“…It is noted that the network topology is not necessarily star type but cluster tree type is also possible where the number of fronthaul links connected to C-RAN is reduced. Moreover, wireless fronthaul between C-RAN and smallcell BSs is almost ready at mm-wave band [29] that will reduce the cost of deployment of a large number of smallcell BSs.…”

SUMMARYTriggered by the explosion of mobile traffic, 5G (5th Generation) cellular network requires evolution to increase the system rate 1000 times higher than the current systems in 10 years. Motivated by this common problem, there are several studies to integrate mm-wave access into current cellular networks as multi-band heterogeneous networks to exploit the ultra-wideband aspect of the mm-wave band. The authors of this paper have proposed comprehensive architecture of cellular networks with mmwave access, where mm-wave small cell basestations and a conventional macro basestation are connected to Centralized-RAN (C-RAN) to effectively operate the system by enabling power efficient seamless handover as well as centralized resource control including dynamic cell structuring to match the limited coverage of mm-wave access with high traffic user locations via user-plane/control-plane splitting. In this paper, to prove the effectiveness of the proposed 5G cellular networks with mm-wave access, system level simulation is conducted by introducing an expected future traffic model, a measurement based mm-wave propagation model, and a centralized cell association algorithm by exploiting the C-RAN architecture. The numerical results show the effectiveness of the proposed network to realize 1000 times higher system rate than the current network in 10 years which is not achieved by the small cells using commonly considered 3.5 GHz band. Furthermore, the paper also gives latest status of mm-wave devices and regulations to show the feasibility of using mm-wave in the 5G systems.

“…First, existing radio services are encapsulated in the terahertz signal by using a frequency upconversion technique. This scheme is equivalent to a radioon-radio configuration [9], [10], [11], [12]. The terahertz signal cannot affect the existing services because of the difference in frequencies.…”

The technology of encapsulating a microwave signal into a terahertz carrier and an optical signal is proposed and demonstrated experimentally. Broad bandwidth terahertz radio can encapsulate existing microwave services, including advanced mobile communication signals, by using photonics technology. The concept of radio-on-terahertz-over-fiber helps to realize the future design of mobile fronthaul links. These links will have seamless connectivity between radio and optical networks because of the low latency of the links, which results from the use of analog signal transmission technology.

“…These would be mounted in locations like lamp posts and billboards where fiber might be not always be available. Therefore, high-capacity wireless millimeter wave (mmWave) links have been proposed as an alternative [4] and are also already available for commercial use.…”

A mobile network employing a so-called cloudbased architecture requires an additional fronthaul network to forward digitized samples. With increasingly dense deployments of small cells, the availability of high quality fiber fronthaul cannot be expected at all sites. Longer fronthaul distances or the employment of wireless technologies renders fronthaul links imperfect in the sense that they introduce bit-errors into the digital samples. In this work, we build upon so-called hardware noise resilient decoders to investigate decoders for imperfect fronthaul that can achieve very good performance even under high bit-error rates on the fronthaul.
