More Interference for DoD On the Way?
A Word from Sam Benzacar
As we’ve noted before in this column, the Department of Defense faces interference challenges at least as daunting as the commercial wireless industry. This situation looks likely to become even more challenging in the future because military radar and satellite communication systems operate at frequencies well into the millimeter-wave region, which is precisely where the fifth generation of cellular is headed. In addition, the FCC’s recent successful spectrum auction has given T-Mobile significant assets at 600 MHz, which is the figure shows covers almost the entire United States. Others gained 600 MHz spectrum as well.
This is obviously not the first time the DoD has had to contend with services encroaching on its allocated frequencies. However, even though frequency sharing will be employed at the millimeter-wave frequencies where military satellite communications systems operate, the potential for interference still exists. And allocations below 1 GHz are already so densely populated that even if the fundamental frequencies don’t create problems, harmonics and spurious signals quite possibly will.
It’s not an insignificant problem for a mission-critical resource such as the military, and it will inevitably require DoD to step up its spectrum monitoring activities in an attempt to ensure that interference doesn’t cause major problems. However, it will also inevitably need what RF and microwave filters have always delivered--extremely high levels of interference rejection, not just for systems and development but for those in the field. In the latter case, filters represent the only viable way to cost-effectively mitigate interference, as a complete redesign is obviously not feasible. Fortunately, filters have a long track record of fending off interference effectively at frequencies throughout the electromagnetic spectrum.
Anatech Electronics also has a long track record of solving interference problems for defense systems on the ground, in the air, and aboard ships. We offer standard filters for every frequency range used by DoD, the Department of Homeland Security, and other defense-related organizations. We also have the ability to design custom filters in a short time as we’ve created a library of more than 5,000 filter designs that can be easily modified for any requirement.
