What is the comparison between 2G 3G and 4G architecture?
The speed increases and the technology used to achieve that speed also changes. For eg, 1G offers 2.4 kbps, 2G offers 64 Kbps and is based on GSM, 3G offers 144 kbps-2 mbps whereas 4G offers 100 Mbps – 1 Gbps and is based on LTE technology .
What is 3G network architecture?
Third generation (3G) mobile networks define three components of the overall path from mobile station to IP network: the radio frequencies used, the air interface options used between the mobile device and base station, and the entire network architecture, including interfaces between components.
What is the difference between 2G 2.5 G and 3G describe GPRS architecture?
3G typically operates in separate frequencies than 2G and 2.5G uses, thus allowing mobile phones to switch from one to the other when capable. 2.5G implements packet switching along with the circuit switching in 2G. 2.5G has much faster data rates than 2G.
What is GSM GSM and architecture?
The GSM architecture consists of three major interconnected subsystems that interact with themselves and with users through certain network interface. The subsystems are Base Station Subsystem (BSS), Network Switching Subsystem (NSS) and Operational Support Subsystem (OSS).
What is GSM and its architecture?
GSM is an open and digital cellular technology used for mobile communication. It uses 4 different frequency bands of 850 MHz, 900 MHz, 1800 MHz and 1900 MHz . It uses the combination of FDMA and TDMA. This article includes all the concepts of GSM architecture and how it works.
Which is not part of GSM architecture?
Which of the following does not come under subsystem of GSM architecture? Explanation: NSS (Network and Switching Subsystem) manages the switching functions of the system. It allows the MSCs to communicate with other networks such as PSTN and ISDN. 11.
What is the 2G GSM network architecture?
The 2G GSM network architecture follows a logical method of operation. It is far simpler than current mobile phone network architectures which use software defined entities to enable very flexible operation. However the 2G GSM architecture does show the voice and operational basic functions that are needed and how they fit together.
What is the difference between 2G and 3G mobile phones?
This means that your 3G mobile phones cannot communicate with GSM towers and 2G phones cannot communicate with 3G towers. To preserve backwards compatibility, most telecoms install newer 3G radios while still maintaining the older GSM radios. Mobile phone makers also include 3G support into their phones without removing 2G technologies.
What are the disadvantages of 3G technology?
The only drawback behind 3G technology is the fact that it is not backward compatible to the older GSM technology. This means that your 3G mobile phones cannot communicate with GSM towers and 2G phones cannot communicate with 3G towers.
Can 2G and 3G use the same antenna?
For 2G, 3G, 4G, Bluetooth, etc. Since the “Gs” are similar in the way they operate, they can use the same antenna. Bluetooth and WiFi operate very differently and require different antennas as can be seen in the teardown.
