How to Set Up a 4G LTE Wi-Fi Network as an Alternative to Broadband

Photograph: NetgearThe idea behind 4G LTE at home is pretty simple at its core: Deliver internet access to your home in the same way that your phone gets online when it's away from Wi-Fi. If you've ever tried to connect your laptop to a hot spot running from your phone, then you know what's involved, together with all the potential pros (wireless internet access anywhere) and cons (interference and bandwidth issues).
