In an IoT smart home system, sensors require high data rate and a central Internet connection. Which option should be used to connect sensors to each other and to the Internet hub?

In a smart home where sensors need high data throughput and a direct path to the Internet, WiFi fits best because it provides high data rates and seamless IP-based connectivity to the home router, which also serves as the Internet gateway. This makes it straightforward for sensors to communicate with each other on the local network and to send data to cloud services or remote apps through the Internet. The other options are more suited to different trade-offs. Bluetooth focuses on short-range, low-power links and is less scalable for many sensors spread around a home. LoRa is designed for long-range, low-power, low-data-rate communication, suitable for sparse, infrequent transmissions rather than streaming sensor data. 6LoWPAN enables IPv6 over low-power wireless networks (often using 802.15.4), but it targets low throughput and high efficiency in battery-powered devices, not the higher data rate needs typical of a robust smart-home hub connection.
