In a typical hardwired lighting system, control signals are sent using communication wires. However, the wiring of this system can emit electromagnetic frequencies (EMF) that contribute to disturbances in sleep patterns . In a wireless RF system, control devices communicate through the air using radio frequency waves , which eliminates the need for control wiring, also decreasing patients’ exposure to unhealthy energy that can contribute to disturbed sleeping patterns.
Continuous low-level human exposure to RF fields produced by base stations and local wireless networks have shown no detrimental effects to human health. RF radiation is at the low energy end of the electromagnetic spectrum. The body is exposed to five times more of the signal from FM radio and television than from base stations. Below are the listings of frequency levels emitted for different devices:
- FM radio: around 100 MHz
- TV broadcasting: around 300 to 400 MHz
- Cell phones: around 800 MHz
- Wireless technology : 900 MHz and 1800 MHz
The low level of RF fields emitted from wireless technology does not have enough energy to directly damage humans.
Problem: Continual exposure to the weak EMFs that are emitted from typical hardwired lighting systems at night can decrease melatonin production, which is essential for getting healthy sleep. Melatonin disruptions can lead to adverse health effects in humans.
- Specify a wireless control system that provides diagnostics of existing lighting system
- Provide occupancy sensors, photosensors, or low-voltage relay switches for the wireless control
- Provide control of lights and sensors through personal computer or phone
- Wireless drivers allow for the possibility to work in a tight area
