From 19 November US AT&T subscribers will be able to buy the world's first mobile data hotspot to feature both 4G LTE support and the unusual innovation of a built-in 2.8 inch colour LCD touchscreen, the company has announced.

Announced last month by portable hotspot pioneer Novatel Wireless, the MiFi Liberate router is claimed to offer simple, finger-driven setup for 10 devices to share the same 4G Internet connection via 802.11n Wi-Fi.

Admins can also check data usage through the router's interface as well as set it up for DLNA media sharing and configure the way sharing devices (smartphones and laptops) use the connection, including configuring the integrated firewall.

The built-in battery is said to last for up to 11 hours while owners can add storage and file-sharing capacity via a microSD card slot with a maximum capacity of 32GB. As with previous models, owners place their SIM in a separate slot.

The Liberate is a bit ahead of the curve when it comes to mobile data, used by only a fraction of current mobile users; in the UK only the EE 4G network is up and running so the device's potential will be limited to one set of subscribers for the foreseeable future.

What this all costs will vary by network and country; AT&T is offering it to subscribers using its 4G service for $49.99 on a two-year agreement. Prices for the device bought standalone have not been made available.
