• Antenna ID selects the antenna to be used by the access point; either the integrated diversity
antennas (the default antenna) or an optional external antenna. The optional external antennas
(if any) that are certified for use with the access point are listed in the drop‐down menu.
Selecting the correct antenna ID ensures that the access point's radio transmissions are within
regulatory power limits for the country of operation. When an external antenna is selected, the
Antenna Control Method must be set to Right. Default: Default Antenna

• Turbo Mode (802.11a ONLY) is the normal 802.11a wireless operation mode provides
connections up to 54 Mbps. Turbo Mode is an enhanced mode (not regulated in IEEE 802.11a)
that provides a higher data rate of up to 108 Mbps. Enabling Turbo Mode allows the RBT‐4102
to provide connections up to 108 Mbps. Default: Disabled
4-58 Advanced Configuration
Right. The radio only uses the antenna on the right side (the side closest to the access point
LEDs). Select this method when using an optional external antenna that is connected to
the right antenna connector.
Left. The radio only uses the antenna on the left side (the side farthest from the access
point LEDs). The access point does not support an external antenna connection on its left
antenna. Therefore, this method is not valid for the access point.
Note: The Antenna ID must be selected in conjunction with the Antenna Control Method to
configure proper use of any of the antenna options.

Note: The RBT-4102-EU has been approved for use with these external antennas. Some
countries restrict or require a license when using outdoor antennas. Please refer to the
conditions of use located in the front of the RoamAbout Wireless RBT-4102 Installation Guide.

Note: In normal mode, the access point provides a channel bandwidth of 20 MHz, and supports the
maximum number of channels permitted by local regulations (e.g., 13 channels for the United
States). In Turbo Mode, the channel bandwidth is increased to 40 MHz to support the increased data
rate. However, this reduces the number of channels supported (e.g., 5 channels for the United
States).
