ESCRIPTION
The Laird WB45NBT provides complete enterprise-class Wi-Fi connectivity with an
integrated TCP/IP stack, full support for IEEE 802.11a/b/g/n and Bluetooth 4.0
dual-mode air standards, and a fully integrated security supplicant providing
802.11i/WPA2 Enterprise authentication, data encryption, and BT protocol stacks.
The WB45NBT is a fully integrated module with RF shielding and two U.FL type
antenna connectors. The Main antenna (for Wi-Fi) and the Auxiliary antenna (for
Bluetooth) work separately to get the best coexistence performance. Although not
currently supported, the third antenna connector multiplexes both the Wi-Fi and
Bluetooth signals into a single RF port through the use of a T/R switch.
Note: For additional information on the hardware aspects of the WB45NBT,
please refer to the
Hardware Integration Guide download on the
WB45NBT Product Page .
