Mining and quarry operations are among the most demanding environments for professional communication.

Workers may be spread across:

• Open-pit mines
• Quarry faces
• Crushing and screening areas
• Loading zones
• Haul roads
• Workshops
• Stockyards
• Remote site offices
• Underground sections
• Heavy-equipment operating areas

At the same time, excavators, dump trucks, crushers, drilling equipment and other heavy machinery may be operating continuously.

In this kind of environment, communication delays can affect much more than productivity.

Teams may need to communicate immediately about:

• Vehicle movement
• Equipment breakdowns
• Blasting-related coordination
• Safety incidents
• Production changes
• Loading operations
• Maintenance requirements
• Route obstructions
• Emergency situations

Mobile phones can support some administrative communication, but they are not always the most practical tool for fast operational coordination.

A properly designed two-way radio system for mining and quarry operations provides immediate push-to-talk communication between teams without requiring employees to make individual phone calls.

This guide explains what Indian mining and quarry businesses should consider when selecting walkie-talkies, including coverage, ruggedness, VHF vs UHF, repeaters, digital radio, battery life, safety features, licensing and specialised requirements for hazardous mining environments.

Why Mining Operations Need Reliable Radio Communication

Mining sites are often geographically large and operationally complex.

A single site may include:

• Excavation areas
• Crushing plants
• Workshops
• Loading zones
• Dispatch areas
• Administrative buildings
• Weighbridges
• Haul roads
• Remote stockpiles

Teams operating in these areas must coordinate constantly.

For example, a dump-truck driver may need to communicate with:

• Excavator operator
• Dispatch controller
• Site supervisor
• Maintenance team
• Traffic coordinator

Using individual telephone calls for every interaction would be inefficient.

With a two-way radio, the user can simply press the push-to-talk button and speak to the appropriate group.

That speed is one of the main reasons professional radio systems remain important in mining.

---

Mining Communication Is Different From Normal Business Communication

A hotel, office or retail store may only need communication across a few floors.

A mining operation presents a completely different RF environment.

Radio signals may need to work around:

• Deep excavation areas
• Rocky terrain
• High quarry walls
• Heavy machinery
• Conveyors
• Steel structures
• Crushers
• Workshops
• Remote haul roads

This means businesses should not select mining radios simply by asking:

“Which walkie-talkie has the longest advertised range?”

The better question is:

“Which communication system will provide reliable coverage across our actual site?”

---

Walkie-Talkie Range in Mines and Quarries

There is no single guaranteed walkie-talkie range for a mining site.

Actual performance depends on:

• Radio frequency
• RF output
• Antenna
• Terrain
• Elevation
• Quarry depth
• Rock formations
• Equipment
• Buildings
• Repeater placement

An open haul road with clear line of sight may provide excellent coverage.

A worker standing behind a quarry wall or deep inside an excavation may experience much weaker communication.

This is why a radio site survey can be more valuable than simply purchasing higher-powered radios.

---

Open-Pit Mines vs Underground Mines

Radio requirements can change dramatically depending on the type of mining operation.

Open-Pit Mining

Typical challenges include:

• Large geographic areas
• Elevation differences
• Haul roads
• High quarry walls
• Heavy equipment
• Remote work zones

Conventional professional VHF or UHF radio systems, often supported by repeaters, may work well when properly designed.

Underground Mining

Underground environments are considerably more complicated.

Rock and tunnel geometry can prevent ordinary radio signals from travelling effectively through the mine.

Underground communication may require specialised infrastructure such as:

• Approved wireless communication systems
• Distributed antennas
• Leaky-feeder systems
• Dedicated underground repeaters
• Tracking and communication networks

DGMS maintains approval frameworks and lists of specialised electrical and wireless equipment intended for use in mines, including approved digital wireless and miner-tracking systems. (DGMS)

Therefore, a solution suitable for an open quarry should not automatically be assumed suitable for underground mining.

---

VHF vs UHF Walkie-Talkies for Mining

One of the first decisions when designing a mining radio system is choosing the appropriate frequency band.

Professional radios commonly operate in either:

• VHF
• UHF

Neither band is universally better.

The correct choice depends on the environment.

---

VHF Radios

VHF generally performs well across:

• Open terrain
• Rural environments
• Long outdoor paths
• Large open sites

This can make VHF attractive for:

• Open-pit mines
• Quarry operations
• Long haul roads
• Surface mining
• Remote outdoor sites

Where there are fewer large structures blocking the signal, VHF can provide excellent outdoor performance.

---

UHF Radios

UHF can often perform better around:

• Buildings
• Industrial structures
• Machinery
• Dense operational areas

It may therefore be suitable for:

• Processing plants
• Workshops
• Warehouses
• Crushing facilities
• Built-up industrial areas

A large mining organisation may even use different communication approaches for different parts of the site.

---

Do Mining Sites Need Repeaters?

Often, yes.

A radio repeater receives a transmission and retransmits it from a strategically positioned location.

This can significantly improve coverage across difficult terrain.

Consider an open-pit mine.

Workers at the bottom of the pit may not have direct line of sight to employees on the opposite side.

A repeater located at a suitable elevated position can help connect those areas.

Repeaters are particularly useful when:

• Quarry walls block communication
• The site covers a large area
• Haul roads extend far from the main facility
• Workers operate at different elevations
• Buildings or terrain create radio dead zones

A well-positioned repeater can often improve coverage more effectively than simply increasing handheld radio power.

---

Repeater Placement Matters

Installing a repeater does not automatically solve every coverage problem.

Its performance depends heavily on:

• Height
• Antenna position
• Terrain
• Feed-line quality
• Frequency planning
• RF interference

A repeater positioned poorly may provide disappointing results.

A professionally designed mining communication system should therefore consider the site’s physical geography.

---

Analog vs Digital Radios for Mining

Mining companies can choose between:

• Analog radio
• Digital radio
• Hybrid systems supporting both

For many modern professional operations, digital radio can provide significant advantages.

---

Advantages of Digital Radio

Digital systems such as DMR may provide:

• Clear usable audio
• Better spectrum efficiency
• Group calls
• Individual calls
• Caller identification
• Emergency functions
• Text or data capability on supported models
• GPS/GNSS on selected radios
• Better fleet management options

Digital systems can also allow businesses to create separate communication groups for different departments.

For example:

Channel / Talk Group 1

Production

Channel / Talk Group 2

Maintenance

Channel / Talk Group 3

Security

Channel / Talk Group 4

Dispatch

Channel / Talk Group 5

Emergency

This keeps routine traffic organised.

---

Digital Radio Does Not Automatically Mean Longer Range

One common misconception is:

Digital radio always has more range than analog.

That is not necessarily true.

Coverage still depends on:

• Frequency
• Antenna
• Terrain
• Power
• Repeater design

Digital radio can often maintain clearer audio close to the edge of usable coverage.

But once the digital signal becomes too weak, communication can disappear rapidly.

Therefore, digital technology should not replace proper coverage planning.

---

Important Features for Mining Walkie-Talkies

A radio designed for office use may not survive long in a mining environment.

Mining businesses should evaluate several key features.

---

1. Rugged Construction

Mining radios may encounter:

• Dust
• Mud
• Vibration
• Rain
• Frequent handling
• Equipment cabins
• Accidental drops

The radio housing should therefore be designed for professional industrial use.

A cheap consumer radio may function initially but become expensive if equipment repeatedly needs replacement.

---

2. IP Rating

IP ratings indicate protection against dust and water ingress.

Common professional-radio ratings include:

• IP54
• IP55
• IP67
• IP68

For dusty quarry or mining environments, higher dust protection can be particularly valuable.

However, remember:

An IP67 or IP68 radio is not automatically approved for use in explosive or hazardous mining atmospheres.

Ingress protection and intrinsic safety are entirely different requirements.

---

3. Loud Audio

Mining sites can be extremely noisy.

Workers may be operating close to:

• Excavators
• Dump trucks
• Crushers
• Generators
• Drilling equipment
• Conveyors

A radio that sounds excellent in an office may be difficult to hear beside heavy equipment.

Buyers should evaluate:

• Speaker volume
• Audio clarity
• Noise suppression
• Microphone performance

before selecting radios for field workers.

---

4. Noise-Cancelling Technology

Some modern digital radios offer advanced noise suppression.

This can help reduce background noise from:

• Machinery
• Engines
• Wind
• Industrial equipment

For mining users, audio processing can sometimes be more valuable than additional display features.

The ability to understand a message clearly the first time improves both productivity and safety.

---

5. Long Battery Life

Mining shifts may run:

• 8 hours
• 10 hours
• 12 hours
• Longer during special operations

Workers may also be far from charging stations.

