TrendNet (http://www.trendnet.com) has released what it says is the world’s smallest wireless N USB adapter: the 150Mbps Micro Wireless N USB Adapter. It measures 0.59 x 0.74 x 0.28 inches and has a manufacturer’s suggested retail price of US$39.99.

When plugged into a USB port, the adapter extends a scant 0.3 inches (0.8 cm) from the edge of the computer, says Sonny Su, technology director for TrendNet.. The adapter is so small that users can stow a laptop with the adapter plugged in, without worrying about damaging the laptop or the adapter, he adds.

This adapter is also the only product in its class that features a convenient WPS button, according to Su. One-touch Wi-Fi Protected Setup, or WPS technology, eliminates the hassle of entering complicated codes in order to connect to a wireless network, he adds. Simply press the WPS button on a compatible router (most TrendNet routers feature a WPS button), then press the WPS button on TrendNet’s 150Mbps Micro Wireless N USB Adapter, confirm that you want to connect, and you’re connected.
