Which wireless technology is popular for home automation applications due to low-power and data rate requirements?

• A. Wi-Fi
• B. ZigBee
• C. Bluetooth
• D. NFC

Answer: (B)

ZigBee is a wireless technology that is particularly well-suited for home automation applications because it is designed for low-power consumption and can operate effectively at low data rates. This makes it ideal for devices that do not require constant high throughput, such as sensors, light switches, and other smart home devices that only need to send small amounts of data intermittently. ZigBee operates in a mesh network configuration, which allows multiple devices to communicate with one another and extend the range of the network, a crucial feature for home automation where devices may be spread out over a large area. Its ability to support a large number of devices while maintaining low power usage ensures that batteries in devices can last longer, making it more convenient for homeowners. In contrast, other technologies like Wi-Fi and Bluetooth, while capable of connecting devices, tend to consume more power and provide higher data rates than necessary for typical home automation tasks. NFC is typically used for very short-range communication and is not ideal for applications needing longer-range connectivity. Thus, ZigBee stands out in the context of low-power home automation applications.
