Low-power wireless communication refers to the use of wireless technologies that consume minimal energy
Low-power wireless communication refers to the use of wireless technologies that consume minimal energy during transmission and reception. This type of communication is commonly used in applications where devices have limited power sources, such as battery-powered devices or energy-harvesting systems. Low-power wireless communication enables efficient data transfer over short to moderate distances while conserving energy and extending battery life. Several wireless technologies are designed specifically for low-power applications, including:
Bluetooth Low Energy (BLE): BLE is a wireless communication standard that consumes very low power. It is commonly used in applications such as wearable devices, fitness trackers, and home automation systems. L BLE devices operate in the 2.4 GHz frequency band and offer short-range communication.
Zigbee: Zigbee is a low-power wireless technology designed for applications requiring low data rates and long battery life. It operates in the 2.4 GHz or sub-GHz frequency bands and is commonly used in smart home automation, industrial automation, and wireless sensor networks.
Z-Wave: Z-Wave is a wireless technology that focuses on low-power consumption and reliable communication in smart home applications. It operates in the sub-GHz frequency range and offers good range and penetration through walls and obstacles.
LoRaWAN: LoRaWAN (Long Range Wide Area Network) is a low-power, wide-area networking protocol that enables long-range communication while consuming minimal power. It is suitable for applications such as smart cities, agriculture, and industrial monitoring, where low data rates and long battery life are essential.
NB-IoT (Narrowband Internet of Things): NB-IoT is a low-power wide area network (LPWAN) technology that operates on licensed cellular bands. It is designed specifically for Internet of Things (IoT) applications and offers long-range communication with extended battery life.
These technologies incorporate power-saving techniques such as duty cycling, where devices alternate between active and sleep modes to conserve energy. Additionally, they employ efficient data transmission protocols and optimized hardware designs to minimize power consumption while maintaining reliable communication.
