After months of hype about instant connectivity and super-speed downloads, the next generation of wireless service will finally become a reality in 2019.

All four major U.S. carriers have vowed to kick off or expand their respective 5G networks in the coming year, and most major phone manufacturers are set to release their first 5G-enabled phones (Apple, the reported exception, is said to be waiting until 2020 to bring 5G to the iPhone).

While many of next year’s fledgling efforts may not live up to the technology’s loftiest expectations, 5G is expected to eventually reach download speeds between 10 and 100 times faster than what’s currently available, with a load lag time of less than a millisecond. Experts say that kind of unprecedented interconnectivity could usher in a host of new emerging tech markets, ranging from driverless car communication and power grid administration to mixed-reality streaming and remote healthcare.
