Coexistence possibilities of LTE with ISM technologies and GNSS

Interference due to in-device coexistence of multiple radios operating simultaneously in adjacent or overlapping radio frequency spectrum is a big issue. In this article, we understand the nature of issues related to coexistence of LTE with ISM technologies (Bluetooth, WiFi) and GNSS in a mobile handset. Each of these technologies have different characteristics such as different access mechanism, frame structure, peak transmit power and operate in different frequencies. We analyze the charecteristics of each technology and propose possible direction so that in-device coexistence interference for certain popular use cases can be mitigated.
