“…However, it is not cost-effective, since the ONU has to be associated with a wireless modem to transfer the baseband signal to its final MIMO wireless format before the wireless transmission. Therefore, it is more appealing and less expensive to deploy RoF for the transmission of MIMO wireless signals over fibre [40][41][42][43][44][45]. Moreover, analogue signal transmission leads to simpler RAUs and the analogue signals generally obtain less bandwidth than their baseband equivalents [43].…”

Next-generation access/mobile networks have set high standards in terms of providing wireless services at high data rates in order to keep up with the vast demands for other mobility and multiple services. Wireless-optical broadband access network (WOBAN) technology, also known as fibre-wireless (FiWi), has uncovered incredible opportunities for the future of next-generation networks because it gets the best of both domains: huge bandwidth provided by the optical fibre and high ubiquity of the wireless domain. The objective of FiWi networks is to integrate the high data rate and long reach provided by optical networks and the ubiquity and mobility of wireless networks, with the target to decrease their expense and complexity. Multiple-input–multiple-output (MIMO) is an inevitable technique for most of the new mobile/wireless networks that are driven by the huge data rates required by today’s users. Consequently, to construct any FiWi system for next-generation (NG) access/broadband networks, an MIMO technique has to be considered. This article presents a comprehensive, contemporary review of the latest subsystems, architectures and integrated technologies of MIMO wireless signals backhauling using optical fibre or fibre access networks, such as passive optical networks (PONs). An overview for FiWi, PONs and MIMO wireless systems is provided. In addition, advanced techniques of accommodating the MIMO wireless signals over optical fibre are explained and compared. Different types of wireless MIMO signals over fibre, such as 5G, WiFi and related transport technologies, are reviewed. Moreover, future research trends are also discussed.

“…To determine the normalised value of each RAT, it is needed to identify the main factors of the secure RATs. Based on the literature, three major parameters for a secure communication network are encryption (ENP), complexity (COMC), and response time (RST) (security in networks) [22][23][24][25][26][27] ( Tables 5 and 6).…”

Different node types in smart grid (SG) system have different communication necessities. Different type of information such as power grid status and demand requests and responses are established between control station (CS) and different SG node types. Assigning the certain percentage of the nodes traffic to the radio access technologies (RATs) with respect to their cost functions (CFs) value can help to achieve this goal by defining the highest fitness degree between SG node type communication requirements and RATs communication characteristics to have an efficient load balance. In this study, the key performance indicators (KPIs) for CFs are the SG node communication requirements which are defined as data rate, delay, reliability, and security. The value of the work can be seen in node assigning method based on the CFs as a function of different RAT communication characteristics and node type communication requirements. The highest fitness degree between node communication needs and RAT characteristics are achieved in an efficient way which causes to make an efficient heterogeneous network. The work impact of using a certain RAT which has the best efficiency in sense of communication aspects by using a well-defined CF is the innovation of this study as well.

A system of radio over free space optic (RoFSO) system using the multi‐optical carriers has been generated by the microring resonators integrating an add/drop filter. These obtained carriers have shown sufficiently stable for propagating in free space channels while experiencing very low dispersion. Moreover, this technique is appropriated for higher capacity that can be serviced in a system of wavelength‐division multiplexing (WDM) RoFSO, where there are 16 carriers created, where each carrier has 12.5 GHz free spectral range (FSR) and 220 MHz full‐width at half‐maximum (FWHM) and 8 orthogonal frequency division multiplex (OFDM) signals, then they separately modulated with 8 out of these 16 carriers. After the modulation, by utilizing an free space optic (FSO) antenna, all carriers have the optical multiplexing and transmission to a FSO channel. On the receiver side, the demultiplexing is performed and finally the performance of the system subsequently is analyzed by calculation of the constellation diagram and error vector magnitude (EVM).
