“…The generic costs associated with key infrastructure entities are listed in Table IV. It is worth mentioning that the costs highlighted are assumptions estimated from various references [18], [33], [34] and might vary to a limited extent in terms of market value. Figure 4 shows how rural Internet connectivity can be made practicable with 5G-TVWS backhaul in comparison with conventional approaches, where optical fiber is used.…”

Abstract-The cellular technology is mostly an urban technology that has been unable to serve rural areas well. This is because the traditional cellular models are not economical for areas with low user density and lesser revenues. In 5G cellular networks, the coverage dilemma is likely to remain the same, thus widening the rural-urban digital divide further. It is about time to identify the root cause that has hindered the rural technology growth and analyse the possible options in 5G architecture to address this issue. We advocate that it can only be accomplished in two phases by sequentially addressing economic viability followed by performance progression. We deliberate how various works in literature focus on the later stage of this 'two-phase' problem and are not feasible to implement in the first place. We propose the concept of TV band white space (TVWS) dovetailed with 5G infrastructure for rural coverage and show that it can yield cost-effectiveness from a service provider's perspective.

Inclusion of statistical knowledge of the primary user (PU) channel usage had shown to be beneficial in dynamic spectrum access. Motivated by this fact, this paper investigated the importance of collecting and using statistics on neighboring secondary users (SUs) in selecting channels in addition to the knowledge of PU channel usage. The paper assumed that PU traffic characteristics of the channels are included in the radio environment map in the form of probabilistic suffix trees, which is a sequence predictor based on Markov property. In the proposed method, an intelligent sequence hopping-based common control channel and a carrier sense multiple access (CSMA)/collision avoidance (CA)-based medium access control (MAC) protocol were introduced. As shown in the paper, selecting channels using statistics of both the neighboring SUs and PUs reduced the number of packet collisions compared to a scheme which only uses PU statistics. Furthermore, the simulation results showed that the scheme proposed had better throughput performance with respect to both the random channel selection scheme and the scheme which only uses PU statistics while having less training complexity.

“…small cell sizes) it is possible to efficiently exploit the secondary spectrum. The operation of a spectrum broker that assigns TVWS bands is presented in [5] considering the problem of matching multiple-bids to buy, and spectrum portfolio (offered by a spectrum broker). In turn, in [6] an auction approach for using TVWS with LTE and LTE-A is proposed.…”

In this paper, we consider allocation of spectrum resources in the so-called TV White Spaces (TVWS) to small cells for their realistic deployment based on first-come, first-served principle. Three allocation rules are analyzed with a focus on channel bartering between the neighboring cells. Simulation results show that neighborhood cooperation can improve the performance of spectrum allocation in terms of the efficiency of spectrum and power resource usage. Moreover, cooperation with more distant cells significantly improves this performance at the expense of complexity. 1
