After reviewing the revised test report, the measured peak and average field strengths are within the 15.209 general requirement. Please confirm in writing that you are agreed with this assessment. Best Regards Mike Kuo -----Original Message----- From: Bandele Adepoju [mailto:[email protected]] Sent: Wednesday, June 18, 2003 1:54 AM To: Mike Kuo Subject: RE: Connaught Electronics Ltd, FCC ID:LQN2887, AN03T2678 Hello Mike, The answers to your questions are as follows: Question #4: The manufacturer rates the exact frequency of the LP_Sensor as 5.8GHz. Question #5: The limits stated in 15.249 for out of band emissions are equal to the limits specified in 15.209, which are the general emission limits for non-ISM band operation. This is generally 500uV/m outside of the 15.249 band, and with the operation of the LP_MDD sensor at <10% duty cycle, there is a duty cycle correction for limiting peak emissions per 15.209e, so out of band emissions for the LP_MDD sensor are well below the spurious emissions limits. The out-of-band levels are shown in plots in the attached Report. Question #6: The limits in table have been corrected and a revised report is attached. The 2 limits are for the peak at 5GHz and spurious for out-of-band. Question #7: The pulsed width is 5 nano-seconds. If you should have any additional questions, please do not hesitate to contact me. Thank you for your prompt attention to this response.

The sensor detects motion within a set surveillance hemisphere and an alarm signal is sent to the Ground Module. The sensor works on the Doppler principle. The transmit antenna transmits an electro-magnetic field into the vehicle. The receive antenna accepts reflections from moving targets and the resulting signals are filtered and amplified before being sent to the microcontroller for evaluation. The range is adjustable in software. Thus, the range can always be adjusted to fill the vehicle interior, in relation to the shortest distance between the LP_MDD sensor and the windscreen or vehicle roof (the limits of the vehicle passenger compartment). In this way, a hemispherical field is generated within the vehicle as the area to be monitored. If a large enough change in analog signal amplitude occurs, an analysis of the signal evaluation is started. The microcontroller contains a software algorithm that determines if the signal is a genuine movement or a spurious signal. If this analysis detects significant characteristics of a movement, an alarm is issued to the ground module via the INRS wire line.

When sensitized, it is woken by an interrupt on the ST line. The sensitization period for the SDR module, to full functionality, is 30 seconds. The complete alarm system is likewise ready for operation 30 seconds after sensitization of the DWA (anti-theft warning system). The SDR module operates in impulse mode : that is, like a radar impulse system. An impulse is emitted for a brief period and the reflected signal received is amplified and evaluated. Because the module operates with a very low transmission output, more powerful external frequencies can connect with the receiver side of the device and cause false alarms. The reflected signal is checked in parallel with a suitable EMC protection switching unit and any foreign frequencies are filtered out. Any real movement in the detection area is recognized by a change in the reflection sample. The module emits a pulsed signal and delays this in accordance with the detection range required. This delayed impulse then controls the receiver section. Only after this delay time is the receiver section opened for a short period, when an associated signal pattern is stored. In reality, the detection range corresponds with a spherical "shell" having a width of ca. 5cm. The signal is stored in terms of amplitude and pattern and is compared with the next signal which is received. 1.3 Physical Construction Housing: Frame 3 of 7 FCC ID: LQN2887 LENGTH: 70mm, WIDTH: 63mm, HEIGHT: 29.5mm PCB: Two layer, Board material FR4 Layer 1: Components and signal tracks Layer 2: Ground plane Connector Detail: • 4 way Amp part Number: 4-1393472-9.
