Online access Backup alternative for the small office

People moving into the new office but the network gear may not be ready yet.  Looking for a quick alternative for WiFi access just so users can go online.  
Saw that thread below from 2015 where a person says they ran office of 30 off this device following hurricane Sandy.
My office would be about 10-12 people day one.

Would that work as a temp solution?  Any suggestions appreciated.  Thanks!!

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Looks like it should work, but try to see if you can project how long you'd need that connection for. Also, while I doubt it will be a huge deal, check to see what type of commitment you'd be tied to (along with how data charges would play out).
