“…The region of 1 km 2 area, is decomposed as shown in Figure 2 at base station level, where red dots represent the base stations and the surrounding polygons represent the Voronoi cells. 4 We analyze the data in a normal working day from 8 am to 10 am when people make their regular home-to-work travel. We choose this period to capture users mobility in the chosen region.…”

“…Such solutions aim to optimize the resource utilization reducing the traffic on operator's licensed spectrum, and lowering the traffic load on base stations. Wi-Fi technology has always been an attractive solution for data offloading because of the ubiquity of Wi-Fi networks, the high bit rates they provide, the simplicity in deployment and maintenance, and the lower CAPEX [4]. Until the Wi-Fi Certified Passpoint Program (also known as 'Hotspot 2.0' and referred to in the following shortly as 'Passpoint') [5], the WiFi technology was lacking of seamless interworking 2 A C C E P T E D M A N U S C R I P T between Wi-Fi and mobile cellular networks on the one hand and between Wi-Fi hotspots on the other hand.…”

Wi-Fi technology has always been an attractive solution for catering the increasing data demand in mobile networks because of the availability of WiFi networks, the high bit rates they provide, and the lower cost of ownership. However, the legacy WiFi technology lacks of seamless interworking between Wi-Fi and mobile cellular networks on the one hand, and between Wi-Fi hotspots on the other hand. Nowadays, the recently released Wi-Fi Certified Passpoint Program provides the necessary control-plane for these operations. Service providers can henceforth look to such Wi-Fi systems as a viable way to seamlessly offload mobile traffic and deliver added-value services, so that subscribers no longer face the frustration and aggravation of connecting to Wi-Fi hotspots. However, the technology being rather recent, we are not aware of public studies at the state of the art documenting the achievable gain in real mobile networks. In this paper, we evaluate the capacity and energy saving gain that one can get by offloading cellular data traffic over Passpoint hotspots as a function of different hotspot placement schemes and of access point selection policies (two enabled by the Passpoint control-plane and one independent of it). We compare the policies using real mobile data from the Orange network in Paris. We show that offloading using Passpoint control-plane information can grant up to 15% capacity gain and 13% energy saving gain with respect to Passpoint-agnostic ones based on signal quality information. As of placement strategy, installing Passpoint hotspots in the outer annulus of the macrocell coverage grants the maximum capacity gain.

“…Among other a key disadvantage of 3G cellular networks are the associated regulatory issues as well as the high costs associated with the service. As [14] points out 3G cellular networks are based on a vertical and centralized business framework with which users solely act as clients without much possibilities of actually participating in the provision process. Furthermore internet provision through 3G infrastructure faces considerable technical and legislative challenges in developing countries.…”

Abstract. Provision of internet access in infrastructure deficient areas is expected to bring profound economic and humanitarian benefit to developing countries. Notwithstanding, achieving this goal poses an economic and technical challenge. Due to technological and economical reasons cellular networks are regarded to be unable to deliver affordable distribution in the short term. Instead 802.11s wireless mesh networking standard is identified to be a more viable and affordable partial solution to deliver broadband internet in the periphery of developing countries. A general focus is the individual incentive to participate in a mesh network rather than reliance on organisational bodies. This paper designs an architecture and business model for a low cost, low range distribution of internet access. The technical architecture is evaluated using simulation and is found to be viable, but demands optimisation.

“…By about 2008 this had begun to fail in the US (Wu 2007, Fraser 2009, Economist 2013 because of the technological and regulatory challenges associated with providing seamless coverage, but also for cost and convenience factors owing to competition from next generation (3G and 4G) broadband networks (Lehr andMcKnight 2003, Yaiparoj et al 2008) as well as increased coverage by private providers of WiFi.…”

Economics of Public WiFi

Local governments in urban regions continue to find the idea of public or municipal WiFi attractive. This is for multiple reasons, not all of which are based on economic logic (such as city branding, vote-buying, emergency services, commercial lobbying, peak-traffic broadband off-loading). However, the purpose of this paper is to gather together the basic economic arguments for and against public provision of municipal WiFi. First, we consider what type of economic good WiFi is, and the logic for public rather than market provision. Second, we review four main economic arguments against public WiFi (capitalization; no market failure; competitive distortion; inefficiency of supply side response). Finally, we consider what may be the strongest, yet least made, case for publicly funded municipal WiFi, which is local demand discovery as an implicit subsidy for WiFi entrepreneurship and innovation.
