An optical network is a communication system that uses light signals, instead of electronic ones, to send information between two or more points. The points could be computers in an office, large urban centers or even nations in the global telecommunications system. These include limited range local-area networks (LAN) or wide-area …

DARPA MICEE to monitor and detect malicious activities in 5G/mobile infrastructure devices.
The New York Times reported that the US government has defined 5G competition as a “new arms race.” According to the report, “whichever country dominates 5G will gain an economic, intelligence and military edge for much of this century.” The transition to 5G is a revolution and “this will be …

Due to the growing, insatiable thirst for information, both commercial and defense communications are driving towards increasingly higher data rates and wider bandwidths of operation. This in turn is driving systems toward higher operating frequencies, which more easily supports larger channel bandwidths. For example, today’s cellular networks (i.e., cellular networks …

Terahertz (THz) represents the portion of the electromagnetic radiation between the microwave and the infrared region. It is within the frequency range of 0.1–10 THz, corresponding to wavelengths of radiation from 3000 to 30 µm. The advantages of the terahertz light are that they are non-invasive, intrinsically safe, and non-ionizing, …

Bluetooth, developed in the late 1990s, is a technology designed to enable short-range wireless communication between electronic devices, such as between a laptop and a smartphone or between a computer and a television. Bluetooth works by using radio frequencies, rather than the infrared spectrum used by traditional remote controls. As …

The falling costs of space launch and the increasing capabilities of small satellites have enabled the emergence of radically new space architectures—proliferated constellations made up of dozens, hundreds, or even thousands of satellites in low orbits. Several commercial companies plan to establish space internet constellations consisting of hundreds to …

Advances in automotive design have led to an exponential increase in vehicle electronics. Today’s vehicle design improvements are due in large part to the application of electronics to automotive systems. Vehicle functions are divided into systems and sub-systems to provide for passenger entertainment, comfort, and safety, as well as to …
