Umbrella 对比 Private Safety Network 的使用情况和统计数据

Private Safety Network joins individual users who share a common connection or setting, such as students in a local school, employees in a common workplace, people in adjoining neighborhoods, or a business or college with multiple buildings on a campus who want the protection, safety and convenience of a private communication system that communicates to all members simultaneously. Linking these networks provides a further benefit for networks with common interests, such as a hospital, a nursing home, and first responders that can then share the speed of encrypted communications with each other all at the same time. By also providing important information for key personnel; businesses, administrators and responders can manage emergencies successfully. The Private Safety Network app requires the user be a part of a Private Safety Network. Please see http://privatesafetynetwork.com for more information.
