2.4 and 5 GHz Wi-Fi and Bluetooth combo modules for industrial applications

November 07, 2014 // By Graham Prophet
Texas Instruments’ WiLink 8 family is intended to make development easier and faster with pre-certified modules and a complete software offering

TI's WiLink 8 combo connectivity modules support Wi-Fi in the 2.4 and 5 GHz bands, and provide high throughput and extended industrial temperature range with Wi-Fi + Bluetooth coexistence. WiLink 8 modules are suitable for power-optimised designs for home and building automation, smart energy, gateways, wireless audio, enterprise, wearables, industrial and IoT applications. The WiLink 8 modules and software are compatible and pre-integrated with many processors including TI’s Sitara processors. TI says the modules requires less hardware and RF design experience; Wi-Fi and Bluetooth software stacks and sample applications are provided, and the modules are FCC/IC/ETSI certified.

With 2.4 and 5 GHz versions that are pin-to-pin compatible, and offer;

- Extended temperature range of -40 to 85C for industrial applications

- 5 GHz module which enables customers to build high performance solutions by taking advantage of the less noisy frequency band

- Smart energy and home gateways, with Wi-Fi, Bluetooth and ZigBee coexistence, can be managed using multiple devices through Wi-Fi multi-channel multi-role (MCMR) capabilities

- 1.4x the range and up to 100 Mbps throughput with TI’s WiLink 8 MRC (maximal ratio combining) and MIMO (multiple-input and multiple-output) technology

- Optimisation for low power applications with low idle connect current consumption

- Audio streaming for home entertainment applications with both Wi-Fi and dual-mode Bluetooth/Bluetooth low energy

The WiLink 8 modules complement several TI platforms to deliver system solutions for manufacturers including WiLink 8 module-based evaluation boards (2.4 GHz-WL1835MODCOM8 and 5 GHz -WL1837MODCOM8) that are compatible with the AM335x EVM and AM437x EVM.
