Technology Description

Background & Technology:

The US Army Research Laboratory (ARL) is a leading innovator in basic and applied research in electronic/radio frequency (RF) sensing and advanced electronic device technologies. The vision for this area is scalable, reconfigurable, and networked RF and radar technologies for a variety of emerging platforms.

The invented radio frequency link performance tool (RFLPT) process and system is used to predict RF network performance in a field environment. Essentially, the RFLPT process identifies all possible network-related direct transmitter receiver pairs or permutations within a given network and assigns a probability value to each permutation. This probability value is based on a connectivity confidence interval, which assumes the field-measured signal-to- noise values (in dB) at the receiver are randomly distributed according to a standard normal distribution function. This distribution function is based on the terrain integrated rough Earth model, which is used to determine propagation loss values. The key aspect of the system is the ability to calculate a probability value for successfully receiving a transmitted RF burst over ground RF links. This probability value results in a modeling tool that can be used to identify the most reliable RF routes within a given network.

In addition to supporting military RF network planning and optimization, the patented technology may benefit similar commercial applications, such as facilitating the planning of wireless networks including GSM, UMTS, LTE, and Wi-Fi.


  • Identifies most reliable RF links within a communication network
  • Provides information to determine the best routing options for a proposed or existing network
  • Countermeasures against “jamming” as the transmission of the radio frequency communication link occurs in either jamming or no jamming environments