Therefore, battery runtime should comfortably exceed expected shift duration.

A good deployment may include:

• High-capacity batteries
• Spare batteries
• Multi-unit chargers
• Central charging stations

Battery planning becomes especially important for critical employees such as supervisors and dispatch personnel.

---

6. Emergency Button

Professional radios may include a programmable emergency button.

In an emergency, the worker can quickly trigger an alert to:

• Dispatch
• Supervisor
• Control room
• Emergency response team

This can be faster than trying to navigate menus or make a phone call.

Emergency features should be configured and tested as part of the communication system.

---

7. Lone Worker

Some professional radio systems include a lone-worker feature.

This can be useful for employees working:

• In isolated areas
• During inspections
• At remote equipment
• On night shifts

The system may require the user to periodically confirm their status.

If the confirmation is not received, an alert can be generated.

The exact behaviour varies by radio platform.

---

8. Man Down

Selected professional radios can support man-down functionality.

Depending on the implementation, the radio can detect unusual orientation or lack of movement and trigger an alert.

This may be useful for certain mining roles.

However, it should be treated as an additional safety feature—not as a replacement for proper working procedures.

---

9. GPS / GNSS

Some digital radios include location capability.

This can allow control-room or dispatch personnel to identify where compatible radios are located.

Potential applications include:

• Vehicle supervision
• Worker coordination
• Emergency response
• Remote-site management

Location features can be particularly useful on large mining properties.

---

10. Display vs Non-Display Radios

Not every mining employee needs a display.

Non-Display Radio

Advantages:

• Simple
• Durable
• Easy to operate
• Fewer distractions

Suitable for many frontline workers.

Display Radio

Can be useful for:

• Supervisors
• Dispatch teams
• Maintenance leaders
• Users requiring contacts or messages

A mixed fleet can therefore make economic sense.

---

Radios for Heavy-Equipment Operators

Mining operators may spend most of their shift inside:

• Dump trucks
• Excavators
• Loaders
• Dozers

A handheld radio can work, but vehicle-based communication may sometimes be more practical.

Mobile radios installed in vehicles can provide:

• Higher usability
• Vehicle-mounted antennas
• Permanent power
• Better audio
• External speaker options

A mining communication system may therefore combine:

• Handheld radios
• Vehicle mobile radios
• Base stations
• Repeaters

instead of relying on handhelds alone.

---

Base Radios for Dispatch and Control Rooms

Control-room personnel may communicate with dozens of workers throughout the day.

A fixed or desktop radio setup can be more practical than a handheld.

Possible benefits include:

• Larger controls
• External microphone
• Better audio
• Permanent power
• External antenna

Mining dispatch communication should be designed around workflow rather than forcing every user to carry the same radio model.

---

Speaker Microphones for Mining Workers

A remote speaker microphone can be very useful for supervisors and field workers.

Instead of repeatedly removing the radio from a belt, the user can communicate through a microphone clipped close to the shoulder.

This can improve:

• Accessibility
• Speed
• Convenience

Heavy-duty speaker microphones should be selected according to the radio and environment.

---

Headsets and Hearing Protection

Some mining environments have high continuous noise levels.

Workers may already be required to wear hearing protection.

Compatible communication headsets can help integrate:

• Hearing protection
• Radio audio
• Microphone communication

This can be more practical than simply increasing radio speaker volume.

Compatibility and safety requirements should always be confirmed before deployment.

---

Communication for Haul Roads

Haul-road communication is one of the most important mining use cases.

Vehicles may include:

• Large dump trucks
• Water tankers
• Maintenance vehicles
• Excavators
• Loaders
• Light vehicles

Radio communication can help coordinate:

• Vehicle movement
• Road obstructions
• Loading
• Dispatch
• Breakdown response

A properly designed channel structure can help prevent unnecessary congestion.

For example, separate groups can be assigned for:

• Haul operations
• Loading
• Maintenance
• Emergency response

---

Walkie-Talkies for Quarry Operations

Quarries have many of the same communication challenges as mines but often operate across smaller defined sites.

Typical users may include:

• Excavator operators
• Crusher operators
• Loader operators
• Truck drivers
• Supervisors
• Maintenance teams
• Security staff

Reliable radios can help coordinate the movement of materials between:

• Quarry face
• Crushing area
• Screening plant
• Stockyard
• Loading point

This can reduce delays caused by workers trying to locate each other physically.

