Creating and sharing knowledge for telecommunications

15th International Symposium on Wireless Communications Systems - ISWCS 2018


on 28-08-2018

... IT and ISCTE-IUL will be hosting the prestigious 15th International Symposium on Wireless Communication Systems (ISWCS 2018), between 28-31 August 2018. The symposium focuses on wireless communications, both on physical layer and networking aspects, and is a premier forum in the fields of signal processing for wireless communications, communication theory, channel modelling, and networking theory and practice.

This year's edition is technically co-sponsored by the IEEE Communications Society (ComSoc), the IEEE Vehicular Technology Society (VTS), and by The European Association for Signal Processing (EURASIP).

ISWCS 2018 will welcome over 200 academic and industrial researchers, scientists, engineers, and business people (from more than 50 countries). It will feature world-level keynote talks and tutorials on hot topics, and over 140 technical presentations of peer-reviewed papers. It will also encompass two independent technical workshops, and prototype hardware demonstrations. More Information..

Abstract:

Detecting ocean-floor seismic activity is crucial for our understanding of the interior structure and dynamic behaviour of the Earth. However, 70% of the planet’s surface is covered by water and seismometers coverage is limited to a handful of permanent ocean bottom stations.

In the first part of this talk I discuss our recent results [1], where we showed that existing telecommunication optical fibre cables can detect seismic events when combined with state-of-the-art frequency metrology techniques by using the fibre itself as the sensing element. We detected earthquakes over terrestrial and submarine links with length ranging from 75 to 535 km and a geographical distance from the earthquake's epicentre ranging from 25 to 18,500 km. Implementing a global seismic network for real-time detection of underwater earthquakes requires applying the proposed technique to the existing extensive submarine optical fibre network.

In the second part of the talk I will discuss briefly how we distributed entanglement between Malta and Sicily [2] over the telecommunications network using polarisation-entangled photon pairs.
