2G (GSM) vs. 5G (NR)
Comparing 2 standards across 16 specifications. 16 key differences identified.
2G (Second Generation Cellular) revolutionized mobile communications in 1991 by transitioning from analog 1G to digital TDMA/FDMA. Governed by 3GPP GSM standards, it introduced Subscriber Identity Module (SIM) cards, SMS text messaging, GPRS packet data (up to 114 kbps), and 8PSK-modulated EDGE (up to 384 kbps).
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).
