How many two-way radios do you need for an event?

Short answer: count radios by role, not by headcount. Give a radio to everyone who has to make or receive a decision during the event, such as duty managers, security, production, parking, first aid, guest services and the control desk. Then add spares for swaps and late changes. Most event radio plans go wrong on channels and charging, not on the number of radios.

Step 1: list roles, not people

Start from the run sheet, not the staff list. Volunteers handing out wristbands rarely need a radio. Their team lead does. A simple test: if this person cannot be reached for ten minutes, does something go wrong? If yes, they get a radio.

Roles that usually need one:

• Event director and duty managers

• Security leads and posts at entrances and exits

• Stage, production and AV

• Parking and traffic

• First aid and medical

• Box office, accreditation and guest services

• Vendor and site operations leads

• Facilities, cleaning and power

• The control desk

Then add spares. Radios get left in vans, dropped, or handed to someone who arrived late. Send us your role list and we will suggest a spare count for your size of event.

Step 2: plan channels before radios

A radio count without a channel plan is how one busy channel ends up carrying security, parking and catering at once. Give each team its own channel, add a command channel for leads, and keep one all-call channel where only managers can talk. Zello has no channel cap, so you can split teams as finely as the event needs.

Name channels the way people talk on site: “Gate A”, “Main stage”, “Car park”. We label radios to your team or zone names before they ship.

Step 3: check coverage at the venue

Traditional rental radios depend on range between handsets, and large or spread-out sites often need a temporary repeater. Our rental radios run Zello over cellular and Wi-Fi, so there is no repeater to set up and a multi-venue event is no harder to cover than one building.

Coverage still depends on the signal at your venue. We check the specific site before we confirm a rental, and for indoor halls we can put radios on the venue Wi-Fi. Large crowds can put heavy load on local cellular networks, so for big events we also plan around the venue Wi-Fi.

Step 4: plan charging and swaps

A radio that dies at 9 pm is worse than no radio. Set up a charging station at the control desk, decide when radios swap, and track who has which unit. Ask for the rated battery capacity of each model and compare it with your longest shift. Our rentals ship with chargers and standard accessories.

Step 5: choose radios and accessories by role

• Stewards and volunteers: the screen-free Inrico T522A, one button and nothing to get wrong.

• Staff working across several channels: the Inrico T640A, which has a display.

• Event managers: the Inrico S380 with an earpiece.

• Security and front of house: earpieces, so radio traffic stays discreet near guests.

• Stages and loading docks: speaker mics for noisy areas.

Step 6: set up the control desk

The control desk should see and reach everyone. A Zello Dispatch Hub seat on a laptop gives the desk push-to-talk on every channel and a map of where radios are. We add it to rentals on request.

When to book

As early as you can for large events. Quantities for peak weekends are finite, and we configure every radio against your event plan before it leaves us, which takes lead time. Send us your dates, quantity and venue and we will confirm what is practical.

Rent or subscribe?

If you run one event a year, rent. If you run events every month, or your venue hosts them all year, an ongoing account is often simpler. Managed Zello is month to month with no minimum, from $24.95 per user per month on Core. Many customers rent first to prove coverage and channel design, then move across. Venues should also look at our hospitality page.

Frequently asked questions

How many radios per staff member does an event need?

There is no fixed ratio that fits every event. Count the roles that must be reachable, give each one a radio, then add spares. A festival with many entry points needs more radios per staff member than a conference in one hall.

How many channels should an event use?

One for each team that works independently, plus a command channel for leads and an all-call channel for announcements. Zello does not cap channels, so teams do not have to share.

Do we need an FCC license to use rental radios at an event?

Not for our Zello radios, which run over cellular and Wi-Fi. Licensed UHF and VHF rental radios are different. Our FCC licensing guide explains when a license applies.

What if the venue has poor cell signal?

We check coverage against the specific venue before confirming a rental. Indoors, radios can use the venue Wi-Fi. If a site cannot be covered well, we tell you before you rent.

Can we add radios during the event?

Where stock allows, yes. Extra radios are signed in to the same Zello channels and sent to site.
