Transmit power measurement results of configured-maximum-transmit-power-controlled mobile phones in hospital

Abstract

Reducing the transmit power of mobile phones is effective in preventing electromagnetic interference (EMI) with medical devices in hospitals. However, to our best knowledge, no study has shown transmit power measurement results of mobile phones for which the configured-maximum-transmit-power was controlled by specific base station (BS) parameters. This letter shows transmit power measurement results from a mobile phone for which the configured-maximum-transmit-power is experimentally controlled by indoor BSs in a hospital. Reduction in the mobile phone transmit power and the issue of preventing EMI with medical devices are discussed based on the measurement results.
