What Is a Trunked Radio System, and Do You Need One?

Companies that rely on two-way radios for instant communication can sometimes scale so quickly that they experience difficulty maintaining their radio networks. Large numbers of users can overwhelm a conventional network’s bandwidth, and workers can be easily distracted by transmissions that aren’t relevant to them. That’s where a trunked radio system can serve them best. Learn more about what it is, and how to decide if one is appropriate for your team.

What Is a Trunked Radio System?

A trunked system differs from a traditional two-way radio network in that it utilizes dynamic channel selection to assign users based on groups. For example, let’s say that you have three teams, all of which operate independently of each other. In a trunked radio system, each team would already be designated as a group, so that when system users turn their radios on, they’re automatically connected with the appropriate user group on a randomly assigned channel. Once their communication ends, that channel becomes available again.

Why is this setup important? For starters, it reduces the risk for crosstalk with other radio users. Second, it adds a layer of security. With conventional radio systems, anyone can select a channel and hear what’s being transmitted. Trunked networks automate channel selection so that users can’t eavesdrop, and adds a layer of safety to mission-critical operations.

Does this mean that radio users no longer have access to all members of their company? Not necessarily. A dedicated channel that is accessible to your entire network can still be made available. It would be static rather than dynamic, so that all users would know what channel to turn to when they need the widest possible broadcast.

If you think a trunked radio system is right for you, RCA offers two-way radios that are compatible. They include the RDR7x50 series of handhelds, and the RDR5550 mobile.

This series includes the standard, non-display RDR7350, as well as the upgraded RDR7550 that boasts a two-inch, full-color screen and keypad. 

Both handheld two-way radios are designed with heavy-duty, military-grade chassis that meet the requirements for IP67 dust- and waterproof protection. They can also communicate with other digital or analog radios — even those from other brands!

The RDR7350 and RDR7550 are ideal for large companies in industries like manufacturing, construction, facility management, and security, as well as entertainment venues like hotels, resorts, and casinos.

If you have a lot of workers who spend time in vehicles, the RDR5550 is the perfect trunk-compatible mobile radio. Its benefits are similar to the handhelds above, while including advanced features like GPS location tracking for worker safety, and noise reduction in high-ambient environments.

Similar to other mobile two-way radios, RDR5550s are not barred from use in commercial vehicles like cellphones, making them the ideal choice for employees on the go.
