“…In [25], a heuristic method is proposed to place APs in a WCDMA indoor scenario with constraints on iplink (UL) and downlink (DL) SINR performance. All recent studies focus on SINR optimization by different methods (e.g., brute force enumeration in WCDMA [33] and LTE [34], particle swarm in WCDMA [28], and reduction approximation in WCDMA [29]). …”

“…A first criterion is based on pathloss, as proposed in [22,23,31,32]. Two other criteria are based on SINR statistics, taken from [24,25,28,29,33,34]. A fourth new criterion based on cell overlapping is proposed in this paper.…”

“…Thus, many different methods have been proposed to find the best location for macrocellular sites to improve network coverage, user connection quality, and/or network capacity [15][16][17][18][19][20][21]. Similar methods have been used for optimal location of wireless access points (APs) in indoor environments [22][23][24][25][26][27][28][29][30]. All these approaches construct a system model, over which a classical optimization algorithm is applied to find the position of base stations that maximize some overall network performance indicator.…”

Femtocells have been suggested as a promising solution for the provision of indoor coverage and capacity. In this paper, a new planning strategy for placing femtocell access points so as to make the most of automatic traffic sharing algorithms is proposed for a long-term evolution (LTE) heterogeneous network. The aim of the proposed method is to increase overlapping between femtocells by increasing the percentage of area with low dominance of the serving femtocell. Method assessment is carried out by simulating classical traffic sharing algorithms in a three-dimensional office scenario with femtocell location plans designed based on different network performance criteria. Results show that location plans with a larger low dominance ratio achieve better network performance after sharing traffic than plans designed for maximum coverage or connection quality.

“…Also, because of the layout dependency of mmWave networks, due to non-line-of-sight (NLOS) limitations, network planning is more crucial in 5G. Network planning can be divided into two steps [4][5][6][7]: the first is to place many good candidate sites and the second is to select a subset of them to provide coverage. The second step usually uses optimization as its main tool.…”

Millimeter Wave Small Cell Network Planning for Outdoor Line-of-Sight Coverage

The increasing spectrum demand drives next-generation wireless networks to use higher carrier frequencies. The millimeter wave band has orders of magnitude more bandwidth available and is considered as an important candidate for providing most of the capacity in a future heterogeneous network. Moreover, network densification is necessary for enhanced capacity and high-rate coverage. However, deploying a very large number of the base stations might be prohibitively costly. We develop an outdoor small cell millimeter wave network planner and minimize the number of base stations for line-of-sight coverage. This thesis consists of two proposals.First, we estimate the base station densities required for small cell line-of-sight millimeter wave networks. To find the answer, we develop an automatic outdoor network planner by first, placing many candidates on the map and then, selecting a subset of candidates to minimize the total number of base stations and ensure a high percentage outdoor coverage. We run our simulations over two large dense urban areas. Our results show the effects of city layout on the millimeter wave networks.Second, we design a wireless backhaul network planner to further reduce the deployment cost by reducing the number of wired connections in the network. We integrate millimeter wave line-of-sight wireless backhauling into our network planner and minimize the number of wired connections required. The results indicate the advantages of wireless backhauling to reduce the small cell deployment cost.iii
