A recent report by the Department of Homeland Security’s Office of Inspector General (DHS OIG) revealed that the radio communication system used by the Secret Service is out-of-date.

Radio systems are critical to the day-to-day protective operations of Secret Service, making 100 percent operational success imperative. However, DHS OIG’s testing revealed “inherent radio limitations” and “unclear transmissions,” which could lead to a communications failure in an emergency. The exact age of the current radio infrastructure was redacted from the report.

Additionally, DHS OIG reviewed Secret Service’s Radio Trouble Log, documenting technical issues that interrupted communications during an 11-month period; more than 100 instances of technical issues were detailed.
