Buying walkie-talkies for a business often begins with a deceptively simple question:

How many radios should we order?

A company with 80 employees does not necessarily need 80 walkie-talkies.

At the same time, buying only ten radios because ten employees normally use them can leave the organisation short when a unit is damaged, a battery is being charged, an additional supervisor joins a shift, or operations suddenly become busier.

The right number depends on how the organisation actually works.

A warehouse may assign radios by operational position rather than employee. A security company may issue one radio to every guard on duty. A hotel may give radios only to supervisors and selected operational staff. A manufacturing plant may need dedicated radios for maintenance, production, safety and security teams while keeping several spare units ready.

The objective is therefore not to calculate radios from total headcount.

It is to build a radio fleet that supports the maximum number of people who genuinely need simultaneous communication, while allowing for spares, charging, maintenance and future growth.

This guide explains a practical way to calculate walkie-talkie fleet size for businesses in India.

---

Why Buying One Walkie-Talkie Per Employee Is Usually the Wrong Approach

Imagine a company with 150 employees.

At first glance, purchasing 150 radios may appear logical.

But perhaps:

• 50 employees work at desks.
• 30 operate machines in fixed positions where supervisors handle radio communication.
• 20 work on different shifts.
• 15 are administrative employees.
• Only 35 people actually need instant operational communication at the same time.

Purchasing radios for every employee would create unnecessary cost and equipment-management work.

The opposite mistake is also common.

A business identifies 35 regular users and purchases exactly 35 radios.

Now there is no spare capacity when:

• A radio needs servicing.
• A battery fails.
• A charger develops a problem.
• An additional contractor joins the site.
• Shift handovers overlap.
• A special event requires additional communication.
• A radio is temporarily lost or damaged.

Good radio-fleet planning sits between these two extremes.

---

Start With Operational Positions, Not Employee Headcount

The most useful question is:

Which positions need access to instant communication during the busiest operating period?

A radio may belong to a position rather than a specific employee.

For example, a warehouse may require radios for:

• Warehouse manager
• Shift supervisor
• Receiving supervisor
• Dispatch supervisor
• Forklift coordinator
• Loading-bay coordinator
• Security gate
• Maintenance technician
• Inventory supervisor

Those positions may be filled by different employees on different shifts, but the number of radios required for the positions remains relatively stable.

This approach makes fleet planning much easier.

---

Step 1: Identify Every Role That Actually Needs a Radio

Begin by listing departments.

Depending on the organisation, these could include:

• Security
• Maintenance
• Engineering
• Production
• Warehouse operations
• Dispatch
• Logistics
• Housekeeping
• Parking
• Facilities
• Safety
• Administration
• Event operations
• Transport
• Management

Then identify which positions within each department genuinely need real-time group communication.

Example: Commercial Building

Position	Radios Needed During Peak Shift
Security guards	8
Security supervisor	1
Facility manager	1
Maintenance technicians	3
Housekeeping supervisors	2
Parking supervisor	1
Control room	1
Total active radios	17

The building employs considerably more than 17 people, but only 17 operational positions need simultaneous radio access.

That number becomes the starting point—not the final purchase quantity.

---

Step 2: Calculate Peak Concurrent Users

Businesses operating shifts should calculate the highest number of simultaneous users rather than adding together everyone who uses a radio during the entire day.

Consider a factory with:

• 18 radio users on morning shift
• 22 on evening shift
• 12 on night shift

The company does not necessarily need 52 radios.

If radios are handed over between shifts, its starting requirement might be based around the busiest shift of 22 users.

However, there is another issue to consider:

shift overlap.

If the morning team and evening team are both present for 30 minutes during handover, radios may temporarily be needed by both groups.

This is particularly relevant when the handover itself requires communication.

---

Account for Shift Changes

Suppose:

• Morning shift uses 18 radios.
• Evening shift uses 22.
• Six outgoing supervisors and key operators retain their radios during a 30-minute handover.

The requirement during the overlap could temporarily rise above 22.

Businesses with structured shift changes should therefore calculate the maximum number of devices required at any one moment, not just the largest individual shift.

---

Step 3: Decide Whether Radios Are Shared or Individually Assigned

There are two common fleet models.

Shared Radio Fleet

Radios remain at the workplace and are issued at the start of each shift.

For example:

Radio 01 — Main Gate
Radio 02 — Loading Bay
Radio 03 — Maintenance
Radio 04 — Security Supervisor

At the end of the shift, each radio is returned and prepared for the next team.

This works well for:

• Warehouses
• Factories
• Hotels
• Hospitals
• Commercial buildings
• Schools
• Industrial plants
• Security operations

Advantages

• Fewer radios may be required.
• Equipment remains at the site.
• Charging can be centralised.
• Radio availability is easier to monitor.
• Units can be assigned by position.

Challenges

• Equipment needs proper handover procedures.
• Shared radios should be cleaned where appropriate.
• Employees must return units reliably.
• Batteries must be ready for the next shift.

---

Individually Assigned Radios

Some organisations assign a radio to a particular employee.

This may be appropriate for:

• Managers
• Field engineers
• Mobile technicians
• Security supervisors
• Senior operations staff
• Employees travelling between sites

The advantage is accountability.

The employee becomes responsible for:

• Charging
• Physical condition
• Accessories
• Returning the device if leaving the organisation

However, individual allocation normally increases the total number of radios required.

---

Step 4: Add Spare Walkie-Talkies

A business should generally avoid purchasing exactly the same number of radios as its maximum active users.

Some reserve capacity is useful.

Why?

Because professional equipment still needs:

• Maintenance
• Battery replacement
• Inspection
• Repair
• Cleaning
• Reprogramming

Radios can also be:

• Accidentally dropped
• Temporarily misplaced
• Left uncharged
• Damaged by water or dust
• Needed by an unexpected additional user

A spare pool prevents one unavailable radio from becoming an operational problem.

---

What Percentage of Spare Walkie-Talkies Should a Business Keep?

There is no universal percentage that works for every organisation.

A reasonable spare requirement depends on how critical communication is.

For example:

Small Non-Critical Fleet

A business using 8 radios may keep 1–2 additional radios.

Medium Operational Fleet

A business using 30 radios may choose several spare units so failures or temporary requirements do not interrupt operations.

Large Mission-Critical Fleet

Security, manufacturing, logistics and industrial operations may require more structured redundancy.

The key principle is:

Do not design the fleet so that 100% of available radios must work perfectly every day just to meet normal staffing requirements.

Even a small reserve provides valuable flexibility.

---

A Simple Walkie-Talkie Fleet Formula

Businesses can use the following approach:

Required Fleet = Peak Active Users + Shift-Overlap Requirement + Operational Spares + Special-Purpose Radios

For example:

Peak simultaneous users = 32
Additional shift-overlap radios = 4
Spare units = 5
Emergency/control-room radios = 2

Total planned fleet = 43 radios

This is usually much more accurate than either:

43 employees = 43 radios

or:

We normally use around 30, so let’s buy 30.

---

Step 5: Include Radios That Stay at Fixed Locations

Not every radio is carried by a person.

Some businesses keep radios at designated positions.

Examples include:

• Security control room
• Reception desk
• Main gate
• Fire-control room
• Loading dock
• Maintenance workshop
• Dispatch office
• Emergency response room

These devices must be counted separately.

A security operation with 15 mobile guards and three fixed radio stations may therefore require at least 18 active units before spares are considered.

---

Step 6: Consider Supervisors Who Need Access to Multiple Teams

Managers and supervisors often require radios even when they are not directly involved in routine field work.

For example, a logistics centre may operate:

• Receiving channel
• Dispatch channel
• Security channel
• Maintenance channel

The operations manager may need a radio capable of communicating with several groups.

Similarly, a hotel duty manager may need to reach:

• Security
• Housekeeping
• Engineering
• Front office

Do not exclude supervisors simply because they spend part of their time in an office.

