History
“One beautiful morning while surveying a cell site located on a high-rise rooftop, I met a man named Joseph resting comfortably, enjoying his lunch and the incredible view. I introduced myself and told him that he should not rest in that particular spot because the ‘things’ directly behind him were active antennas and they generate radio frequency (‘RF’) emissions. Joseph, an HVAC technician, almost fell off the roof! With eyes wide opened, he started asking: Which part are the antennas? What do they look like? What is RF emission? What happens when you get exposed or over-exposed? Am I in danger? Where are the safe and unsafe areas? What do those RF signs mean? That was many years ago but Joseph was so concerned and genuine that I still remember his face to this day.”
That fateful morning led Darang Tech, a registered Professional Engineer to found Dtech Communications, a wireless engineering services company focused on providing RF (radio frequency) emissions safety analysis, and compliance solutions. With a strong wireless engineering background, Dtech helps cell phone companies, broadcasters, building owners and government agencies to comply with FCC (Federal Communications Commission) and OSHA (Occupational Safety & Health Administration) safety regulations pertaining to RF exposure.
