The 16-beam spatial-multiplexing technology consists of eight analog, front-end processing, low-power units to form 16 beams and a multiple-input multiple-output (MIMO) digital processing algorithm to reduce inter-beam interference. The new system's realizes the gain of 4,096 antenna elements while its computational complexity is just that of 16 antenna elements. The new mobile telecommunication system operating at 28GHz yielded spectral efficiency of 63.7bps/Hz2 and a downlink transmission rate of 25.5Gbps, both believed to be world's firsts, with 500MHz bandwidth for one user device.

Time occupancy for downlink transmission is assumed to be 80% during the transmission interval. The remainder of the interval is used for uplink transmission.
The two-beam massive MIMO antenna RF module includes two active phased array antenna (APAA) units operating at 28GHz, each consisting of densely integrated 256 antenna elements and RF devices. The RF module's thickness of just 7cm, roughly one-third that of a predecessor unit, will enable easy installation for wide deployment of 5G systems.
