“…The transmission speed of 5G is faster than that of 4G by about 10 to 100 times. Indeed, with values reaching 15 or 20 Gbit/s and with the use of the cloud, 5G has managed to directly and instantly access programs, files, and remote applications [58][59][60]. With the increasing use of the cloud, the giant internal memories of devices are no longer essential as information storage, and even software activation have become possible remotely in the cloud [61].…”

The evolution of the global wireless market is accompanied by an increased need in terms of speed and number of users, lower latency, better coverage, better spectral efficiency and quality of service, etc. To meet these needs, 5G has recently been introduced as an effective solution which targets, via the large scale deployment of symmetric antennas, a wide variety of sectors such as energy, health, media, industry, transport and especially wireless cellular networks which are among the most important pillars of modern societies. Multiple Input, Multiple Output (MIMO) systems, which have been extended to “Massive MIMO” mode and which consist of increasing the number of radiating elements involved in the transmission and reception of the radio link, are a very promising solution for improving the spectral efficiency of wireless communication systems (WCSs). Motivated by the aforementioned developments, the present paper investigates the increased capacity of MIMO systems to improve transmission in WCSs using 5G. It carefully focuses on the evaluation of the development level and technical contribution of MIMO systems and millimeter wave (mmWave) bands in 5G wireless cellular networks (WCNs) and gives important recommendations.

“…The passive optical network can support bandwidth-intensive as well as low-latency services for 5th generation mobile networks by using channel bonding and low-latency oriented DBA [22]. Next application of time and wavelength division multiplexed PON (TWDM-PON) is in front hauls streams in the centralized radio access network (C-RAN) architecture of mobile networks [23,24].…”

Sophisticated dynamic bandwidth allocation (DBA) algorithms can dramatically improve or worsen throughput and delay in whole networks. It is very important to choose the right DBA algorithm. Our work tests static assignment and three DBA algorithms, namely GigaPON Access Network DBA, Hybrid Reporting Allocation, and modified Max–Min Fair. All tests were made on our simulator of ten-gigabit passive optical network DBA specially developed for testing DBA algorithms. The tests verify delay of each optical network unit and amount of waste with bandwidth. This paper describes how the used DBA algorithms work and the processes involved in DBA algorithms.

“…High-speed and large-capacity data transmission will be required in future wireless-communication systems. The carrier frequency used in optical wireless communication is higher than that in the terahertz band, which can enable us to meet the demand beyond 5G communication systems [1,2,3,4,5]. In addition, the antenna for optical wireless communication can be downsized because of the very short wavelength in the optical bands, and silicon photonics would be suitable for manufacturing such a small antenna for mass production at low cost [6,7,8,9,10,11,12,13,14,15,16,17,18].…”
