Table 3 Summary of communication infrastructure in smart grid
Type of network | Function | Characteristic |
|---|---|---|
HAN | Enabling the communication among smart home or office devices and smart meters for local energy management | Deployed at house or small office with a relatively low transmission data rate (less than 1 Kbps) |
NAN | Consisting of several HANs for energy consumption data aggregation and storage at load data center (LDC) | Deployed within area of hundreds of meters with up to 2Kbps |
WAN | Enabling the communication of all smart grid’s components | Deployed within tens of kilometers with high data transmission capability up to few Gbps |
