The purpose of ARCHES is to provide voice and digital communications for hospitals in the event that an emergency incident disables telephone and internet services. Communication with other hospitals, incident command centers (EOC’s) and others is conducted through radio channels allocated to the Amateur service. Radio connection to Winlink worldwide servers provides digital communication both for conventional e-mail service and the transmission of ICS and HICS forms.
The ARCHES acronym stands for Amateur Radio Communication for Hospital Emergency Service.
The agency providing equipment for and served by ARCHES is the Capital Area Trauma Regional Advisory Council (CATRAC).
