The first batch of 5G phones is right around the corner , but Qualcomm is already preparing for the follow-up. It's introducing a Snapdragon X55 modem that should make 5G more viable in the real world. Unlike the X50 , the new chipset will support "all major frequency bands" for ( millimeter wave or lower), different operation modes and network deployments (including 4G/5G spectrum sharing), effectively supporting most any 5G rollout on the horizon. You'll be more likely to get coverage beyond your home network, and shouldn't be left behind if there's a coverage upgrade.
The X55 is fast, too, promising 7Gbps peak download speeds and 3Gbps uploads in ideal conditions.
Crucially, it should lead to slicker devices. The 7-nanometer manufacturing should help with the X55's power efficiency from the get-go, but it's also using tricks like 100MHz envelope tracking and adaptive antenna tuning to minimize the electricity draw when you're on a 5G network. You shouldn't need a large handset or a bulky add-on just to enjoy better-than-LTE speeds.
Device makers already have samples of the X55, and the modem is poised to reach shipping hardware sometime in late 2019. In essence, Qualcomm is giving you a clue as to when 5G will become truly practical. The X55 should usher in a second wave of 5G phones that don't have to make extensive compromises in the name of speed.
