D-Link's DWR-830 Mobile Wi-Fi Hotspot 42 Mbps uses your 3G DC-HSPA+ Internet connection to give you a simple & fast Wi-Fi network anywhere you need one. Instead of being confined to one Internet-connected device through a USB (Universal Serial Bus) dongle, the DWR-830 means that you can create & share Wi-Fi hotspots anywhere you have a 3G signal. The compact size means you can conveniently take it with you & share your connection anywhere; use it in a cafe to send e-mails while your friend reads the news, or have your laptop, phone, & tablet all connected to the Internet at the same time using just one mobile Internet service.