---

Communication Around Crushers and Processing Plants

Crushing plants can be extremely noisy.

Radio requirements may include:

• High audio output
• Noise suppression
• Speaker microphones
• Headsets

Coverage can also become more complicated because industrial machinery and metal structures may affect RF propagation.

Site testing is therefore important.

---

Communication During Maintenance

When large equipment breaks down, several teams may need to coordinate.

For example:

• Operator
• Maintenance technician
• Supervisor
• Spare-parts team
• Workshop
• Dispatch

Immediate radio communication can reduce the time spent trying to locate the right employee.

This can contribute to shorter equipment downtime.

---

Walkie-Talkies and Blasting Operations

Mining and quarry sites may conduct controlled blasting.

Communication surrounding blasting must follow strict operational and safety procedures.

Two-way radios may form part of a broader communication process used for authorised operational coordination, but they should never substitute for formal blasting procedures, warning systems or statutory safety requirements.

Radio configuration should also be assessed carefully in environments involving explosives.

Businesses should obtain guidance from qualified safety and mining professionals for these applications.

---

Intrinsically Safe Radios for Mining

This is one of the most important areas where buyers need to be careful.

Some mining environments may contain potentially explosive atmospheres.

In those environments, ordinary electrical or radio equipment may be unsuitable.

Intrinsically safe equipment is designed to limit electrical and thermal energy so that it does not become an ignition source under the conditions covered by its certification.

DGMS specifically addresses flameproof and intrinsically safe equipment for hazardous mine atmospheres, and its approval framework covers equipment intended for use in coal and metal mines. (DGMS)

Therefore:

Never assume that an ordinary rugged walkie-talkie is suitable for an underground coal mine or another hazardous mining area.

---

IP68 Does Not Mean Intrinsically Safe

This distinction deserves special attention.

A radio may be:

IP68

and still not be intrinsically safe.

IP68 concerns protection against dust and water ingress.

Intrinsic-safety certification concerns the equipment’s ability to operate in specified hazardous atmospheres without presenting an unacceptable ignition risk.

They solve completely different problems.

---

DGMS Approval and Mining Equipment

India’s Directorate General of Mines Safety maintains policies and published lists relating to equipment approved for mine use.

DGMS’s current approval framework exists because certain equipment used in mines must meet statutory safety requirements, and DGMS publishes approved equipment and manufacturers for relevant categories. (DGMS)

Mining businesses should therefore verify applicable DGMS requirements before deploying radios in regulated or hazardous mine environments.

This is especially important for:

• Underground coal mines
• Hazardous atmospheres
• Specialised underground communication systems

---

License-Free Walkie-Talkies for Mining

India permits certain low-power PMR446 equipment under licence-exempt conditions.

The applicable framework covers 446.0–446.2 MHz, with up to 500 mW ERP, and specifies handheld peer-to-peer use with an integral antenna rather than repeater or infrastructure operation. (Dot Government of India)

For a small quarry or limited local coordination, compliant low-power equipment may be useful in some cases.

However, large mines often require:

• Greater coverage
• Repeaters
• Dedicated frequencies
• Better system control
• More rugged professional equipment

In those environments, a properly designed licensed professional radio system may be more appropriate.

---

Walkie-Talkie Licensing in India for Mining Companies

Professional radio systems using licensed spectrum need to be deployed within India’s current Department of Telecommunications/WPC framework.

India transitioned to new telecommunications authorisation rules in 2026, and the DoT’s Authorisation Portal now handles relevant authorisations, including the new Radio Equipment Possession Authorisation framework. (Department of Telecom eServices)

The DoT also maintains a service for licensing short-range UHF handheld radio networks such as walkie-talkies. (Department of Telecom eServices)

Because the regulatory framework has changed recently, businesses should verify the current authorisation, spectrum and equipment requirements at the time of deployment rather than relying on older licensing terminology.

---

PoC Radios for Mining Operations

PoC stands for:

Push-to-Talk over Cellular

These devices use:

• 4G
• LTE
• Wi-Fi
• Internet connectivity

PoC can be attractive for companies operating across:

• Several mines
• Multiple offices
• Remote management locations
• Regional logistics networks

A manager in one city could potentially communicate with teams at another site through a broadband PTT platform.

However, PoC has one major dependency:

Network availability.

