'Wireless' Humans As New Mobile Networks


Members of the public could form the backbone of powerful new mobile networks by carrying wearable sensors.

According to researchers from Queen’s University Belfast in Northern Ireland, the novel sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations.

The engineers from Queen’s Institute of Electronics, Communications and Information Technology (ECIT), are working on a new project based on the rapidly developing science of body centric communications.

The researchers at ECIT are investigating how small sensors carried by members of the public, in items such as next-generation smartphones, could communicate with each other to create potentially vast body-to-body networks (BBNs). The new sensors would interact to transmit data, providing ‘anytime, anywhere’ mobile network connectivity.

Simon Cotton, an ECIT wireless communications research fellow, said: “In the past few years, a significant amount of research has been undertaken into antennas and systems designed to share information across the surface of the human body. Until now, however, little work has been done to address the next major challenge which is one of the last frontiers in wireless communication — how that information can be transferred efficiently to an off-body location.

 “The availability of body-to-body networks could bring great social benefits, including significant healthcare improvements through the use of body-worn sensors for the widespread, routine monitoring and treatment of illness away from medical centers.

“If the idea takes off, BBNs could also lead to a reduction in the number of base stations needed to service mobile phone users, particularly in areas of high population density. This could help to alleviate public perceptions of adverse health associated with current networks and be more environmentally friendly due to the much lower power levels required for operation.”

Cotton has been awarded a prestigious joint five-year Research Fellowship by the Royal Academy of Engineering and the Engineering and Physical Research Council (EPSRC) to examine how the new technology can be harnessed to become part of everyday life.

He added: “Our work at Queen’s involves collaborating with national and international academic, industrial and institutional experts to develop a range of models for wireless channels required for bodycentric communications. These will provide a basis for the development of the antennas, wireless devices, and networking standards required to make BBNs a reality.

“Success in this field will not only bring major social benefits it could also bring significant commercial rewards for those involved. Even though the market for wearable wireless sensors is still in its infancy, it is expected to grow to more than 400 million devices annually by 2014.”

Along with ECIT Professor William Scanlon (who holds the Queen’s Chair in Wireless Communications), Cotton recently received the H.A. Wheeler Applications Prize Paper Award from IEEE for a study on a wireless body centric radio system that could be used by the emergency services.
