Basic Operation Principle of 802MIP Actiontec Electronics, Inc. 4/2001 The Wireless LAN portion of 802MIP combo card is a 2.4GHz ISM Band DSSS Radio. It is designed to operate using IEEE 802.11b WLAN Standard for use in wireless networking systems. The Radio consists of 4 major ICs, which are ISL3685, HFA3783, ISL3984, ISL3874, and few support ICs. It operates at maximum transmit rate 11Mb/s, back off rates 5.5, 2 and 1 Mb/s. The modulation schemes include CCK (Complementary Code Keying), DQPSK and DBPSK depending on what transmit bit rate it operates at. The radio card interfaces to PC through a MiniPCI bus. Transmitter path The Ethernet data comes through the MiniPCI interface, the Host I/O interface to the MAC section of ISL3874. The signal then flows into the data router where it is converted from Ethernet to 802.11b protocol. After the signal is converted, a radio preamble and header is added to it and passed to the I/O of BBP (Base Band Processor) section of ISL3874 via PHY I/O, RADIO I/O. There is also support circuitry, such as outboard SRAM and flash ROM, which contains the firmware controlling the radio. In TX modulator of BBP section, differential phase shift keying modulation schemes DBPSK, DQPSK and CCK, with data scrambling capability, are fulfilled to provide a variety of data rates--DBPSK for 1 Mb/s, DQPSK for 2 Mb/s and CCK for 5.5 and 11Mb/s. The signal, which now is two separate quadrature components I and Q, then flows to the quad IF chip HFA3783 through D/A converters. At TX side of BBP, there is also TX ALC (Automatic Level Control) circuitry, which is part of the TX ALC loop. The loop keeps TX output power to be consistent so that prevent the power spectrum from regrowth. HFA3783 is now the dual up conversion mixers (dual down conversion mixers for RX). The signal upconverts to an IF frequency of 374 MHz and passes into a variable gain amplifier, which is also a part of the ALC loop. Next, it passes through the switched TX/RX shared SAW filter into ISL3685 and then upconverts again to a RF frequency from 2.412~2.484 GHz, depending on the channel selection. The signal flows through a pre-amplifier, two band pass filters, which block all the unwanted emissions such as image components, harmonics and spurious stuff, into ISL3984 power amplifier. The output of the power amplifier is then fed through another band pass filter that is about 85 MHz bandwidth to one of the antennas. Receiver path The receive signal traveling through the air is received by the dual diversity antennas. The circuits will switch to the antenna which provides better RSSI (Received Signal Strength Indication). The RF signal then feeds into an 85 MHz band pass filter, which blocks all the unwanted components such as image frequency. The signal again is amplified using the LNA within ISL3685 and mixed down to the IF frequency of 374 MHz. The PLL and synthesizer select the channel frequency using Low Side Injection. The mixer outputs are then fed through the IF SAW filter that provides image rejection into HFA3783, which is now a quad down converter. HFA3783 also provides RSSI to BBP of ISL3874. There is a two stage analog AGC (Automatic Gain Control) circuit which adjusts the gain to compensate the signal strength differences. The output of the twin AGC’s provides a constant level signal to the I and Q down converters, which convert the IF to both I and Q signals to BBP. A second frequency synthesizer, which uses ISL3183 as its VCO, feeds the I and Q mixers with a same frequency signal that is phase shifted by 90°. The I and Q signals that are fed into BBP of ISL3874 are converted into digital signals via a dual A/D converters then flow through the digital AGC control circuit followed by the digital demodulator. The correlation codes that BBP generates properly detect the transmitted complimentary codes. In here the automatic antenna selection is also done by taking RSSI as the reference. The output of the digital demodulator is sent into an I/O interface of MAC section. The digital codes then flow into the PHY I/O interface and into the MAC protocol engine. The MAC of ISL3874 converts the signal protocol from 802.11b to Ethernet and finally passes that data through the HOST I/O interface to the PC.

Brief Explanations on Processing Gain Data 1. The formula of Processing Gain is: Gp = (S/N)o +Mj + Lsys Where Gp: Processing Gain; (S/N)o: the ratio of signal energy vs noise power density. Based on the data provided by the chip set manufacturer, it is 16.4dB @11Mb/s, 13.4dB @5.5Mb/s, 13.3dB @2.0Mb/s, 10.3dB @1.0Mb/s; Lsys: test system loss. The measurement result to our test set-up is 2.0dB; Mj: Jamming Margin. It is the ratio of jammer vs WLAN channel signal; 2. The purpose of the measurement here is to figure out Mj at different frequencies. Processing Gain will be gotten through calculation based on the above formula at different frequencies; 3. During the tests (see the Block Diagram of Test Set-up), the input signal to RX is about –60dBm (not exactly at –60dBm) and Mj (dB) = Jammer level (dBm) – Channel signal level (dBm); 4. The criteria we define the transmission link failure is: PER = 8%; 5. FCC defines that when testing the Processing Gain for a specific channel, if the frequency is fo, the jammer frequency has to scan from fo-8.5 MHz to fo+8.5MHz with 50 KHz per step. In another word, 340 data will be taken just for a single channel measurement; 6. Having calculated out 340 Processing Gains for a specific channel, use the percentile average function of Microsoft Excel to figure out the final result. Example: see the first row of 11Mb/s @ Channel 6 Frequency—Jammer frequency = fo-8.5 =2437-8.5 = 2428.50 MHz; (S/N)o—16.4 dB @11 Mb/s (see Item 1); Lsys—2.0 dB (see Item 1); PER— 8.0%, which is the failure criteria; Jammer— -57.2dBm, which is the Jammer level @ PER=8.0%; Mj—Jamming Margin. 5.5 (dB) = -57.2 (dBm) – (-62.7) (dBm) (see Item 3). On here, also see the next page of spread sheet, which shows that XMIT level = -62.7 dBm); Gp—Processing Gain = (S/N)o + Mj + Lsys = 16.4 + 5.5 + 2.0 = 23.9 (dB). After having calculated out 340 Gps, use the percentile function of Microsoft Excel, the final Gp of 11Mb/s @ Ch 6 is 12.9 dB. At the same time, incorporate those 340 data into f—Gp chart, you’ll get a whole picture of it.
