1.1 TI WL1837MOD

The certified WiLink 8 module from TI offers high throughput and extended range along with Wi-Fi and Bluetooth coexistence in a power-optimized design. The WL18x7MOD is a Wi-Fi, dual-band, 2.4- and 5-GHz module solution with two antennas supporting industrial temperature grade. The device is FCC, IC, ETSI/CE, and TELEC certified for AP (with DFS support) and client. TI offers drivers for high-level operating systems, such as Linux® and Android™. Additional drivers, such as WinCE and RTOS, which includes QNX, Nucleus, ThreadX, and FreeRTOS, are supported through third parties. The TI WL1837MOD offers a unique feature of time synchronization using AP beacons that are used to achieve ultraprecise Audio Multiroom/Speaker synchronization.
