Introduction
Thanks for purchasing Radicom Research’s SMD WiFi Module. Radicom is committed to providing quality service and technical support in order to expedite the product development process. The WiFiHU2S Module is designed to fully support
IEEE802.11n™ Draft 2.0, IEEE802.11e™ and IEEE802.11i™ standards. If further
information is required, please contact us and we will provide any additional help needed. The WiFiHU2S series offers SoftAP support. It can turn your Internet connected PC or Laptop into a WiFi Wireless Access Point. So any WiFi device such as iPhone, iPod, PDA, within range can connect to Internet by sharing your WiFiHU2S Access Point. The WiFiHU2S-a/c requires significant CPU power to run in SoftAP mode on
802.11n. Unless you have a very powerful CPU, it is recommended to use the SoftAP mode of WiFiHU2S in 802.11b or g modes only.

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.
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. Can use one or two cables and antennas
AC6i-RP-SMA
ATN-2d-RP-SMA
*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.
6" U.FL. to RP-SMA female connector antenna cable
Replacement antenna, 2.4GHz, 2dBi, RP-SMA, Omni­directional.

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. 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.
For ultimate performance, we recommend using two antennas to get

General 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.
