Cisco Radio 161
E-EQ-VX5RG-G-ARC VX5 Reference Guide
Figure 4-46 Cisco Properties – RF Network
The RF Network Tab allows you to set:
• Data Rate – The higher the transmit rate, the greater the throughput, but the range is
decreased. Auto Rate Selection uses the highest transmit rate whenever possible, but
uses the slower rates as necessary. Auto Rate Select is the default.
• Use Short Radio Headers – Selecting this checkbox allows the adapter to use short
radio headers. If any clients associated with an access point are using long headers,
then all clients must use long headers even when this box is checked. Short radio
headers improve throughput performance. Long radio headers ensure compatibility
with clients and access points that do not support short headers. The default is to use
short radio headers.
• World Mode – Selecting this checkbox enables the adapter to adopt the maximum
power level and frequency range of the access point to which it is associated
(provided the Access Point is configured for World Mode). This parameter is
available only in Infrastructure mode. The default is disabled.
• Scan For A Better Access Point – When selected, if the associated Access Point’s
signal becomes low, this option allows the adapter to search for a better Access Point
and switch to that Access Point. The default is selected. The time period of
association before scanning and the signal strength can be configured. LXE
recommends 10 seconds for the association time before scanning and 40% for the
signal strength.
• Channel – The default is 6. The channel selected must match the Access Point
(Infrastructure mode) or the other computers (Ad Hoc mode).
• Transmit Power – The default is 100 mW. Higher transmit power drains batteries
faster.
• Data Retries – The number of times a packet is to be resent if the transmission is
not successful. The default is 16.
