The chapter introduces and explains the 21XX access points and how you can use
them in a data collection network.
Overview of the MobileLAN access 21XX Family
Intermec’s MobileLANaccess 21XX family of access points delivers reliable and
seamless wireless performance to almost any operational environment. They are
designed for standards-based connectivity and they support industry standard IEEE
802.11b, WLI Forum OpenAir, and IEEE 802.11a wireless technologies.
™
The 2100, 2101, or 2102/2102S with an IEEE 802.11b radio installed is Wi-Fi certified
for interoperability with other 802.11b wireless LAN devices.
The 21XX family consists of these access points:
•2101
•2100
•2102/2102S
•2106
The access point can be configured as an access point or as a point-to-point bridge. An
access point is connected to a wired local area network (LAN) and provides network
access for wireless end devices. A point-to-point bridge connects two wired LANs and
is often used to provide wireless communications in locations where running cable is
difficult, such as across roads or between buildings.
The access point can also be configured as a wireless access point (WAP) or repeater. A
WAP is not connected to a wired LAN; it receives data from wireless end devices and
forwards the data to an access point (that is connected to the wired LAN). A WAP is
useful in areas that do not support a wired network connection.
Note: For help with your 2102S (Simplified) access point, see the MobileLAN
