Great work! I've used a TL-MR3020 myself. It's a nice tool to have in the bag. I've done "HamWAN portable" with essentially this same kit in a backpack while hanging off a tower--the wifi makes it possible to use a cellphone to check signal strengths while aiming a dish.
* Mikrotik has some cellular modem support via USB, but I haven't tried it on the mAP... It might be possible.
Do you have any plans for a permanent installation? I know one thing I don't want to have to deal with during a disaster: setting up a HamWAN link.
