Emergency wireless communications

Mitsubishi Jisho Property Management Co., Ltd.

Mitsubishi Jisho Property Management (MJPM) is the property management arm of the Mitsubishi Estate Group, which has a strong track record across many types of office buildings, building complexes and commercial facilities. As well as building management operations, MJPM offers a total management solution to breathe life into local areas.
MJPM has already sourced multichannel access (MCA) transceivers so that the buildings it manages have access to the MCA wireless communications network in the event of a disaster. MJPM decided to install the wireless equipment in the buildings it manages across Japan because of its high capability of voice communications even in case of a disaster while other networks were unconnectable in the wake of the 2011 Great East Japan Earthquake. While various emergency communications networks exist, this system has been proven to combine high reliability and simplicity at low cost.
