4. Select the operating mode from the Operating Mode: drop-down list:
Infrastructure
Ad Hoc
5. Select the country of operation for the terminal from the Country: drop-down list.
This ensures the terminal is using country code information compatible with the
country code data used by the associated AP. Select International if using the
terminal with a non-Symbol AP or a pre AP-4131 model.
6. Select the Encryption tab to set the terminal profile security level.
The terminal supports Open System (no encryption), 40-bit Shared Key, 128-bit
Shared Key, Kerberos and LEAP encryption algorithms. The absence of a physical
connection makes wireless links vulnerable to information theft. Encryption is an
efficient method of preventing data theft and improving data security.
Select Infrastructure to enable the terminal to transmit and
receive data with an AP. Infrastructure is the terminal default
mode when Mobile Companion initially displays.
Select Ad Hoc to enable the terminal to form its own local
network where terminals communicate peer-to-peer without
APs using a shared ESSID. Select the Long preamble check
box if the terminal and its profile are using a long preamble
when transmitting data. A long preamble is approximately 8
bytes of the packet header attached to the packet prior to
transmission. Devices in Ad Hoc mode are required to use
the same preamble length to interoperate. The terminal
initiating the Ad Hoc network sets the channel (using the
Channel drop-down list) used by each peer in the Ad Hoc
network.
