Based on the type of smal celldevices, the 3G and 4G smal cellnetwork models, architectures and network elements are ana-lyzed. It summarized the architecture of smal celland macro cellhybrid network. Then it analyzes six typical deployment sce-narios, which have to satisfy different network deployment requirements corresponding to each scenario. Three practical smal cellnetwork solutions applying for telecom networks are compared in terms of network performance. Several typical backhaul solutions and power supply solutions are listed for network supplement solutions. Final y, the long-term evolution require-ments and the new trends of smal cellnetwork are outlined.
