Manual Change Record

This page records the changes to this manual. The manual was originally released as version 001.

Version Date Description of Change

002 11/1998 Added information about the 900 MHz UAP and WAP, and the OpenAir WAP.

003 6/1999 Added information about the IEEE 802.11 Direct Sequence radio and firmware

upgrade features.

004 10/1999 Added information about the S-UHF radio and the 2101 Universal Office Access

Point. This revision also reflects the discontinuance of the 2110 Wireless Access

Point and the name change for this manual from a user’s manual to a technical

reference manual.

005 12/1999 Revised IEEE 802.11 DS radio menus and parameters.

006 10/2000 Revised to support firmware v1.4. Features include the addition of the IEEE 802.11b

007 02/2001 Reorganized and revised to support firmware 1.50. Features include the ability to use

the access point as a DHCP server, improved access control, and internet software

download support.

008 03/2002 Reorganized and revised to support firmware 1.7x and the 2106 access point with the

802.11a radio. This revision also reflects the name change for this manual from a

technical reference manual to the MobileLAN access 21XX System Manual.

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
