In tactical communications the link networks are the critical layer that connect brigade command posts and various operational units such as artillery and combat battalions together. The Combat Net Radio (CNR) systems provide communications for the front line troops equipped with portable and vehicle installed radio equipment allowing information and command messages to be relayed between the command centers and the operational units. However, seamless connectivity between the CNR network and the link network cannot be always provided due to incompatibility and limited functionality of equipment available.
