Any way to identify a small cell using Field Test mode on an iPhone?

Recommended Posts

I'm detecting new PCIs on my phone and I can't tell what they are or where they are exactly. Is there any information in Field Test mode that would indicate if a particular PCI is a small cell or mini macro?

A good rule of thumb is PCI > 400 is highly likely to be a small cell or mini macro of some type.

PCI > 480 is usually a femto cell class device like an Airave 3 or a Magic box.

We have lots of macros in Seattle with PCIs up to 440.

Very true. I've noticed some in my market as well. Though generally speaking it's a good rule of thumb.

Does field test show the earfcn? That could be used as well.

Yes it does. I was going to suggest looking at that.

So there is no more cell identity on the iphone anymore? That used to equal gci when converted.

There is. Oftentimes the fields just take a while to populate.

Yup. On Intel devices it should be under LTE > Serving Cell Meas > phy_cell_id I believe.

earfcns I got are: 8109, 8109, 8775 and, 8109.  

Not a small cell. That's likely a new macro. 8109 is a typical 5x5 L1900 A block carrier and 8775 is the 3x3 L800 carrier by the canadian border.

Quite curious as to where they could be. I know where one of them is but not the other three.

I know where all the macros in town are. I have no idea where these new ones would be. It's a town of 50,000 so there's no high capacity sites.

Sorry until signal RSRP reads -75 dBm, not speeds, if that was what you were after.
