Applicant: ITRONIX, Corporation FCC ID: KBCIX300AC775WLBT Simultaneous Transmit of Co-located Transmitters Applicant: ITRONIX, Corporation FCC ID: KBCIX300AC775WLBT Model: IX300 FCC REQUIREMENT FOR SIMULTANEOUS TRANSMISSION Excerpt below from TCB Question 7 for FCC, FCC / TCB Workshop 10-23-02 Day 2. “The radios must be tested individually. Assuming that the radios do not share an antenna, only radiated tests for simultaneous transmission is required. If the radios share an antenna, antenna conducted measurements would also be required. Only one set of worst case simultaneous transmission data is going to be requested to be submitted at this time. The test engineer should indicate the worst case condition and provide justification as to why the worst case condition was chosen. The grantee should be reminded that even if the FCC requests one set of data, they are responsible for compliance for all modes of simultaneous transmission. Aggregate power must be considered in RF exposure evaluation.” DISCUSSION: The IX300 contains a Sierra Wireless AirCard 775, is a dual band radio with Cellular, GSM850 and PCS1900 transmitter co-located with an 802.11, WLAN, and a FHSS Bluetooth Intentional Radiator. The three radios can transmit simultaneously. Therefore, while simultaneously transmitting the spurious emissions from the above referenced device were compared to the Part 22.917(e) and the 24.238(a) limits for the transmitter and to the Part 15.247(c) limit for the Bluetooth Intentional Radiators. The radios do not share antenna. The AirCard 775 has its own external antenna. Both Intentional Radiators have their own antenna internally integrated within the IX300 terminal. Initially measurements were made with the AC775 and WLAN and Bluetooth simultaneously transmitting on there respective low, mid and high channels. Then measurements were made with the WLAN and Bluetooth simultaneously transmitting on the same low, mid, and high RF channels, as well as the AC775 transmitting on its low mid and high channel. The final measurement results are reported on pages 3 to 6 following. Exhibit 6 1

Applicant: ITRONIX, Corporation FCC ID: KBCIX300AC775WLBT Additionally, the various channel combinations for the PCS bands used by the GPRS transmitter and the WAN and Bluetooth Intentional Radiator channels were mathematically compared for any harmonic frequency combinations that happen to fall on exactly the same frequency. Additional measurements were made on these specific channel combinations to investigate the possibility of increased emission level with the simultaneous transmit. We expect that the likelihood of an increase in the harmonic emission level would exist when the combined harmonic energy from two sources is present on the same frequency. It appears that this situation could occur with at least the following two frequency combinations noted below. In this case however, levels are too low to be measurable. WAN & Bluetooth set to 2412 MHz 7th harmonic), with the PCS set to 1876 MHz (9th harmonic) 16844 MHz No emission was measurable at one half meter EUT to antenna distance, more than 20 below the 15.247 (c) limit. WAN & Bluetooth set to 2437 MHz (7th harmonic), With the PCS set to 1896 MHz (9th harmonic) 17066 MHz No emission was measurable at one half meter EUT to antenna distance, more than 20 below the 15.247 (c) limit. The following three pages report the other simultaneous transmission emissions findings discussed previously on page one. Pages 3 & 4.)
