The Project Lifesaver transmitter operates within a radio frequency (RF) range of 216-218 MHz. This specific frequency is crucial for its function in locating individuals who may wander due to cognitive conditions.
Understanding Project Lifesaver's Frequency
Project Lifesaver is an innovative program designed to provide rapid response for locating individuals with Alzheimer's disease, autism, Down syndrome, dementia, and other cognitive conditions who are prone to wandering. The core of the system relies on a small, personal transmitter worn by the participant, which emits a unique, intermittent radio signal.
Key Aspects of the Project Lifesaver Transmitter's Frequency:
- Frequency Range: The transmitters are engineered to produce an RF signal within the 216-218 MHz range. This range is specifically allocated and managed to ensure effective tracking without interference.
- Signal Type: The signal produced is intermittent, meaning it sends out short bursts rather than a continuous stream. This design helps conserve battery life and makes the signal easier to detect by specialized receivers used by search teams.
- Wearer Experience: A key benefit of this chosen frequency is that it is unheard by the wearer. This ensures comfort and discretion, as the individual is not bothered by any audible noise from the device. This silent operation is vital for maintaining the comfort and cooperation of the program participants.
How the Frequency Aids Location
When a Project Lifesaver participant goes missing, trained search and rescue teams, often from local law enforcement agencies, use specialized tracking equipment. These receivers are tuned to detect the precise 216-218 MHz frequency emitted by the participant's wristband or ankle bracelet.
Advantages of this Frequency Range:
- Reliable Detection: The 216-218 MHz band allows for effective signal penetration in various environments, including dense foliage and urban areas, aiding in quicker location.
- Dedicated Use: This range is often dedicated or managed for specific public safety applications, reducing the likelihood of interference from other common electronic devices.
- Directional Tracking: The nature of radio signals at this frequency allows receivers to determine the direction from which the signal is originating, guiding search teams directly to the missing individual.
The table below summarizes the technical specifications related to the Project Lifesaver transmitter's frequency:
