Need to know: Real 5G speeds and spectrum (3 minute read)

Takeaway: 95+% of 5G is lowband (< 1800 MHz or mid-band (2500-4200 MHz.) Asia, TMobile US, and much of Europe is mid-band.80-200 MHz of spectrum usually delivers 100-400 Mbps. Low-band (AT&T, much of DT & other European, runs at 4G speeds and sometimes lower. See AT&T data below.Millimeter wave often does 500 Mbps and...

Need to Know: 5G Spectrum – Think mid-band

Takeway: Decent 5G until around 2025 will be mostly mid-band, 2500-4200 MHz. Frequencies lower than 2100 MHz essentially deliver 4G capacity. Millimeter wave, 20 GHz and above, can deliver gigabits but will be rare until the middle of the decade or later. It’s expensive, and the carriers don’t see much market. Heretical but true:...

5X Advance for Africa with Massive MIMO, Spectrum

In 2014, Stanford Professor Paulraj told me MU MIMO would be the most effective way to deliver the capacity Africa needed. In 2016, the first Massive MIMO systems were deployed by Softbank Japan and China Mobile. The results were excellent. Softbank reported “up to a 10X improvement.” Huang Yuhong of China Mobile told me...
