MULTIPLE ACCESS METHOD FOR WIRELESS LAN FOR A PORTABLE INTERNET AND A WIRELESS LAN IN TWO WIRELESS NETWORK WITHOUT MODIFYING MAC PROTOCOL OF IEEE 802.11

摘要

PURPOSE: A multiple access method for wireless LAN for a portable internet and a wireless LAN in two wireless network without modifying MAC protocol of IEEE 802.11 is provided to implement the coexistence of two networks by preventing the collision of two frequency share.;CONSTITUTION: The presence of 802.11 is determined in an SS(Subscriber Station). If the burst of which a base station uses previous is used, SS transmits data as a CTS(Clear to Send) transfer time. The presence of 802.11 network is identified in the base station(631). The burst of the UL burst previous used emptied is identified(641). The base station transmits CTS in the UL burst. The base station receives a message the transmitted-data of SS after the electrical transmission of CTS.;COPYRIGHT KIPO 2010
