how do hotspots work for wifi
A Wi-Fi hotspot works much the same as the Wi-Fi you find in most homes. A wireless access point communicates with computers and other Wi-Fi devices using radio signals. This Wi-Fi access point is connected to the Internet and is usually connected to a router or a server that regulates who can access the Wi-Fi.How the signals are sent and received is standardized, using the 80211 standards developed by the Institute of Electrical and Electronics Engineers (IEEE).any places offer free Wi-Fi hotspots as a public service, including airports, libraries, college campuses and other public locations. Restaurants, coffee shops and hotels may offer free Wi-Fi hotspots to attract customers.
