The purpose of dataFM is to notify the public in the event of an emergency utilizing the most effective form of communication - FM radio
RDS2 VS OTHER WIRELESS SYSTEMS
The emergency notification systems comprise equipment to be installed at the existing radio station transmitter site.
For example, with an RDS2 system, it is not necessary to build cell towers, buy transmitter equipment, obtain a broadcasting license, maintain broadcasting towers or equipment, etc. This system not only saves money, but time and maintenance as well.
The RDS2 system can be owned by Emergency Management. Emergency Management relies on the good will of cell phone system owners.
The Data FM system has scalability in pricing. There are individual receivers that can be installed in existing PCs, tablets, laptops or other computer devices at pricing below a standalone receiver. Standalone receivers are also available.
We have receivers that function for the disabled. For the deaf it has a strobe light and for the blind it converts text to speech.
These systems are both wireless and wired. Wireless can communicate from either point to point or point to multipoint by way of the broadcast signal and the wired can respond from each receiver to the sender point to point.
The receivers can also create contact closures for the remote operation equipment using RS232 or WiFi connections.
HOW IT WORKS
The system works as follows:
A sender communicates over the internet, through police push to talk two-way radio or satellite to any number of FM transmitters. The FM transmitters broadcast to FM receivers that decode the data in the signal and display text and images on displays in the receivers. Once a receiver receives the message it reports back via an internet connection to the sender to confirm that the particular receiver received the message. This process can be done silently daily to confirm that all receivers are functional without human interaction. Thereby providing and confirming a reliable delivery of messages in the event of an emergency.
