WiLink 1835模塊天線參考設計WL1835MODCOM8B
The WiLink 1835 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 Wi-Fi and Bluetooth/Bluetooth Low Energy functionalities found on the WiLink 1835 module. This antenna design leverages the use of its certification by using the same antenna layout when the module was tested for certification, allowing customers to avoid repeated certification when creating their applications.
