Mobile operator Three (3) UK has announced the launch of an interesting new Mobile Wi-Fi device (for some reason they call it a 'service') - also known as MiFi, which is essentially a battery powered Wi-Fi router that has been designed to distribute the operators Mobile Broadband ( 3G ) service over a Wi-Fi link.

Set-up is simple. No software installation is required. Simply switch on the wireless modem (just 86 x 45 x 10 mm in size) and connect to the Mobile Internet using a Wi-Fi signal. A Wi-Fi enabled device will automatically pick up the signal and ask for an eight-digit network key which you will be asked to input just once for every new device you want to connect.


The device essentially acts as a replacement for more traditional USB Modems (Dongles), which can only plug into one computer at a time. Unlike those the MiFi router can connect to multiple computers and you could even situate it near a window, which could improve Mobile Broadband reception around the home or office.


Unlike USB Modems the MiFi device, which has yet to be given a price but will be released in time for Christmas, lacks the ability to add extra storage via MicroSD memory cards; a common feature of most new USB Modems.