The more useful question is whether they need immediate operational communication.

---

Step 7: Plan for Temporary Staff, Contractors and Visitors

Normal staffing should not be the only consideration.

Many businesses periodically need additional radios for:

• Contractors
• Auditors
• Event teams
• Maintenance shutdowns
• Seasonal workers
• Temporary security staff
• Construction crews
• VIP visits
• Large deliveries
• Emergency exercises

A hotel that normally uses 20 radios may temporarily need several additional units during a major conference.

A manufacturing plant may require extra radios during annual maintenance shutdowns when contractors enter the site.

A warehouse may require more units during peak seasonal dispatch periods.

If these situations happen regularly, they should be included in fleet planning.

---

How Many Walkie-Talkies Does a Security Team Need?

Security operations often have one of the clearest radio-allocation models.

Suppose a site has:

• 6 gate and access-control guards
• 8 patrol guards
• 2 parking guards
• 2 security supervisors
• 1 control-room operator

Peak active requirement:

19 radios

If the company then adds a practical spare reserve, the final fleet will be somewhat larger.

Security teams often benefit from near-individual radio availability because guards can be physically separated across a property and may need immediate contact.

However, the precise requirement depends on deployment.

Two guards permanently working beside one another at a small entrance may not always require separate radios, whereas two patrol guards operating independently usually will.

---

How Many Walkie-Talkies Does a Warehouse Need?

Warehouse requirements should be calculated by workflow.

Possible radio users include:

• Warehouse manager
• Shift supervisors
• Receiving team leads
• Dispatch team leads
• Inventory personnel
• Forklift coordinators
• Loading-dock supervisors
• Security
• Maintenance
• Yard operations

Not every picker or packer necessarily needs a radio.

For example:

A warehouse employing 100 people might have only 25–35 roles requiring regular radio communication.

Large distribution centres with multiple loading areas, outdoor yards and several operational zones may require considerably more.

Electrosonic’s existing guidance on radio range also explains why warehouse construction and dense storage environments can affect real-world communication, so fleet size and coverage planning should be considered separately.

---

How Many Walkie-Talkies Does a Hotel Need?

Hotels often benefit from selective radio distribution.

Typical users include:

• Duty manager
• Security
• Engineering
• Housekeeping supervisors
• Front-office supervisor
• Banquet operations
• Parking/valet
• Maintenance

A hotel with 150 employees may therefore need far fewer than 150 radios.

The purpose is not to give every housekeeper, waiter and receptionist a handset.

Instead, radios should connect the operational positions responsible for coordinating teams.

For larger hotels and resorts, several departments may need separate channels or talk groups so routine communication does not create excessive traffic.

---

How Many Walkie-Talkies Does a Factory Need?

Manufacturing sites vary considerably.

Possible users include:

• Production supervisors
• Shift managers
• Maintenance teams
• Electrical technicians
• Safety personnel
• Security
• Utilities
• Warehouse teams
• Dispatch
• Quality supervisors

A small factory may need fewer than 20 radios.

A large plant may require dozens or even hundreds.

The calculation should begin with communication-critical positions within each operating area.

Factories should also consider whether additional equipment is required for hazardous or specialised environments. A high IP rating, for example, does not automatically make an ordinary radio suitable for hazardous-area use.

---

How Many Walkie-Talkies Does an Event Team Need?

Event communication often requires a different calculation because the fleet may exist only for the duration of an event.

Priority users commonly include:

• Event director
• Assistant planners
• Venue manager
• Stage manager
• Security supervisor
• Parking coordinator
• Production/AV lead
• Catering lead
• Hospitality coordinator
• Transport team
• Backstage operations

Not every event worker needs a radio.

Instead, radios should usually be allocated to team leads and people whose decisions affect other departments.

Electrosonic’s existing event-planning guidance similarly recommends assigning communication equipment around operational roles and channel structure rather than automatically issuing radios to everyone involved.

