“…However, since eMBMS is not yet widely deployed, this work considers a UC transmission for the BB network. Indeed, it was shown that UC could achieve significantly high coverage rates with a proper allocation of available resources [38]. In contrary to the previous works in [13,[28][29][30]] where a grid model was used to describe the BB network, a more accurate PPP is used here to model BSs positions.…”

Following the increasing growth in the demand on mobile TV, hybrid broadcast/broadband networks emerged as a suitable approach to overtake the challenges introduced by each network separately in order to enhance users' experience. This paper presents two possible scenarios for a hybrid, spatially separated, broadcast/broadband network to offer mobile TV linear services for the end users. Namely, the first scenario is based on shared spectrum access for both networks while the second one proposes a dedicated spectrum. Using a stochastic geometry approach, the paper derives analytical formulations for both the probability of coverage and ergodic capacity. These formulations are then used to optimize the hybrid network in terms of its key design parameters including the broadcast (BC) coverage radii, the broadband (BB) base stations' (BS) density, and spectral capacity. The results have shown that an optimal BC radius maximizing the probability of coverage and capacity exists and it depends on the BS density of the BB network. Other design parameters have been provided and analyzed leading to an optimal network deployment. To the best of the author's knowledge, this paper presents a first reference work dealing with the optimization of the hybrid network with the coexistence of broadband and broadcast networks, from stochastic geometry perspective, taking into account the inter-cell interference.

“…BB networks covers large service areas divided into relatively small cells with relatively low transmission power. In each cell, service delivery is conventionally carried out using the Unicast (UC) mode in which the spectrum resource is shared and distributed to users [6]. With unicast, BB networks are very efficient to individualize the service delivery but may suffer from overload issues when a large number of users are demanding for high bandwidth services [7].…”

Hybrid broadcast/broadband network (HBBN) presents a potential solution to mitigate the increasing demand for mobile TV. A proper HBBN deployment alleviates the limitations that each standalone network faces, thereby enhancing the global network coverage and efficiency. In this paper, we propose to address the question of performance improvement expected from such HBBN by means of an analytical framework based on stochastic geometry modeling. To this end, we introduce a generic model of the HBBN where multiple broadcast transmitters and a broadband network are deployed in the same area, jointly offering linear services, one of the mobile TV services. Two different approaches derived from stochastic geometry are applied and compared through the analysis of what is commonly referred to as a Point Hole Process (PHP): Original Poisson Point Process (PPP), and reduced PPP. Both approaches are thoroughly analyzed to give better insights into broadcast/broadband coexistence while taking into account the inter-cell interference of both networks. Exact and simplified expressions for the key performance metrics are derived such as the probability of coverage and ergodic capacity. Those expressions are then used to numerically maximize the spectral and power efficiency of the HBBN regarding the broadcast coverage radius and transmitters' density. The results show that for a wide range of user density, the HBBN introduces gain compared to either BB or BC networks. To the best of the authors' knowledge, this paper presents the first work dealing with the optimization of HBBN based on such a generic model and taking inter-cell and internetwork interference into consideration.

“…In this work, we study the power energy efficiency for a user-dense spatially separated hybrid network, using microcells for the broadband subnetwork, taking inter-cell interference into consideration, utilizing stochastic geometry tools with a Poisson Point Process (PPP) to model the broadband network. The resource allocation scheme is proposed in [8] and adopted here on top of the stochastic geometry approach to design a power efficient hybrid network. The problem is set to minimize the power consumption per served user by managing the key design parameters like BC radius and UC BS's density.…”

The demand on linear services like mobile TV has been growing during the last few years, creating challenges to the conventional methods of delivery such as broadcast networks and broadband mobile networks. In this paper, a hybrid approach with the coexistence of a broadcast transmitter and a unicast broadband transmitter is discussed, and the problem of the power consumption and power efficiency is interpreted. To achieve an efficient hybrid network in terms of power consumed to serve a user, the hybrid network is numerically optimized in terms of key design parameters like the broadcast radius and the base stations' density. The effect of user density is also studied highlighting the gain expected when using the hybrid approach. Results have shown that an optimal operation point could be found, and that the gain provided by the hybrid network depends on the density of the users.
