If you’re looking to demonstrate or setup a Hotspot in an area that doesn’t have a land-based ISP connection, we’d recommend using a router equipped with a USB port for a tethered 3G/4G or LTE connection. Keep in mind that 3G/4G cellular connections may not be able to handle alot of guest traffic, but with LTE you should have very good connectivity for up to 20-30 simultaneous connections.
