One of the fundamental elements in order to implement context aware scenarios to enable the deployment of Smart Health is the use of wireless transceivers. Modern wireless systems make use of high order modulation schemes in order to increase spectral efficiency dynamically, leading to interference dependent coverage-capacity relations. In this work, performance of wireless sensor network nodes deployed in an Emergency Room complex will be analyzed in terms of topological dependence and the influence to non-desired interference sources. The results provide estimations in order to adequately deploy multi-system wireless systems in order to increase the system capacity and to reduce the overall interference levels.
