“How many kilometres will this walkie-talkie cover?”

It sounds like a simple question.

It is also one of the most difficult questions to answer accurately when buying a professional two-way radio.

Online marketplaces frequently advertise radios with claims such as:

• 3 km range
• 5 km range
• 10 km range
• 15 km range
• 20 km range

The problem is that a walkie-talkie does not have one fixed range.

A radio that communicates over several kilometres across an open field may struggle across a few hundred metres inside a reinforced concrete building.

A radio that performs well from the ground floor to the fourth floor may lose communication when one user enters the basement.

A system that works perfectly in an empty warehouse may behave differently after thousands of metal racks and pallets are installed.

That is why professional radio users should stop thinking of range as a number printed on a box.

A much better way to think about it is:

Walkie-talkie range is the result of the entire communication environment—not simply the radio model.

This guide explains what actually determines walkie-talkie range, why advertised kilometre figures can be misleading, what businesses should expect in different environments and how to improve radio coverage when direct communication is not enough.

---

So, How Far Can a Walkie-Talkie Really Reach?

The shortest accurate answer is:

Anywhere from a relatively short distance inside a difficult building to several kilometres or more in favourable open conditions, depending on the equipment and environment.

Motorola Solutions similarly notes that two-way radio range is affected by factors including:

• Radio power
• Frequency
• Terrain
• Building materials
• Weather
• Repeaters

and that communication over several miles may be possible in open environments while indoor or urban performance is often substantially shorter.

This is why two radios with similar specifications can produce completely different results at two different sites.

The radio matters.

But the environment often matters even more.

---

Why Advertised Walkie-Talkie Range Can Be Misleading

Suppose a manufacturer advertises:

“Up to 10 km.”

That statement may have been measured in conditions such as:

• Open land
• Clear line of sight
• Minimal electromagnetic interference
• No concrete walls
• No steel structures
• Few surrounding buildings
• Favourable antenna positioning

Those conditions are very different from:

• A warehouse
• Hotel
• Factory
• Shopping mall
• Hospital
• Office tower
• Construction project

Motorola’s own business-radio documentation warns that quoted maximum communication ranges are calculated under optimum, unobstructed line-of-sight conditions and that real range is often lower because of terrain, construction and local environmental conditions.

For a business buyer, therefore, “up to 10 km” should never be interpreted as “guaranteed 10 km everywhere.”

---

Walkie-Talkie Range Is Really a Coverage Question

Professional users should change the question.

Instead of asking:

“How many kilometres does this radio cover?”

ask:

“Will this radio system provide reliable communication everywhere my employees need it?”

That is a much more useful question.

A hotel may only be 150 metres from one end to another but contain:

• Eight floors
• Thick walls
• Lift shafts
• Basements
• Service corridors
• Kitchens
• Parking areas

A construction site may cover two kilometres but have relatively clear outdoor communication.

The physically smaller site may actually be more difficult to cover.

That is why distance alone cannot determine the correct radio.

---

The 10 Biggest Factors That Affect Walkie-Talkie Range

1. Line of Sight

Radio signals generally perform best when there are fewer obstacles between transmitting and receiving antennas.

Imagine two employees standing on opposite sides of a large open field.

Between them there may be:

• No walls
• No steel
• No machinery
• No tall buildings

That gives the radio signal a relatively clean path.

Now place those same employees at opposite ends of a large industrial building.

Between them there may be:

• Concrete walls
• Steel racking
• Machines
• Electrical equipment
• Elevators

The physical distance might be shorter, but the radio path is far more difficult.

This is why open outdoor range is often substantially better than indoor range.

---

2. Building Materials

Not all walls affect radio signals equally.

Different materials can absorb, reflect or weaken radio energy.

Common challenges include:

Reinforced Concrete

Concrete containing steel reinforcement can significantly reduce signals between floors and sections of a building.

Steel

Warehouses and factories can contain enormous quantities of steel in:

• Racking
• Machinery
• Structural beams
• Equipment
• Storage

Radio signals may reflect and scatter around these structures.

Basement Walls

Underground concrete structures can create particularly difficult coverage conditions.

Glass

Ordinary glass may create fewer problems than dense structural materials, although modern coated or metallised glazing can still affect wireless signals.

The building’s construction is therefore often more important than its physical dimensions.

---

3. Frequency: VHF vs UHF

The frequency band of a radio influences how signals behave.

Professional two-way radios commonly operate in either:

• VHF
• UHF

VHF

VHF generally performs strongly across open outdoor terrain with relatively few obstructions.

