The following product brief applies to LS Research’s
WLAN + Bluetooth module, series name: TiWi. The
WLAN + Bluetooth chip used is the WL1271 from
Texas Instruments.
The WL1271-TiWi is a fully-integrated high
performance module offered by LS Research using
TI’s single-chip WL1271 2.4GHz IEEE 802.11 b/g/n
and Bluetooth v2.1 + Enhanced Data Rate (EDR)
Transceiver. Based on TI’s 6th generation WLAN
technology and 7th generation Bluetooth technology,
the solution provides best-in-class coexistence
capabilities coupled with TI’s Enhanced Low Power
(ELP) technology. The WL1271-TiWi is provided as a
module to help customers reduce development time,
lower manufacturing costs, save board space, ease
certification, and minimize RF expertise required. For
evaluation and development, various platforms are
available which integrate the WL1271-TiWi module,
Linux WLAN drivers, BlueZ Bluetooth stack, and
sample source applications running on a TI host
processor (AM/DM37x, AM18x, OMAP4).
The full specification and purchasing of the
WL1271-TiWi module can be found on LSR's website
(www.lsr.com/tiwi). More information on TI’s wireless
platform solutions can be found on the Wireless
Connectivity Wiki (www.ti.com/connectivitywiki).
