It's much more than a simple hotspot, but too bulky to be a smartphone and too small for a tablet. But that does not matter, because HTC has made the impossible possible with the new 5G hub and created a hotspot worth taking care of.
Usually hotspots are a one-off purpose. They turn them on, connect to a cellular connection, and then tap that information on a phone or PC (usually over Wi-Fi). Very boring.
But with the upcoming arrival of 5G networks, HTC partnered with Sprint, wondering what a hotspot might be when connected to mobile data supporting speeds of 1 Gbps or more, and super fast latencies.  This is far more ports than a normal hotspot. The 5G hub even offers two ways to charge the device (the round AC port and USB-C with Qualcomm Quick Charge 3.0.
A simple puck with an on / off switch.) HTC added There are a number of features added to the 5G hub, including a 5-inch screen, a lock button, a microSD card slot, 802.11ad Wi-Fi, ports for Ethernet and USB-C, and even a full build of Android 9 Pie with the 5G hub being crowned by a Qualcomm Snapdragon 855 processor and an X50 modem (the same chip and modem that is also used in the new Samsung Galaxy S10 5G and LG V50 5G) the 5G hub should also be quite fast.
You can do normal hotspot activity like tracking data usage and see how many devices are connected to it via the screen of the 5G hub, but since Android runs on built-in stereo speakers, you can also all your favorite apps in stabling, streaming movies and listening to music. If you like, you can even use Chromecast to send videos wirelessly to a nearby TV or use a USB-C cable to view the cable if Chromecasting is out of the question.
This basically makes the 5G hub a portable medium and gives people forced to work out of hotel rooms the opportunity to watch their favorite shows in the background on a secondary device. While the 5G hub only has 4GB of RAM and 32GB of storage, the latter can always be upgraded thanks to the microSD expandability of the hub.
At MWC, I also tried one of the more distant uses of the 5G Hub, where a server-hosted session was streamed from Superhot VR to a nearby VR headset via WiGig. This was the first scenario that made the idea of cloud gaming over 5G appealing to me, because when I'm on the road, I do not want to bring a laptop or desktop strong enough to play VR games. And with the 5G hub, that's no longer a problem.
HTC has even provided the 5G hub with a sizeable 7,660 mAh recharged battery so you can quickly charge other devices with its extra power. The hub can not provide your devices with super-fast data, they can also be powered. I wish HTC could have improved a little, the Hub's 5-inch screen only offers a resolution of 1280×720. That's not even high enough to qualify as Full HD.
It's also worth noting that the 5G hub is noticeably larger, if still portable, than the pluggable hotspots like a Verizon Jetpack.
Because Sprint's The 5G network will only be switched on in late spring (probably in May). There are no official pricing or availability information yet. Since traditional 5G phones are likely to cost a coin, HTC's 5G hub may be the best way to experience 5G networks in 2019 without having to completely overhaul all mobile devices.
