We use Class 2 Bluetooth® module with a range of up to 100 feet/30 meters. The range of 100 feet/30 meters is the best achievable range under perfect conditions. In real life situations, the device usually provides a range of 15 to 45 feet/5 to 15 meters, and we prefer to provide you with actual facts and not create unrealistic expectations so that you can act accordingly. Since we are talking about emergencies where every second counts we recommend keeping your phone within 15 feet/5 meters from the ring, where the connection works well in most situations. You should also know that the range depends not only on the transmitter and the mobile phone which is receiving data, but also depends on weather, geographic and local conditions.
