Spectrum24 Network Configuration
Use the Operating Mode pull-down menu to select one of the following options:
ESS (802.11 Station) enables the terminal to transmit and receive data with an access
point. Data rate is based on transmit retries. This is the default.
IBSS (802.11 Ad Hoc) enables terminals to form their own local network where they
can communicate peer-to-peer without access points. Use IBSS to create networks
within established cells. Terminals take turns generating beacons and handling probe
responses. The terminal starting the IBSS network (i.e., the first terminal transmitting
a beacon) sets the channel number.
If you select IBSS, the Signal tab (on the far right) turns into the Peers tab. Select Peers
to view the BSS ID or MAC address of other terminals in the network, their operating
mode (PSP or CAM), transmit rate, supported data rate, and the length of time each
terminal has been out of the IBSS network. Select Refresh to update the Peers page
to the latest network performance and membership data.
Select Pseudo IBSS (Proprietary Ad Hoc) for the highest throughput in an IBSS
network for terminal testing. Pseudo IBSS does not support PSP terminals and does
not use beacons or authentication. Select the channel for the network from the
Channel drop-down menu. Each terminal must be on the same channel. If you select
Pseudo IBSS, the Signal and Peers tabs are no longer available. Pseudo IBSS is not
recommended as a normal operational mode or for terminals operating on battery
power.
Enter a 32-character (maximum) string NIC ESS ID (802.11 Extended Service Set Identifier)
in the ESSID field to identify the wireless network. The ESS ID assigned to the terminal must
match the ESS ID of the access point.
