It was impossible to walk 10 feet at MWC this year without seeing '5G' written on something. We even saw a '5G Ambulance.'

Much of this feels like companies leaping aboard the buzzword bandwagon. But one device with immediate real-world practicality is the HTC 5G Hub. At its simplest, this is a portable Wi-Fi router, like the 4G models you already know.

But of course it has 5G, which means incredible fast download speeds (as in, an HD movie in five seconds), very low latency — key for gaming and virtual reality — and the ability to stream 4K video wherever you are. Up to 20 devices can be connected at once, which will feel like bringing a fast home fiber connection with you on the go.

An integrated 7,660mAh battery is good for up to three days of 5G connectivity, HTC told us, and there's a USB-C port so hooking up a wall plug or portable battery is easy. The Hub, which will be offered via Sprint in the US in the next couple of months, runs Android 9 and has a 5-inch touch screen for easy set-up and use.
