“…The scheduling is implemented similarly to that in Wireless HD, thus bringing along the same interference and management issues-the number of possible networks that may coexist in space and time is four. Another solution is ECMA 387 [79], which provides mobility support by dynamically resolving the cross-cloud collisions with a novel approach: soft channel switch and coordination. Basically, whenever a collision is detected, the communication channel is switched, hence reducing the subsequent collision probability.…”

Presently, smart and connected wearable systems, such as on-body sensors and head-mounted displays, as well as other small form factor but powerful personal computers are rapidly pervading all areas of our life. Motivated by the opportunities that next-generation wearable intelligence is expected to provide, the goal of this work is to build a comprehensive understanding around some of the user-centric security and trust aspects of the emerging wearable and close-to-body wireless systems operating in mass events and under heterogeneous conditions. The paper thus intends to bring the attention of the research community to this emerging paradigm and discuss the pressing security and connectivity challenges within a popular consumer context. Our selected target scenario is that of a sports match, where wearable-equipped users may receive their preferred data over various radio access protocols. We also propose an authentication framework that allows for delivery of the desired content securely within the considered ecosystem.

“…16 [24,25] and ECMA-387 [26] standards. Further, OFDM-based systems are being studied and proposed as one of the technologies to be implemented at the physical layer of 5G systems [12,17,44,46,58]. For example, OFDMbased systems combined with MIMO techniques are being suggested as the key technologies to be used at the physical layer of 5G cellular networks.…”

“…Several initiatives and proposal are ongoing to expand the current cellular bandwidth within the microwave frequency range [11], which is not enough to achieve the capacities needed by 5G systems and the devices connected to the Internet of Things (IoT). There is a vast amount of spectrum available at the mm-wave frequency bands, ranging from 3 to 300 GHz [11,17,44,46,58]; therefore, mm-wave frequency bands are being proposed to be used in 5G cellular networks.…”

Wireless technologies are an essential communication means that transform a branched localized fixed meshwork into a ubiquitous disconnected network. A clear trend shows that cells are becoming smaller, homogeneously distributed, operating at higher carrier frequencies, and more energy conscious. This points toward wireless picocell systems that implement millimeter-wave (mm-wave) modulation. In this work various techniques are proposed, which are oriented to specific traits of the 60-GHz mm-wave band. Two techniques oriented to solve physical and data-link layer issues are proposed. Single carrier frequency division multiple access (SC-FDMA) is proposed as the technology to be implemented at the physical layer, and a variable slot time multiplexing access technique, called variable slot time-time division multiple access (VST-TDMA), with a conscious energy-conservation protocol, is proposed for the data-link (MAC) layer. SC-FDMA with pulse shaping is implemented to minimize the peak-to-average power ratio of the system, which reduces energy consumption. The multiplexing access technique takes advantage of the reduced cell size by multiplexing data in the time domain, this allows the reduced number of users to utilize the entire available bandwidth. Incorporated into the access protocol is the option of energy pacing or even self-sustainability if an energy harvesting device is present. Self-sustainability can be achieved at the cost off throughput, some techniques are discussed to relieve this trade-off condition. Also, a thorough discussion is included on battery energy depletion, even with an energy harvesting device present, to further increase the through- put performance. Since using SC-FDMA reduces the energy consumption, it enables VST-TDMA to operate at higher speeds under self-sustainability mode. Overall the proposed set of solutions showed independently significant improvements to the system. It is also discussed how these techniques coalesce conveniently by working in unison, improving the energy efficiency and throughput capabilities of 60-GHz systems.Keywords 60 GHz · Energy self-sustainability · Millimeter-wave · Peak-to-average power ratio (PAPR) · Single carrier frequency division multiple access (SC-FDMA) · Variable slot time-time division multiple access (VST-TDMA)

The paper presents the characterization of a 300-GHz transmission system for modern digital communications. The quality of the modulated signal at the output of the system (error vector magnitude, EVM) is measured using a vector signal analyzer. A method using a digital real-time oscilloscope and consecutive mathematical processing in a computer is shown for analysis of signals with bandwidths exceeding that of state-of-the-art vector signal analyzers. The uncertainty of EVM measured using the real-time oscilloscope is open to analysis. Behaviour of the 300-GHz transmission system is studied with respect to various modulation schemes and different signal symbol rates.
