How Wi-Fi communication helps in lone worker safety?

Wi-Fi network can be used for locating lone workers, calling and sending data over Wi-Fi. Both location and communication are essential features in lone worker safety; lone workers need to be found and to be able to alert help at any time or moment of their work shift.

Many lone working duties are accomplished in poor mobile network signal areas like caves, basements, underground sites, rural areas or other areas where cellular signals are weak for example because of bad weather conditions. The established Wi-Fi base stations or access points can compensate the poor or missing cellular signals and provide an alternative communication network for lone workers to call and send messages in emergency. The advantages of Wi-Fi network for lone worker safety are its easy set up, low costs, flexibility, accessibility and constant connectivity.
