Based on CoMP use cases, which have been discussed in detail, various architecture options and tradeoffs relating to the implementation of SoN are solved. This helps meet capacity enhancement. The benefits include the CoMP convergence trend that integrates wireless small cellular adoption, along with modularization and interoperability technologies. SCE systems can effectively meet the reliability, compatibility, and performance needs of this infrastructure, and Telecomm operators believe this will address the question of the last mile transmission network. Small cell enhancements (SCEs) have the unique advantage of improving capital expenditure (CAPEX) issues for operators due to low capital costs, the promise of a fast roll out of new services, and the low implementation risk associated with trying out these systems. Compared to employing equipment for a massive macro cell environment, which would require significant amounts of money and increase risk, operators enjoy the advantages of an evolution towards systems organized within the three quadrants shown in Figure 1. The CoMP architecture for incorporating SoN network solutions into SCE systems for IoT applications within the novel usage environment is shown in Figure 2.  
The theory of SCE infrastructure includes a carrier transmission current line between the substation and the user end device. A SCE is a modularized flexible expansion of subsystems that transmit radio frequency energy via fiber conduction or spectrum radiation [10; 11]. \begin{table}

Operators would normally obtain these benefits by distributing responsibilities among several multi-operator indoor system projects. This thesis instead investigates SCE systems, applying multiple distribution points for remote radio technology in cellular communication systems within the Metro, High-Speed Railway, and Subway environments, to conduct an analysis of public coverage using a novel indoor transmission system.
