000 will provide higher transmission rates: a minimum speed of 2Mbit/s for stationary or walking users, and 348 <sic> kbit/s in a moving vehicle", the ITU does not actually clearly specify minimum or average speeds or what modes of the interfaces qualify as 3G, so various speeds are sold as 3G intended to meet customers expectations of broadband speed. It is often suggested by industry sources that 3G can be expected to provide 384 kbit/s at or below pedestrian speeds, but only 128 kbit/s in a moving car. While EDGE is part of the 3G standard, some phones report EDGE and 3G network availability as separate things, notably the iPhone.

The Advantages of 3G

The Advantage that 3G tends to have when compared to all earlier forms of next generation mobile communications systems is an improvement in bit rate.  The higher bit rate capabilities have brought about a move in service providers to indulge into producing  many bandwidth intensive applications that would not have been conceived of otherwise.  There are 2 forces bringing about the improvement of these 3G systems.  The first being the need for higher data rate services, such as high-speed wireless Internet access.  The second being more efficient use of the available radio frequency (RF) spectrum.  The second is a consequence of the projected expansion in worldwide usage of wireless services.

Benefits also include packet-based data offers a number of advantages over the existing circuit-switched methods used for transporting mobile voice.  It allows increased call volumes and support for multimedia data applications, such as video and photography.

Consumers will be charged on the quantity of data they transmit, not on how much time they are connected to the network, while with 3G you are constantly online and basically pay for the information you receive.

While third-generation packet based networks will allow users to be online all the time the capability for new applications is huge.

Answer 4

3G is third generation cell phone technology. its real name is WCDMA a better version of GSM. 3G give u faster internet and the voice quality is generally better and it doesnt give u that noise if ur near speakers either. also it gives u the ability to do better thigns like watch videos or tv or videocall people.
