I really like how in depth you are going on foundational Layer 1 material so far. Example, I was so happy to see you discussing transceivers. I feel like mosts texts just give a cursory treatment to layer 1 and its hardware. I hope the next few chapters continue on with this layer 1 and hardware before moving up to Layer 2. I think it makes your book quite unique so far. Thanks for sharing.
