Abstract

The advent of heterogeneous Broadband Wireless Access Networks (BWANs) has been to support the ever increasing cellular networks' data requirements by increasing capacity, spectrum efficiency, and network coverage. The focus of this chapter is to discuss the implementation details (i.e. architecture and network components), issues associated with heterogeneous BWANs (i.e. handovers, network selection, and base station placement), and also the various resource allocation schemes (i.e. shared resource allocation in split handover and inter-RAT self-organizing networks) that can improve the performance of the system by maximizing the capacity of users.

Architecture

Heterogeneous network (het-net) architecture is a prominent low-cost approach where an operator can exploit the different BWANs to provide additional areal capacity gain, indoor coverage improvement, and improved quality of service (QoS) in the network, as per Yeh et al. (2011).
