  • This appears to be a solid product. I like the remote monitoring feature because what happens if your public safety booster goes down without you knowing it and first responders show up? They could lose their signals with each other and I’d have to think there might be liability on your end. Being able to check it remotely is a great way to keep up on things.

  • “Why does the signal of mobile phones fluctuate?” There are so many reasons this can happen. Your cell phone picks up a signal from a tower which can be affected by how far away the tower is, geography interfering with the signal (such as trees, hills, etc.). Then, your phone has to deal with interference from whatever structure you’re in, be it a home, mall, or office. Building materials can weaken or even block a signal (think of what happens when you’re in your basement or an elevator) which can only make things worse. Last but not least, bars are a poor way to judge your signal. Go to your phone’s settings and check your signal through there.

  • I know I’m not the only person who experiences this—why does the signal of mobile phones fluctuate? Sometimes it’s full power, others it’s just one bar.

  • A BDA system design will prepare your facility so first responders won’t have any trouble communicating. While this blog doesn’t go into detail on what a BDA system is, you can find some excellent explanations elsewhere on this site. Basically, a bi-directional amplifier boosts as cell phone boosters do, allow first responders to get a strong signal to each other. It’s not only wise, but I believe it’s required by law. You might want to check your jurisdiction. Either way, it’s good to have.

  • Public safety officers and officials have enough on their hands without having to worry about getting a clear call to their colleagues. I like the way this sounds. I also like the idea of lifetime technical support. I’m sure there are updates on these products so it’s good to have a line to the people who know how they work the best.

  • This was cool to learn about. I like the way it automatically checks for problems from repeaters and new cell towers. I have a couple colleagues who are first responders so I’m interested to hear what their experiences have been and what system they use. This could be a great addition for their agency.
