【Abstract】 High requests are needed in EMS(Energy Management Systems).Such as real-time ability,high reliability,etc. And this system should be extended or maintained easily.If Using special line to communicate, such abilities as high speed connection, low transferring delay and large capacity can be aquired. But the great deal of investments,maintaince can’t be accepted. EMS based on LAN(Local Area Networks)has been established in China ,but it is not perfect for EMS. This paper suggests an approach that applying WLAN(Wirless Local Area Networks)in EMS,the protocol is also modified.更多还原
