There is at least $40 worth of BOM cost from additional Antenna, baseband Modem and other RF Related Component. And it is not only Qualcomm which collect royalty on LTE, Ericsson, Nokia, ZTE and many others all collect royalty.
I do remember the royalty fees for Non-Smartphone ( Or Devices with only Data line ) were cheaper. But together it would still easily be $30+.
