MikroTik mAP lite
The mAP lite is the smallest wireless access point. It is barely larger than a matchbox, it's even has to use a special Ethernet port to match it?s slim profile. You can carry it anywhere: use as a travel router to extend that hotel internet to all your devices, or as a client device to improve your laptop signal range, the tiny mAP lite will be always with you. It can also serve as a simple configuration tool for your servers, if there is no ethernet on your mobile device. The mAP lite is a dual chain 802.11 b/g/n device and operates in 2GHz.
