The QHM-21 is a portable HSUPA USB modem. When plugging into a USB port of a PC (Notebook), the QHM-21 with a build-in SIM card allows users to access internet with 3G telecom network. The QHM-21 utilizes dual antennas that improve signal reception. Inspired by ladybugs, the antennas can be swung open or retracted like a ladybug's wings, with one touch on the button, to activate the wireless connection. The design creates an interesting association of "free wireless connection" with "careless flying of a ladybug". This slim and compact device also serves as a portable USB flash drive.
