CHAPTER 3 WIRELESS APPLICATIONS
Introduction
Wireless Local Area Networks (WLANs) allow the MC18 mobile computers to communicate wirelessly and
send captured data to a host device in real time. The MC18 supports the 802.11a, 802.11b, 802.11g and
802.11n standards. Before using the MC18 on a WLAN, the facility must be set up with the required hardware
to run the wireless LAN and the MC18 must be configured. Refer to the documentation provided with the
access points (APs) for instructions on setting up the hardware.
To configure the radio in the MC18, use the Fusion APIs in the Enterprise Mobility Developer’s Kit (EMDK).
Refer to the EMDK Help file for detailed information.
The MC18 contain the Wireless Applications to allow configuration of the WLAN radio. On the MC18, use the
touch screen to access the Wireless Application. MC18 requires the use of remote control software. See
Chapter 4, Sync with Host Computer for more information.
802.11d Overview
IEEE 802.11d, is an amendment to the IEEE 802.11 specification that adds support for additional regulatory
domains. This includes additional country information to beacons, probe requests, and probe responses. The
country information simplifies the creation of 802.11 wireless access points (APs) and clients that meet the
different regulations enforced in various parts of the world.
Fusion fully supports 802.11d for Regulatory purposes. By using 802.11d, the MC18 can easily connect to a
wireless network and use only the valid channels for the country specified in the AP's beacons. By default, the
MC18 software enables 802.11d mode to determine regulatory requirements.
Configuring My Country for Use with WLAN on the MC18
Configuration can be done on:
• an enabled 802.11d network
• a disabled 802.11d network.
