Introducing the M111 Client Bridge
The M111 connects legacy Ethernet or serial communications devices to a wireless local area
network (WLAN) with simplicity and security. It enables the deployment of legacy client
devices (such as electronic cash registers, servers, printers), in any location where a WLAN
signal is available, eliminating the installation of a cabling infrastructure.
In this sample deployment, the M111 provides a wireless link to a TCP/IP network for a pair
of desktop computers and a serial point-of-sale terminal. An MSM AP is used to create the
wireless network.
Key features
 Bridges an Ethernet LAN segment to a wireless network, providing connectivity for up to
20 client devices that run IPV4 and a single client device running a legacy networking
protocol, such as DECnet, IPX, or Appletalk.
 Provides an integrated serial-to-TCP/IP converter which enables a TIA-232 asynchronous
terminal device to communicate with a compatible station over a wireless network.
 802.11b a/b/g radio supporting antenna diversity.
 Provides enhanced security using configurable Ethernet MAC and bidirectional Layer 2
and Layer 3 protocol filters.
 Ensures wireless network privacy using WPA2, WPA, and WEP security and high
performance hardware-assisted AES, TKIP, WEP encryption.
 Provides 802.1X, PEAP, EAP-TLS, EAP-FAST, and EAP-TTLS authentication.
 Features a rugged, plenum-rated metal enclosure.
