“…The major drawbacks of a mm-wave RoF system are that, as the RF frequency increases, so does the requirement of sophisticated DL optical transmitters at the CS (NE2) [43][44][45][46][47][48], efficient topologies for the ODN (NE7) [49][50][51][52][53], and low-cost and "green" UL transmitter configurations at the BS (NE14) [54][55][56][57]. Thus, the proposed framework considers these NEs as key network elements (KNEs).…”

This paper presents the research work involved in the development of a knowledge-based framework for the design of millimeter-wave 60 GHz radio over fiber (RoF) land networks. It combines object-oriented, rule-based, technical information, and procedural functions to support engineers in the conceptual and preliminary design of a network. The overall framework is organized in two main modules: the first module is a tutorial of the terminology and basic principles in the design of RoF networks. The second module is a design assistant system that requests input data from the user about the functional network requirements and its prioritized figures of merit. The proposed design assistant is capable of providing support on the major activities of the 60 GHz RoF land network design such as downlink and uplink channel assignment and network clustering, wavelength allocation, optical link design, and network integration. The assistant is user interactive through the implementation of a graphical user interface. To illustrate the validation of such framework, we present a case of study of a network design with specific requirements.

A scheme for the generation of mm‐wave signals at different frequencies with improved performance is proposed and demonstrated by employing a uniform fiber Bragg grating based acousto‐optic tunable filter (UFBG‐AOTF). The different frequencies carry different information at a required data rate according to their application. This method reduces the complexity of the system by alleviating the cascaded Mach‐Zehnder modulators (MZM) and a good transmission performance can be achieved by the FBG. In the previous system, the distance of transmission is reduced to 15 km due to bit walk‐off effect and it also reduces the BER values at larger distances. In the proposed system, the bit walk‐off effect is discussed and compensated to increase the transmission distance up to 60 km. The simulation results along with clear eye‐diagrams show that the BER values are improved at larger distances than the previous system which proves the performance improvement of the proposed system.

“…For this reason mm-wave technology is becoming the new alternative for Wireless Personal Area Networks (WPAN) [35,54,59]. Due to their limited size these access points are sometimes referred to as picocells [33,36,49] or (less frequently) microcells [22]. mm-Wave systems have already proven to transmit at 2.5 Gbps [14], using simple techniques.…”

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)
