Low-Rate Wireless Personal Area Networks (LR-WPANs) are designed for short-range communication between devices, typically within a range of 10 to 100 meters. They are ideal for applications that require low power consumption and low data rates, such as smart home devices, wearable technology, and sensor networks. These networks use protocols like IEEE 802.15.4 to facilitate communication, allowing multiple devices to connect and share data efficiently. LR-WPANs are commonly used in environments where battery life is crucial, enabling devices to operate for extended periods without frequent recharging.
