There are various services that utilize the users’ location. It's important to accurately estimate the location for the QoS of these types of services.
Since GPS signals cannot be received in indoors, it is difficult to estimate a user's location indoors.
- We replaced the GPS signal with the 2.4 GHz ISM band RF signal used indoors.
- Estimate the location at low cost by using the already installed infrastructure.
IPS with Mathematical Modeling
with respect to signal strength, time of the signal arrival, or angle of arrival.
IPS with Deep Learning
using DL models such as RNN or LSTM which extract features from sequential data.
