Originally aired: Thursday, December 6, 2018 -- 11:00 AM PT/2:00 PM ET

Narrowband Land Mobile Radio (LMR) networks and user radio equipment have been the cornerstone of mobile communications for First Responders for decades. The trend from traditional analog to more robust wireless broadband networks in recent years has improved the overall accessibility but questions remain on whether the new networks can provide all the required capabilities First Responders need to do their job.

Increasing demand for bandwidth intensive applications such as video, advanced mapping and analytics, alongside critical voice communications has been driving adoption of broadband LTE cellular networks, such as FirstNet.

Join our panel of industry experts for this insightful 60-minute on-demand webinar as they discuss the critical differences between LMR networks and LTE networking, how these technologies can successfully co-exist, and explore the future of critical communications for First Responders.

In this session, you will learn:

  • Current and future industry trends for LTE and LMR technologies
  • Challenges and obstacles with the convergence of technologies
  • Real-life examples of successful hybrid communication strategies for First Responders
  • Recommendations for future proofing your agency; adoption of new technologies and how to bridge the gap

Originally aired: Thursday, December 13, 2018 -- 11:00 AM PT/2:00 PM ET

An exceeding number of police departments and law enforcement agencies, whose officers spend upwards of 3-4 hours a day completing incident reports and other time-sensitive paperwork*, are turning to smarter tools, such as speech recognition solutions, to help transform their police reporting workflows.

View this on-demand webinar to hear why these law enforcement professionals are embracing smarter tools to complete higher-quality reports and move mission-critical information within the CAD/RMS faster and more efficiently – all by voice.

This discussion will provide you with an understanding of:

  • What law enforcement has to say about current reporting processes
  • Why officers, especially recruits, want smarter tools to help with police paperwork
  • Why manual reporting has a negative impact on report accuracy and productivity and can hinder criminal proceedings
  • How departments can speed up data entry within the CAD/RMs and move mission-critical information more accurately and efficiently
  • How speech recognition technology can help increase officer safety and improve situational awareness and productivity on patrol
  • Why embracing smarter technology increases community visibility, and minimizes costs

Learn how your department can make incident reporting faster, safer and more complete by viewing our on-demand webinar today.

Things That Go Boom in the Night

Advanced techniques can help you detect all manner of explosives.

June 30, 2010  |  by Tim Dees - Also by this author


With the exception of far-less-common biological or radiological threats, explosive devices are the nightmare scenario for people charged with protecting people and places. In most cases, no one knows of the device until detonation, and it may take out first responders as well as private citizens.

This is because devices reside inside commonplace objects like books or backpacks that people see and don't notice. They may trigger via a timer, a switch activated by pressure, proximity or movement, or by remote command. Reliable detection of the devices is difficult because of their small size relative to their lethality. Science is getting better at this, but the more traditional methods also have their place.

Know Your Explosives

The earliest explosive was black powder or gunpowder, made of sulfur, charcoal, and potassium nitrate (also called saltpeter). Anyone reading this article is probably familiar with the characteristics of gunpowder. It's fairly easy to manufacture, but it's a low explosive, capable of propelling a bullet out of a gun barrel, but not destroying the gun itself (unless one overpacks the cartridge, which is more of a function of stupid than physics).

Nitroglycerin came along a bit later. It has a greater energy density than black powder, but its sensitivity to shock makes it difficult to work with, and it is rarely used today for anything except as a vasodilator medication.

Alfred Nobel invented dynamite by combining nitroglycerine with sodium carbonate and diatomaceous earth. The latter ingredient is available at any garden nursery, made of ancient decomposed sea shells. Dynamite was the first commercially viable explosive, and made Nobel wealthy enough to endow an annual prize for advancements in science and in peacemaking.

Dynamite is usually formed into sticks and wrapped in paper. Over time, the nitroglycerine in the dynamite will "weep" or "sweat," forming unstable crystals on the wrappers. Proper storage of dynamite dictates the packages be turned periodically to prevent this.

Some people think trinitrotoluene or TNT and dynamite are the same thing, but they aren't. TNT starts with toluene, a common solvent used in model airplane glue, among other things. The explosive is produced by repeatedly nitrating it with nitric and sulfuric acids. TNT is more stable than dynamite, and can be poured (it melts at 176 degrees Fahrenheit) into molds or combined with other explosives. Maybe that's why it's the most common explosive in conventional military munitions such as artillery and mortar shells.

TNT is the standard for measuring the destructive power of other compounds and weapons. The "Little Boy" atomic bomb dropped on Hiroshima in World War II was equivalent to about 15,000 tons (15 kilotons) of TNT. Modern nuclear weapons are measured in megatons, or million tons of TNT. To provide perspective, a kiloton of solid TNT would be a cube measuring about 10 yards on each side. Interesting bit of trivia: TNT is yellow, and skin that's in repeated contact with it turns the same color.

Terrorist bomb makers prefer plastic explosives. These are compounds containing one or more of the explosives already described, plus pentaerythritol tetranitrate (PETN) or RDX, plus wax or some other plasticizer. The resulting compound is a moldable, castable substance that can take almost any physical shape. PETN is a major ingredient of Semtex, while RDX is used in Torpex and C-4.

Umar Abdulmytallab stashed PETN in his underwear in December 2009 in his unsuccessful attempt to destroy Northwest Airlines Flight 253 between Amsterdam and Detroit. RDX was the primary explosive in the 2006 railroad bombings in Mumbai, India, and in the bombing of the Moscow Metro earlier this year.

Most, if not all, explosives developed since black powder have nitrate compounds as a base component. It's these nitrate molecules and ions that high-tech bomb "sniffers" look for. Plastic explosives tend to be denser than other common materials carried by travelers, and the explosives are sometimes surrounded by wires, batteries, or electronics that complete the bomb. These are detectable with X-rays and other visual scanning methods.

When these methods fail, or when the gadget locates a suspicious lump that might be a bomb, somebody has to take a look with his or her own eyes or a remotely operated device. Of course, you can always blow the thing up wherever it happens to be, but the people who own the venues usually prefer you not do that.
