Spyridon-Nektarios Daskalakis presents...

PhD student Spyridon-Nektarios Daskalakis has produced a video entitled: 'Wireless Communication with Ambient FM Backscatter Signals - Indoor Demonstration Tag & Reader' as part of his presenattion for the IMS2017 Conference.

Spyridion-Nektarios Daskalakis's Video from @isss_hw on Vimeo.

Abstract: Nowadays, the explosive growth of Internet-of-Things-related applications has necessitated the design of low-cost and low- /zero-power wireless sensors. Although backscatter radio communication is a mature technology used in RFID applications, ambient backscattering is a novel approach taking advantage of ambient signals to simplify wireless system topologies to just a sensor node and a receiver circuit eliminating the need for a dedicated carrier source. This work introduces a novel wireless tag that utilizes broadcast frequency modulated (FM) signals for backscatter communication. The proposed proof-of-concept tag comprises of an ultra-low-power microcontroller (MCU) and a radio frequency (RF) front-end for wireless communication. The MCU accumulates data from multiple sensors through an analog-to- digital converter, while it transmits the information back to the receiver through the front-end by means of backscattering. The front-end uses On-Off keying (OOK) modulation and FM0 encoding on ambient FM station signals. The receiver consists of a commercial low-cost software defined radio which downconverts the received signal to baseband and decodes it using a suitable signal processing algorithm. The prototype tag was tested in a real-time indoor laboratory deployment. Operation over a 5 m tag-reader distance was demonstrated by backscattering information at 2 Kbps featuring an energy per packet of 36,9 uJ.

Undergraduates in Electrical Engineering visit Leonardo's

Undergraduates in Electrical Engineering visited Leonardo’s facilities at Crewe Toll in Edinburgh on both 8th and 22nd March 2017 , for a private session which aimed to align their employability skills with the company’s recruitment campaign. As well as learning first-hand information about summer/MEng placements, industrial internships and graduate programmes, students in Electrical Engineering enjoyed a private tour around this modern engineering company, learning where and how Leonardo designs, manufactures and tests their radar and laser products.Leonardo

“It is very important that our students understand what a career in high frequency engineering involves, the required skills and the prospects for career development. Leonardo is a major corporation in Aerospace, Defence and Security, which is just a stone’s throw away from Heriot-Watt and by working together we can support the development of our future engineers.” Dr Carolina Mateo-Segura, Assistant Professor, Heriot- Watt University

The event took place in parallel to the learning and teaching strategies developed by the RF- and Microwave Engineering group, which aims to involve industry in designing the current curriculum and projects. It also took place in parallel to the learning and teaching strategies developed by the RF- and Microwave Engineering group, which aims to involve industry in designing the current curriculum and projects. Neil Raphael, lead Engineer at Leonardo, hopes to make it an annual event in an effort to accelerate their graduate recruitment process through a plan of action and re-setablishing the collaboration between Leonardo and Heriot-Watt University.

Equate Scotland at Heriot-Watt University

Equate Scotland, Women in Science, Engineering and Technology has been in Heriot-Watt presenting a series of thought-provoking activities and discussions, exploring lawful ways of increasing women’s participation and progression in STEM. The workshop highlighted unconscious bias in a STEM context and the actions required to encourage talented women to join and stay in STEM. Women and girls have the skills and aptitudes needed to thrive in science, technology and engineering, yet remain grossly underrepresented. STEM academia needs these skills, along with the new ideas and problem solving that flourish in diverse workforces. Dr. Carolina Mateo-Segura who participated in this programme said “You cannot be what you cannot see; girls need to see the roles of women in engineering careers, the picture that we are projecting does not justify the range of disciplines that engineering embrace. We need to get out there and inspire girls by communicating our own vision with the hope to make a better informed decision and bring diversity to this field.”

September 2016

Undergraduate outreach event to encourage engineering careers: On Thursday 29 September Dr. Symon Podilchak, the DORADA fellow seconded from Heriot-Watt University to Space Engineering, delivered a motivational talk to undergraduate students at La Sapienza Univeristy in Latina, a suburb of Rome. The focus of the talk was applied electromagnetic engineering for microwave and millimetre-wave frequency devices with applications to wireless systems, radar, and satellite communications. The basic motivation of the talk was to show 2nd and 3rd year students, who are just being introduced to the physics and mathematics of electromagnetic principles, the practical and applied side of electromagnetic engineering. Basically such that students can appreciate that the basic concepts that they are learning now, can be actually very useful in a multitude of common engineering situations.

Symon DORADADORADA fellow from Scotland reaches out to La Sapienza: On Wednesday 21 September Dr. Symon Podilchak, the DORADA fellow seconded from Heriot-Watt Unviersity to Space Engineering, delivered a research seminar in La Sapienza Univeristy in Rome.

NASA for webNASA for web.2

June 2016

Researchers from Heriot-Watt together with a team from NASA have installed a satellite terminal within the university collecting transmissions from a geostationary satellite to assess the atmospheric absorption of the higher frequency waves. If Q-band communications is to be viable then reliable gateway feeds to transfer data need to be established and this is what the Heriot-Watt installation will help to record. This is the start of an experiment to discover just how reliable the Q-band might be and whether it has a commercially viable future for telecommunications companies to use. Researchers hope that the experiment will result in higher frequencies (40 GHz, also known as Q-band) being used for future higher capacity satellite communication systems. This in turn may eventually release high bandwidth satellite links and improve broadband communication on planes, trains and other fast-moving platforms.
