The most common wireless technologies use radio. There are different technologies in the market like Wi-Fi, GPS, Zigbee, Bluetooth and various other modems which use radio signals for data communication. As the size and cost of these modules decrease, they become an attractive and feasible option to be used in hobbyist projects.
