“…Wireless communications namely Zigbee, Wi-Fi, Bluetooth and 433 MHz, have been widely used in many applications recently. the following Table 1 gives a comparison between these wireless technologies in terms of band operated, energy consumption, range, debit and battery life [19]: However, the 433 MHz bit rate is only 9.6 kbps, making it ideal for applications in which only a small amount of data needs to be transmitted. Therefore, it is generally used for modern control systems.…”
