ABSTRACT
At present, various wireless communication systems have formed many relatively independent networks, including a variety of standard cellular mobile networks, wireless local area networks (LANs), wireless digital home networks, and vehicle wireless communication systems. ese network patterns are longitudinally independent; each network has its own specific resource composition and, based on the cyber source, provides a specific function and application. Such a network pattern has gradually exposed its inherent problems: a variety of complex protocols, complex wireless coexistence, and very high wireless network management and maintenance costs. e system design and performance evaluation of the ird-Generation Partnership Project (3GPP) Long Term Evolution (LTE) radio access networks have so far been generally based on homogeneous cell layouts. Figure 7.1 illustrates a basic homogeneous deployment where each hotspot is covered by many high-powered nodes (i.e., a macrocell) with equal transmission power.
