Trendnet launches its TEW-648UBM-- a small 150Mbps Wireless N USB adapter. It measures only 1.5 x 1.9 x 0.7 cm.
The adapter is ideal for laptops. Once plugged into USB port the adapter extends only 0.8cm from the machine's edge.
Trendnet says its device is the only product in its class with a WPS button. Users press the compatible router's WPS button and then the adapter's button, before confirming connection.
