SMT-R2000 Service Manual © SAMSUNG Electronics Co., Ltd. 1-1 CHAPTER 1. Introduction of SMT-R2000 This chapter introduces SMT-R2000 and describes the configuration and specifications of SMT-R2000. 1.1 SMT-R2000 Overview SMT-R2000 is a wireless LAN Access Point(AP) that is available in the construction of a wireless network and can be used as a wireless LAN repeater. As a wireless LAN repeater, SMT-R2000 is installed within the cell area of AP or the repeater, and re-transmits the data of wireless terminals, such as wireless notebook and wireless PDA, in the outside of the cell area of neighboring AP to AP. Ÿ AP: The AP for wireless LAN is an access device for wireless network connection and performs the relay function among wireless terminals and wired LAN. In general, the AP has a specified use area and a specific frequency. Ÿ Repeater: If AP signal for wireless LAN is transferred over a specified distance, the output signal will be attenuated. Therefore, a device that creates new wave or raises output voltage is required to enlarge the transfer distance. To do so, the wireless LAN repeater is used as a device to restore and relay the transfer signals.
