1.5.1 Dual Band Router Mode
In Dual Band Concurrent mode, the radio1 works in 5Ghz while radio2 works in 2.4GHz
mode. That means the A.DUO can provide Internet service to both 5GHz (like game
network) and 2.4GHz (like PC network) at the same time.

1. Introduction
AirLive A.DUO User’s Manual 4
1.5.2 Dual AP Mode
In Dual AP mode, both wireless interface of A.DUO are set as AP and provide hotspot
service on each interface. Radio1 is set to 11a mode while Radio2 is set to 11g/b Mode
(changeable to 11a also). This mode is most useful for Dual Band Hotspot function such
as in the hotels, shopping malls, or offices.

1. Introduction
5 AirLive A.DUO User’s Manual
1.5.3 WISP + AP Mode
In this mode, Radio1 (in 11a mode) acts as a client to connect with remote WISP Base
Station. Radio2 (in 11g/b mode) works as an AP router to allow subscriber to share the
WISP connection wirelessly. Using the A.DUO, WISP no longer requires 2 AP/CPE to
provide wireless access in subscriber’s home or office.
1.5.4 Bridge + AP Mode
In this mode, Radio1 is working as Bridge mode in 5GHz while Radio is working as AP
mode in 2.4Ghz or 5GHz (selectable0). This mode is useful for WISP backbone
application where Radio 1 is used for connection to another Base Station and Radio2 is
used for service to subscribers. This mode can also be used as repeater in indoor
environment.

1. Introduction
AirLive A.DUO User’s Manual 6
The A.DUO’s Bridge mode can be configured as “WDS Bridge” or “Bridge Infrastructure”.
In WDS Bridge, you must enter the remote AP’s MACAddress. It can connect with
another WDS Bridge.
In Bridge Infrastructure, you do not need to enter remote AP’s MAC address. It work
like a client mode with MAC address transparency. Please note that this bridge type
can only connect with Access Point. It can not connect with another Bridge.
1.5.5 Dual Bridge Mode
In Dual WDS Bridge mode, both wireless interface of A.DUO are set as WDS Bridge and
connect to remote network. This mode can be used to extend the distance of remote
Bridge connection.

1.5.7 Bridge + Gateway
In this mode, the radio1 is configured as a 5GHz Bridge while Radio2 is configured as AP
Router in 11a/b/g mode. This mode is useful if your remote Base Station is working in
WDS Bridge mode to transmit Internet broadband.
The A.DUO’s Bridge mode can be configured as “WDS Bridge” or “Bridge Infrastructure”.
In WDS Bridge, you must enter the remote AP’s MACAddress. It can connect with
