WiFi modules allow for machine to machine (M2M) connectivity across a WiFi network. There are several types of WiFi networks, IEEE 802.11 a/b/g/n/ac. As a result, a WiFi module can be single-band or dual-band and can communicate on two networks. Bluetooth modules allow for M2M connectivity across a Bluetooth network. Common protocols used by these modules are Bluetooth and Bluetooth Low Energy (BLE). Combination WiFi and Bluetooth modules are also available.
