2 Introduction
The IEEE 802.11abgn OEM Modules from connectBlue has been developed for integration in industrial devices. The modules are
providing state of the art low power features, compatibility, robustness, and reliability. The modules minimizes the work needed to
implement IEEE 802.11 in a device as it provides, together with the driver package, all software, hardware, type approval, EMC
certification etc. It is developed for reliable, high demanding industrial devices and applications and delivers high performance. The
connectBlue wireless LAN modules are available in different versions (see Product variants).
The wireless LAN modules are complete IEEE 802.11 implementations. The IEEE 802.11 modules has small form factors and the
interface layout is the same as the Bluetooth and IEEE 802.15.4 modules from connectBlue, which enables customers to prepare their
device for both wireless LAN, IEEE 802.15.4, and Bluetooth.
2.1 Key features
Dual-band operation (IEEE 802.11-2007, abg, incl. single stream IEEE 802.11n)
WEP, AES, and CRC-32 hardware accelerators
WPA and WPA2 support - both personal and enterprise modes
UART host interface
SPI host interface
Quality of Service: 802.11e and WMM
Ad-hoc and infrastructure mode
