WiFi Wireless Module VS LoRa module
WiFi Wireless Module and LoRa module are two different wireless communication technologies, and they have obvious differences and contrasts in several aspects.
Communication range:
WiFi Wireless Module: WiFi modules are usually suitable for relatively short-distance communication, and generally can cover a range of tens of meters to hundreds of meters in an indoor environment. Its transmission distance is affected by physical obstacles and signal interference.
LoRa module: LoRa module adopts low-power wide area network (LPWAN) technology, has a long communication range, can cover a range of several kilometers to tens of kilometers in an outdoor environment, and has good penetration and anti-interference capabilities.
Transmission rate:
WiFi Wireless Module: WiFi modules usually provide a higher transmission rate and can support data transmission speeds up to several hundred megabits per second. This makes WiFi suitable for applications that require the transfer of large amounts of data quickly, such as video streaming and large file transfers.
LoRa module: The transmission rate of the LoRa module is low, generally in the range of several kilobits per second to hundreds of kilobits per second. It is mainly used in IoT applications with low power consumption and more emphasis on long-range transmission and long battery life.
Power consumption and battery life:
WiFi Wireless Module: WiFi modules typically require high power consumption, which can be a burden on battery-powered devices, limiting their usage time in low-power applications.
LoRa module: LoRa module uses low power consumption technology, has excellent energy efficiency, and can run on battery power for a long time, usually up to several years of battery life.
Network topology and deployment:
WiFi Wireless Module: The WiFi module is usually used to build a local area network (LAN), and the device needs to connect to an existing WiFi network or communicate through a WiFi router. This network topology requires certain infrastructure support.
LoRa module: The LoRa module can build a low-power wide-area network (LPWAN), has the ability to self-organize the network, does not require complex infrastructure support, and can achieve wide-area coverage and long-distance communication.
According to specific application requirements, select the appropriate wireless communication technology. The WiFi Wireless Module is suitable for short-distance, high-speed transmission applications, while the LoRa module is suitable for long-distance, low-power Internet of Things applications.
