Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired sys- tems. WLANs are flexible and easy to setup and manage. They are also more economical than wired LAN systems. Using radio frequency (RF) technology, WLANs transmit and receive data through the air. WLANs combine data connectivity with user mobility. For example, users can roam from a conference room to their office without being disconnected from the LAN. Using WLANs, users can conveniently access shared information, and network administrators can configure and augment networks without installing or moving network cables. WLAN technology provides users with many convenient and cost saving features: • Mobility: WLANs provide LAN users with access to real-time information anywhere in their organiza- tion, providing service opportunities that are impossible with wired networks. • Ease of Installation: Installing is easy for novice and expert users alike, eliminating the need to install network cables in walls and ceilings. • Scalability: WLANs can be configured in a variety of topologies to adapt to specific applications and installations. Configurations are easily changed and ra…

FCC ID: O6M-WM302 ADT No.910527R02 Operational Description The transmitter of the EUT (11Mbps Wireless LAN Module) is powered by host equipment via a PCMCIA interface. The antenna is dipole and printed antenna, and the antenna connector type is MMCX. 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. 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.

ADDRESS: No.20, Kuang Fu Road, Hsinchu Industrial Park Hukou, Hsinchu, Taiwan, R.O.C. ISSUED BY:Advance Data Technology Corporation LAB LOCATION:47 14th Lin, Chiapau Tsun, Linko, Taipei, Taiwan, R.O.C. 0528 Lab Code: 200102-0 FCC ID: O6M-WM302 ADT No.: 910527R02 RF Exposure Measurement (Mobile Device) 1. Introduction 2.4 GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. 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), and 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. 2. Classification The antenna of the product, as the warning statement on users manual, is at least 20 cm away from the body of the user. Warning statement for keeping 20 cm separation distance and the prohibition of operating next to a person has been printed on the users manual. So, this product is classified as the Mobile Device. 3. 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). FCC ID: O6M-WM302 ADT No.: 910527R02 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 30-30061.40.1631.06 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 30-30027.50.0730.230 300-1500......F/150030 1500-100,000......1.030 F = Frequency in MHz 4. 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 distance r where the MPE limit is reached. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 5. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. FCC ID: O6M-WM302 ADT No.: 910527R02 6. Test Results 6.1 Antenna Gain The maximum Gain measured in Fully Anechoic Chamber is 4 dBi or 2.51 (numeric). 6.2 Output Power Into Antenna & RF Exposure Distance : CHANNEL CHANNEL FREQUENCY (MHz) OUTPUT POWER TO ANTENNA (mW) MINIMUM ALLOWABLE DISTANCE ( r ) FROM SKIN (Centi-Meter) 1241270.633.76 6243770.633.76 11246269.023.71 The minimum allowable distance is very close to the enclosure of the antenna and is very far away from the human being under normal use condition.