Typical applications may include:

• Agriculture
• Utilities
• Rural operations
• Open construction
• Outdoor field teams

UHF

UHF is commonly preferred where communication must take place through:

• Buildings
• Warehouses
• Hotels
• Factories
• Urban environments
• Multi-floor facilities

Motorola Solutions similarly describes VHF as generally stronger for wide open outdoor communication and UHF as better suited to indoor and obstacle-heavy environments.

This does not mean UHF always has “more range.”

It means the correct band depends on where the signal must travel.

Electrosonic’s existing guide on VHF vs UHF walkie-talkies discusses this distinction in greater detail.

---

4. Transmit Power

Radio output power is normally measured in watts.

In general, additional transmit power can improve communication capability under appropriate conditions.

But there is an important misconception:

Twice the wattage does not mean twice the range.

Radio propagation does not work that way.

More power may improve signal strength at the receiving radio, but it cannot magically remove:

• Concrete
• Hills
• Underground structures
• Steel walls
• Poor antenna placement

A higher-powered handheld can therefore still struggle in the same dead zone if the fundamental problem is structural obstruction.

Power matters.

It is simply one part of the link.

---

5. Antenna Quality

The antenna is one of the most important—and frequently overlooked—parts of a radio.

A radio may contain excellent electronics but still perform poorly if its antenna is:

• Damaged
• Incorrect
• Poorly matched to the operating frequency
• Loose
• Replaced with an unsuitable aftermarket antenna

Antenna length and design are related to the frequency range for which the radio is designed.

This means you should not assume that a larger antenna automatically gives greater range.

Use an antenna designed specifically for:

• The radio model
• The correct connector
• The correct frequency band

Electrosonic’s walkie-talkie antenna guide covers frequency matching and diagnosing antenna-related range problems in more detail.

---

6. Antenna Height

Radio antennas generally perform better when positioned away from ground-level obstructions.

This is one reason repeaters are frequently installed:

• On rooftops
• On towers
• At high structural points
• On elevated equipment rooms

A worker standing outside in an open elevated position can sometimes communicate much farther than someone located underground, even using a similar radio.

This is also why moving only a few metres can occasionally transform communication quality.

If a user experiencing poor reception:

• Walks outside
• Moves near a window
• Climbs to a higher floor
• Leaves a basement

and communication immediately improves, the problem is likely related to the propagation environment rather than a defective handset.

---

7. Terrain

Outdoor terrain strongly influences coverage.

Flat Open Land

Usually favourable.

Hills

A hill located between two users can block or weaken communication.

Valleys

Users at low elevation may struggle to reach other locations depending on terrain.

Forests

Dense vegetation can reduce signal performance.

Urban Areas

Tall buildings create reflection, shadowing and complex signal paths.

This is why a long-range radio test conducted on flat open land cannot predict performance in a hilly industrial property.

---

8. Radio Interference

Two-way radios operate in an electromagnetic environment that may contain many other signals.

Possible sources of interference include:

• Other radio users
• Electrical machinery
• Industrial electronics
• Power equipment
• Nearby transmitters
• Poorly shielded equipment

Interference can reduce usable range even if the basic radio signal appears strong enough.

Businesses operating large radio fleets should therefore consider frequency planning rather than simply adding more radios to the same channels.

---

9. Analog vs Digital

Analog and digital radios behave differently near the edge of coverage.

Analog

As an analog signal weakens, the user may gradually hear:

• Static
• Noise
• Distortion
• Broken speech

Communication becomes increasingly difficult as distance or obstruction increases.

Digital

Digital systems can often maintain clearer audio for a larger portion of the usable coverage area.

Then, when signal quality falls below the level necessary for decoding, communication may drop rapidly.

This is sometimes called the digital cliff.

Therefore, digital radio does not create unlimited range.

It can, however, provide more usable voice clarity across parts of the coverage footprint.

---

10. Repeaters and Radio Infrastructure

This is where the concept of “radio range” changes dramatically.

A handheld radio operating directly to another handheld is limited by the direct communication path between those two devices.

A repeater changes that path.

Instead of:

Radio A → Radio B

communication becomes:

Radio A → Repeater → Radio B

The repeater is generally positioned in a location where it can communicate effectively with users across a larger area.

This can help provide coverage through:

• Multi-floor buildings
• Large warehouses
• Industrial campuses
• Multiple buildings
• Parking structures
• Outdoor yards

Electrosonic’s existing repeater guide explains how properly positioned repeaters can extend communication beyond what direct handheld-to-handheld operation can achieve.

