Logistics radio systems for warehouses, docks and yards: 15–40 radios, 4–6 talk groups, UHF coverage and forklift accessories for 10,000 m² sites.

Quick answer
A logistics radio system is a traffic-control system. In one shift, the gate, yard, loading dock, picking floor and transport office generate a continuous stream of short calls. If one link is missing, trailers queue and orders slip.
The radio environment is hostile in a way that is invisible on a floor plan: racking, containers, steel cladding and stock absorb and reflect signal. A site that looks open on a drawing can be full of dead spots in the aisles that matter most.
| Zone / role | Typical users | Radio & accessory | Talk group | Example quantity |
|---|---|---|---|---|
| Receiving / inbound | 4–10 | DMR handheld + speaker mic | Inbound | 8 |
| Picking / put-away | 10–30 | Compact DMR handheld + earpiece | Floor groups | 20 |
| Loading dock | 4–10 | DMR handheld + speaker mic | Outbound | 8 |
| Yard / forklift | 5–15 | Vehicle radio or PoC terminal | Yard | 10 |
| Security / gate | 3–6 | DMR handheld + base station | Security | 4 |
| Inventory / returns | 2–6 | Compact DMR handheld | Inventory | 4 |
Example for a 10,000 m² distribution centre. Add 10–20% spares and a charging rack per department.
| Item | Typical specification | Why it matters |
|---|---|---|
| Band | UHF 400–470 MHz | Better penetration around racking and steel |
| Power | 4–5 W handheld; 25–50 W mobile | Licensed repeater coverage and yard reach |
| Protection | IP54–IP67 | Dust, cold-store condensation and washdown |
| Battery | 12–18 h, hot-swap optional | Covers a full shift and overtime |
| Audio | Loud speaker, noise-cancelling mic | Audible over conveyors, forklifts and dock noise |
| Accessories | Speaker mic, earpiece, vehicle kit | Hands-free for drivers and pickers |
| Dimension | Analog | DMR | PoC |
|---|---|---|---|
| Talk groups | One per frequency | Two per 12.5 kHz carrier | Platform groups |
| Racking coverage | Repeater + aisle antennas | Repeater + aisle antennas | Depends on indoor mobile signal |
| Forklift integration | Vehicle radio | Vehicle radio or handheld | Vehicle terminal |
| Recording / dispatch | Limited | Integrated | Platform-dependent |
| Best fit | Small single-site warehouse | Multi-zone distribution centre | Multi-site fleet |
A 10,000 m² distribution centre typically needs 15–40 radios across receiving, picking, dock, yard, security and inventory. A larger automation-heavy site can need 50 or more; a small single-aisle warehouse may need 8–15.
Count by zone and shift, then add 10–20% spares. The yard and dock usually need louder audio and vehicle accessories; the picking floor needs compact radios with long battery life.
Metal racking, containers, steel cladding and dense stock absorb and reflect radio energy. The result is not a uniform reduction in range; it is a patchwork of dead spots that changes when the stock changes. A radio that works in an empty aisle can fail when the aisle is full.
The fix is not more power alone. It is antenna placement: a repeater on the roof or a lighting mast, plus indoor antennas positioned to illuminate the aisles rather than the ceiling. A walk test along every aisle is the only way to prove coverage.
The yard and dock are a different radio problem from the aisles: fewer obstructions but longer distances, vehicle bodies, containers and changing trailer positions. A repeater on a high point of the warehouse or a yard mast usually covers both, but the antenna pattern has to be planned for the yard.
Forklift and truck operators are often in a cab with the radio on a charger. A vehicle set with an external antenna and a speaker microphone is more reliable than a handheld left on the seat.
Follow the flow of goods: inbound, put-away/picking, outbound, yard, returns and security. Add a management or control group that can reach all of them, and one emergency group that overrides normal traffic.
On DMR, two talk groups can share a 12.5 kHz carrier. That keeps the licence simple, but do not put two groups that peak at the same time on one carrier.
A vehicle-mounted radio with an external antenna, a speaker microphone and a hands-free PTT is the most reliable setup for a forklift. If the driver also walks the floor, a belt-worn handheld with a remote speaker mic is a practical compromise.
Avoid leaving a handheld on the seat or in a cup holder. Vibration, impacts and heat shorten its life, and the antenna is shielded by the cab.
Use a charging rack per department, issue radios by number and keep a master programming file. Label each radio with its zone and group. For a multi-shift operation, a simple sign-out sheet is enough; for a large site, a management platform can track battery health and disable a lost unit.
Plan battery rotation: two packs per radio, dated and replaced on schedule. A radio with a tired battery is worse than no radio, because the user believes it will work.
Logistics radio compliance covers the licence, the physical environment and the safety of drivers and pedestrians. Settle the frequency plan before the racking is full, because coverage testing is harder once the stock arrives.

The control room can reach any building; teams move between areas without changing channel; the system extends as new buildings are added.

A 10,000 m² distribution centre typically needs 15–40 radios. Count by zone and shift, add 10–20% spares, and include vehicle radios for forklifts and yard tractors.
Metal racking, stock and steel cladding absorb and reflect the signal. A radio that works in an empty aisle can fail when the aisle is full. A repeater with aisle-facing antennas and a walk test is the fix.
UHF 400–470 MHz is the usual choice for indoor racking and buildings. VHF can work in open yards and along linear sites, but it is less reliable in dense racking.
A small warehouse can use licence-free PMR446 or FRS handhelds within the limits. A large site with a repeater, multiple talk groups or yard coverage normally needs a business licence.
Use a repeater on a high point of the warehouse or a yard mast, with antennas planned for the yard and dock. Vehicle sets with external antennas are more reliable than handhelds left in a cab.
Start with inbound, picking, outbound, yard, returns and security. Add a management group and an emergency group. On DMR, two groups can share a carrier if their peak traffic does not overlap.
Use a charging rack per department, issue by number and keep a sign-out sheet. Plan two battery packs per radio and replace them on a schedule.
