Third-generation cellular technology, otherwise known as 3G builds on the advancement of the 2.5G networks to support higher throughput and speeds of data transfer. This enables 3G network operators to deliver a wider range of services including: Mobile internet access. Voice over internet protocol. Video calls.

3G Technology. The 3G network is named UMTS – Universal Mobile Terrestrial or Telecommunication system. 3G has a data rate of 384 kbps whereas for EDGE the data rate is about 170 kbps and for GPRS the data rate is 56 to 64 kbps. This network is also having a feature of video calling.
VOLTE can carry 3 times more data than 3G UMTS network and 6 times more data than 2G GSM network. Every new generation of wireless networks delivers quicker speeds and additional functionality 2G – Second generation communication system GSM. The second generation of mobile communication systems introduced a new digital technology for wireless transmission, also known as Global System for Mobile Communication (GSM). GSM technology became the base standard for further development in wireless standards later.
GEA/4: used for GSM GPRS/EDGE/3G/4G, 128-bit keylength, 128-bit state, based off KASUMI. This list covers only global implementations of "2G", "3G" and "4G" mobile networks, and does not include TETRA and IDEN. Help and corrections to this list would be very appreciated.

The maximum distance at which the interference observed for 2G cellular phone and 3G cellular phone is 1.5 m and minimum distance at which interference observed for 2G cellular phone, and 3G cellular phone is 0.5 and 0.35 m, respectively. Ultrasound equipment is the device affected by both 2G and 3G cellular phones at greater distance.
0. GSM uses FDD (frequency division duplexing) and provides separate channels for uplink and downlink. I found however, in this link, that the mobile station does not receive and transmit at the same time. Also, in the link, a good explanation is provided about why we would need different channels in that case.
African countries have begun retiring legacy networks – 2G and 3G – as the continent’s burgeoning digital economy raises the demand for faster and more efficient internet connectivity. Spectrum auctions, mobile financing arrangements and the mass roll-out of 5G networks are all seen accelerating the shift to high-speed networks across key
GPRS or General Packet Radio Service is a GSM enhancement introduced in 2000 to facilitate packet-switched mobile data. GPRS is a 2G technology for the GSM mobile network evolution track; however, the network nodes it introduced are also used in 3G UMTS networks. Recent mobile networks, including 4G LTE and 5G New Radio (NR), are fully packet
To check the 2G signal strength value of your RUT device, log in to your router's WebUI and go to the Status -> Network -> Mobile window: 3G (WCDMA, TDSCDMA, CDMA, EVDO, CDMA-EVDO) For 3G service mode, there are three relevant measurements: RSSI - Received Signal Strength Indicator. RSSI is a negative value, and the closer to 0, the stronger
2G (GSM, Global System for Mobile Communications) and 3G (UMTS, Universal Mobile Telecommunication Systems) have served the industry well for a long time. An estimated half of all IoT devices deployed worldwide used these frequencies to transmit data between machines or end devices until the 2G and 3G shutdowns. But that will soon come to an end.
GEA/1 and GEA/2: Rather insecure encryption algorithms covering the entire GSM/GPRS/ EDGE/3G/4G spectrum, which can be easily decrypted. GEA/3 and GEA/4: Similar to the A5/3 and A5/4, the GEA/3 is based on the 64-bit version of KASUMI, while the GEA/5 offers the advanced 128-bit version. Both cover the full cellular spectrum GSM/GPRS/EDGE/3G/4G.

G 2G 3G 4G are not bands or frequency spectrums per-say. GSM (2G) is on it’s way out, but 3 and 4G “GSM” are still a thing, sort of – it just isn’t typically called GSM, but HSP(D)A