---

What Range Should You Expect in Different Environments?

Exact distances cannot responsibly be guaranteed without a site test.

However, it is useful to understand the relative difficulty of different environments.

---

Open Outdoor Areas

Typical Signal Environment:

Excellent

Open areas usually provide the greatest direct radio coverage because there are fewer obstacles.

Examples include:

• Agricultural land
• Large open construction areas
• Outdoor events
• Utility corridors
• Open parking facilities
• Flat industrial yards

Two radios with clear line of sight may communicate over substantially greater distances than the same devices inside buildings.

Main Factors:

• Terrain
• Antenna height
• Frequency
• Transmit power
• Vegetation

This is where advertised maximum-range figures are most likely to resemble real-world performance.

---

Dense Urban Areas

Typical Signal Environment:

Moderate to difficult

Cities contain:

• Buildings
• Concrete
• Glass
• Metal
• Moving vehicles
• Other RF systems

Signals may reflect between buildings or become blocked entirely.

Two users located only one kilometre apart may experience poor communication if several structures are between them.

At the same time, users positioned with favourable line of sight from elevated locations may communicate much farther.

Urban radio range is therefore highly variable.

---

Inside Office Buildings

Typical Signal Environment:

Moderate

Modern offices may contain:

• Partition walls
• Elevators
• Glass
• Concrete cores
• Electrical equipment

A small office may be extremely easy to cover.

A large multi-storey headquarters may require more careful planning.

UHF radios are frequently chosen for this type of environment because they generally perform better around structures than VHF.

---

Hotels and Resorts

Typical Signal Environment:

Moderate to difficult

Hotels present unusual challenges.

Staff may need communication between:

• Reception
• Guest floors
• Kitchens
• Basement engineering
• Housekeeping rooms
• Parking
• Security
• Outdoor gardens

One hotel may operate reliably without additional infrastructure.

Another of similar physical size may have serious dead zones because of building construction.

For larger hotels, coverage should be tested before a fleet is purchased.

---

Warehouses

Typical Signal Environment:

Moderate to difficult

Warehouses can look open but create significant radio challenges.

The problem is often the contents.

A warehouse may contain:

• Steel racking
• Forklifts
• Dense inventory
• Refrigerated rooms
• Loading equipment
• Mezzanines
• Containers

Signals can change depending on how inventory is arranged.

A radio system tested when a warehouse is nearly empty may behave differently when every rack is fully loaded.

This is why real operating conditions matter.

---

Manufacturing Plants

Typical Signal Environment:

Difficult

Factories can be among the most challenging business environments for radio communication.

They may contain:

• Heavy machinery
• Steel
• Electrical equipment
• Production cells
• Enclosed rooms
• Multiple buildings
• Basements
• High noise

Electrosonic’s manufacturing-radio guide specifically identifies basements, heavy machinery, separate production halls and loading areas as common locations where coverage issues can occur.

For large plants, a repeater system may be far more effective than trying to solve every problem by purchasing a supposedly “longer-range” handheld.

---

Construction Sites

Typical Signal Environment:

Changes over time

Construction is unusual because the radio environment evolves as the building is created.

During early construction, communication may be excellent because the project is relatively open.

Months later, the site may contain:

• Concrete floors
• Basement levels
• Lift shafts
• Multiple towers
• Steel structures
• Temporary buildings

Coverage therefore needs to be reviewed during major phases of the project.

Electrosonic’s construction guide notes that repeater locations may even need to move as new structures are added and begin blocking previously clear signal paths.

---

Hospitals

Typical Signal Environment:

Moderate to difficult

Hospitals often contain:

• Multiple floors
• Thick walls
• Service corridors
• Basements
• Diagnostic equipment
• Separate wings
• Parking structures

The objective should not simply be reaching “X kilometres.”

The real objective is ensuring reliable communication between all relevant operational zones.

---

Residential Societies and Gated Communities

Typical Signal Environment:

Highly variable

A small gated property may be simple to cover.

A large residential society can contain:

• Multiple towers
• Basement parking
• Clubhouses
• Security gates
• Gardens
• Service roads

Communication between the ground floor of one tower and basement of another may be much more difficult than communication across an open road.

Large properties should therefore be tested location by location.

---

Why One Radio Works and Another Doesn’t

Businesses frequently assume that if two radios have similar advertised wattage, their range should be identical.

