Heterogeneous wireless networks with small-cell deployments in licensed and unlicensed spectrum bands are a promising approach for expanding wireless connectivity and service. As a result, wireless service providers (SPs) are adding small-cells to augment their existing macro-cell deployments. This added flexibility complicates network management, in particular, service pricing and spectrum allocations...
Unlicensed access to spectrum has the potential to increase competition in spectrum access and encourage innovations by lowering barriers to entry. However, early provider offering service in such a band might use customer contracts which impose a penalty on customers for switching to other providers as a way of creating new entry barriers. Given such contracts, entrant providers must weigh the likelihood...
Sharing spectrum is a promising approach for expanding wireless access and increasing competition among wireless service providers. Indeed, this is a key motivation behind the recent regulations such as those for the 3.5 GHz band in the U.S. However, meeting this promise requires that service providers (SPs) have the incentives to invest in technology to be deployed in shared bands. This is not a...
Modern on-demand networking technologies (e.g., WiFi-Direct) improve users' networking experiences (e.g., enable them to connect to any WiFi enabled devices). Manufactures of wireless devices may choose to provide these technologies to make their products more appealing and charge a higher price. The perceived benefits from these technologies depend on how many other users are in the network, which...
We consider a heterogeneous wireless network serving two classes of users: mobile and fixed. Mobile users can only associate with macro-cells while fixed users can be served by either macro- or small-cells. Multiple service providers (SPs) can operate in the network and each has the same macro-cell infrastructure. In contrast, each SP determines a small-cell deployment density by its investment. Each...
A key feature of many information services is that they exhibit positive externalities or network effects, i.e., the value of the service increases with the number of users. Here, we consider an “open” network, in which a given service may be offered by multiple providers and the positive externality depends on the total number of customers served by all providers. Providers compete for customers...
Motivated in part by the success of WiFi, there has been much interest in opening up new “prime” bands of spectrum for unlicensed use. Such bands can lower the cost for new wireless service providers to enter a market. The increased competition could in turn improve economic welfare. However, the openness of such spectrum can also lead to it becoming over congested, which in turn could deter investment...
Opening “prime” spectrum to unlicensed usage can lower the costs for offering wide area wireless services but may also lead to greater congestion due to multiple providers operating in the same band. To mitigate congestion, service providers may invest in more infrastructure or better technology. The costs of such investments must be weighed against the potential gains in revenue, which in turn will...
