3G (UMTS) vs. 5G (NR)
Comparing 2 standards across 15 specifications. 15 key differences identified.
3G (Third Generation Cellular) established mobile broadband in 2001 under the ITU IMT-2000 framework. Utilizing Wideband Code Division Multiple Access (WCDMA) in 5 MHz channels, it evolved from 384 kbps basic UMTS to 42 Mbps DC-HSPA+ (High Speed Packet Access), enabling mobile web browsing, video calling, and app store ecosystems.
5G New Radio (5G NR) is the global 3GPP standard (Releases 15–18) for fifth-generation cellular communications. Operating across Sub-6 GHz (FR1) and Millimeter Wave (FR2: 24–71 GHz) frequency bands, it introduces flexible numerology, Massive MIMO beamforming, and network slicing to deliver enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and massive IoT (mMTC).
