Filing this under concepts, HP has seen the future of mobile devices in the year 2016, and is unveilling a concept that connects all your gear with one very fashionable wrist band. The Hub is a watch that communicates with your mobile using Bluetooth, or Wi-Fi. According to Cnet Uk, "users would set up a personal area network using ultra wideband
(UWB), but also Bluetooth if they were still using today's devices. All the
radios for external connectivity -- whether 3G, Wi-Fi, WiMax or any other bearer
-- would be contained in the hub."
WiMax is probably a fantasy for technical reasons..HP’s Personal Wrist Hub is a great innovation of a mobile devices in the future..