That is not necessarily true.

Real performance also depends on:

• Receiver sensitivity
• Antenna design
• Radio tuning
• Audio quality
• Digital processing
• Build quality
• Frequency programming
• System infrastructure

This is why buying purely according to maximum wattage or kilometre claims can lead to disappointing results.

A professional radio should be evaluated as a complete communication tool, not simply a transmitter.

---

Does a 5-Watt Walkie-Talkie Go Twice as Far as a 2-Watt Radio?

No.

This is one of the most common misunderstandings about radio range.

Increasing transmit power can help improve signal strength, but radio range does not increase proportionally with wattage.

A 5-watt radio does not automatically provide 2.5 times the range of a 2-watt radio.

If a concrete basement wall is preventing communication, the extra power may provide relatively little benefit.

If the problem is weak signal across open terrain, additional power may help.

That is why the cause of poor coverage must be identified before choosing a solution.

---

Can a Better Antenna Increase Walkie-Talkie Range?

Potentially—but only if it is the correct antenna for the radio and frequency.

A properly matched antenna can improve radio performance.

But replacing a perfectly functioning antenna does not automatically solve a site-wide coverage problem.

Suspect an antenna issue when:

• One radio performs worse than identical units
• The antenna is damaged
• The connector is loose
• Performance changes when another correct antenna is installed

Suspect a coverage problem when:

• Every radio fails in the same location
• Basements always lose signal
• Communication fails behind a specific structure
• Moving outside restores communication

In that situation, site planning or repeater infrastructure may be required.

---

Can You Increase Range by Going to a Higher Floor?

Often, yes.

Moving a radio higher can improve the signal path because there may be fewer surrounding obstructions.

This principle explains why:

• Radio towers are tall
• Base antennas are placed on rooftops
• Repeaters are installed at elevated positions

Even moving from a basement to ground level can produce a dramatic difference.

When troubleshooting radio coverage, changing position is one of the easiest diagnostic tests.

---

Why Basements Create Walkie-Talkie Dead Zones

Basements combine several difficult conditions:

• Underground position
• Reinforced concrete
• Steel structures
• Limited openings
• Multiple floors between users

This can dramatically weaken the signal.

Underground parking areas are therefore among the most common locations where organisations discover coverage problems.

Potential solutions include:

• Better repeater placement
• Dedicated antennas
• Additional infrastructure
• Proper site planning

Simply buying more handheld radios will not fix the physical signal path.

---

Why Elevators Are Difficult

Elevators are essentially metal enclosures travelling inside a heavily constructed shaft.

This can create extremely challenging RF conditions.

Businesses should never assume reliable communication inside lifts simply because the radio works in the corridor outside.

If elevator communication is operationally important, it should be specifically included in the site survey.

---

How Repeaters Extend Walkie-Talkie Range

Suppose two users are separated by several concrete walls and cannot communicate directly.

A repeater installed on the roof may have good communication with both users.

The communication route becomes:

User A → rooftop repeater → User B

The two handhelds no longer require a strong direct path to one another.

This makes repeaters especially useful for:

• Large factories
• Universities
• Hospitals
• Logistics parks
• Resorts
• Shopping centres
• Industrial campuses
• Multi-building properties

The repeater itself must be correctly:

• Positioned
• Programmed
• Licensed where required
• Matched to the frequency band
• Connected to an appropriate antenna

A repeater installed poorly may offer far less benefit than expected.

---

How Much Range Does a Repeater Add?

There is no universal number.

The answer depends on:

• Repeater power
• Antenna height
• Antenna gain
• Feed-line loss
• Terrain
• Building structure
• Frequency
• Handheld radio capability

The key advantage is not simply “more kilometres.”

It is that the repeater provides a better central communication path.

In many business properties, solving coverage is more about eliminating dead zones than extending the outer boundary of the system.

---

One Repeater vs Multiple Repeaters

A single repeater may be enough for:

• One large building
• A moderate industrial campus
• A warehouse complex

Very large properties may require multiple coverage points.

Possible examples include:

• Airports
• Universities
• Large hospital campuses
• Mining operations
• Huge industrial parks
• Multi-building logistics hubs

Systems can become significantly more complex at this level.

A proper radio survey becomes essential.

---

Can PoC Radios Solve Range Problems?

Sometimes.

Push-to-Talk over Cellular (PoC) radios use LTE or Wi-Fi rather than relying entirely on direct VHF/UHF communication.

For geographically distributed users, this can remove the normal local range limitation.

