Which capability does EHF provide?

The correct answer highlights the capability of Extremely High Frequency (EHF) communication systems, which are designed to operate at frequencies between 30 to 300 GHz. One of the primary advantages of EHF communications is their low probability of intercept (LPI) and low probability of detection (LPD). This characteristic is vital for secure military communications, as it makes it challenging for adversaries to intercept or identify the communications being transmitted.

By utilizing EHF, military operations can maintain secure and reliable communication links, even in contested environments or where enemy surveillance is a concern. The LPI nature of EHF supports the need for stealth in military operations, ensuring that sensitive information can be communicated without the risk of being easily captured by enemy forces.

The other options, while related to communication capabilities, do not accurately define the unique advantage of EHF systems. For instance, while EHF can provide high bandwidth capabilities, it is primarily recognized for its low intercept capability.