---

How Many Channels Does Your Radio Fleet Need?

Fleet size and channel capacity are related but different questions.

A business might own 50 radios while using only four operational channels.

For example:

Channel	Department
1	Security
2	Operations
3	Maintenance
4	Supervisors

Alternatively, a small team of eight people may all communicate on one channel.

The number of channels should reflect:

• Departments
• Amount of radio traffic
• Need for separate conversations
• Supervisor responsibilities
• Emergency procedures

Too few channels can create congestion.

Too many channels can create confusion.

The goal is a structure employees can easily remember and use.

Digital radio systems can provide more structured communication options for larger fleets, while simpler analog systems may remain sufficient for smaller operations. Electrosonic currently maintains both analog and digital radio categories in its product catalogue.

---

Do You Need More Radios or Better Coverage?

This distinction is important.

Suppose a factory has 30 radios and users regularly report:

“We can’t reach the maintenance team from the far building.”

Buying five additional handheld radios will not necessarily solve the problem.

The organisation may already have enough radios.

What it lacks is reliable coverage.

Problems may instead involve:

• Building construction
• Distance
• Terrain
• Underground areas
• Metal structures
• Antenna positioning
• Frequency selection
• Dead zones
• Need for repeater infrastructure

Electrosonic has separate guides covering real-world range, dead zones and repeater deployment because these are system-design issues rather than fleet-quantity issues.

Before increasing radio quantity to solve a communication problem, determine whether the real issue is capacity or coverage.

---

Don’t Forget Charging Capacity

A business purchasing 40 radios also needs a plan for keeping 40 radios operational.

This is where fleet planning often becomes incomplete.

Questions to ask include:

• How many radios need charging simultaneously?
• Are radios used across multiple shifts?
• Will employees use individual chargers?
• Would multi-unit chargers be more practical?
• Are spare batteries needed?
• Where will charging equipment be located?
• Who checks battery condition?

A radio fleet without sufficient charging infrastructure can create morning or shift-change problems even if the business owns enough handsets.

Multi-unit chargers can simplify larger installations by allowing several radios or batteries to be prepared in a central location.

Electrosonic’s business-accessories guide specifically notes that accessory quantities do not always need to match radio quantities one-for-one and recommends planning batteries, chargers and audio accessories according to operational roles.

---

Calculate Radios and Batteries Separately

One radio does not necessarily mean one battery is enough.

Consider a site operating continuously for 24 hours.

A radio may be used on:

• Morning shift
• Evening shift
• Night shift

Depending on the equipment, duty cycle and charging arrangements, additional batteries may be useful.

Businesses should therefore calculate:

Number of Radios

and

Number of Batteries

as separate procurement decisions.

The same applies to:

• Earpieces
• Speaker microphones
• Chargers
• Belt clips
• Carrying cases

For example, 50 radios do not automatically require 50 speaker microphones.

Maintenance staff may need them while control-room employees do not.

---

Build Radio Kits Around Job Roles

For larger fleets, a role-based approach can simplify purchasing.

Security Guard

• Radio
• Belt clip
• Earpiece where appropriate

Security Supervisor

• Radio
• Audio accessory
• Spare battery if required

Maintenance Technician

• Radio
• Speaker microphone
• Appropriate carrying solution

Warehouse Supervisor

• Radio
• Speaker microphone
• Suitable battery arrangement

Manager

• Radio
• Lightweight audio accessory if required

This is more efficient than purchasing every available accessory for every handset.

---

Standardise the Fleet Where Practical

Suppose a company gradually purchases:

• 10 radios from one platform
• 8 from another
• 12 from a third
• 15 from a fourth

The equipment room may eventually need several different:

• Batteries
• Chargers
• Programming arrangements
• Antennas
• Speaker microphones
• Earpieces
• Replacement parts

This can make fleet management unnecessarily complicated.

Standardisation can simplify:

• Staff training
• Charging
• Battery inventory
• Accessory purchasing
• Programming
• Maintenance
• Spare-unit management

This does not mean every user must have the same radio.

