If you are new to the field & want to get that experience, setting up a home lab is the most important. Home lab is essential if you want to keep learning
I played and tested! You have to be interested enough to invest the time to get the knowledge and experience.
Here's a webinar we did last year on building a home lab: https://www.youtube.com/watch?v=zNCIlNsDq88&list=UU4_fdLXjHf_Kd_PXKD3MxHw
And here is one on 802.11ac protocol analysis that references some low cost gear: https://www.youtube.com/watch?v=ZXD_qg5dddM&list=UU4_fdLXjHf_Kd_PXKD3MxHw
My personal favorite is MetaGeek WiSpy. MetaGeek also has some great free training videos about spectrum analysis.
