This page shares the introduction and high impact publication of the next generation 5G cellular network or mobile network. It also discussed about how and why the need for fiber optics to support and enhance 5G; simply because 5G is proposed to be the integration of human technologies. One of its standards is the International Mobile Telecommunications-2020 (IMT-2020 Standard) that is expected to be completed by 2020.

Abstract: What will 5G be? What it will not be is an incremental advance on 4G. The previous four generations of cellular technology have each been a major paradigm shift that has broken backward compatibility. Indeed, 5G will need to be a paradigm shift that includes very high carrier frequencies with massive bandwidths, extreme base station and device densities, and unprecedented numbers of antennas. However, unlike the previous four generations, it will also be highly integrative: tying any new 5G air interface and spectrum together with LTE and WiFi to provide universal high-rate coverage and a seamless user experience. To support this, the core network will also have to reach unprecedented levels of flexibility and intelligence, spectrum regulation will need to be rethought and improved, and energy and cost efficiencies will become even more critical considerations. This paper discusses all of these topics, identifying key challenges for future research and preliminary 5G standardization activities, while providing a comprehensive overview of the current literature, and in particular of the papers appearing in this special issue.

Abstract: The global bandwidth shortage facing wireless carriers has motivated the exploration of the underutilized millimeter wave (mm-wave) frequency spectrum for future broadband cellular communication networks. There is, however, little knowledge about cellular mm-wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fifth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices.

Abstract: 5G communications require a multi Gb/s data transmission in its small cells. For this purpose millimeter wave (mm-wave) RF signals are the best solutions to be utilized for high speed data transmission. Generation of these high frequency RF signals is challenging in electrical domain therefore photonic generation of these signals is more studied. In this work, a photonic based simple and robust method for generating millimeter waves applicable in 5G access fronthaul is presented. Besides generating of the mm-wave signal in the 60 GHz frequency band the radio over fiber (RoF) system for transmission of orthogonal frequency division multiplexing (OFDM) with 5 GHz bandwidth is presented. For the purpose of wireless transmission for 5G application the required antenna is designed and developed. The total system performance in one small cell was studied and the error vector magnitude (EVM) of the system was evaluated.

Abstract: A hybrid metasurface (HMS) is proposed to form a low-profile wideband antenna array. The antenna element is an array of 4 × 4 square metal patches, and fed by a 50-Ω microstrip line through an H-shaped coupling slot on the ground plane. Only are the edge patches of HMS antenna element grounded by shorting pins for the suppression of surface waves and cross-polarization levels as well as the enhancement of the gain. With the HMS antenna element, a compact 2 × 2 array with an overall size of 1.58λ0 × 1.58λ0 × 0.068λ0 (λ0 is the free-space wavelength at 5.0 GHz) is designed, where the adjacent elements share the edge patches of the elements. The measurement shows the impedance bandwidth of 28% (4.41–5.85 GHz) for |S11|≤–10 dB is obtained, and the boresight gain is greater than 8.4 dBi across the operating band, covering both 5G sub 6 GHz and WiFi bands.

  • Summary: The paper reported a multi-user access scheme that is currently under consideration for 5G systems. The non-orthogonal multiple access (NOMA) with successive interference cancellation (SIC) scheme allows simultaneous access at the same frequency-time resource. Technical areas such as power, channel allocation, optimality, etc. were discussed. The numerical results reported that the scheme can improve the system performance in both throughput and fairness over orthogonal multiple access and previous NOMA resource allocation scheme.

  • Abstract: This paper presents a novel method of decoupling inverted-F antennas (IFAs) with high-order modes of a ground plane in 5G mobile multiple-input multiple-output (MIMO) platform. The proposed method is illustrated in a dual-antenna 5G mobile platform operating at 3.5 GHz. An IFA excites a high-order mode of the field distribution in the ground plane at 3.5 GHz. The electric field of the excited high-order mode forms several stable null-amplitude field points located on the edge of the ground plane. The other IFA is then placed in one of the stable null points. By doing this, the two IFAs are decoupled with high isolation. The simulated results show that isolation improvements of 20-40 dB can be achieved when the positions and orientations of the two IFAs are optimized. The measured results confirm that the fabricated antennas have peak isolations of 45-56 dB. Finally, the proposed method is applied to design a three-IFA-based MIMO platform which verifies that the suggested concept can effectively simplify the decoupling mechanism and works well in a multiantenna-based mobile MIMO terminal.

Fiber Optics in 5G Wireless Systems

5G wireless needs fiber, and lots of it

"It’s important to lay fiber now to small and macro cells, wherever and whenever possible, if these cell sites are to be upgraded to 5G in the coming years, as copper and air-based MBH options simply cannot scale to the immense amount of backhaul traffic that’ll be generated by a 5G RAN."

5G Is Coming, and It’s Fortified With Fiber

"5G will happen in the airy realm of radio waves. To get there, big telecoms have to harness underused parts of the spectrum. But there's another crucial part underlying this system: lowly cable. Huge numbers of new transmitters will be needed to relay all that data to your phone, and many of those transmitters will still connect to the internet through fiber-optic cable—glass as thin as strands of hair carrying pulses of light. To make it all work, companies, including OFS Optics, a fiber-optics and cable company, are now being commissioned to produce millions of miles of new cable holding twice as many fiber pairs—two strands, one for the uplink and one for the downlink—as the old stuff."

The role of fiber in 5G networks

"This significantly narrows down the available options of millimeter wave network topologies, particularly over distances beyond tens of meters. However, this can be seen as a win-win for landline carriers and telecommunications companies as the costly last mile fiber-to-the-home is replaced with more agile fixed wireless access solutions while the 5G traffic offload for small cell networks will rely upon deep fiber installations to carry signals kilometers away. This way, small cell deployments can be in locations that are hard to reach by dedicated fiber or other copper wired alternatives, while fiber can run distances that small cell signals are not able to reach.
