Hospital staff today use communications devices to coordinate nursing activities within hospital departments, and they also use communications devices between teams such as management, nursing, building maintenance, security, ambulance EMS staff, and others. These must be effective, simple to use, compact and lightweight. The SD7 Rugged PTT Handset, with its optional VK7 Vehicle Kit for ambulances offers that quality of service. The SD7 Handset is an ideal replacement for legacy LMR two-way radios since it looks, feels and operates just like a handheld radio, but it operates on a cellular network. The SD7 Handset can also work over Wi-Fi networks if there are parts of the property, such as a basement, where cellular signal is not strong.
