IoT BLE Security Vulnerability

Results of a study undertaken by an SRA supported by School RKE funds.

“Things” as referred to in The Internet of “Things”, are everyday objects that have been adapted to be hosts for low energy sensors. These sensors provide the data thus enabling  these “Things” (Devices) to communicate with a network of some kind, in order to either share data or be managed, using a range of Bluetooth and Wireless technologies.

Low energy sensors can be embedded into many devices such as light switches, door locks, power sockets and actuators, which in turn are used to control or monitor more complex things such as central heating systems and home security systems.

5G Cellular Networks with Prof. Ekram Hossain

This week we were delighted to welcome Professor Ekram Hossain from the University of Manitoba, Winnipeg, Canada. Professor Hossain is a well-known IEEE fellow, author and editor in ‘Communication Networks’ publications, and is the main lead for the ‘Wireless Communication, Networks and Services (WiCoNS)’ research group at Manitoba.

ekram-hossain-5g-networks-headerProfessor Hossain introduced us to a research presentation titled ‘5G Cellular Key Enabling Technologies and Research Challenges’. The presentation included and discussed current 3G and 4G technologies, licensed and un-licensed spectrum bands, multiple and co-existing architectures, the latitude of networks for users and providers, as well as the fabrications needed to support a clear rise in user density on mobile networks. Examples of such support and architectural enhancements are smaller base stations known as femtocells, picocells, and microcells. These stand in contrast to current macrocells which are commonly known as cell towers. Continue reading
