A low-cost BLE based sensor platform for efficient Received Signal Strength monitoring

In order to support optimized Received Signal Strength monitoring, a low-cost sensor platform based on Blue-tooth Low Energy is introduced. Using this platform RSS measurements of individual radio channels can be performed within a highly configurable mesh network with sampling rates of up to 5 kHz and an accuracy of 0.2 dB. Measured RSS can be either shared between all devices in the network in real-time or they may be stored inside each device during the time of measurement and get distributed afterwards. We analyse and describe the characteristics of the suggested platform in detail and present, as an example, a device-free indoor localization application.
