What is the problem?
High Frequency (HF) tactical radios offer tremendous benefits to warfighters due to their long-range communication capability when aided by favorable ionospheric conditions. However, this benefit is significantly hampered by lack of “dependability”, i.e. whether the link can be established or not, and how long the link will remain alive even if established. Consequently, the instability drastically outweighs the benefits of HF, because there is no assurance that warfighters can establish critical communication on demand, thus limiting the use of HF radios for critical battlefield situations. Another significant challenge for existing HF tactical radios is that they cannot establish a communication link without pre-planned frequency planning, even if they all support multi-band modes.
