Which technique is used in 3G?

Which technique is used in 3G?

QPSK modulation principle. This modulation technique is used in 3G system.

Which are the main features of 3G network?

Some of the main features of 3G are:

• Speed of up to 2 Mbps.
• Increased bandwidth and data transfer rates.
• Send/receive large email messages.
• Large capacities and broadband capabilities.

What are the two main 3G cellular technologies?

This led to the establishment of two distinct 3G families: 3GPP and 3GPP2. The 3rd Generation Partnership Project (3GPP) was formed in 1998 to foster deployment of 3G networks that descended from GSM. 3GPP technologies evolved as follows: General Packet Radio Service (GPRS) offered speeds up to 114 Kbps.

How mobile location is measured in cellular network?

It is possible to locate the position of a mobile station by measuring the Time of Arrival (TOA) or angle of arrival (AOA) of a signal at multiple locations [2]. The transmitting mobile stations location is estimated by combining measurement from multiple base stations through triangulation method.

Which multiple access techniques is used in 3G mobile network?

Third generation cell phone technology uses code division multiple access (CDMA). 4G cellular communication system uses advance version of FDMA scheme i.e. OFDMA (Orthogonal Frequency Division Multiple Access). This generation uses packet switching method for data transmission.

What are the modulation techniques used in 2G 3G 4G?

The technology behind the Global System for Mobile communication (GSMTM) uses Gaussian Minimum Shift Keying (GMSK) modulation a variant of Phase Shift Keying (PSK) with Time Division Multiple Access (TDMA) signalling over Frequency Division Duplex (FDD) carriers.

What is the multiple access technique used in a 3G mobile network?

What are 3G technologies?

3G is the third generation of wireless mobile telecommunications technology. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV.

Which multiple access technique is used in 3G?
