1. INTRODUCTION
The CM9 Wireless Local Area Network (WLAN) module supports the IEEE 802.11a/b/g specification. It
uses the standard mini-PCI interface as the digital port and a special U.FL connector as the RF port.
The CM9 WLAN mini-PCI Module provides a wireless networking function. The dual-band wireless
802.11a/b/g mini-PCI bus adapter operates seamlessly and simultaneously in both the 2.4GHz and 5GHz
frequency spectrums supporting the 802.11b (2.4GHz, 11Mbps) and the newer, faster 802.11a (5.8GHz,
54Mbps/108Mbps turbo mode) and 802.11g (2.4GHz, 54Mbps) wireless standards. It is the best way to
add wireless capability to an existing wired network, or to add bandwidth to a wireless installation.
To protect wireless connectivity, the dual-band wireless 802.11a/b/g mini-PCI bus adapter can encrypt all
wireless transmissions through 64/128/152-bit WEP data encryption. Dynamic Frequency Selection (DFS)
puts the network on the cleanest channel in a given location.
1.1. Features
• High-Speed data transfer rate up to 108Mbps

1.2. Basic System Requirements
• A computer system that supports the mini- PCI platform and contains:
•
32MB of memory, or greater
• 200MHz processor, or higher
1.3. RF Connection
The CM9 WLAN module uses 50 ohm impedance U.FL connectors with maximum RF power of 18dbm. It
has two RF connectors for the two RF ports (primary and secondary). The two RF ports provided an
antenna diversity feature such that only the port with the best receiving signal quality will be used
dynamically. The two ports support both 802.11b and 802.11g in the 2.4GHZ band, and 802.11a in the
5.8GHZ band with a software switch. See Figure A for details.

HARDWARE INSTALLATION & ANTENNA INFORMATION
The FCC ID for the CM9 module when combined with proven high gain antennas shall be used only for the
3eTI outdoor WLAN access point or bridge applications. The module is not allowed to be sold to any retail
party or to any OEM party. Due to FCC frequency restrictions and to the requirement of the high gain
antennas for indoor and outdoor applications, the 5.15GHZ to 5.25GHZ indoor frequency band is disabled
in 3eTI outdoor products.
Figure C shows an example of the outdoor bridge 3e-523. Figure D is the open case view of the 3e-523 :
The 3e-523 Processor PCBA loaded with the CM9 module is mounted in the outdoor enclosure.
