MonoMonday: "Response to...Infrastructure"

Picturemull's MM challenge this week is a response to her blip here. I thought of her blip as an example of infrastructure, so I took this shot of mobile phone masts. The larger, main one in the photo has only recently appeared so I assume it's to serve 5G - I'm guessing that the older, smaller one next to it is for 4G - but if anyone knows better than this I'd be interested to know.

I guess I can fiddle an additional response - Picturemull's photo showed a highway, whereas my photo is part of the information highway. So a double whammy :-)