Remote mines may have limited or unreliable cellular coverage.

For critical local operational communication, a conventional radio network may therefore remain preferable.

---

Hybrid Communication Systems

Large mining organisations do not necessarily need to choose only one communication technology.

A hybrid system could use:

DMR Radios

For workers operating locally across the mine.

Vehicle Radios

For haul trucks and heavy equipment.

Repeaters

For extending site coverage.

PoC

For regional management and multi-site communication.

Specialised Underground Systems

Where normal surface radio cannot provide suitable underground communication.

This role-based approach often produces a stronger overall communication system.

---

Why Mobile Phones Alone May Not Be Enough

Mobile phones are extremely useful, but they have disadvantages for operational mining communication.

A phone call usually requires:

1. Unlocking the device.
2. Finding the contact.
3. Calling the person.
4. Waiting for them to answer.
5. Repeating the message to others if needed.

Two-way radio communication can be:

Press → Speak → Group hears message

This makes radio particularly effective for short operational instructions.

Phones can still complement the system for:

• Documents
• Photos
• Emails
• Administrative calls
• Non-urgent communication

---

Channel Planning for Mining Sites

Poor channel planning can make even excellent radios frustrating to use.

If every department communicates on one channel, users may hear constant unnecessary traffic.

A better structure might include:

Talk Group 1

Production

Talk Group 2

Haulage

Talk Group 3

Maintenance

Talk Group 4

Security

Talk Group 5

Supervisors

Talk Group 6

Emergency

This allows communication to remain relevant to the user.

Supervisors can have access to several groups if required.

---

Radio Discipline Matters

Technology alone does not create good communication.

Employees should also receive simple radio training.

Good practices include:

• Identify yourself when required
• Keep messages short
• Speak clearly
• Avoid unnecessary conversation
• Wait briefly after pressing PTT
• Repeat critical information when necessary
• Keep emergency channels clear

Radio discipline becomes increasingly important as the number of users grows.

---

Site Surveys Before Deployment

For large mining sites, it is strongly advisable to test coverage before finalising the system.

A site survey can identify:

• Dead zones
• Weak coverage areas
• Repeater requirements
• Antenna locations
• Frequency suitability

Testing should include realistic working locations such as:

• Pit bottom
• Quarry face
• Crusher
• Workshop
• Haul road
• Stockyard
• Site office

Coverage should be designed around where workers actually operate.

---

Don’t Judge Mining Radios by Advertised Range

Claims such as:

• 5 km
• 10 km
• 20 km

should be treated cautiously.

Range varies dramatically with terrain.

A radio that communicates many kilometres across flat open terrain may struggle across a much shorter distance when a quarry wall blocks the signal.

System design matters more than marketing range numbers.

---

How Many Radios Does a Mining Site Need?

The answer depends on operational roles rather than simply employee count.

Potential radio users include:

• Shift supervisor
• Mining supervisor
• Excavator operators
• Dump-truck coordinators
• Maintenance teams
• Crusher operators
• Security
• Dispatch
• Safety staff

Some organisations may use shared radios between shifts.

Others may permanently assign radios to specific employees or vehicles.

A spare pool should also be considered.

---

Spare Radios Are Important

Mining equipment works in harsh environments.

Even rugged radios can eventually suffer:

• Drop damage
• Battery failure
• Antenna damage
• Accessory failure

Keeping several spare radios available prevents a damaged handset from immediately affecting operations.

---

Central Charging for Mining Fleets

Larger mining operations should consider a central radio charging area.

This can include:

• Multi-unit chargers
• Spare batteries
• Numbered radio positions
• Equipment check-out system

At shift change, outgoing employees return their radios and incoming employees receive fully charged equipment.

This makes radio availability easier to manage.

---

Choosing the Right Mining Radio Supplier

Mining communication is more complex than purchasing a box of walkie-talkies.

A professional supplier should be able to discuss:

• VHF vs UHF
• Coverage
• Repeaters
• Digital radio
• Vehicle radios
• Base stations
• Batteries
• Accessories
• Frequency planning
• Licensing
• Mining-specific equipment requirements
• After-sales service

If the entire recommendation is based only on advertised kilometre range, the solution is probably incomplete.

---

---

Common Mistakes When Buying Walkie-Talkies for Mining

Mistake 1: Buying Based Only on Range Claims

Mining terrain can radically change radio coverage.

