Mobile network operators are projected to invest more than $1.1 trillion in their networks over the next five years, and about 80% of that will be in 5G technology, according to a new report from GSMA Intelligence. The industry is putting a lot of time and money into the next generation of wireless technology, even as LTE only became the dominant network technology last year. 2019 was the first year when LTE connections accounted for more than half of mobile connections, hitting 52%; that figure for LTE connections is projected to hit 56% by 2025.
