“…These include systems such as: Wireless Hart, 6LoWPAN, RFID (Radio Frequency Identification), RF4CE, SERCOS, BLE (Bluetooth Low Energy), NRF24L01, NFC (Near Field Communication) and many others. ZigBee, however, appears to be the most mature of all others in terms of suitability for telemetric applications, due to its: energy savings operation modes, relatively low throughput, high robustness to interference/multipath ([ 15 , 16 ]) and effective built-in routing and multiple access mechanisms.…”

The importance of constructing wide-area sensor networks for holistic environmental state evaluation has been demonstrated. A general structure of such a network has been presented with distinction of three segments: local (based on ZigBee, Ethernet and ModBus techniques), core (base on cellular technologies) and the storage/application. The implementation of these techniques requires knowledge of their technical limitations and electromagnetic compatibility issues. The former refer to ZigBee performance degradation in multi-hop transmission, whereas the latter are associated with the common electromagnetic spectrum sharing with other existing technologies or with undesired radiated emissions generated by the radio modules of the sensor network. In many cases, it is also necessary to provide a measurement station with autonomous energy source, such as solar. As stems from measurements of the energetic efficiency of these sources, one should apply them with care and perform detailed power budget since their real performance may turn out to be far from expected. This, in turn, may negatively affect—in particular—the operation of chemical sensors implemented in the network as they often require additional heating.

“…It has been applied in many home and industrial applications, including lighting control, remote reading of electric meters, wireless smoke detecting, medical sensing and monitoring, building automation, etc.. The biggest benefit is that ZigBee network can offer multiple channels communication ability [9]. As described in [13], the 2.4 GHz physical layer of ZigBee supports 16 channels between 2.4 and 2.4835 GHz with ample channel spacing 5 MHz aimed at easing transmit and receive filter requirements, which is summarized in Table 1.…”

Abstract-We present a robust multiple-channel vector-matching localization approach (MCVM) based on signal strength difference (SSD) fingerprinting of ZigBee Network. Compared with some existing algorithms, our presented approach has threefold advantages: firstly, far fewer numbers of received signal strength (RSS) measurements and reference nodes are needed; secondly, it shows more robustness to the fluctuation of RSS; thirdly, it requires low time-consuming signal strength collection surveys in the location space. We demonstrate the performances of our algorithm experimentally using different numbers of channels, reference nodes and training points. The Cramér-Rao Low Bound (CRLB) of SSD is derived in order to compare the performance of the different localization methods addressed. The experimental results show the efficacy of our proposed approach.

“…Beside these traditional EMC applications, these electrically large cavities are also used for antenna testing [2,3], to replicate multipath propagation in testing wireless devices [4][5][6][7][8], and also for the material scattering cross section determination [9]. The RC random field properties make them appealing also to study human exposure to electromagnetic field [10,11].…”

Abstract-This paper evaluates the mode-stirring efficiency in terms of uncorrelated positions of a mechanical stirrer operating inside a reverberation chamber (RC). The actual RC is simulated and viewed as a multivariate random process: the chamber field is sampled in a lattice of spatial points distributed uniformly over a volume of arbitrary dimensions. By adopting such a grid, the stirrer efficiency is then computed through the correlation matrix, accounting for the residual correlation between stirrer positions. The second-order statistics are calculated averaging over the sampling volume. Results are presented for two stirrers that move in both synchronous and interleaved mode. A comparison with the traditional circular correlation (CC) method, for the determination of the uncorrelated positions, is done showing how CC overestimates stirrer efficiency.