Mistake 2: Assuming More Power Solves Everything

Repeater location and antenna design may matter more.

Mistake 3: Ignoring VHF vs UHF

The environment should determine the frequency strategy.

Mistake 4: Using Ordinary Radios in Hazardous Areas

Specialised certified or approved equipment may be required.

Mistake 5: Confusing IP Rating With Intrinsic Safety

They are completely different specifications.

Mistake 6: Ignoring Vehicle Radios

Heavy-equipment operators may benefit from permanently installed radios.

Mistake 7: Failing to Conduct a Site Survey

Coverage should be tested in real working locations.

Mistake 8: Buying Too Few Batteries

Long shifts require sufficient battery reserve.

Mistake 9: Putting Everyone on One Channel

Good channel planning reduces unnecessary traffic.

Mistake 10: Ignoring After-Sales Support

Large radio fleets require ongoing batteries, accessories, programming and maintenance.

Frequently Asked Questions

What is the best walkie-talkie for mining?

There is no single best radio for every mine. The correct solution depends on whether the site is open-pit or underground, terrain, coverage, noise, hazardous-area requirements and the number of users.

Is VHF or UHF better for mining?

VHF can be effective across large open outdoor areas, while UHF may perform better around industrial structures and buildings. A site survey is the best way to determine the appropriate system.

How far can mining walkie-talkies reach?

There is no guaranteed distance. Range depends on terrain, quarry depth, antennas, frequency and repeater infrastructure.

Do mines need repeaters?

Large mines and quarries often benefit from repeaters, particularly where terrain or excavation walls create dead zones.

Are digital radios better for mining?

Digital radios can provide clearer usable audio, talk groups, emergency functions and data features. Whether they are appropriate depends on the site’s requirements.

Can DMR radios be used in mines?

DMR can be suitable for many surface mining applications. Hazardous or underground environments may require specifically approved equipment and specialised system design.

Can an IP68 walkie-talkie be used underground?

Not simply because it is IP68. IP ratings relate to dust and water resistance. Hazardous mining environments may require appropriate intrinsic-safety or DGMS approvals.

What is an intrinsically safe walkie-talkie?

It is radio equipment designed and certified so that its electrical and thermal energy remains within specified limits for use in particular hazardous environments.

Do walkie-talkies need a licence in India?

Some specific low-power equipment can operate under licence-exempt conditions, while professional licensed radio systems require applicable DoT/WPC authorisations. The exact requirement depends on the equipment and spectrum being used. (Dot Government of India)

Can license-free walkie-talkies be used at a quarry?

Compliant licence-exempt radios may work for limited local requirements, but their lower power and restriction against repeater infrastructure can make them unsuitable for larger mining sites. (Dot Government of India)

Can PoC radios be used in mines?

Yes, where suitable cellular or Wi-Fi connectivity exists. Remote sites with poor mobile coverage may require a conventional radio system for dependable local communication.

Are mobile phones enough for mining operations?

Phones are useful for administrative communication, but two-way radios provide faster one-to-many push-to-talk communication for operational teams.

What accessories are useful for mine workers?

Common accessories include rugged speaker microphones, spare batteries, multi-unit chargers, secure carrying solutions and suitable noise-reducing headsets.

---

Conclusion

Mining and quarry communication is not simply about purchasing the most powerful walkie-talkie available.

The complete communication system must be designed around:

• Terrain
• Site size
• Working environment
• Worker roles
• Heavy equipment
• Safety requirements
• Shift length
• Coverage expectations

For many open-pit mines and quarries, a professional VHF or UHF digital radio system supported by strategically placed repeaters can provide dependable communication across operational teams.

Larger operations may also benefit from:

• Vehicle-mounted radios
• Dispatch stations
• GPS-enabled radios
• Emergency functions
• Multi-unit charging
• PoC connectivity for management

Underground or hazardous environments require considerably more care.

Ordinary rugged radios should never be assumed suitable simply because they have a high IP rating. DGMS requirements, intrinsic-safety considerations and specialised underground communication infrastructure may apply. (DGMS)

The best approach is therefore to design the system around the mine rather than attempting to make one generic radio configuration work everywhere.

Electrosonic Technologies can help mining and quarry businesses evaluate professional two-way radio systems, repeaters, accessories and supporting communication infrastructure based on site size, terrain, operational requirements and applicable Indian regulatory requirements.
