■ Notes on Use of Roaming Function

◎ The roaming function is enabled in the Access Point mode and, therefore, this function
cannot be used in the Building Communication mode.
◎ Any terminal connected to SB-110 by wireless must be equipped with our 11 Mbps
wireless LAN card.
◎ In the radio transmission area where a wireless terminal moves around, [ESS ID] (
see 5-1) and [WEP] ( see 5-2) of the wireless terminal must be the same as those of
SB-110 used in the roaming function. If [ESS ID] or [WEP] specified in the wireless
terminal is different from that of SB-110, any communication to such wireless terminal is
unavailable.
◎ Any wireless LAN terminal operates as a network group which is the same as that of
wired LAN terminal, including the roaming area. Therefore, do not used the roaming
function together with the Routing mode ( see 5-3).
Otherwise, the communication becomes unavailable due to invalid network address.
◎ To avoid radio interference, when any channel is changed, keep a sufficient distance
equivalent to four channels or more between the channel to be changed and the other
party's radio access point channel. Otherwise, as shown below, the radio interference
may occur because a part of frequency bands overlap each other. For example, if
Channel 1, Channel 6 and Channel 11 are specified, no radio interference occurs.
