“…Two channel models including C2 and C3 and four probe configurations including P2, P3, P5, and P7 were adopted to validate the performance of the above MA-based method. A performance comparison between the methods in [53,54] is made in Table 7. However, the method should be further applied into 5G channel models and future channel models possessing more complex characteristics which will greatly improve the application of MPAC-based OTA testing method.…”

With the fast development of communication techniques, over-the-air testing has developed into the main testing method for current communication systems due to its advantages including no cable connection, high measurement efficiency, and independence from environment. OTA testing has become almost the only solution for 5G system testing especially after the popularity of 5G massive multiple-input-multiple-output. In this paper, we summarize the three main methods of OTA testing including the reverberation chamber-based method, the radiation two-step method, and the multiprobe anechoic chamber- (MPAC-) based method, among which we focus on the MPAC method systematically. In the MPAC method, there are two main channel synthesis techniques that have been heavily studied, namely, prefaded signal synthesis and plane wave synthesis. We summarize the current main research based on these two techniques including probe configurations, probe selection algorithms, and probe design based on the PFS technique and the design of plane wave generators based on PWS technique. The main comparisons are made for the performance of different probe selection algorithms and the performance of different plane wave generators as well as the latest advances.

“…Use of multiple small antennas and base stations -5G involves higher frequency radio waves and they can be targeted. The biggest 5G implementation challenge with 5G antennas is its limited range irrespective of the fact that it can handle more users and data and can be beamed out over shorter distances [21]. Even though antennas and base stations used in such situations are smaller, it is likely that these would have to be installed on homes or buildings.…”

5G which stands for 5 th Generation Mobile technology, is a groundbreaking technology that the world now witnesses in mobile telecommunications and which has proven to be twenty or more times faster than the existing 4G technology. New standard releases beyond 4G are already in progress by standardization bodies, but at this time implementation and rollout of systems compliant with 5G is still under way in some parts of the world. The goals of a 5G-based telecommunications network would ideally answer the challenges that a 4G model would present once it has entered widespread use. The innovative features of 5G in many ways can be employed to support governments, established companies, new ideas, business models and services that require continuous connections between multiple parties that may include enterprises, telecom providers, mobile operators, government regulators, infrastructure providers and much more. This research highlighted the idea behind 5G technologies, its interconnections with smart objects of Internet of things (IoT) as well as offerings it has gained from others like Blockchain technology. The design for system model of network architecture for 5G mobile systems is described including creating IP tunnels over IP interfaces obtained by connection to the terminal via the access technologies available to the terminal (i.e., mobile user). The economic impact and the contributions of 5G technology is vigorously highlighted while some of the challenges that is faced in designing, deploying and managing the technology is also probed.
