Wireless Networking
Wireless technology allows the TANDBERG FieldView Device to be used
in places where accessibility would otherwise be difficult. The TANDBERG
FieldView Device has been optimized for reliable, high quality streaming media
within a wireless environment. This allows the TANDBERG FieldView Device to
remain connected in a streaming session while roaming between access points
over a wide coverage area.
Wireless connectivity on the TANDBERG FieldView Device is provided by an
IEEE 802.11b/g Wireless Local Area Network (WLAN) interface. The WLAN
interface is capable of up to 54 Mbps throughput when operated on an 802.11g
network and 11 Mbps when operated on an 802.11b network.

as used with the FieldView. For specific information (installation,
configuration, etc.) consult your vendor’s documentation.
Wireless configuration and optimization for the workstation (e.g. a laptop

computer) that is used to host the TANDBERG FieldView Application is
beyond the scope of this document. Consult the appropriate documentation
and support channels for the workstation.
This discussion relates to the operation of the TANDBERG FieldView Device

in a wireless mode. Similar considerations exist for operation of a wireless
workstation that acts as host for the TANDBERG FieldView Application.
Many of the topics covered in this section are relevant for the workstation
as well as the TANDBERG FieldView Device; however the performance
and characteristics of wireless networking equipment vary widely. For best
results, the workstation should be connected to a wired network connection
whenever practical.
Although using a wired network connection with the workstation is strongly
•
recommended, some wireless workstations will function adequately as long
as sufficient signal quality is available and roaming of the workstation is not
required.
Overview
It is beyond the scope of this document to completely cover all aspects of
wireless networking. However, the following sections provide an overview
of some of the key concepts that relate to the use of voice and video over a
wireless network including the following topics:
Radio Frequency (RF) channel selection
•
Interference
•
Coverage
•
Roaming
•
Site survey
•
Perspective—Is all this really necessary?
The guidelines in the following sections assure the best possible performance
and quality. However, not every organization will have the means or desire to
ensure that all of the recommended steps are taken. In many cases, a less
rigorous approach may allow acceptable performance as long as the limitations
are understood.
A simple setup (such as connecting to existing infrastructure as-is) will
