Increases in monthly mobile data usage show no signs of slowing.

North America may be a mature market where most people likely to buy a mobile phone already have. But the way we use those phones continues to change rapidly with explosive growth in data consumption.
It estimated the quarter's monthly traffic at about 5.7 exabytes -- more than 5 million times the storage space on a mode PC hard drive. Video, social networking and audio streaming are the top tasks for data usage.
To get an idea of why carriers have such a hard time keeping their networks up to scratch, note that during the same quarter five years ago, there was only something like a third of an exabyte of traffic. And more is coming: "Between 2015 and 2021, there will be 12X growth in smartphone traffic," Ericsson said.
North Americans were the biggest data consumers, using about 4GB of data per phone per month on average. Ericsson forecasts that in 2021, that'll surge to about 22GB per phone per month, so keep an eye on how close you're getting to your monthly limits. Weste Europeans only use about half as much today, but they'll mostly catch up in the next five years, Ericsson said.
North Americans use the most data per phone, but the rest of the world is closing the gap.

Ericsson also issued early forecasts for the shift from today's fourth-generation (4G) mobile network technology, called LTE, will begin in eaest next decade with they arrival of the first 5G networks. They'll bring faster speeds and lower battery usage starting in 2020 and reach 150 million subscribers in 2021.
Many people will use 5G not for phones, but rather as an alteative to fixed phone, cable, or fiber-optic lines for broadband, though. Fixed-line broadband should barely budge in the next year while mobile broadband subscriptions surge from about 1 billion to 7.5 billion.
