LS Research TiWi-R2 Integrated Transceiver Module

LS Research TiWi-R2 Integrated Transceiver Module is a high performance 2.4GHz IEEE 802.11 b/g/n Bluetooth 2.1+EDR radio in a cost effective, pre-certified footprint. LS Research TiWi-R2 Integrated Transceiver Module has the necessary PHY/MAC layers to support WLAN applications along with a host processor over a SDIO interface. The module also provides a Bluetooth platform through the HCI transport layer. Both WLAN and Bluetooth share the same antenna port.

LS Research has expanded its line of TiWi Integrated Transceiver Modules to include the TiWi-BLE, a high performance 2.4GHz IEEE 802.11 b/g/n Bluetooth 2.1+EDR and Bluetooth Low Energy (BLE) 4.0 radio in a cost effective, pre-certified footprint. This module is similar to the TiWi-R2, but has the additional BLE functionality. The TiWi-BLE has a compact design based on the Texas Instruments WL1271L Transceiver.
