Do you trust that our critical infrastructure remains connected during large-scale power or signal outages?
The 11th Corps Signal Brigade recently completed the 54-hour Noble Skywave radio competition to validate high-frequency communication protocols. The training tested the unit's ability to maintain connectivity via alternative methods during simulated signal degradation.
Why it matters
Maintaining high-frequency radio proficiency is essential for signal units to ensure continuous command and control when primary digital networks are unavailable or compromised during combat operations.
Personnel utilized single sideband, 2G ALE, and 3G ALE technologies to establish long-distance links. This multi-protocol approach is designed to maintain signal integrity during degraded network conditions.
The players
11th Corps Signal Brigade
An Army unit specializing in global communications infrastructure and command-and-control support.
Canadian Armed Forces
The national military organization responsible for hosting the annual Noble Skywave signals competition.
The details
Soldiers utilized single sideband, a method for transmitting voice or data by filtering out one half of the modulated signal to increase power efficiency, alongside 2G and 3G Automatic Link Establishment (ALE). ALE systems automatically scan available frequencies and initiate connections between radio stations without manual tuning. These tools function as part of PACE plans—Primary, Alternate, Contingency, and Emergency communication strategies—to ensure redundant connectivity for military command structures.
Timeline
July 2026: Pfc. Tyler Lavender participated in a High Frequency Skills Challenge.
October 20-22, 2026: The 11th Corps Signal Brigade competed in the 54-hour Noble Skywave event.
March 2027: The brigade is scheduled to conduct a low-power high-frequency radio communications exercise at Fort Hood.
The Tech Race
The 11th Corps Signal Brigade's participation in the Noble Skywave event underscores a broader shift toward hardening military infrastructure against electronic interference. By utilizing this international benchmarking program, the unit maintains its operational proficiency in long-distance, low-bandwidth communication channels.
The training focus on signal resilience primarily affects internal military logistics and command-and-control workflows for Killeen-based personnel. These drills prepare units to maintain operational readiness in environments where standard satellite or cellular network access is unavailable.
The takeaway
The unit remains focused on securing communication lines through redundant high-frequency protocols. Future performance will be evaluated during the low-power communications exercise at Fort Hood scheduled for March 2027.
What happens next
The brigade is scheduled to conduct a low-power high-frequency radio communications exercise at Fort Hood in March 2027.
