Wireless Networker LA-5030 PC Card & LA-5033 PCI Adapter User Guide 5
Note: To comply with FCC and Industry Canada exposure
requirements, this hand-held device is approved for operation
near a user’s hand when there is 20 cm or more between the
antenna and the user’s body.
2.2 Operating Modes
The Symbol Wireless Networker a/g Adapter Configuration Utility installs
with the Windows driver. Use the Configuration Utility to select the
operational mode, ESSID, encryption algorithm, authentication scheme
and power consumption mode used with the LA-5030 PC Card or LA-
5033 PCI adapter.
The LA-5033 PCI adapter and LA -5030 PC Card support the following
operational modes:
• Use Infrastructure to operate with an access point (AP). The
adapter can roam freely between AP cells in the network or transmit
and receive across subnets. Mobile Units (MUs) appear as network
nodes to other devices in the network. Infrastructure is the adapter
default mode.
• Select Ad Hoc to form peer-to-peer LA-5030 networks without APs.
Use Ad Hoc to create networks within established network coverage
areas or networks free of the constraints of access point provided
radio coverage. The MU starting the Ad Hoc network (the first
LA5030 adapter transmitting a beacon) determines the channel and
data rate used for the other LA-5030 adapters within the network
using the same ESSID.
The Symbol Ad Hoc mode is an Independent Basic Service Set
(IBSS) mode requiring no backbone infrastructure. The lack of an
access point results in MUs alternating the duty of sending beacons.
There are no relay functions in an Ad Hoc (IBSS) network, not every
MU is capable of communicating with other MUs due to the range
