MicroBot Alert connects to a smartphone or tablet using Bluetooth Low Energy (4.0 or BLE). The distance can vary from 30 to 230 feet or 10 to 70 meters, depending on the smartphone's antenna performance and the environment where the MicroBot Alert is located. If there are a lot of walls or networks the range can be reduced. In an open space, the range can be as far as 230 feet.
