Anyone know what these connectors are for?

[Crane]

My pickup is a retired Nebraska highway department truck, and when I got it I found 6 connectors sitting in the back, and I don't know what they are for, and was wondering if anyone here recognized any of them.
The one on the right is labeled 802.11 b/g, so it has something to do with an internet connection. The second to right is labeled 3V/5V GPS, so it was obviously used with a gps. The rest I don't know. If it helps there is a small antenna run through the windshield, and a plastic plug on the roof where another antenna probably ran though. I realize all of this is very vague, so if more pictures or details would help, just let me know

Well, probably a couple business band (2-way) radios, which would probably be the two with the CB-like connectors... Some of the others could have also connected to a switch panel that controls warning lights... Scanners of some sort too, there's lots of stuff, someone might chime in if they know... Here in Nebraska we really don't pay attention to what things are, we just hook crap up and hope it works

Yeah most likely radios of some sort... probably properly installed too as the wires are still in... The trucks we have in FAA are like getto rigged in and the cables are all out in the open.

The white one is probably for a light bar, the black one is for a computer or somthing probably... and then yeah radios and gps and stuff.

Most likely a radio or two, possible a Driver Moniter system, GPS tracking/speed & brake monitering etc. It makes drivers aware of their bad habits, via beeping during overspeed/excessive accel:decel etc. and allows employer's to track their drivers, and who is driving what vehicle. Only way to know for sure is to follow the wires, grab a schematic if needed and see what they're wired into.

You could maybe even email this picture to the Highway Dept... some are good about emailing back, some aren't.

Thats a good idea, I might do that.
Thanks for the help guys, I wasn't sure if these were common connectors at all, but it sounds like its for pretty specialized things.

The gold one is an RP-SMA plug, for a Wi-Fi antenna as you figured. The silver-colored small one next to it is for a GPS antenna, the connector may be a type MMCX. The two larger round silver ones are TNC connectors, most commonly used for cell phone antennas. The other two connectors (on the left) are probably for some of those devices (cell phone(s), GPS, computer, etc.). If you want to remove them, it is probably best to follow their paths as much as possible to try to find the other ends. If you can remove the plastic plugs you describe, you may find some of the matching cables. Another good place to check is under the dashboard. Often, devices have one part in a place like where you found the cable ends, and the other part is the control panel which will be mounted on the dashboard or other place near the driver.

Can you take a better pic of the black connector? It looks like an ATX power connector.

The one labeled 800/2400 is a cellular phone antenna. The white one, with the GPS and Cellular antennas were probably for an AVL system (automatic vehicle location). The 2 larger connectors are TNC connectors, and are pretty standard. The GPS connection is a regular SMA connector.
