Then comes the 2G technology which uses digital signal transmission technology with time division multiplexing technique (TDMA) and code division multiple access technique (CDMA) .
Read moreWhat modulation is used in 1G?
The first generation mobile systems are based on analog technology. The first technology uses frequency modulation (FM) and frequency division duplexing (FDD), frequency division multiple access (FDMA) . The common signalling channels were used in first generation cellular systems.

THIRD GENERATION (3G) 3G network combines aspects of the 2G network with new technologies and protocols to deliver a significantly faster data rate . By using packet switching, the original technology was improved to allow speeds up to 14 Mbps. It used Wide Band Wireless Network that increased clarity.
Read moreWhat spectrum is used for 3G?
Most 3G networks operate in the 800 MHz, 850 MHz, 900 MHz, 1,700 MHz, 1,900 MHz and 2,100 MHz bands . “The 3G networks eventually led to a dramatic growth in the use of mobile data, initially through USB dongles connected to laptops, and later through widespread smartphone adoption.”
Read moreWhat is the difference between 2G and 3G LTE?
2G – Delivered digital signal and offered up to 250Kbps speed. Supports voice, text and data services. 3G – At least 200Kbps up to 3Mbps speed . 4G – 4G delivers up to 100Mbps for mobile access, and up to 1Gbps for wireless access.
Read moreWhat is 2G and 3G spectrum?
The amount of spectrum used for the transmission of a radio signal. For example, a 2G (GSM) channel is 200 kHz wide, a 3G (WCDMA) channel is 5 MHz wide and a 4G (LTE) channel can be up to 20MHz wide.
Read moreAre 4G and 5G on different frequencies?
5G Works Differently Than 4G 4G uses frequencies below 6 GHz , while some 5G networks use higher frequencies, like around 30 GHz or more. These high frequencies are great for a number of reasons, one of the most important being that they support a huge capacity for fast data.
