The Bluetooth wireless communication technology which is widely used for short-range communications. It operates on 2.4GHz ISM band. In addition, Bluetooth and IEEE 802.11(Wi-Fi) devices are possible and likely to occur on the specific channel in the same location. Bluetooth devices adopt frequency hopping scheme to prevent the likelihood of mutual interferences. Although the frequency hopping can...
Bluetooth and IEEE 802.11 (Wi-Fi) are two of the most popular communication standards which define a physical and a MAC layers for wireless transmissions and operate on 2.4 GHz ISM band. To avoid the rich interference existed in ISM band, Bluetooth adopts a time-slotted frequency-hopping spread-spectrum scheme, preventing from the interference for a long time on specific channel. However, the coexistence...
This paper describes a design of a multi-channel telemetry unit for monitoring distribution switching station based on TMS320F28016 DSP. It details the composition of the hardware block diagram and the design of software. It is capable of measuring multi-channel three-phase voltage and current. In the software, it adopts Fast Fourier Transform to compute multi-channel three-phase voltage, current,...
