The cellular network users are demanding more traffic and expecting a ubiquitous high data rate. Several techniques are investigated to cope with this massive demand. All the current solutions are focusing on improving this issue from the supply side. However it is expected that a significant improvement on the system performance can be gained if the end users become a part of the system and not just consumers. The user-in-the-loop (UIL) spatial approach provides a solution to fulfil the increasing traffic demand by convincing users to move to locations with higher SINR values. The previous results of the UIL are promising and a higher cell spectral efficiency is achieved only by the involvement of the users and without any investment on the supply side. UIL is a user-centric approach that offers an incentive to influence users' behavior to participate in the system improvement process. In this paper, the previous ideal environment of UIL is extended by integrating the important effect of correlated shadowing to the analysis of UIL performance. The obtained results in this paper confirm the previous results and promise significant performance improvements. Results show that the achieved higher spectral efficiency and the required moving distance depend on the correlation parameters.
