To help developers easily add Wi-Fi and dual-mode Bluetooth to embedded applications for Internet of Things and industrial control, Texas Instruments (TI) has just released its WiLink 8 combo connectivity modules.
The 2.4 GHz-WL1835MODCOM8 and 5 GHz -WL1837MODCOM8, which support Wi-Fi in the 2.4 and 5 GHz bands, are designed for use in high throughput and extended industrial temperature range industrial applications (Table 1 below ).

They are configured for use in power-optimized designs for home and building automation, smart energy, gateways, wireless audio, enterprise, wearables and many more industrial and Internet of Things (IoT) applications.
The WiLink 8 modules and software are compatible and pre-integrated with many processors including TI's ARM based Sitara processors. According to Amichai Ron, general manager, Wireless Connectivity Solutions, TI, Wi-Fi and Bluetooth software stacks and sample applications are provided, and the modules are FCC/IC/ETSI certified.
Designed to operate over the extended temperature range of -40C to 85C required for industrial applications, the 5 GHz modules are designed also to take advantage of the less noisy frequency band.
Developers of smart energy and home gateways which offer Wi-Fi, Bluetooth and ZigBee coexistence can use the modules to manage multiple devices through Wi-Fi multi-channel multi-role (MCMR) capabilities.
They are optimized for low power applications with low idle connect current consumption and can handle 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.
