5 Model and Ordering Information This versatile WiFiHU2S family of products offers configuration options to meet the specific system. The WiFiHU2S is available as a SMD module with antennas interface. The WiFiHU2S also has many different antennas options. *These models can use either one or two cables and antennas. For ultimate performance, we recommend using two antennas with better adaptability for receiving. If user want to use only one set of cable and Antenna, try to use CON1 first. Model Description Comments WiFiHU2S-a WiFi SMD Module with dual on board chip antennas Uses onboard chip antennas. Not for use with External Antenna. WiFiHU2S-c * WiFi SMD Module with dual on board U.FL connectors for attaching antenna cables and 2.4GHz 2 dBi Omni-directional antennas Allows designer to determine antenna placement.

Antenna for model WiFiHU2S-c
6 Connecting the WiFiHU2S to Your System Prior to connecting the WiFiHU2S to a Window XP, the drivers should be installed. The WiFiHU2S Modules are designed for easy connection to any wireless network. If using Windows, load the provided drivers. The WiFiHU2S is now ready for use. If you plan to embed the WiFiHU2S into your system, the SMD type can be mounted onto your main board to verify or test the module functions. If you use external antenna, connect one end of Radicom approved antenna to the on board U.FL connector. For ultimate performance, we recommend using two antennas to get exceptional reception and throughput. If only using one antenna, you must use the correct antenna socket for good performance. Connect single antenna to the socket closest to the Radicom Research white silkscreen legend on the PCB.
7General Layout Design Suggestions • General Layout Rules- All Printed Circuit Boards must comply with UL94V0 standard for flammability. Always use RoHS compliant Parts and materials. • Suggestions for Layout: 1. Do not place Power circuit, X’tal, Inductor, etc near RF area. 2. The bigger Antenna clearance area, the better. The Antenna circuitry needs to stay away from any circuit or component by at least 2mm. For best operation, Antenna clearance area means Top and Bottom both required to be cleared. 3. Do not use metal materials near Antenna area. For example, battery snaps, USB connector, iron case, etc. Note: These guidelines are for design reference; real performance still depends on the actual design.

12 FCC, IC, and CE Label Location and Module Model Identification (PENDING) The WiFiHU2S module family is FCC Part 15 and IC (Industry Canada) certified. The WiFiHU2S is also CE marked. The modules are labeled with the appropriate WiFiHU2S module model number and FCC Part 15 ID, IC registration number and CE mark. The label can be found on top of the metal shielding on the WiFiHU2S Module. Important Regulatory Compliance and User Information The final product with the modules installed needs to be tested for FCC Part 15, IC (Industry Canada) CE, EMI/RFI compliance. Radicom certification documentation will help streamline the final product approval process. Contact Radicom for more information. To maintain compliance in the finished product, carefully follow guidelines in this section. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users. For laptop installations, the antenna must be installed to ensure that the proper spacing is maintained in the event the users places the device in their lap during use. 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as the two conditions above are met, further transmitter testing will not Radicom Research Inc. Model: WiFiHU2S-c FCC ID: K7T- WIFIHU2 IC: 2377A- WIFIHU2 Radicom Research Inc.

13be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with the module installed (for example, digital device emissions, PC peripheral requirements, etc). IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Host (End Product) Labeling Requirements To maintain compliance, the end product hosting the WiFiHU2S module must be properly labeled to identify that this module is installed. This transmitter module is authorized only when used in devices where the antenna is installed such that 20 cm is maintained between the antenna and users. The final end product must have a label located in a visible area with the following information: The XXXXXXX reflects the correct model installed into the host equipment: The models are WiFiHU2-a, WiFiHU2-c, WiFiHU2-a-1-NE, or WiFiHU2-c-1-NE The label shall be securely affixed to a permanently attached part of the device, in a location where it is visible or easily accessible to the user, and shall not be readily detachable. The label shall be sufficiently durable to remain fully legible and intact on the device in all normal conditions of use throughout the device’s expected lifetime. These requirements may be met either by a separate label or nameplate permanently attached to the device or by permanently imprinting or impressing the label directly onto the device. The label text shall be legible without the aid of magnification, but is not required to be larger than 8-point font size. End User Information: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF Exposure compliance. The end user should NOT be provided any instructions on how to remove or install the device. The users manual for end users must include the following information in a prominent location. Contains Transmitter Module Model: XXXXXXX FCC ID: K7T- WIFIHU2 IC: 2377A- WIFIHU2
