A 4G router is the right choice if you want to create a fast internet connection on a temporary location, such as a construction site or pop-up store, or in a place where wired internet isn't great. With an LTE router, you can set up a wireless or wired internet connection via the mobile network. Via LTE Advanced, also called 4G+, you can get speeds up to 1000Mbps (125MB per second). All you need to do is put a suitable SIM card with a phone plan in the router.
