3.12.3 WLAN SETTING
Wireless networking can operate in two modes – (1) Ad-hoc mode: peer-to-peer, and (2)
Infrastructure mode: point to multi-point through access points.
Set the following parameters.
Local Name
Enter a name for identifying the Terminal.
 By default, it is made up of model number and the serial number.
SS ID
This refers to Service Set Identifier or AP name, which is used for remote device association.
 The Terminal can ONLY communicate with access points that have the same SS ID.
Roaming Setting
This refers to Access Point Density.
System Scale options — [1] Low [2] Medium [3] High [4] Custom –Tx Rate [5] Custom -Rssi
 The value you set must match that set for the access point.
 “Low / Medium / High” means the Terminal will search for other APs only when data
transmission rate drops below “1 / 2 / 5” Mbps individually.
 “Custom –Tx Rate” lets you set data rate for the Terminal to search for other APs when data
transmission rate drops below the specified value —
802.11b: 1, 2, 5.5, 11 Mbps
802.11g: 1, 2, 5.5, 11 Mbps & 6, 9, 12, 18, 24, 36, 48, 54 Mbps
 “Custom –Rssi” lets you set the conditions for the Terminal to search for other APs —
RSSI Threshold: options including -50, -55, -60, …, -85, -90 dBm. When the current AP signal
strength (RSSI) goes below the specified value, the Terminal starts to search for other APs.
RSSI Delta: options including 0, 5, 10, 15, and 20. Compare the signal strength between the
current AP and the new one. If the signal differential between them is equal to or higher than
the specified value, the Terminal will connect to the new AP.
Roaming Period options — 3 ~ 10 seconds
