Until recent years, industrial control systems relied on wires to transfer the process values and control signals through an industrial plant. The use of wireless is limited to monitoring non-critical process values and using it for process control was uncommon for several reasons: complexity of usage, reliability, power consumption and a general doubt on its advantages. Wireless technology has made...
This paper presents a new transceiver for impulse radio ultra-wideband (IR-UWB) systems. This work is related to CHIST-ERA SMARTER project (Smart Multifunctional Architecture and Technology for Energy aware wireless sensoRs) which address autonomous wireless sensors nodes. The ultra low-power transceiver consists of an on-off keying (OOK) modulator/demodulator and a pulse generator. To reduce power...
Wireless sensor networks (WSNs) include a large number of distributed sensor nodes that consist of sensor, microcontroller and transceiver block. As the main source of energy sensor nodes usually use non-rechargeable batteries, so that the stored energy is a very important resource of a WSN. The main goal of this paper is estimating the battery lifetime of a sensor node in respect to the usage pattern...
The use of sensing technologies in industrial environments has opened many possibilities for monitoring and control applications, driving much research efforts in the last years. Among the challenging issues related to industrial wireless sensor networks, efficient nodes deployment is a major concern since it can directly impact the way sensors operate, which has demanded proper solutions. When sensing...
In this paper we analyze energy-efficiency vs. performance trade-off in low power wireless communications at component level and check hypothesis that the trade-off can be improved by introducing power supply voltage as design variable compared to the case when power supply voltage is fixed. We set two testing formulations and analysis based on SI4455 transceiver show that the hypothesis holds true...
This paper briefly presents a 60-GHz dual-chip wireless communication solution adhering to the IEEE 802.11ad standards. The proposed fully-integrated transceiver front-end chip (RFIC) using a sub-harmonic sliding-IF scheme to reduce the design difficulty on VCO, was implemented based on a low cost SiGe 0.18um BiCMOS process and has a compact chip area of 5mm by 3.9mm with a low power consumption of...
Multichip systems with memory stacks and various processing chips are at the heart of platform based designs such as servers and embedded systems. Full utilization of the benefits of these integrated multichip systems need a seamless, and scalable in-package interconnection framework. However, state-of-the-art inter-chip communication requires long wireline channels which increases energy consumption...
Dealing with critical health issues requires the existence of an intelligent health care system capable of monitoring the patients wherever they are, which increases the demand for a wireless health care system. One possible realization of such a system is the wireless body area network standard defined by IEEE 802.15.6. Based on IEEE 802.15.6, this paper proposes a low complexity implementation of...
Wireless Networks-on-Chip (WiNoCs) offer unprecedented advantages to replace the long-distance multi-hop communication bottlenecks of conventional NoCs by augmenting them with a single hop, long-range wireless links in many-core systems. In wireless interfaces (WIs), RF transceiver components are consuming a significant amount of total power budgets to replace the multi-hop communications. Specifically,...
300 GHz is the upper limit frequency of millimeter waves, and is also the entrance of terahertz. The use of the 300-GHz band for wireless communication is being discussed by International Telecommunication Union (ITU) and The Institute of Electrical and Electronics Engineers (IEEE) since frequencies beyond 275 GHz are unallocated. In the 300-GHz band, since atmospheric attenuation is as small as several...
The deployment of smart grid communication networks (SGCN) in urban areas has been possible due to the huge availability of wired and wireless communication technologies. However, in rural areas, those communications options are usually not available, unsuitable and/or too costly, making the deployment of a SGCN more challenging in such a case. On the other hand, the recently introduced low power...
The objective of this paper is to consider the use of digital accelerometers for Mechanomyographic applications. The digital outputs of the accelerometer require the consideration of additional interfacing hardware for any commercial data acquisition systems being considered. The Arduino open-source platform is shown to meet this requirement. This platform also provides access to set the data registers...
We identify phase noise as a bottleneck for the performance of digital self-interference cancellers that utilize a single auxiliary receiver — single-tap digital cancellers — and operate in multipath propagation environments. Our analysis demonstrates that the degradation due to phase noise is caused by a mismatch between the analog delay of the auxiliary receiver and the different delays of the multipath...
