There are several forms and causes of degradation in electric signals, both in the time domain and in the physical domain, including runt pulse, voltage spike, jitter, wander, swim, drift, glitch, ringing, crosstalk, antenna effect and phase noise.

The Joint Range Extension Applications Protocol (JREAP) was designed to provide a standard way to allow Link 16 and other critical tactical data link-based information to overcome line-of-sight limitations inherent in tactical radio terminals. Today, JREAP allows data to be used for situational awareness, planning and limited decision making.

There are three standards for Joint Range Extension Applications. The most complex is JREAP-A. This option provides the user interface software to configure the JREAP-A characteristics, such as role, Transmission Sequence List (TSL), and serial interface parameters, and to monitor the communications interface.

This capability does not include hardware or software to control radios and assumes this capability will be accomplished via other equipment such as the front panel of the PRC-117 or RCU for the ARC-210. This feature includes a USB to synchronous serial (25-pin) adapter for making the physical connection to the radio.

The JREAP-C standard allows for the routing or forwarding of Link 16 data over IP-based networks. JREAP-C implements Appendix C of MIL-STD-3011 revision A, using both Transmission Control Protocol (TCP) and Universal Datagram Protocol (UDP) internet Protocols (IP) as the means of communication. It can operate as either a client or server, supporting up to thirty-two connections (five standard), when using TCP/IP. When using UDP, both unicast and multicast connections are supported.

The JREAP-C standard makes use of the internet Protocol (IP) in conjunction with either the User Datagram Protocol (UDP) or Transmission Control Protocol (TCP). The IP suite is a standard set of protocols that is deployed worldwide in commercial as well as military networks. By using JREAP encapsulation over IP, JRE can be performed over IP-based networks that meet operational requirements for security, speed of service and so on.

The JREAP-B standard uses an Announced Token Passing protocol for half-duplex communications. This protocol may be used when several terminals share the same JRE media and take turns transmitting or in a broadcast situation when one transmits and the rest receive.

With the assistance of JREAP, messages sent via Link 16 can be broadcast simultaneously to as many users as needed – a key for better situational awareness and interoperability of NATO and coalition forces operating within a single battlespace.
