Wireless module n parade at Embedded World

The module can be easily connected to a host controller by means of SDIO interface. In addition to a Bluetooth interface, a UART interface is available for Bluetooth operation. Furthermore, a two-wire serial interface (TWSI) is included on the module for near field communication (NFC). Audio applications benefit from the integrated pulse code modulation (PCM) and inter-IC sound (I2S) functions.

Through the 1x1 antenna configuration, PHY data transfer rates up to 433 Mbps and transfer rates up to 3 Mbps via Bluetooth are feasible. The possibility of 64-bit or 128-bit AES hardware encryption and integrated security mechanisms such as 64/128-bit WEP, WPA, WPA2 and WAPI ensure a high level of data security.

With an output power up to +18 dBm in 802.11b mode and +15 dBm in 802.11a/g/n mode or up to +8 dBm with Bluetooth operation, the wireless interfaces are also especially powerful. Coexistence functions are supported by an internal TDM unit for WLAN and Bluetooth as well as a 2-wire UART for LTE.

A Linux driver is offered for software support. Other platforms will follow afterwards. In addition to WLAN station mode with infrastructure and ad-hoc mode, a WLAN µAccess Point with up to 10 clients and Bluetooth is contained in the firmware. The new data transmission standard Wi‑Fi Direct is also already supported by the system.

The WiBear11ac automotive-grade wireless module is radio type approved for Europe (CE), the United States (FCC) and Industry Canada (IC), and meets automotive qualification tests (climatic, mechanical, and operating life tests) according to VW 80000 / ISO 16750-4. The operating temperature range of the module is from -40°C to +85°C.

MSC provides developers with an extensively equipped evaluation board and optional accessories for getting started quickly.
