A Hotspot provides connection to Wi-Fi through a cellular data connection. Many Phones and Tablets can function as a HotSpot (Wi-Fi + Cellular) when you don't have access to a Wi-Fi network.
Important: If you are using a personal or non-district provided Hotspot, check with your phone provider to know how much data you have per month or if it is unlimited before setting up the hotspot.
District provided hotspots will provide 10G of free high-speed LTE data per month. If usage exceeds 10G per month data is still unlimited at 2G.
