@berstern - Thanks for the comment!

Good timing - We are actually exploring options to allow for a built-in cellular connection on the mcGateway. Not sure of the timeline of this right now but it would be great as it means you can then deploy the mcGateway anywhere and start to collect data from your mcDevices.

Keep in mind that you can do this today, you just require a cellular Ethernet or WIFI modem which you can then connect to the mcGateway. We've done some testing with some inexpensive ones available on Amazon and you can also look for options with your local mobile company.

USB to output data - No, the USB is strictly for powering the gateway and the USB port (only on the mcGateway110) is meant for updating the device to the latest mcOS (firmware). the new mcGateway120 does not have a USB port as it receives new mcOS directly from our new mcCloud system!
You can learn more about the soon to be released mcCloud system here: https://portal.mcthings.com/

and here: https://www.mcthings.com/getting-started-mccloud/

mcCloud will be released very soon and we are going to offer any existing users who have legacy hardware (mcMod110's and mcGateway110's) the option to upgrade to new hardware at a discounted price. Keep an eye out for this announcement on the forum and in your email!
Hope that helps, let us know if you have any other questions
