C4i successfully completed Mil Std-810 Altitude qualification testing for its Radio Interface Unit (RIU). The assessment was conducted by an independent test facility in Virginia, and involved running the RIU at an extremely low temperature (–60°F) in a decompression chamber continuously for seven days.

Altitude testing is performed to determine whether the hardware can withstand and operate in a low-pressure, low temperature environment. The assessment mimics the effects of a high-altitude setting and simulates extreme cold weather, thereby proving the RIU’s environmental survivability and its ability to function at great heights, even during potentially freezing temperatures.

C4i’s RIU can be implemented as part of a radio gateway at an unmanned, remote radio site on a mountaintop, and operate without failing. The RIU connects to the radio system and converts voice signals from the radios into IP for transport across the network. C4i’s ultra-rugged hardware ensures that the signal will get through regardless of the conditions.

Moreover, C4i subjected its RIU to a series of “mil-standard” drop, shock, and vibration tests in order to further demonstrate how rugged the equipment actually is. These tests illustrate the RIU’s ruggedness, and ensure its ability to function in unforeseen conditions, such as in a mobile or transportable operation, or in earthquake zones. Even when exposed to environmental hazards, the products will provide guaranteed performance.
