5G (NR) vs. 6G
Comparing 2 standards across 14 specifications. 14 key differences identified.
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).
6G (Sixth Generation Cellular) is the future mobile communications standard targeted for commercialization around 2030 under the ITU-R IMT-2030 framework and 3GPP standardization. Envisioned to utilize Sub-Terahertz (100 GHz–1 THz) spectrum, 6G introduces Integrated Sensing and Communication (ISAC), native AI air interfaces, and sub-100 microsecond latency.
