"Advanced Wireless Networks 4G Technologies". New E-Book. In the wireless communications community we are witnessing more and more the existence
of the composite radio environment (CRE) and as a consequence the need for reconfigurability
concepts. The CRE assumes that different radio networks can be cooperating components
in a heterogeneous wireless access infrastructure, through which network providers
can more efficiently achieve the required capacity and quality of service (QoS) levels. Reconfigurability
enables terminals and network elements to dynamically select and adapt
to the most appropriate radio access technologies for handling conditions encountered in
specific service area regions and time zones of the day. Both concepts pose new requirements
on the management of wireless systems. Nowadays, a multiplicity of radio access
technology (RAT) standards are used in wireless communications.
