Overview of the Wireless Network Module
• Configuration Order
• Wireless Equipment Placement and Range Guidelines
The wireless network module is a wireless access point that provides connectivity to multiple
wireless network devices within a fixed range or area of coverage—interacting with a
wireless network interface card (NIC) through an antenna. Typically, an individual in-building
wireless access point provides a maximum connectivity area of about a 500-foot radius. The
wireless network module can support a small group of wireless users—typically 5 to 20
users.
The wireless network module integrates a 2.4-GHz radio and a 5-GHz radio. One radio can
be active at a time to provide wireless connectivity between wired Ethernet networks and
radio-equipped wireless notebook systems, desktop systems, print servers, and other
devices. The 2.4-GHz radio supports 802.11b/g/n modes and Greenfield mode; the 5-GHz
radio supports 802.11a/n modes and Greenfield mode.
The wireless network module supports up to four wireless security profiles, allowing you to
tailor access and security to a variety of wireless clients. Each wireless security profile can
support Wi-Fi Multimedia (WMM) QoS priority and MAC address access control. The
wireless network module supports WMM Power Save and Wireless Distribution System
(WDS). You can insert one wireless network module only in the UTM9S or UTM25S.
Configuration Order

Wireless Equipment Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the location of the
UTM9S or UTM25S. The latency, data throughput performance, and notebook power
consumption of wireless adapters also vary depending on your configuration choices.
