2.4 & 5 GHz Dual Band Wi-Fi® + Bluetooth® Certified Antenna Design on WiLink™ 1837 Module
The WL1837MODCOM8I is a Wi-Fi® dual-band, Bluetooth, and BLE module evaluation board (EVB) with the TI WL1837 module (WL1837MOD). The WL1837MOD is a certified WiLink™ 8 module from TI that offers high throughput and extended range along with Wi-Fi and Bluetooth coexistence in a poweroptimized design. The WL1837MOD offers A 2.4- and 5-GHz module solution with two antennas supporting industrial temperature grade. The module 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®, Android™, WinCE, and RTOS.TI.
The WiLink 1837 module antenna design is a reference design that combines the functionalities of the WiLink 8 module with a built-in antenna on a single board, implementing the module in the way it’s been certified. Through this, customers are able to evaluate the performance of the module through embedded applications such as home automation and the Internet of Things that make use of both embedded Wi-Fi and Bluetooth / Bluetooth low energy functionalities found on the WiLink 1837 module. This antenna design leverages the use of its certification by using the same layout when the module was tested for certification, allowing customers to avoid repeated certification when creating their applications.
