By 2021, it's estimated that more people will have mobile phones (5.5 billion)
than running water (5.3 billion). Bandwidth-hungry video will further increase
the demands on mobile networks, accounting for 78% of mobile traffic.

5G
networks using massive multiple-input, multiple-output (MIMO) technology will
be key to supporting this growth. It's expected that 5G mobile connections
will grow from just 5 million in 2019 to nearly 600 million by 2023, according to
Strategy Analytics.
