However, without the advantage of having expertise of its own about assembling Wi-Fi modules into the cameras, Company T found itself repeatedly engaging in trial and error in its attempts to design the required boards.
The company had barely managed to fabricate prototypes that incorporated Wi-Fi modules, and it now started the verification process. However, it realized that the communication speed for some channels was extremely slow.
Since all the prototypes yielded the same results, the company carried out many checks centering on the matching of the characteristics concerning the antenna, but there were no problems with the Wi-Fi modules or with any of the other components.
After performing the verifications repeatedly, one of the engineers suspected that noise could be the problem, and the design team decided to ascertain the noise status and track down the sources of noise generation.
However, each time the verification was repeated using the evaluation apparatus and equipment that Company T had in its possession, the results were different. Even after two weeks had passed, the causes had still not been identified, and the frustration this engendered was beginning to make the engineers feel exhausted.
