3G
3G
The third generation of mobile telecommunications technology, providing data rates up to 42 Mbps via HSPA+ and enabling mobile broadband, video calling, and internet access over cellular networks
Understanding 3G
3G networks operate in frequency bands between 700 MHz and 2600 MHz, using WCDMA and CDMA2000 air interfaces. The technology introduced packet-switched data alongside circuit-switched voice, enabling simultaneous voice and data transmission.
Key 3G standards include UMTS (Universal Mobile Telecommunications System) in Europe and Asia, and CDMA2000 in North America. HSPA and HSPA+ enhancements pushed theoretical peak rates from the original 384 kbps up to 42 Mbps downlink.
