Which wireless technology would you choose for a high-data-rate home network to connect sensors to the Internet?

• A. LoRa
• B. Bluetooth
• C. WiFi
• D. 6LowPAN

Answer: (C)

For a high-data-rate home network that connects sensors to the Internet, you want a technology that can move a lot of data quickly and plug directly into your existing home Internet setup. WiFi fits this role because it delivers the highest data throughput among common home wireless options and works seamlessly with a home router and Internet gateway. It supports streaming data, firmware updates, and multiple devices with reliable indoor coverage, all over IP.

LoRa is designed for long-range, low-power links with very small amounts of data, so it sacrifices speed and isn’t suitable for high-rate Internet connectivity in a typical home. Bluetooth serves many close-range devices well but is limited in range and throughput for a whole-home sensor network. 6LoWPAN targets low-power, low-data-rate mesh networks over 802.15.4 and usually requires a gateway to reach the Internet, making it less appropriate for high-throughput needs.
