Wireless electronic systems have been relying on dish antennas to send and receive signals. These systems have been widely used where directivity is important and many of those systems work well at a relatively low cost after years of optimization. These dish antennas having a mechanical arm to rotate the …

Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. “Free space” means air, outer space, vacuum, or something similar. FSO operates on the Line-of-Sight phenomenon, consisting of a LASER at source and detector at …

One of the most common functions in all electronic circuitry is switching. Switching has a wide range of uses. Engineers in industries ranging from telecommunications to military/aerospace need high-performance RF/microwave switching as part of their test setups. An RF switch or microwave switch is a device to route high frequency …

In 2016, The Army’s chief information officer announced the release of the Army’s new, long-term, network strategy called “Shaping the Army Network (2025-2040).” The document discusses the projected operational environment and required capabilities to set the context for what the future network must enable; describes what the network of 2025 …

The goal of future generation networks is to meet the future communication needs of the information societies such as Smart infrastructures, Smart City, Smart Grid, Smart Health, and Smart Transportation. The future will be a completely data-driven society in which people and things are connected universally, almost instantaneously (milliseconds) to …

Unmanned Aerial Vehicles, abbreviated as UAVs, are aircrafts without any human pilot onboard, mainly controlled and managed remotely or via embedded autonomous computer programs. UAVs are also popularly known as drones. Unique features of UAVs pertaining to high mobility in three-dimensional space, autonomous operation, flexible deployment tend to find appealing …

As the Military and civilian technological systems, from fighter aircraft to networked household appliances, are becoming ever more dependent upon internet, they are also becoming more vulnerable to hackers  and electronic intruders. Electronic system security has become an increasingly critical area of concern for the DoD and the broader U.S. …

The development of precise atomic clocks plays an increasingly important role in modern society. Shared timing information constitutes a key resource for navigation with a direct correspondence between timing accuracy and precision in applications such as the Global Positioning System.   Atomic clocks are one of the most accurate time …

Mobile communications systems have evolved through wireless technology innovation into 2G, 3G, and then 4G to keep pace with ever increasing voice and data traffic. 5G, short for 5th generation mobile networking or 5th generation wireless systems is the latest iteration of cellular technology that will provide seamless coverage, high …
