“…The tower station of a WiMAX can be directly connected to a wired network (backbone), having a wide bandwidth, as shown in Figure 25. The fixed backhaul-connected WiMAX base station provides relatively high-speed internet connectivity (data access) to customers wirelessly (via WiMAX microwave) connected, for example in cafés, stations, offices, houses, and business spots [154]. The construction of similar neighboring towers taking the fixed backhaul connection from the internet backbone network will increase connectivity.…”

This review paper discusses the complete evolution of free-space optical (FSO) communication, also known as unguided optical communication (UOC) technologies, all the way back to ancient man’s fire to today’s machine-learning-supported UOC systems. The principles, significance, and developments that have happened over the past several decades, as well as installation methodologies, technological limitations, and today’s challenges of UOCs are presented. All the subsets of UOC: FSO communication, underwater optical wireless communication (UOWC), and visible light communication (VLC), with their technology/system developments, potential applications, and limitations are reviewed. The state-of-the-art developments/achievements in (i) FSO channel effects and their mitigation techniques; (ii) radio-over-FSO techniques; (iii) wavelength division multiplexing and sub-carrier multiplexing techniques; (iv) FSO for worldwide interoperability for microwave access applications; (v) space optical satellite communication (SOSC); (vi) UWOC; (vii) photoacoustic communication (PAC); (viii) light-fidelity; (ix) VLC; (x) vehicular VLC (V2LC); and (xi) optical camera communication are reviewed. In addition, the current developments on emerging technologies such as artificial intelligence (to improve the performance of UOC systems), energy harvesting (for the effective utilization of UOC channels), and near-future communication network scenarios (mandatory for secured broadband digital links) are covered. Finally, in brief, to achieve the full potential of UOC systems, challenges that require immediate research attention are summarized.

“…Previous studies have proposed compact UWB trapezoidal antennas with dual-band notching characteristics [ 8 , 9 , 10 , 11 ] and UWB antennas with triple notching [ 12 , 13 , 14 , 15 , 16 ] to address this issue. These techniques involve the insertion of comb slot shapes into the radiating patch to achieve notching, while the UWB characteristics are achieved through ground structure modifications in a staircase form [ 17 , 18 , 19 , 20 ]. In addition, UWB uses a variety of techniques for notching [ 21 , 22 , 23 , 24 , 25 , 26 ], and switches and stubs are embedded in the slot antenna [ 27 , 28 , 29 , 30 , 31 ].…”

This study introduces a monopole 4 × 4 Ultra-Wide-Band (UWB) Multiple-Input Multiple-Output (MIMO) antenna system with a novel structure and outstanding performance. The proposed design has triple-notched characteristics due to CSRR etching and a C-shaped curve. The notching occurs in 4.5 GHz, 5.5 GHz, and 8.8 GHz frequencies in the C-band, WLAN band, and satellite network, respectively. Complementary Split-Ring Resonators (CSRR) are etched at the feed line and ground plane, and a C-shaped curve is used to reduce interference between the ultra-wide band and narrowband. The mutual coupling of CSRR enables the MIMO architecture to achieve high isolation and polarisation diversity. With prototype dimensions of (60.4 × 60.4) mm2, the proposed antenna design is small. The simulated and measured results show good agreement, indicating the effectiveness of the UWB-MIMO antenna for wireless communication and portable systems.
