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.
Read moreWhat frequencies are used for 4G?
Early cellular networks, including 1G, operated at a frequency of 850 MHz and 1900 MHz. Then, 2G and 3G networks operated at additional frequency bands and spectrum around 2100 MHz, and 4G LTE technology operated at additional frequency bands and spectrum around 600 MHz, 700 MHz, 1.7/2.1 GHz, 2.3 GHz, and 2.5 GHz .

Wifi transmits data at 2.4 GHz and 5 GHz radio frequencies. Whereas 3G transmits data at low frequencies ranging from 850 MHz to 1900 MHz .
Read moreWhat frequency does WiFi use?
For WiFi this frequency happens to be 2.4Ghz and 5Ghz . These waves are very similar to the frequency found in your microwave! Your microwave uses 2.450Ghz to heat up food and your router uses 2.412 GHz to 2.472 GHz to transmit your data over WiFi.

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.
