To save production costs, simplify software development, accelerate certification cycles, and achieve faster time-to-market, many internet of things (IoT) devices resort to using a module-based design. However, a device involving multiple wireless modules may suffer from antenna/radio frequency issues that can result in failing to obtain standard system certification (TRP/TIS/EMC/EMI). At wSDL we develop hands on practical solutions to real-world engineering challenges.
