Low-cost BLE bracelet as patients monitoring platform: range restrictions

Abstract

This paper presents results of the signal strength of the BLE v4.0 protocol used by the low-cost bracelet in an indoor environment. Low-cost BLE bracelets can be utilized as a patient monitoring platform, because has the ability to measure the vital parameters of patients. Thus providing the possibility of usage in hospitals and nursing homes for constant monitoring of patients. The application such a bracelets in a real environment has several limitations, and one of them is the signal range of the bracelet tested in this paper. The obtained results are presented together with the simulations for the frequency of 2.4GHz.With a range of up to 18.03m for the low-cost BLE bracelet in an indoor environment with obstacles.
