2.3. GSM uses a digital modulation format called 0.3GMSK (Gaussian minimum shift keying) . The 0.3 describes the bandwidth of the Gaussian filter with relation to the bit rate. GMSK is a special type of digital FM modulation.
Read moreWhat are 1G 2G 3G 4G and 5G mobile network technologies?
1G, 2G, 3G, 4G and 5G are the five generations of mobile networks where G stands for Generation, and the number denotes the generation number . 5G is the latest generation, whereas 1G networks are now obsolete. The cellular technologies GSM, UMTS, LTE and NR enable 2G, 3G, 4G and 5G, respectively.
Read moreWhat are the principles of cellular network?
The coverage area of cellular networks are divided into cells, each cell having its own antenna for transmitting the signals. Each cell has its own frequencies. Data communication in cellular networks is served by its base station transmitter, receiver and its control unit.
Read moreWhat is generation of cellular network?
A. The cellular communications networks are known by their numeric generation : 1G, 2G, 3G, 4G and 5G. We are currently fully deployed in 4G with 5G gaining ground.
Read moreWhat are the differences amongst 2G 3G 4G and 5G networks?
4G is more spectrally efficient than 3G, just as 5G is more spectrally efficient than 4G . Each generation delivers more data per hertz than the previous one. 3G works at frequencies up to 2.1Gigahertz, 4G up to 2.5Gigahertz and 5G can be up to 95 Gigahertz. That is why there is a lot of hype around 5G.
Read moreWhat are LTE technologies?
LTE (Long Term Evolution) is the project name given to development of a high performance air interface for cellular mobile communication systems . It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks.
Read moreWhat is the difference 2G 3G 4G?
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 .
