Abstract
We consider the crowdsourcing based mobile cellular network
measurement paradigm that is becoming increasingly
popular. In particular, we aim to study the impact of user indoor/
outdoor environment context at time of measurement.
Focusing on signal strength as the measurement metric and
using a real large crowdsourced measurement dataset for
central London area along with estimated environment state
(indoor or outdoor), we show that indoor-outdoor context
has a significant impact, suggesting that conflating indoor
and outdoor measurements can lead to unreliable results. We
validate these observations using a set of diverse and controlled
measurements with indoor/outdoor ground truth information.
We also discuss some opportunities for future
work (e.g., accurate and efficient context detection) relevant
to crowdsourced mobile network measurement systems.
