We propose that a unified mm-wave system for combined communication and robust sensing will turbocharge the capabilities of application domains from in-home digital health to new possibilities for building analytics.

Liability of Internet Service Providers - A Review Study from the European Perspective

Internet has revolutionized peoples lives by offering a medium to share and receive abundant information. However, this resource hub has become a harbour for the infringement of IP material. Although the sole responsibility lies on the internet user; some degree of liability shouldered on the internet service providers cannot be ...

Latency control in Deterministic and Dynamic Networks

We present Deterministic Dynamic Network as a solution for 5G Edge Cloud and show how we control latency to ensure end-to-end deterministic performance of only tens of microseconds latency and tens of nanoseconds jitter per-application

Requet: Real-Time QoE Detection for Encrypted YouTube Traffic

As video traffic dominates the Internet, it is important for operators to detect video Quality of Experience (QoE) in order to ensure adequate support for video traffic. With wide deployment of end-to-end encryption, traditional deep packet inspection based traffic monitoring approaches are becoming ineffective. This poses a challenge for network ...

Analysis of Approval Voting in Poisson games

We analyze Approval Voting in Poisson games endowing voters with private values over three candidates. We first show that any stable equilibrium is discriminatory: one candidate is commonly regarded as out of contention. We fully characterize stable equilibria and divide them into two classes. In direct equilibria, best responses depend ...

A 5G mmWave Fiber-Wireless IFoF Analog Mobile Fronthaul Link with up to 24-Gb/s Multiband Wireless Capacity

We experimentally demonstrate a multiband intermediate frequency-over-fiber/mmWave (IFoF/mmWave) fiber/wireless mobile fronthaul link for gigabit capacity over the unlicensed V-band (57-64 GHz). Digital synthesis of the multiband radio waveforms is performed at the baseband unit using digital subcarrier multiplexing technique, whereas digital predistortion is exploited to cope with the analog IFoF ...

Strategies for Network Slicing Negotiation in a Dynamic Resource Market

One of the disruptive innovations introduced by 5G networks is the opportunity for a new group of stakeholders to be actively involved in the management of network slices with the role of textit{tenants}. This allows to go beyond the user-centric QoS paradigm of 4G, and to include tools for handling ...

Frequency Characteristics of Geometry-based Clusters in Indoor Hall Environment at SHF Bands

This paper presents the analysis of geometry-based cluster frequency dependency at super high frequency (SHF) bands, which are 3, 10 and 28 GHz. Firstly, multipath components (MPCs) were extracted from the measured data by using space alternating generalized expectation maximization (SAGE) algorithm. Then, geometry-based clusters were estimated by using the ...
