“…It is clear that main focus in 5G communications would not be only on providing additional throughput for a single user. The focus will move to solving radio interface and spectrum saturation in situations with very high user density and large number of data sessions and voice calls that are made from very small areas, [2]. Mobile operators are seeing capacity hungry user environment that considers high data rates over wireless system as ubiquitous service although radio spectrum is a scarce resource.…”

Integration of wideband joint spatio-temporal spectrum sensing in wireless cellular system (coherent and non-coherent variant) is proposed as preliminary innovative idea. It provides that cellular systems as licensed users should use unoccupied licensed frequency bands assigned to other licensed users. Such cognitive properties integrated in cellular systems should improve their performances both on the level of macro as well as femtocells. Some challenges and system aspects of such integration are shortly highlighted.

“…GSM, HSPA) subscribers to LTE-A, the bandwidth requirements of LTE-A networks to support a minimum QoE level to their users also increase. Furthermore, since less users access the legacy RATs, a large amount of spectrum dedicated to them is left underutilized and although next generation solutions are slowly taking shape, it is evident that a single (new) radio technology can not guarantee the efficient reuse of spectrum [2] [3].…”

Next generation wireless networks are becoming the main focus of the industry by putting efforts to launch beyond 4G (i.e. 5G) communication systems by 2020. Towards the 5G-system vision, the efficient spectrum aggregation by integrating multiple radio access technologies (multi-RAT) is one of the enablers to achieve the highest data rates. To this end, a multi-RAT aggregation is envisioned that can be provided using the spectrum reallocation technique. Spectrum reallocation among multi-RATs can provide spectrum opportunities for aggregation and, thus, the overall spectrum utilization and network capacity increase. Maintaining an optimum quality of experience (QoE) for users of different RATs in such an extremely complex network environment can be facilitated by such a multi-RAT aggregation (spectrum aggregation from different RATs), through spectrum reallocation. To this end, both network and functional architectures are specified and spectrum assignment solutions are proposed in this article. The goal is to efficiently increase the data rates supporting a required QoE for all users.

“…These solutions have been seen as potential solutions for deployment of wireless networks with large coverage footprint that could serve users both in indoor and outdoor environment. There has been extensive analysis related to 3G and 4G networks [5] performances and some research related to IEEE 802.11af technology [6] and in general technology intended for TV White Space (TVWS) [6,7]. Nevertheless, direct comparison on multiple criteria has not been performed in order to estimate in what scenarios is each of these technologies a better solution for underserved and low income end users.…”

Comparison of TVWS solutions based on TDD LTE and IEEE 802.11af has been presented. It can be concluded that both technologies provide option for deployment in UHF TV band but selection should be made on multiple criteria such as type of end users, required technical parameters and overall price of the deployment. It is shown that proposed solutions could serve for alternative wireless broadband access in developed countries as well for underserved and low income population. It can be concluded that IEEE 802.11af will be superseded by IEEE 1900 standard based solutions in order to improve its' communication and coexistence performances while TDD LTE could be a better solution regarding throughput and costs of deployment if sufficient spectrum is available.
