This is brilliant, especially if you are already invested in the Ubiquiti/UniFi Ecosystem. There was a UniFi Teleport, and I think that function is now part of this Travel Router. From the video and the images, I believe this can also be added to a car act as a family wi-fi on the move.
I’ve always had a Pocket Travel Router (along with a thin but long enough RJ45 cable) with me while traveling, starting with the D-Link AC750 Travel Router. It does away with Wi-Fi Change, and all of your devices just continue to work, no worry about syncing, file-transfers, etc. A travel router becomes even more convenient when traveling with the family.
