The term short-range wireless communication means communication at wireless PAN and wireless LAN
The term short-range wireless communication means communication at wireless PAN and wireless LAN.
Applications of WPAN include Bluetooth and Zigbee which are operated at the 2.4GHz band.
Zigbee has been used in Japan for remote control applications that demand response.
For applications that continuously transmit data (i.e. sensor information from a gaming controller or music from a mobile device to a speaker) the fast communication speed of Bluetooth is particularly effective.
Enocean is a system for transmitting data without wires and also that it requires no power supply or maintenance, and instead uses stored energy to generate the small amount of energy needed from the environment (i.e. light, temperature difference).
The frequency changes with the region. In Japan this is differentiated as specified low power wireless using the 315MHz and 928MHz frequencies. In the US 315MHz and 902MHz are used while the EU adopts 868MHz.
Wi-Fi uses the 2.4GHz and 5GHz bands and provides fast communication speeds.
If this is combined with a communication distance of about a few hundred meters, make it the preferred method for using a wireless network for connecting to the internet in the home.
