The mAP (micro Access Point) is a tiny size wireless Dual-Chain 2.4GHz Access Point with full RouterOS capabilities.
It is very portable since it accepts power from a wide variety of sources, including USB, passive PoE, and a power jack.
It also works as a PoE injector; the second Ethernet port provides up to 500 mA of power to another device; for example, you can connect a SXT CPE device to it.
