O9CWL464Bridging kit - 802.11a

802.11a mini-PCI Radio Module MODEL WL-464 The 3Com 802.11a mini-PCI Radio Module Kit contains everything you need to install an additional radio and antenna into your 3Com Access Point. Kit Contents The upgrade kit contains these items: • One antenna module • One 802.11a mini-PCI Radio Module • Two cables connect the antenna module and mini PCI card by direct soldering. 1 Detach and disconnect the access point If the access point is mounted on the wall, turn the unit counterclockwise to disengage it from the mounting plate. Disconnect the Ethernet cable. Place the access point face down on a static-free surface. 2 Remove the back cover Using a cross-tip screwdriver, remove the four screws from the back cover. Remove the cover from the unit. Set the cover and screws aside. 3 Remove the antenna housing. Grasp the inside edge of the antenna housing and pull up to disengage the housing from the unit, as shown below. This part is no longer needed. 4 Install the 11a upgrade kit. 4.1. 11a mini PCI card side: Holding the radio board at an angle, align the contact edge with the mini PCI connector on the unit. Make sure the keying notch on the contact edge line up with the key on the connector, as shown in the detail below. Slide the board into the connector and press down gently until the two retainer clips snap into place. 4.2. Antenna module side: 1 Align the antenna module with the snaps and posts on the unit and press until the module snaps firmly into place. 2 Align the cables to be routed through the slots in the unit. 3 After the cables are aligned, press them down out of the way inside the housing. 5 Replace the back cover. Make sure that the cables are tucked away inside the housing so that they do not obstruct the cover. Align the back cover with the unit and settle the cover into place. Tighten the four screw. 6 Attach the antennas. Being careful not to touch the antenna tips, screw the antennas onto the SMA connectors and hand tighten them. After network startup , you may need to adjust the antennas to fine tune radio coverage. 7 Reinstall the access point. Reconnect the Ethernet cable and reattach the access point to the wall mounting plate. Adjust the antennas to improve the radio signal, if necessary. SELECTING AND CONNECTING A DIFFERENT ANTENNA MODEL The standard detachable antennas supplied with the WL-464 11a mini-PCI radio module and are suitable for a broad variety of environments. If you require a different type of antenna several options are available by model number from the 3Com Web site(www.3Com.ccom ). For each of the antenna models, you will need either a 6-foot accessory cable (model 3CWE480), a 20-foot accessory cable (model 3CWE481), or a 50-foot accessory cable (model 3CWE482) to provide the transition from the SMA connector on the access point to the N-type connector on the antenna. To ensure the physical safety of anyone near the antenna and to prevent damage to the access point, follow the building code for antenna installations in your area. Also, when connecting the optional antenna to the access point, remember to use only the A-side connector on the access point, on the right when properly installed. B-side install a terminator at the same time. 1 Position the antenna so that there are minimal obstacles between it and any client with which it will communicate. While maintaining a direct line of sight between the antenna and a client is not strictly necessary, such an arrangement helps to ensure a strong signal. Ensure that access is available for routing the antenna cable from the antenna to the access point. 2 If they are installed, remove both arms of standard detachable antenna, making sure not to handle the tips of antenna. 3 Connect one end of the optional antenna cable to the antenna and secure the antenna in place. 4 Connect the free end of the antenna cable to the right-hand side connection on the access point, as shown in the illustration above. 5 Make certain that the antennas and antenna masts are appropriately ground to prevent injury or damage from lightning strikes.

FCC ID: O9CWL464 Repport No. RF940326H02 Technical Description This device is a Bridging kit - 802.11a operates in 5GHz with OFDM technique. The transmitter rate could be 1/2/5.5/6/9/11/12/18/24/36/48/54Mbps, and the maximum data rate could be up to 108Mbps in turbo mode. The transmitter of the EUT is powered by POE (Power over Ethernet). The antenna The antennas used in this product are as below: No.ModelAntnnna Type 2.4/ 5GHz Antenna Gain Connector Type 13CWE591 (Z1996) High gain omni antenna6/ 8 dBiN Female 23CWE598 (Z1997) Medium gain panel antenna8/ 10 dBiN Female 33CWE596High gain panel antenna18/ 20 dBiN Female Under normal use condition, the user has to keep at least 20 cm separation distance between radiator and the body of the user. For more detailed instruction, please refer to the user’s manual. FCC 15.407(c) states : The device shall automatically discontinue transmission in case of either absence of information to transmit or operational failure. These provisions are not intended to preclude the transmission of control or signaling information or the use of repetitive codes used by certain digital technologies to complete frame or burst intervals. Applicants shall include in their application for equipment authorization a description of hoe this requirement is met. Data transmission is always initiated by software, which is then pass down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets (ACKs, CTS, PSPoll, etc...) are initiated by the MAC. There are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be on only while one of the aforementioned packets are being transmitted.

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. FCC ID: O9CWL464 Report No.: SA940326H022Issued: June 13, 2005 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/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 300-1500......F/15006 1500-100,000......1.030 F = Frequency in MHz FCC ID: O9CWL464 Report No.: SA940326H023Issued: June 13, 2005 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 The antenna of this product, under normal use condition, is at least 30cm away from the body of the user. Warning statement to the user for keeping at least 30cm or more separation distance with the antenna should be included in users manual.
