Due to space and time restrictions, information concerning the Harris Adaptive Networking Wideband Waveform (ANW2) was unfortunately received too late to be included in our article on the evolution of SDR - Defining Software-defined - found on page 16 of this issue. Most certainly worthy of mention, the ANW2 has been operated by US forces in Afghanistan on the company's AN/PRC-117G (photo) radios, and Harris is in the throes of developing a wideband version of its AN/PRC-152(C) using the same waveform. The ANW2 provides a mobile ad hoc networking infrastructure for shuttling voice and data through difficult terrain, including around buildings and mountains. The waveform allows each radio within the network to operate as a relay station, to help ensure signal delivery throughout the network.
Harris put its experts to task over a four-year time period and in 2007 unveiled the ANW2 waveform, which requires no infrastructure, no pre-configured head or cluster nodes. A high security profile was also a consideration, as the data is encrypted using the Haipe standard. Fast network forming and quick healing times when signals are lost give the fast-moving warfighter assurance that the connection will be quickly re-established. Further evolution of the ANW2 waveform will see the inclusion of dynamic bandwidth allocation and some other in-demand features.
