Pepro uses a patented Faraday Cage system to ensure that communications are not interrupted by Radio Frequency Interference (RFI), Electromagnetic Interference (EMI), Electromagnetic Pulse (EMP), and Passive Inter-Modulation (PIM), lightning strikes and transient voltage.

Pepro manufactures units that can meet the needs of small and large organizations alike. The units can be installed permanently or temporarily in urban, rural, or remote locations.

Pepro specializes in mobile and remote communication shelters. Mobile units are often called Cell on Wheels (COWS), Site on Wheels (SOWS), Tower on Wheels (TOWS), or Mobile Tower Units (MTU). Many municipalities are looking to Pepro's mobile units to ensure communications during emergencies or natural disasters. The U.S. Forest Service has utilized many of Pepro's integrated fixed radio sites or walk-in unitsin remote areas; i.e.: in the National Forest or on mountain tops in the western U.S.
