Huawei has announced what it's claiming as the world's fastest MiFi, or mobile Wi-Fi, in the Huawei E5786, at Mobile World Congress 2014 in Barcelona.

The new MiFi device will offer Cat 6 LTE, with download speeds up to 300Mbps and upload speeds of 100Mbps, but of course, you'll need the mobile phone network to support that.

Not only does the E5786 offer blazing mobile network speeds, but it will also give you the latest dual-band Wi-Fi 802.11ac, and support for up to 10 connected devices.

There's a capacious 3000mAh battery for the E5786 that will give you 10 hours of use and also offers reverse charging, meaning that if your smartphone is running low, you can charge it from your MiFi.

The Huawei E5786 will appear in the second half of 2014, but Huawei told us it will depend on network roll-out to support the speeds it offers. - PAY MONTHLY PHONES The Samsung Galaxy S10+ is now available on EE who have been awarded the UK’s best network for the fifth year running. RootMetrics tested the four UK networks and EE was faster and more reliable than all of them, with better data performance. Their network has come a long way since they launched in 2012. Back then they had 11 UK cities covered by 4G. Today they cover most of the UK’s land mass, thanks to 19,000 state-of-the-art 4G sites. They’ve got faster, too – from 50Mbps to a maximum speed of 400Mbps. And they’re soon to experience even greater possibilities with the launch of 5G.
