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...
Small-cell deployment in licensed and unlicensed spectrum is considered to be one of the key approaches to cope with the ongoing wireless data demand explosion. Compared to traditional cellular base stations with large transmission power, small-cells typically have relatively low transmission power, which makes them attractive for some spectrum bands that have strict power regulations, for example,...
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...
We consider a wireless network in which multiple Service Providers (SPs) compete to provide both macrocell and femtocell services in different bands. There are two types of users: mobile users that can only connect to macrocells, and fixed users that can be served by both macrocells and femtocells. For a given allocation of bandwidths across SPs, we characterize for each SP the optimal bandwidth split...
We consider a large wireless network with both heterogenous transmitters and receivers. The transmitters consist of large (macro) cells which have large transmission power and small (femto) cells with much smaller transmission power. The receivers consists of highly mobile users, which are better served by macrocells and fixed users, which can be served by either macrocells or femtocells. We study...
