FCC ID LABEL LOCATION

FCC ID: PD5LMWS110 ADT No.90021902 Operational Description The transmitter of the EUT (11Mbps Wireless Access Point) is powered by power adapter and connected with notebook through RJ45 port. The antenna is Dual Monople Antenna, there is no antenna connector . Under normal use condition, the user has to keep at least 20cm separation distance between radiator and the body of the user. The other instruction, please have a look at the users manual.

FCC ID: PD5LMWS110 Report No.: RF900219021Issued: March 2, 2001 ANNEX 2 DSSS INFORMATION This device is Direct Sequence Spread Spectrum, the data is mixed by pseudorandom code which is an orthogonal code. The mixed data is digital modulated by BPSK and QPSK technique depends on the data rates. The CCK coding is applied for increasing the data rate, and also the processing gain will be increased. The bit rates are 1,2,5.5,11Mbps, the symbol rates are 1,1,1.375,1.375Mbps, the chip rates are always 11Mbps. So, the Chip/symbol is 11,11,8 and 8 respectively. Although is higher bit rate, the processing gain is lower than 10, but the CCK coding used in higher bit rate will provide 2.2dB coding gain.

Section 4.7.4 shows the test configuration. The test consists of stepping a signal generator in 50 kHz increments across the passband of the system. At each point, the generator level required to produce the recommended Bit Error Rate (BER) is recorded. This level is jammer level. The output power of the transmitting unit is measured at the same point. The jammer to Signal (J/S) ratio is then calculated. Discard the worst 20% of the J/S data points. The lowest remaining J/S ratio is used when calculating the Process Gain. The reference PER is specified as 8%. The corresponding Es/No (signal to noise ratio per symbol) is 16.4 dB. The curve is attached as below. This value and the measured J/S ratio are used in the following equation to calculate the Process Gain (Gp) of the system. Where: (S/N) o : Signal to noise ratio for the chosen BER. Gp = (S/N) o +Mj+Lsys FCC ID: PD5LMWS110 Report No.: RF90021902 3 Issued: March 2, 2001 Mj : Maximum jammer to Signal Ratio recorded at the detected BER. Lsys : System losses . For the purpose of this processing gain calculation, we assume Lsys at its minimum value of 2 dB.

Perform all independent instrumentation calibrations prior to this procedure. Set operating power levels using fixed and variable attenuators in system to meet the following objectives: Signal Power at receiver approximately –55dBm (above thermal sensitivity such that thermal noise does not cause bit errors. Signal Power at power meter between –20 and –30dBm for optimal linearity. Use spectrum analyzer to monitor test. Ensure that CW Jammer generator RF output is disabled and measure the power at the power meter port using the power meter. This is the relative signal power, Sr. Disable Transmitter, and set CW Jammer generator RF output frequency equal to the carrier frequency and enable generator output. Set reference CW Jammer power level at power meter port 8.4dB below Sr (minimum J/S, or 10dB processing gain reference level). Note the power level setting on the generator, this is the reference CW Jammer power setting, Jr. Disable CW Jammer, re-establish link. PER test should be operating essentially error -free. Enable CW Jammer at the reference power level and verify that the PER test indicates a PER of less than 8%. Alternatively, adjust the CW Jammer level to that which causes 8% PER and verify that the S/J is less than 8.4dB. Repeat step 7 for uniform steps in frequency increments of 50 kHz across the receiver passband with the CW Jammer. In this case the receiver passband is +/- 8.5 MHz. The numerical data associated with the following radio channel is tabulated and presented for Channel 1,6, and 11. Note:Since the jamming signal will be blocked by the IF filter if the jamming frequency is far form the center of the carrier frequency. So, only those frequencies ar…
