IHFR gives the tactical commander alternate means of passing voice and data communications. It will use ground and skywave propagation paths for short- and medium-range communications. (1) The IHFR will selectively replace the current HF manpack and vehicular radios. This leaves little time for data sharing. Current demands on voice C 2 networks require a large amount of operational time dedicated to voice. The exception is using SINCGARS with the Tactical Fire Direction System (TACFIRE) or Advanced Field Artillery Tactical Data System (AFATDS). Voice C 2 information maintains priority over data in most networks. The CNR network assumes a secondary role for data transmission when requirements exceed the Army Data Distribution System (ADDS) or Mobile Subscriber Equipment (MSE) capabilities. The CNR network's primary role is voice transmission for C 2. Single-channel tactical satellite (TACSAT).Single-Channel Ground and Airborne Radio System (SINCGARS).Each system has different capabilities and transmission characteristics. The CNR network is designed around three separate radio systems. However, the increase in complexity and number of different radio types also increases the predeployment planning necessary to ensure completely operational communications networks.Ī. Joining active electronic and passive ECCM techniques with multiple radio sets in the C 2 system provides effective communications to control ground and airborne forces. Each system takes advantage of a different transmission path increasing the probability that at least one communications system will work at any given time.Ĭ.
The combination of high frequency (HF), very high frequency (VHF), and ultra high frequency (UHF) radios gives commanders redundant, but different, means to control their forces. This provides the maneuver force commander with a reliable multifaceted C 2 communications system. Single-channel radios are being upgraded or replaced. It degrades enemy forces' abilities to find, monitor, or destroy friendly systems.ī. Frequency hopping (FH) is a spread-spectrum radio technique. Adding electronic counter-countermeasures (ECCM) modules and devices makes radios and command and control (C 2) facilities more survivable. Modern semiconductor technology has made high-speed signal processing part of everyday life and has enhanced communications systems capabilities. Chapter 1 Combat Net Radio (CNR) DeploymentĪ.
