Verizon Jetpack LTE portable hotspot teardown.
« on: February 22, 2015, 10:17:56 pm »
Found this little guy sitting on the sidewalk where I walk my dogs.  We have a neighborhood association so I posted it on lost and found.  No one claimed it, so, it belongs to posterity now.

That strange looking thing is a chip antenna.

Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

Thanks!  For what do you imagine?  WiFi?  LTE?

That's probably the LTE antenna. You can see the two microstrip lines leading to it from the shielded can containing an RTR8600. That turns out to be Qualcomm's multi-mode cellular transceiver.

I can't actually spot the WiFi antenna. Perhaps it's at the end of microstrip line on the corner next to the same can.

I think the chip antenna is being used both for primary and diversity antennae. Does anyone know if it would really work? The two parts seem to be too close to be useful for diversity receive.

WIFI antenna is under the front plastic, you can see the slot antenna there in the top cover.

Yes, there are two antennae connected using spring contacts you can see in the image below.  :-+  (I thought were capacitors  :-// )

An unpopulated connector near the battery seems to be MDM's JTAG
