The WAVE is a wireless instant notification system. It is the fastest and most effective way to communicate an alarm to first responders. An audible alarm message over a two-way radio or push-to-talk phone is the most urgent type of message. It demands attention. The WAVE can also send e-mails and text messages or make phone calls. The WAVE uses state-of-the-art technology to provide wireless sensors with either the longest range and most robust signal or the most accurate RF location available.
