Dwyer" <[email protected]> cc September Radecki <[email protected]>, Mike Kuo <[email protected]> date Oct 23, 2007 1:02 PM subject RE: Proxim Wireless Corporation, FCC ID: HZB-MP50XXSU, Assessment NO.: AN07T7272, Notice#1 Hi Tim, Below are the answers to your questions on this application. Q1: Please revise the label to include the statement of 15.19. <CCS ANSWER:> Revised ID Label and Location Exhibit is attached. Q2: Please revise the user manual to include appropriate user information, installation conditions, and RF exposure statements. <CCS ANSWER:> Please see attached revision which will be included with the manual. Q3: Test setup photos were provided only for the DFS tests. Please provide wireless conducted and radiated test setup photos for testing associated with both the IXM and AP700 reports. <CCS ANSWER:> There are two additional test setup exhibits attached. Q4: 5745-5825MHZ is listed for this 15E NII application. 5825 MHz is a 15E band-edge, so this frequency range specification is not possible under 15E. Additionally, the application is for 15E but the IXM test report submitted to cover the range is for 15C. 15E compliance is not shown in the 15C report for 5745-5825 MHz.. The AP700 report shows only 15E compliance for 5470-5725 MHz. The IXM report shows 15E compliance for 5150-5350 MHz. Please provide additional explanation or revised test reports. <CCS ANSWER:> Yes, this band should have been on the DTS application. Additional reports attached. Q5: The block diagram and schematics describe a device with 4 coaxial ports. From photos and other information, this device appears to have only a single coaxial port. Please provide some additional explanation. <CCS ANSWER:> HZB-AP700 uses one AR5112/2112 radio only, the other AR5112/2112 radio shown on the block diagram is depopulated. So there are only two antenna ports. The diference between HZB-AP700 and HZB-MP50XXSU is that HZBMP50XXSU uses only one antenna connector while HZB-AP700 uses two antenna ports. Q6: Please provide RF Exposure MPE evaluation data for this application. <CCS ANSWER:> Please see attached RF Exposure Report.

There is one issue that needs to be clarified before the review can be completed. The review for the composite DTS application AN07T7290 is nearly complete. Some issues for this application will be repeated in that one, but aside from those, the DTS application appears to be ok. I am sending this notice separately in the interest of expediting the process. Q1: Please revise the label to include the statement of 15.19. Q2: Please revise the user manual to include appropriate user information, installation conditions, and RF exposure statements. Q3: Test setup photos were provided only for the DFS tests. Please provide wireless conducted and radiated test setup photos for testing associated with both the IXM and AP700 reports.

ADDRESS: 141, Lane 351, Taiping Road, Sec. 1, Tsao Tuen, Nan-Tou, Taiwan, R.O.C. ISSUED BY: Advance Data Technology Corporation LAB LOCATION: No. 81-1, Lu Liao Keng, 9 Ling, Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien, Taiwan, R.O.C. Lab Code: 200376-0 Report No.: 921107R01 2 RF Exposure Measurement 1. Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500 ... ... F/300 6 1500-100,000 ... ... 5 6 (B)Limits For General Population / Uncontrolled Exposure 300-1500 ... ... F/1500 6 1500-100,000 ... ... 1.0 30 F = Frequency in MHz Report No.: 921107R01 3 3. Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1 mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance 20cm. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. Classification This device is not fixed inside the host equipment, it is connected with host through wire. So it is easy to be re-located in the place where at least 20 cm far away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device. Report No.: 921107R01 4 6. Test Results 6.1 Antenna Gain Antenna 1: The maximum Gain of the antenna is 2.5dBi. Antenna 2: The maximum Gain of the antenna is 2.0dBi. Antenna 3: The maximum Gain of the antenna is 3.0dBi. Antenna 4: The maximum Gain of the antenna is 10.0dBi. Antenna 5: The maximum Gain of the antenna is 14.0dBi.
