Which technology enables high data rate wireless communication in home networks?

• A. LoRa
• B. Bluetooth
• C. Sigfox
• D. WiFi

Answer: (D)

High data rate wireless communication in a home network is best provided by a technology built for fast local networking and many connected devices. WiFi is designed to deliver high throughput, supporting activities like streaming, gaming, and internet access across multiple devices in a home. The other options prioritize different goals: LoRa and Sigfox are LPWAN technologies optimized for long-range, low-power communication with very low data rates—great for sensors but not for bandwidth-heavy home use. Bluetooth covers short-range connections with modest data rates and is ideal for peripherals, not for handling the large data transfers typical of a home network. So, for high-speed wireless networking inside a home, WiFi is the appropriate choice.
