I have found that our main purpose is to help the end users, perform their work in an easier way. This could be; helping a nurse providing care, a banker moving money around, a school teacher sharing knowledge, a journalist reporting news, a warehouse worker moving goods or even sport fans supporting their team.
The end users will be the ones using the Wi-Fi, enjoying the Wi-Fi, taking advantage of the Wi-Fi and maybe sometimes cursing the Wi-Fi. They are the reason why we do what we do. This is why, as a Wi-Fi Engineer, I always try to keep them in mind while designing, installing and troubleshooting a Wi-Fi network.
Focusing on the end user experience helps me to put the human factor back into the game. I consider it a very important part of my work.
