Do Walkie Talkies Work Underground?

Two-way radios provide good coverage in regions where mobile phones and other communication devices are ineffective, such as substantial open stretches in the middle of nowhere. On the other hand, two-way radios fail to communicate efficiently in some dead zones, such as elevators, tunnels, and basements. This could be a significant issue for persons who work in these industries regularly, such as construction, mining, and retail malls.

The Leaky Feeder is a type of antenna that we can use to provide coverage in these dead regions. A leaky feeder functions as a highly long antenna. A leaky feeder is a coaxial cable with small portions of copper shielding removed, allowing radio frequency (RF) signals to pass through. Leaky feeders are typically installed permanently to provide 24-hour communications, although they can also be installed temporarily, such as when communications are required underground in an emergency.

You’ll be able to communicate in locations you never imagined were feasible.

The issue at hand

Because radio signals travel in a straight path, signal strength and clarity are typically harmed when barriers such as hills, mountains, and buildings are in the way. Even on flat ground with no obstacles, distance alone can degrade signal strength to the point that it is too weak or lost entirely.

There are customised and portable construction systems that allow employees to communicate more smoothly and safely by bridging communications from beneath to above-ground. There are some customised and innovative solutions on the market, allowing you to connect in ways you never imagined. Here are a few examples of how this can improve your coverage in historically underserved areas:

Digital Repeaters on Their Own

Long Distance Radios Repeaters work like radio megaphones, amplifying your signal and extending your communication range. Your radio systems can communicate over a longer distance with a stand-alone digital repeater, even if there are barriers in the way. They can also connect several sites, allowing you to expand your capabilities while maintaining your privacy and security.

Radio System Charging using Solar Panels.

In isolated areas where power outlets are limited, solar power is an ideal power source. Digicom can supply mobile radio repeaters that you may transport to your site on a trailer or in the back of your car. A solar panel charger not only improves the reliability of your communications but also improves the safety of your communications, resulting in more productive and energy-efficient communications.

To talk over 4G/LTE, press the button.

You can use your smartphone as a walkie talkie by pressing the Talk button. This implies you can use a two-way radio to combine the wide-area coverage of a cellular network with the ease of using a cellular network. Press to Talk uses the power and technology of cellular networks, 3G/4G/LTE, and Wi-Fi to provide fantastic flexibility and coverage where it would be impossible or difficult to connect otherwise.

I would just like to say a huge thank you to the walkie talkies team for the delivery of my Pronto radios. I only ordered them at 4pm and they arrived next morning. Great initial communication and the radios exactly as described.

Dear Walkie-Talkies, I just wanted to say a massive thank you for my new charger pack what a fantastic handy piece of kit, it will serve me well on my motorcycle trips and when we go camping. Also may I say what a easy process it is to purchase from your website and the charger arrived next day. If I have any further requirements I will most certainly be coming back to you.

We have been working with Walkie-Talkies to equip our front of house and facilities staff with radio equipment for several years now. I have always found their personnel to be very personable, professional and knowledgeable. They have always strived to tailor solutions to meet our needs and our budget, even allowing us to trial equipment to make sure that it fitted our requirements. Their after care service is also excellent. I would most definitely recommend Walkie-Talkies’ services.

Was looking to upgrade to digital radios for my school and decided upon the Motorola DP1400 and has proved to be an excellent investment. The radios were great value and delivery came early the next day. Will definitely be using you again.
