There is one universal law that applies to nearly every aspect of life: “Communication is key”. In the world of construction, this holds true 10 times more. Construction jobsites require employees to be easily reachable no matter where they are working. Instant communication is one of the main priorities, as jobsite alerts and updates need to be heard immediately. For this reason, you will always find jobsite communication radios in the hands of outdoor employees – almost as much as you will see construction hard hats everywhere! These are portable, handheld two-way radios that provide quick communication between jobsite workers. For example, construction superintendents can contact individual workers or reach out to the whole jobsite crew for important updates. Similarly, contractors, subcontractors, and workers from different trades can stay in constant communication even if they are far away from each other. This makes construction walkie-talkies a valuable communication bridge, and here are the top benefits of using them – including popular radio models from brands like Motorola, ICOM, Kenwood, Cobra, Midland, and Retevis.

Benefits of jobsite communication radios

All kinds of construction jobsites have noisy environments because of loud operating machinery and construction activities.

Workers are assigned roles in different – often remote – locations around a jobsite, so there has to be a common communication link that connects everybody to the same construction radar. Two-way radios are particularly useful for logistical communication where workers could be multiple floors away from each other. For example, a contractor on the ground floor can guide the lifting teams on the top floor about material updates. Similarly, crane operators can interact with the nearby material handling teams, superintendents, security personnel, and site managers. This ensures maximum site safety by simply allowing everybody involved to communicate clearly and instantly, preventing guesswork and delays. Here are the main benefits of using jobsite communication radios.

Push-to-Talk convenience

You can use your smartphone to contact someone working in a jobsite. However, this requires a far-reaching network, is quite expensive to make so many calls in a day, and will simply drain the battery more often. Two-way radio units are purpose-built for jobsite communication, and apart from the purchasing cost, there are no subsequent service charges – unlike smartphones. You just need to press the Push-to-Talk (PTT) button, and the recipient will respond instantly. Such real-time interaction is very efficient, and not having to dial numbers or scroll through your contact list saves time.

Durability

Another benefit of using jobsite communication radios is that they are quite durable and rugged compared to smartphones. Radio units are built to military-grade specifications with various IP ratings, which makes them ideal for facing all the construction wear and tear. Some of the key durability features you will find include:

• Impact resistance – falls and drops are unavoidable construction side effects, and you will definitely drop something you are holding in your hand as you move around the unpredictable jobsite. If it is a smartphone, our thoughts are with you! If it is a radio unit, well, you are good to go!
• Dust and water resistance – communication radios are designed to withstand exposure to aggressive construction elements like dust and water. Since you will be using them every now and then, chances are that they will be exposed to rain or gather dust over time. The overall design keeps the unit safe from such damages and allows the radio to last longer.
• Mold resistance – another key durability feature is mold resistance through antimicrobial coatings. Radio units that include such an outer coating stay resistant to mold development, which is great if you are mostly working in moisture-prone jobsites.

Portability

Jobsite communication radios are handheld units, so they are very portable to carry around. Even with all the durability features mentioned above, these units are quite lightweight. They enable hands-free convenience as well if they come with a belt clip that lets you secure the unit to your belt, shirt, or pocket. You can then use a headset or microphone to communicate with the recipients. This is particularly useful if you are standing on a ladder or have your hands full. You will recharge the radio unit overnight when it is not in use, and it will be ready for jobsite portability for the whole day.

Sound clarity

Sound clarity is another reason why you cannot rely on smartphones for jobsite communication. The signal reach can be annoyingly slow, not to mention heavily distorted with all the background construction noise. Two-way radio units are built to address signal coverage and sound clarity, allowing you to communicate with a crisp and clear voice. Most radios are equipped with noise suppression technologies that muffle background noise, which makes your voice more audible over all the surrounding disturbance. They also offer multiple communication channels that help you allocate each one to a different jobsite recipient, effectively distributing your communication traffic and preventing sound interference. In addition, jobsite walkie-talkies feature a power output of 3-5 watts for the perfect signal delivery within the required range.

The 2 main radio frequencies used by these radios are Very High Frequency (VHF) and Ultra High Frequency (UHF). If you are working in a natural open field with a clear line of sight, you might want to use VHF communication radio units as they work best in such open areas. UHF radios are more suitable for urban jobsites that are crowded with buildings and similar obstacles, so there is no proper line of sight that can connect any 2 communication points.

These UHF signals can go through walls and other obstructions, establishing a clear and loud communication link between workers.

Jobsite safety

The next major benefit offered by jobsite communication radios is a range of safety features designed to keep workers safe through alerts. Here are some of the best safety aspects you will find in any two-way construction radio unit:

• NOAA weather channel alerts to alert workers of incoming storms and other challenges.
• Lone worker alerts for the safety of anyone working alone in tough and hazardous jobsites.
• A text messaging feature in case the radio does not work.
• Built-in emergency alarms that alert others to you if you are in danger.
• GPS tracking to monitor the jobsite workforce so that no one misses a notification during emergencies.
• Man Down alerts that rely on the accelerometer’s position to determine if a worker has collapsed or is not moving for some time. This alerts managers or safety personnel immediately and is an important safety consideration for people with medical conditions.
• Transmit Interruption that allows safety and management teams to interrupt all communications and transmit emergency messages that everyone will be able to receive.

Long battery life

Lastly, jobsite communication radios have long-lasting batteries that can stretch for an entire workday. A single charge is enough to give you continuous usage of around 15 hours and a general duration of 1-2 days depending on how frequently you use the unit. This is also why smartphones are not suitable for jobsite communication, as they are used for multiple other purposes and have battery-draining apps. Since a two-way radio works as a dedicated communication unit, it is the ideal tool for just sending and receiving alerts, which extends the battery life as well.

Popular jobsite communication radios

Before discussing the products, we want to share a key reminder in terms of a radio’s stated coverage. Usually, radio units are advertised to provide a signal coverage of around 30 miles, for example.

This range is actually the best-case scenario for open, outdoor fields with a visible line of sight between any two points. There are no buildings to obstruct the view, but there could be trees and rocks here and there. So, the given radio will be able to cover this range easily. However, if there are obstacles in the middle, you will find the coverage drop to nearly half the actual distance – which is why you need to consider VHF and UHF.

Here are some of the best two-way communication radios with jobsite-ready features that you should look for before buying a radio unit. If you want to know which features make a good jobsite walkie-talkie, the following list will be a simple buying guide for what to expect. It will also help you understand why you should only opt for jobsite radio units and not rely on smartphones or ordinary business radios for construction communications.

Walk the walk and talk the talk with a construction walkie-talkie

Two-way communication radios are essential tools for any construction environment. They have a huge communication and safety element that keeps conversations flowing through a jobsite, which is critical for the workforce. Communication delays or a complete failure to communicate can both cause confusion, errors, milestone misunderstandings, and accidents. This will cause teams to redo everything in order to reverse the damage, which is very inefficient and makes a costly mistake to pay for. Jobsite communication radios help crews stay in touch regardless of where they are working. They enable clear transmissions and come with a range of impressive jobsite-ready features like those discussed above. These radio units are specifically built to survive the ever-changing construction world, so even though smartphones save the day for various other reasons, they have to take the back seat for now and watch how it’s done!
