Both the airRouter and airRouter-HP have:
     1. One "Main Eithernet Port" which is used to connect to the internet by connecting to your home router.
     2. Three Eithernet ports (1, 2, and 3) for connecting services such as a computer, VOIP phone, or camera.
     3. One (dtd) Device-to-device port (port 4) that can only be used to connect your airRouter to another AREDN node.
     4. One USB port that can be used to plug in a USB memory stick or USB external disk drive.  At this time, a firmware patch is required to enable the USB port.
The main differences between the airRouter and airRouter-HP are:

     1.  The airRouter is powered by a 5V/2A wall wart power adapter into the power in port while the airRouter-HP is powered by a Power-Over-Ethernet (POE) adapter into the Main Ethernet Port.  I have seen both 5V/2A POE adapters with a wall wart type adapter (as in the User Guide) as well as a 24V/0.5A POE similar to the ones used for powering a bullet (as in the Quick Start Guide).  Check the label on the bottom of the airRouter-HP for power requirements.

     2.  The airRouter uses an internal antenna and the airRouter-HP comes with a removable (RP-SMA) antenna.

     3.  With the AREDN firmware installed the airRouter power level can be set at 2-20 dBm while the airRouter-HP (5V/2A version) power level can be set at 8-26 dBm, and the airrouter HP (24V/.5A version) power level can be set at 10-28 dBm.  At this point I don't know if the radio actually puts out more power to the antenna or if it is taking into consideration the additional 6 dBi gain of the stock external antenna.
