Dual-pane windows interfering with cell signal?
Nerdy, techie post below:
I'm a reasonably technical guy, and I was curious as to what degree (a) the heated windshield and/or (b) the dual-pane / acoustic glass of C217 S coupes interfered with typical US cell signal strength and download throughput.
In brief comparisons while parked, I noticed a several-point RSRP improvement, and ~30-40 / ~5-10 Mbps down/up improvement, in simply having my driver's side window down, involving bands 12-13 (700 MHz range) on the same device in this case.
There is aftermarket ceramic, non-metallic, tint on the glass.
I would have thought the windshield would have been more problematic, and the side windows much less an issue.
This makes me wonder: is it something about acoustic lamination I presume is present? Something about the dual-pane structure of the glass?
Unfortunately, there is no wireless coupling to an external antenna available in my 2016.