Different operating environments may genuinely require different equipment.

The objective is to avoid unnecessary variety.

Electrosonic’s accessory guidance similarly notes that standardising around a smaller number of suitable radio platforms can simplify inventory, charging, training and maintenance.

---

Plan for Fleet Growth

Businesses often purchase radios based entirely on today’s requirement.

But operational needs can change.

A warehouse may add another dispatch section.

A school may open another building.

A factory may expand production.

A security company may receive a larger contract.

A hotel may add a new wing.

A logistics company may open another yard.

It can therefore be sensible to choose a radio platform that allows the fleet to expand without forcing the organisation to redesign everything.

Questions worth considering include:

• Can additional compatible radios be added later?
• Are batteries and accessories readily manageable?
• Can channel programming accommodate expansion?
• Is repeater support available if the site grows?
• Will the same radio type remain practical as teams increase?

Future planning does not mean buying dozens of unused radios today.

It means avoiding a system that becomes difficult to expand tomorrow.

---

Traditional Radios vs PoC for Large or Multi-Site Fleets

A business with one property has a different communication problem from a business with 30 locations.

Traditional two-way radios are well suited to defined sites such as:

• Warehouses
• Factories
• Hotels
• Hospitals
• Construction sites
• Commercial buildings

But a company with employees distributed across a city may need wider-area communication.

Push-to-Talk over Cellular, or PoC, uses cellular data infrastructure to provide push-to-talk communication over much larger geographic areas.

A business may therefore decide:

Local Site Teams

Use traditional two-way radios.

Regional Managers and Mobile Staff

Use PoC devices.

Electrosonic currently lists conventional analog and digital radios alongside PoC/LTE equipment and repeaters, reflecting the fact that different communication architectures suit different operating environments.

A fleet-planning exercise should therefore determine not only how many devices are needed but also what type of communication each user actually requires.

---

Should You Buy License-Free or Licensed Radios?

Fleet quantity does not determine regulatory requirements.

A company buying five radios and a company buying 100 radios still need equipment appropriate for their intended operating conditions and current Indian regulations.

Businesses should not assume that any programmable radio can automatically be used on any available frequency.

Electrosonic already maintains a detailed guide comparing license-free and licensed walkie-talkie systems in India, which is the better place to evaluate this question before deployment.

For fleet planning, simply include regulatory suitability as part of procurement rather than treating it as an afterthought.

---

Should Your Business Keep Emergency-Only Radios?

Some operations may benefit from keeping designated radios available for:

• Emergency response teams
• Visitors who need temporary access
• Senior management during incidents
• Fire and safety teams
• Backup control-room operation

These should not necessarily be counted as normal operational spares if they have a specific emergency purpose.

Otherwise, employees may gradually begin using the emergency reserve for everyday work, leaving nothing available when it is genuinely needed.

Clear labelling and inventory control can prevent this.

---

Radio Fleet Management After Purchase

Correct fleet size is only useful if equipment remains available.

Larger organisations should maintain a basic register.

This can include:

Radio ID	Assigned Position	Battery ID	Status
R-01	Main Gate	B-01	Active
R-02	Security Patrol	B-02	Active
R-03	Maintenance	B-03	Service
R-04	Spare	B-04	Ready

A simple system makes it easier to identify:

• Missing radios
• Damaged units
• Battery problems
• Equipment awaiting repair
• Available spares

Numbering radios is particularly useful when several identical units are stored together.

---

Track Battery Condition as the Fleet Ages

A fleet may begin with 40 perfectly functional radios.

Two years later, all 40 radios may still work—but several batteries may no longer provide satisfactory shift duration.

This creates the illusion of a radio shortage.

Employees begin searching for chargers or swapping radios midway through shifts.

The real issue may be battery ageing rather than handset quantity.

Fleet reviews should therefore examine:

• Radio condition
• Battery condition
• Charger condition
• Audio accessories
• Antennas
• Belt clips
• Cables

Replacing a battery can be considerably more sensible than replacing an otherwise functional radio.

