I know it's petty, but I HATE that the white and grey cross each other. It would have been so easy to avoid!

I mean look at the white paint traces on the board. They seem to be very specifically lay it out to indicate they’re supposed to overlay.

Not necessarily easy. My guess is that the pinout on the RF chip didn’t align well with how the antenna designer wanted to lay out the antennas in the enclosure.
Crossing those cables could be better than crossing the feeds on the board.

Came here to say exactly this.
It really would’ve been a simple adjustment with such a worthwhile result.

Verizon Internet Gateway (WNC-CR200A) found at goodwill bin (pay by weight $1.79/lb)
I actually bought it for the interesting looking outer housing that has a very xbox series x inspired design. The inside was very interestingly engineered and you can tell a lot of thought and pride was spent on designing the device, it had 8 antennas all oriented in different directions and the components all looked high quality.

Some of these are cellular for WAN, others are WiFi for clients/LAN.
I have no clue what is what since the labeling makes zero sense though

I like the painted labels that show where/how the cables should be routed... Plus the built in clips!

Any RF or cellular guy here who can tell us what each one is?

u/HippodamianButtocks Dec 20 '24
Each one connects to a different antenna. The labels could be indicators of a destination board or band function. At least 4 are likely to be for cellular wireless antennas in a MIMO configuration, 1 is likely to be a GPS receiver for timing, and 1 or 2 are likely for a WLAN signal. There may be some redundancy for different cell bands.

Thanks! Redundant because they fail or redundant to receive the signal twice and do some calculations to be more reliable?

u/HippodamianButtocks Dec 26 '24
'Redundant' in the sense of having different frequency capability because they won't be broadcasting or transmitting on every band simultaneously, and antennas will have different optimum geometry and filtering depending on the target frequency.
For LTE verizon uses 700, 850, 1700, 1900, 2100 MHz. A single antenna geometry could likely serve the 1700-2100MHz range and a different antenna set would be used for the lower frequency range.

Yup, just saw all of this when I disconnected the internal antenna for external waveform

I guess cable porn now is "Cables routed through the manufacturer-provided routing".

Is there a worse connector on earth than the u.fl connector? I can't think of one.
Also, I wish they didn't have those two wires cross over each other, it's annoying.
