Potential cyber attacks have a lot of people worried thanks to the recent conflict in Ukraine. So it might be appropriate to review what happened when cybersecurity firm FireEye’s Mandiant team demonstrated how to infiltrate the network of a North American utility. During this exercise, Mandiant hacked into the utility’s industrial control systems and switched […]

Battery backup chemistries for 5G small-cell sites
As the number of cell sites increase and their sizes decrease, engineers have options to consider for battery backup. Differing battery chemistries offer more choices and different performance levels. Selecting the right battery chemistry for each application is critical to ensure reliable, long lasting, and cost-effective power delivery.
How coherent optics increase data rates
Modulation and polarization multiply data capacity on optical networks. In the beginning of optical networks, all optical signals were based on a simple mechanism known as on-off keying (OOK). In simple terms, this mechanism works by switching a light on and off to transmit data. OOK is a wider definition for representing whether data is…

GNSS receivers to get OSNMA functions
Septentrio announced the release of OSNMA functionality on their mosaic GNSS receiver modules. OSNMA (Open Service Navigation Message Authentication) offers end-to-end authentication on Galileo’s civilian signals, protecting receivers from GNSS spoofing attacks. Spoofing is a malicious form of radio interference, where faulty positioning information is sent to the receiver. For the last 2 years, Septentrio […]
What’s the difference between network security and physical security?
Network security involves software and computer-based hardware/firmware to provide access to the authorized and restrict access to the unauthorized. In contrast, physical or brick and mortar security starts with sensors and, if the security system is connected to the internet, it also requires the same network security measures. Protecting a residence, commercial building or an […]
Difference between a waveguide and transmission line
As electronics migrates to higher and higher frequencies, the media routing electronic signals to their intended destinations grow increasingly exotic. This is particularly true as communication technology moves to 5G frequencies which are characterized by millimeter wave transmissions. In this frequency range, engineers are more likely to encounter waveguides and transmission lines rather than ordinary […]
Measurements show 5G improves latency in public networks
Measurements on public networks at our facilities demonstrate how 5G’s lower latency compared to LTE can improve industrial applications.
