Enhanced Communication Distance

The Bluetooth is an industry standard for short-range wireless communication for personal use. At the time when it was first developed, the distance was approximately 10m. However, using the Bluetooth connection to a variety of devices based on the communication range is classified into three kinds of class. The Class 1 is to have the communication distance of up to 100m , Class 2 is 30m, Class 3 supports the communication distance up to 10m. The WCS-232 is a Bluetooth Class 1 device.

Bluetooth v2.0 + EDR

EDR stands for Enhanced Data Rate. THE EDR allows fast data transfer technology in Bluetooth communication. Bluetooth was initially developed to support the communication speed up to 1Mbps, but when EDR function is used, the maximum communication speed is increased up to 3Mbps.
