CHAPTER 1.Overview OfficeServ 500 Wireless LAN Service Manual/Ed.00Page 1-18 © SAMSUNG Electronics Co., Ltd.3.5.2 WIP-5000M Block DiagramFigure 1.5 Block Diagram of WIP-5000MThe WIP-5000M is largely divided into 3 parts as below :Wireless LAN PartThe wireless method used for the WIP-5000M is the IEEE802.11b Wireless LANspecification at the 2.4GHzbandwith.Also, the major components of wireless LAN are the Prism2.5 of Intersil, and arecomposed of 4 components, such as ISL3984(PA), HFA3783(IF I/Q MOD. DEMOD.),ISL3685, and MAC/BBP ISL3873B.CPU, VoIP (SIP) PartThe CPU used for the WIP-5000M is a combined type that the RISC and DSPfunctions are combined into one processor. That is, there is no need for a separateDSP when processing voice for the Voice over WLAN. Also, the internal SRAMallows the program performance possible without a separate external memory.The major functions for the main processor are summarized as the wireless LAN,control of other major components, processing of voice codecs, and echo removal.The user interface partThe user interface part can provide various and convenient functions using graphicLCDs and navigation key.BPFPAIF/MOD BBPMACRF/IFConvF/ROMPCMCIACPLDMPUNetergyFlash MEMCODEC MMIINTERFACEReceiverMICGraphic LCDKey-padBatteryVibratorChargingCradleHeadSetWLAN(802.11b) Part CPU, VoIP(SIP) Part User Interface Part
