Key benefits

• Reduces design overhead
• Differentiated use cases by configuring WiLink™ 8 simultaneously in two roles (STA and AP) to connect directly with other Wi-Fi devices on different RF channel (Wi-Fi networks)
• Best-in-class Wi-Fi with high-performance audio and video streaming reference applications with up to 1.4× the range versus one antenna
• Different provisioning methods for in-home devices connectivity to Wi-Fi in one step
• Lowest Wi-Fi power consumption in connected idle (< 800 µA)
• Configurable wake on WLAN filters to only wake up the system
• Wi-Fi and Bluetooth single antenna coexistence

The certified WiLink™ 8 module from TI offers high throughput and extended range along with Wi-Fi^® and Bluetooth^® coexistence (WL1837MOD only) 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.
