Introduction: Basically speaking, the schematics could be separate in two parts: Analog Part: Including RF3000, RF2494, RF2948B, Si4126,AR0213B Digital Part: Including RF3000, AT76C510 ,IDT71V424, AT29LV040, MX824R, ATF1504ASV This document contains circuit operation theory for Wirless LAN Access Point. The Procomp Wireless LAN Access Point is a flexible data communications facility implemented as an extension to, or as an altemative for, a wired LAN. Using radio frequency(RF) connections. Thus, wireless LANs combine data commectivity with user mobility. Figure 1. shows a simplified block diagram of the Wireless LAN Access Point. Figure 1. Wireless LAN Access Point Block Diagram Wireless LAN Access Point Operational Description 4 2. About AT76C510 2.1 General Description A block diagram that is based on the AT76C510 (Bridge-on-a-Chip) performs the inter-networking between Ethernet and IEEE802.11b Wireless LAN is shown in Figure 2. The three more modules for allowing compact system implementation, flexibility for supporting almost all possible physical interfaces and thus reducing the system cost are the Ethernet PHY, the Wireless PHY and the RAM modules. AT76C510 receives data from both networks, stores them locally for further processing, installs and maintains connections and transmits the packets to the proper destination. In order to implement such a device, a high processing power CPU is required along with the two network interfaces. At the WLAN side, AT76C510 the two different physical layers (PHYs) described at the IEEE802.11b standard, namely the Direct Sequence (DS) and Frequency Hopping (FH, at 2 Mbps) PHYs. At the Ethernet side, a standard MII interface port is integrated into the chip along with the main bridge functions. This port is independent from the actual physical layer and allows the use of ready-made, well proven design modules for various 802.3 physical interfaces. Expansion of the wireless network area coverage is possible by means of the so called (according to the 802.11b standard) Access Points (AP). Multiple APs link the WLAN to the Ethernet and allow users to efficiently share network resources. The APs not only provide communication with the Ethernet network but also mediate wireless network traffic in their immediate neighborhood. Multiple access points/bridges can provide wireless coverage for an entire building or campus. Bridge functions and management is a challenging task due to the non-deterministic behavior of the traffic generally used in Multimedia data communications with the mix of isochronous services. Wireless LAN Access Point Operational Description 5 Figure 2. Typical Bridge-on-a-Chip System 2.2 Bridge Internal Data Flow This section presents the data flow inside the chip and describes how the various modules are used for supporting it. Figure 3 shows a detailed description of the data flow at the Ethernet to WLAN direction, while Figure 4 shows the data flow at the WLAN to Ethernet direction. When a packet is received at the Ethernet side, the following steps are…

Complete description and measurement data have been placed on file with the commission. The conducted power line emissions tests and other test items were performed in a anechoic chamber also located at Training Research Co., Ltd. No. 255 Nanyang Street, Shijr, Taipei Hsien 221, Taiwan, R.O.C. Training Research Co., Ltd. is listed by the FCC as a facility available to do measurement work for others on a contract basis. 1.9 General Test Condition The conditions under which the EUT operates were varied to determine their effect on the equipment's emission characteristics. The final configuration of the test system and the mode of operation used during these tests were chosen as that which produced the highest emission levels. However, only those conditions, which the EUT was considered likely to encounter in normal use were investigated. In test, they were set in high power and continuously transmitting mode that controlled by computer. The ch01, ch06 and ch11 of EUT were all tested. The setting up procedure is recorded on <1.3> test method.

Section 15.207: Power Line Conducted Emissions for AC Powered Units 3.1 Test Condition & Setup The power line conducted emission measurements were performed in an anechoic chamber. The EUT was assembled on a wooden table, which is 80 centimeters high, was placed 40 centimeters from the backwall and at least 1 meter from the sidewall. Power was fed to the EUT from the public utility power grid through a line filter and Line Impedance Stabilization Networks (LISNs). The LISN housing, measuring instrumentation case, ground plane, etc., were electrically bonded together at the same RF potential. The Spectrum analyzer (or EMI receiver) was connected to the AC line through an isolation transformer. The 50-ohm output of the LISN was connected to the spectrum analyzer directly. Conducted emission levels were in the CISPER quasi-peak detection mode. The analyzer's 6 dB bandwidth was set to 9 KHz. No post-detector video filter was used. The spectrum was scanned from 150 KHz to 30 MHz. The physical arrangement of the test system and associated cabling was varied (within the scope of arrangements likely to be encountered in actual use) to determine the effect on the unit's emanations in amplitude and frequency. All spurious emission frequencies were observed. The highest emission amplitudes relative to the appropriate limit were measured and have been recorded in paragraph 2.4. There is a test condition applies in this test item, the test procedure description as the following: The setting up procedure is recorded on <1.3>. Three channels were tested, one in the top (CH01), one in the middle (CH06) and the other in bottom (CH11). 3.2 List of Test Instruments Calibration Date Instrument Name Model No. Brand Serial No. Last time Next time EMI Receiver 8546A H P 3520A00242 06/28/02 06/28/03 RF Filter Section 85460A H P 3448A00217 06/28/02 06/28/03 LISN (EUT) LISN-01 TRC 9912-03,04 06/04/02 06/04/03 LISN (Support E.)
