Communications

Modern military operations depend heavily on satellite navigation, secure communications and precise timing. That dependence creates vulnerabilities: GPS and other satellite signals can be...

End-to-end encryption can keep the contents of a conversation private, but it cannot protect users if an attacker manages to take over the account...

Persistent surveillance is one of the biggest challenges in modern military operations. Conventional drones are limited by battery capacity or fuel, requiring frequent landings...

As wireless networks carry ever-growing amounts of data, communication systems face increasing pressure to transmit information faster while consuming less power and bandwidth. This...

Modern military operations are influenced by more than events on the physical battlefield. Social media posts, messaging platforms, videos, news reports and foreign-language sources...

Countering small drones has become increasingly difficult as unmanned aircraft grow smaller, cheaper, and more numerous. Traditional radar systems can detect many aerial threats,...

Every new generation of wireless technology places greater demands on the chips inside smartphones, base stations and connected vehicles. As 5G evolves toward 6G,...

Smartphones separate their cellular modem from the main operating system partly to prevent problems in one component from compromising the entire device. New security...

As wireless devices continue to multiply, the radio spectrum is becoming increasingly crowded. Smartphones, connected vehicles, industrial sensors, wearables and countless other devices all...

As military and commercial operations become increasingly dependent on satellite communications, protecting those links from interference has become a growing challenge. Modern electronic warfare...

Modern military communications systems face a persistent challenge: every network, radio, satellite link, and data channel experiences different types of interference, signal degradation, and...

Mobile communications have become essential for modern military organizations, but they also create a security challenge. Smartphones and tablets offer flexibility and rapid access...

Satellites have become a critical part of modern military operations, providing communications, navigation, intelligence and targeting data to forces around the world. As dependence...

As drones become increasingly common along national borders and around critical infrastructure, detecting them is only part of the challenge. Border security agencies also...

Wireless networks are expected to support far more than smartphones in the coming decade. Autonomous vehicles, industrial automation, critical infrastructure, and AI-driven services will...

Modern electronic warfare depends on the ability to detect, identify, and analyze electromagnetic signals quickly. As military communications, radars, and sensors become more numerous...

Cybersecurity advice is only effective if people understand it. Organizations routinely warn users about phishing, malware, trojans, and viruses, expecting those terms to communicate...

As mobile networks become more complex, managing them is becoming a challenge in its own right. Future 6G systems are expected to support everything...

Explosive ordnance disposal teams, special operations units, and emergency responders often face a difficult dilemma: gaining information about a potentially dangerous area without exposing...

Maintaining large electrical grids is a difficult and often dangerous task. Power lines stretch across vast distances, pass through hard-to-reach terrain, and require regular...

Maintaining reliable communications in congested or contested environments remains a growing challenge for military and unmanned systems. Most fielded radios still rely on omnidirectional...

The wireless networks envisioned for the 6G era promise enormous data rates, potentially reaching terabits per second. Achieving those speeds, however, requires the use...