---

When Should a Business Increase Its Radio Fleet?

Expansion may be justified when:

• Additional operational positions are created.
• Existing radios are being shared between people who need them simultaneously.
• Employees regularly wait for a radio to become available.
• Shift overlap has increased.
• New contractors require communication.
• New buildings or departments have opened.
• Spare radios are constantly being used as normal operational units.
• The business has no reserve equipment remaining.

The last point is particularly important.

If all spare radios are permanently in daily use, they are no longer spares.

That usually indicates the planned fleet size needs to be reviewed.

---

When More Radios Will NOT Solve the Problem

Buying additional units is not the answer when the underlying problem is:

• Poor signal coverage
• Incorrect channel configuration
• Employees using the wrong channels
• Damaged antennas
• Poor battery management
• Insufficient charging capacity
• Excessive radio traffic
• Incorrect radio type
• Lack of employee training

Identify the problem before increasing quantity.

A business with 50 poorly managed radios can have more communication problems than one with 30 well-planned radios.

---

Common Radio Fleet Planning Mistakes

Mistake 1: Ordering According to Total Employee Count

Not every employee needs a radio.

Calculate communication-critical positions.

---

Mistake 2: Buying Exactly Enough for Normal Operations

If 25 users require radios and the business owns exactly 25, a single failure creates a shortage.

Include a reserve.

---

Mistake 3: Ignoring Shift Overlap

Two shifts may temporarily need equipment simultaneously.

Include the handover period in peak-user calculations.

---

Mistake 4: Forgetting Fixed Radios

Control rooms, security gates and reception points may require permanent devices.

Count them separately.

---

Mistake 5: Forgetting Contractors and Seasonal Peaks

Temporary operations can increase requirements significantly.

Plan for predictable peaks.

---

Mistake 6: Buying Accessories in the Same Quantity as Radios

Different users need different accessories.

Build role-specific kits.

---

Mistake 7: Ignoring Charging Infrastructure

Enough radios with insufficient charging capacity still creates an operational shortage.

---

Mistake 8: Maintaining Too Many Unrelated Radio Models

Unnecessary model variety increases complexity in batteries, chargers, accessories and maintenance.

---

Mistake 9: Buying More Radios to Fix Coverage

Quantity and coverage are different problems.

A repeater, system redesign or site assessment may sometimes be more appropriate than purchasing additional handhelds.

---

Mistake 10: Planning Only for Today

Choose a system that can expand as operations grow.

---

Example: Calculating a 50-Person Security Operation

Consider a security contractor with 50 employees assigned to one large property.

They work in three shifts.

Peak Shift

• 14 guards
• 2 supervisors
• 1 control-room operator

Active requirement = 17 radios

Shift Handover

Four outgoing employees remain active during the incoming team’s briefing.

Additional requirement = 4 radios

Fixed Emergency Unit

Emergency-control position = 1 radio

Spare Pool

Operational reserve = 3 radios

Total

17 + 4 + 1 + 3 = 25 radios

The company has 50 security employees but may need only around 25 radios at that particular site because employees work in shifts and equipment is shared.

The precise quantity will depend on the organisation’s actual handover and equipment policy, but the example demonstrates why total headcount alone is misleading.

---

Example: Calculating Radios for a Warehouse

Consider a distribution warehouse.

Peak Users

• Warehouse manager: 1
• Operations supervisors: 3
• Receiving leads: 3
• Dispatch leads: 4
• Inventory team: 3
• Forklift coordinators: 4
• Security: 4
• Maintenance: 2
• Yard operations: 2

Peak requirement = 26 radios

Fixed Positions

• Security control: 1
• Dispatch office: 1

Subtotal = 2 radios

Spare Pool

Suppose the business plans 4 operational spares.

Total Fleet

26 + 2 + 4 = 32 radios

Again, the warehouse may employ far more than 32 people.

Fleet size is based on communication roles.

