China, Oct. 27 -- Huawei has verified its sub-1 GHz (700 MHz, 800 MHz, and 900 MHz) Massive MIMO, the first of its kind, for commercial use. The results highlight a ground-breaking leap in the spectral efficiency of sub-1 GHz bands, and this product's superior performance over conventional low-band 2T2R equipment: five-fold higher downlink capacity, 8 dB better uplink coverage, and four-fold higher uplink speeds. These achievements represent a major step forward in bringing sub-1 GHz Massive MIMO from research to commercial deployment.Huawei's sub-1 GHz Massive MIMO is the first product in the industry to combine extremely large antenna arrays with wideband technology in the prized low-band spectrum. This breakthrough intelligently aggregat...
