What is eMBB?
eMBB is one of the three primary 5G use case categories defined in ITU-R’s IMT-2020 framework. It targets significantly higher data rates, greater network capacity, and improved spectral efficiency compared to 4G LTE — with a peak downlink target of 20 Gbps and an average user throughput improvement of 10–100x over LTE.
How Does eMBB Work?
eMBB exploits wide bandwidths (up to 400 MHz per carrier in FR2), Massive MIMO for spatial multiplexing, carrier aggregation to combine multiple bands, and high-order modulation (256-QAM in Release 15, 1024-QAM in Release 16). Network densification with small cells overlaid on macro cells boosts capacity in high-traffic areas.
Use Cases
8K video streaming, immersive AR/VR and cloud gaming, fixed wireless access (FWA) replacing home fibre, stadium and event venue gigabit connectivity, mobile video production.
3GPP / Standards Reference
ITU-R Recommendation M.2083 (IMT-2020 Vision), 3GPP TR 38.913 (5G NR Requirements)