For example:

• Drivers across a city
• Mobile service engineers
• Multiple business locations
• Regional security teams

can potentially communicate through broadband networks.

However, PoC introduces a different dependency:

cellular or Wi-Fi network availability.

It is therefore not simply a “longer-range walkie-talkie.”

It is a different communication architecture.

For businesses choosing between these technologies, see Electrosonic’s guide to PoC radio vs traditional walkie-talkie.

---

Why Walkie-Talkie Range Tests Should Be Done on Site

For a business installation, a site test is often more useful than reading twenty product specifications.

A proper test should place users in the actual locations where they need communication.

Test areas should include:

• Reception
• Security gates
• Basement
• Rooftop
• Parking
• Stairwells
• Lift lobby
• Warehouses
• Loading bays
• Production areas
• Plant rooms
• Outdoor boundaries
• Separate buildings

The goal is not to answer:

“Does the radio work?”

The goal is to answer:

“Does the radio work reliably everywhere our employees need it?”

That distinction is crucial.

---

How to Perform a Simple Radio Coverage Test

Businesses can perform a basic pre-purchase test using the following process.

Step 1: Identify Critical Locations

List every important operational area.

Step 2: Identify the Hardest Pairs

Examples:

• Basement to top floor
• Security gate to warehouse
• Factory building A to building B
• Reception to underground parking
• Opposite ends of logistics yard

Step 3: Test Voice Quality

Do not simply listen for a signal.

Check whether speech is:

• Clear
• Understandable
• Consistent

Step 4: Test While Operations Are Running

A completely empty site may not reflect normal conditions.

Test with:

• Machinery operating
• Inventory present
• Vehicles moving
• Staff working

Step 5: Walk Through Transition Areas

Do not only test fixed points.

Security guards and maintenance teams move.

Test corridors, staircases and routes.

Step 6: Record Dead Zones

Mark locations where communication is:

• Weak
• Intermittent
• Completely unavailable

Step 7: Determine the Correct Fix

Possible solutions may include:

• Different band
• Correct antenna
• Better system programming
• Repeater
• Alternative repeater location
• Additional infrastructure

Five Common Walkie-Talkie Range Mistakes

Mistake 1: Believing the Maximum Range on the Box

Treat it as an ideal-condition specification—not a site guarantee.

Mistake 2: Buying the Highest-Watt Radio

Power is only one factor.

Mistake 3: Assuming More Expensive Means More Range

Premium radios may offer better audio, ruggedness and features without necessarily multiplying direct physical range.

Mistake 4: Ignoring the Building

A 200-metre industrial site can be harder to cover than several kilometres of open land.

Mistake 5: Buying 100 Radios Before Testing Two

Test the actual property first.

That simple step can prevent a very expensive mistake.

---

How to Improve Walkie-Talkie Range

If your existing radios are not providing reliable coverage, work through the problem systematically.

1. Check the Antennas

Look for:

• Damage
• Loose connections
• Wrong antenna models

2. Check Battery Condition

A degraded battery or equipment issue can affect performance.

3. Confirm Programming

Make sure radios use:

• Correct frequencies
• Correct channels
• Compatible settings

4. Identify the Dead Zones

Determine whether problems occur randomly or in the same locations.

5. Test Different Locations

Move:

• Higher
• Outside
• Near windows
• Away from machinery

If communication improves, obstruction is likely involved.

6. Review VHF vs UHF

The existing frequency band may not be optimal for the environment.

7. Add a Repeater Where Appropriate

Large sites frequently require infrastructure rather than simply different handhelds.

8. Conduct a Professional Site Survey

For mission-critical facilities, this is usually the safest approach.

Electrosonic’s guide on eliminating radio dead zones expands on these steps.

---

---

Gated Community

Typical requirement: Variable

Small properties may be simple; multi-tower developments may be challenging.

---

Airport or Major Infrastructure Site

Typical requirement: Very high

These environments generally require a professionally designed communication system rather than relying on direct handheld range specifications.

---

Walkie-Talkie Range vs Reliability

For business users, maximum range is not always the most important metric.

Imagine two systems.

System A

Works 3 km in ideal conditions but loses communication inside your basement.

System B

Has a smaller theoretical maximum range but works reliably:

• At the security gate
• Inside the warehouse
• In the basement
• Across production floors

Which is better?

For business operations, System B.

Reliability in the locations employees actually use is far more important than a large kilometre figure.

---

Long-Range Walkie-Talkies: What Should Businesses Actually Look For?

