The very large bandwidth available in the 60 GHz band allows, in principle, to design highly accurate positioning systems. Integrating such systems with standard protocols (e.g., IEEE 802.11ad) is crucial for the deployment of location-based services, but it is also challenging and limits the design choices. Another key problem is that consumer-grade 60 GHz hardware only provides coarse channel state information, and has highly irregular beam shapes due to its cost-efficient design.

Enterprise Networking has a strong set of requirements in terms of resiliency, reliability and resources usage. With current approaches being based on monolithic and expensive infrastructures using dedicated overlay links, providers are moving to more economical hybrid solutions that encompass private dedicated links with public/regular Internet connections.

Among the primary challenges of the roll out 5G networks are the protocol level issues it faces. Issues such as mm-wave beamforming, initial access, MAC layer design, mm-wave localization, network architectures, are all proving to be key elements that must be addressed. Both industry and academic research is still at an early phase of this work and for it to progress work must be done on a number of fronts in terms of test and measurement and other issues. This webinar will examine the work that is being done in addressing these issues and some of the solutions that have been developed.

This integrated demo will interconnect different transport technologies carrying backhaul traffic, fronthaul traffic and both in one network, which demonstrates the 5G-Crosshaul data plane technologies developed in the project.

The seminar will provide an introduction to the Project Loon, a network of balloons designed by Google to extend Internet connectivity to people in rural and remote areas worldwide. We will review its main technical characteristics and how it has evolved in the last couple of years. It will also review the activities carried out in cooperation with Telefónica in Latam, including technical trials in Chile and Perú, and provide an assessment of the main issues the project faces to become a sustainable commercial system. Although not likely to be covered in the seminar, we will also provide some information about other alternatives to provide connectivitivy using aerial networks, like

Despite the hype about blockchains and distributed ledgers, no formal abstraction of these objects has been proposed. To face this issue, in this paper we provide a proper formulation of a distributed ledger object. In brief, we define a ledger object as a sequence of records, and we provide the operations and the properties that such an object should support. 

Collecting data generated by widespread digital transactions is an increasingly common practice. The likes of telecommunication network operators, mobile service providers, app developers and financial companies have the possibility to track the movements, preferences, activities and habits of large populations of individuals.
