WiFi, Bluetooth or RF - Which Should You Choose?
Choosing between WiFi, Bluetooth, and RF depends mainly on the required range and how the serial device needs to communicate.
Serial WiFi adapters are ideal when you want to connect serial equipment to an existing WiFi network and access it from computers or other network devices. Multiple adapters can easily be connected to the same PC. Max range is up to 300 feet, however a typical WiFi extender can extend this range.
Serial Bluetooth adapters provide a simple and convenient way to connect a serial device directly to a PC or make a direct cable replacenet by linking two adapters, making them well suited for short-to-medium-range point-to-point connections. Point to multipoint connections are also possible. Max range is up to 300 feet.
Serial RF Radios create a dedicated wireless link without requiring WiFi or Bluetooth infrastructure and are typically the better choice when longer range and reliable device-to-device communication is important. Point to multipoint is also possible. Max range is up to 30.000 feet with very good signal penetration.
In short, choose WiFi for network connectivity, Bluetooth for simple cable replacement, and RF for dedicated long-range wireless serial communication.