When businesses search for a long-range walkie-talkie, they should evaluate the entire solution.

Look at:

Frequency Band

VHF or UHF according to environment.

Output Power

Within the appropriate legal and technical configuration.

Receiver Performance

A radio must receive weak signals effectively as well as transmit.

Antenna

Correctly matched and professionally designed.

Audio

A weak but understandable transmission may still be operationally useful.

Battery Life

Long shifts require reliable endurance.

Repeater Compatibility

Important if the site later expands.

Digital Capability

May offer improved voice quality and system flexibility.

Ruggedness

Industrial sites need equipment capable of surviving the environment.

Supplier Support

Programming and system design can matter as much as hardware.

---

The Most Important Rule: Range Is a System Property

This is the main idea to remember from this guide.

Do not think of walkie-talkie range as a property of the handset alone.

Think of it as the result of:

Radio + antenna + frequency + site + user position + infrastructure.

Changing any one of those can change performance.

This explains why:

• A cheaper radio can sometimes work perfectly on one site.
• A premium radio can still experience dead zones on another.
• A repeater can produce a larger improvement than replacing every handheld.
• A site survey can save more money than chasing higher advertised kilometre numbers.

---

Frequently Asked Questions

How many kilometres does a walkie-talkie work?

There is no single fixed distance. Direct handheld range may vary from relatively short indoor distances to several kilometres in favourable open environments depending on radio specifications, terrain, buildings and antennas.

Can walkie-talkies reach 10 km?

Under favourable open conditions, some radio systems may communicate over long distances. A 10 km marketing claim should not be treated as a guarantee inside cities, buildings or industrial sites.

How far can walkie-talkies reach inside a building?

Indoor range varies greatly depending on the building. Concrete, steel, basement levels and floor count can significantly reduce communication. Motorola notes that some unlicensed radios inside buildings may operate at ranges around 100 metres in certain conditions, illustrating how different indoor results can be from open-air marketing claims.

What has better range: UHF or VHF?

VHF often performs better across open outdoor environments, while UHF is generally better suited to buildings and urban environments containing obstacles. The correct choice depends on the operating environment.

Does higher wattage mean longer range?

Higher power can improve signal strength, but range does not increase directly in proportion to wattage. Terrain, obstacles and antenna position can matter more.

Do digital walkie-talkies have longer range?

Digital radios can maintain clearer audio over much of their usable coverage area, but they are still affected by the same fundamental radio-propagation limitations.

Can an antenna increase walkie-talkie range?

A correctly matched, high-quality antenna can improve performance. An incorrect or damaged antenna can reduce performance significantly.

Does a repeater increase walkie-talkie range?

Yes. A repeater receives and retransmits radio signals from a strategically selected location, often improving coverage across large or obstructed properties.

Why does my radio work outside but not inside?

Building materials such as reinforced concrete, steel and underground structures can absorb, reflect or block radio signals.

Why does my walkie-talkie lose signal in the basement?

Basements are surrounded by dense structural materials and located below ground, making them particularly challenging for VHF/UHF radio signals.

What is the best walkie-talkie for long range?

There is no universal best model. The right solution depends on whether communication is required outdoors, indoors, across buildings, underground or over a wide geographic area.

Should I test walkie-talkies before buying?

For businesses purchasing a significant radio fleet, yes. Testing at the actual site is one of the best ways to identify dead zones and select the correct equipment.

---

Final Thoughts

So, how far can a walkie-talkie really reach?

The most accurate answer is:

As far as the radio system and operating environment allow it to communicate reliably.

A kilometre specification by itself tells you very little about whether a radio will work inside your factory, hotel, warehouse or campus.

Real range depends on:

• Frequency
• Power
• Antenna
• Terrain
• Building materials
• User location
• Interference
• Radio technology
• Repeater infrastructure

For small sites, direct handheld-to-handheld communication may provide everything employees need.

For larger buildings and campuses, repeaters may be required.

For distributed teams working across cities or routes, broadband PoC communication may sometimes be a more appropriate solution.

The best approach is therefore not to buy the radio advertising the biggest number.

It is to define your actual coverage requirement, test the difficult locations and build the communication system around your real working environment.

Electrosonic Technologies helps businesses select professional radio systems for warehouses, factories, security operations, construction projects, hotels, educational campuses, healthcare facilities and other commercial environments.

For a serious business deployment, the goal should always be reliable communication where your team works—not simply the highest range printed on a specification sheet.
