I got a very small and light Wi-Fi router that can unwire usual LAN system.
At a hotel or somewhere outside especially during an overseas business trip, in many cases Wi-Fi service is not available.
However, by connecting this router to an equipped LAN port in the room, I can use my iPhone with Wi-Fi anywhere, which would provide hi-speed access to the internet and, happily, would reduce the global roaming cost.
Of course, it can also be used as a router.
