Consumer Electronics Case Study: Wireless Hubs’ Electromagnetic Interference

Wireless hubs are designed to transmit information quickly through 3G/4G towers, or even though Wi-Fi. But with all of this information spreading, there’s a chance for electromagnetic interference (EMI), or a disturbance in an electronic device’s operation. To achieve EMI shielding, one customer was sending the molded parts they’d manufactured…