---

Questions to Ask Before Ordering Walkie-Talkies

Before finalising the purchase, answer these questions:

1. How many people genuinely need radios at the same time?
2. What is the busiest shift?
3. Do shifts overlap?
4. Are radios shared or individually assigned?
5. Which fixed locations require permanent radios?
6. How many spare units are appropriate?
7. Do temporary staff regularly need radios?
8. Which departments need separate channels?
9. Are supervisors communicating across several teams?
10. Is communication confined to one site or spread across several locations?
11. Is current coverage already reliable?
12. How will radios be charged?
13. Are spare batteries necessary?
14. Which users need earpieces or speaker microphones?
15. Can the chosen fleet expand later?
16. Does the equipment meet the applicable operating and regulatory requirements?

Answering these questions before requesting quotations usually produces a much more useful recommendation.

---

Frequently Asked Questions

How many walkie-talkies do I need for my business?

Calculate the maximum number of people who need simultaneous radio communication, add fixed-location devices, account for shift overlap and then include an appropriate number of spare units.

Total employee count alone is usually not a good calculation method.

---

Should every employee have a walkie-talkie?

Usually not.

Radios should be assigned to employees or positions that genuinely need immediate operational communication.

Team members who work together in one area may sometimes communicate through a supervisor.

---

How many spare walkie-talkies should I keep?

There is no universal number.

The appropriate reserve depends on fleet size and how critical radio communication is to the operation.

The important principle is to avoid running normal operations with every available handset in use.

---

Can employees on different shifts share walkie-talkies?

Yes.

Shared radio fleets are common.

Businesses should ensure that radios are returned, charged and ready for the next shift.

Shift overlap must also be considered.

---

Do I need one charger for every walkie-talkie?

Not necessarily.

Charging requirements depend on the equipment and operating schedule.

Multi-unit chargers can be practical for larger fleets because several radios or batteries can be managed centrally.

---

Should I buy spare batteries or spare radios?

They solve different problems.

A spare battery helps when a radio’s battery is depleted.

A spare radio helps when the complete handset is damaged, unavailable or being serviced.

Larger professional fleets may benefit from both.

---

Can more walkie-talkies improve range?

No.

Adding more handheld units does not automatically extend communication range.

Coverage issues should be evaluated separately and may involve site conditions, radio configuration, antennas or repeater infrastructure.

---

How many channels does a business need?

The number depends on the departments and amount of radio traffic.

A small team may use one channel, while larger operations may separate security, maintenance, logistics and supervisors.

Avoid creating more channels than employees can practically manage.

---

Is it better to give radios to individuals or positions?

For many shift-based businesses, assigning radios to positions is more efficient.

For managers, field engineers and mobile employees, individual assignment can provide better accountability.

Some organisations use both methods.

---

Should we buy extra walkie-talkies for future expansion?

You do not necessarily need to purchase a large number of unused radios today.

However, choosing an expandable platform and maintaining a reasonable reserve can make future growth easier.

---

Build the Fleet Around Your Operation, Not Around a Number

There is no universal formula such as:

10 employees = 10 radios

or:

100 employees = 50 radios.

Two organisations with the same workforce can have completely different communication requirements.

The correct fleet size depends on:

• Operational positions
• Peak simultaneous users
• Shift structure
• Fixed radio locations
• Temporary staffing
• Spare requirements
• Charging arrangements
• Department structure
• Site coverage
• Future expansion

Start by mapping who actually needs to communicate.

Then calculate the busiest operating period.

Add fixed positions.

Account for shift overlap.

Create a practical spare pool.

Plan batteries, chargers and accessories separately.

Finally, confirm that the selected radio system is suitable for the site’s coverage and operating requirements.

Electrosonic Technologies can help businesses evaluate professional analog and digital two-way radios, license-free options, repeaters, PoC systems and accessories based on team size, site layout, operational roles and communication requirements. Its current product catalogue covers these major professional communication categories for businesses planning new or expanding radio fleets in India.
