What is walkie talkie range:-
A common confusion with hand-held radios is their range of communication. Radio manufacturers typically advertise maximum ranges under ideal conditions. While listed as having a maximum range, the actual range that can be used by radios depends heavily on the situation and is usually no where near that. While some consumers believe this is false advertising on the manufacturer’s part, others argue that these maximum ranges are truly the most objective metric. Whichever camp you belong to, it is our hope that this article will help you to understand the real range of what to expect while on trips.
How is the maximum range of a walkie-talkie determined?
During testing, manufacturer-specified optimum conditions are set up in order to determine the radio’s maximum range. To visualize this, consider the view from two hot air balloons on a clear day.
When these conditions are met, the signal should propagate only through the air, which is free from most environmental influences. The maximum range of a radio is determined by several factors, including:
- Output power
- Transmission frequency and antenna

Given the features and capabilities of a Walkie Talkie, two-way radio devices are one of the most efficient communication tools, and Walkie Talkie allow you to establish the most efficient connection throughout the organization. Using a walkie-talkie effectively requires you to understand the various frequencies that are used in the device.
License-free frequencies allow you to achieve up to 2.5 km of network connectivity.
How to convert a walkie talkie into a radio:-
A two-way radio’s power output plays a significant role in determining the distance it can communicate. This power output is measured in watts. It’s not uncommon to hear an FM radio station advertise it broadcasts at 50,000 or 100,000 watts.
In general, a handheld business-type two-way radio broadcasts at 1-5 watts, while a mobile vehicle radio might transmit anywhere from 5 to 100 watts. An enormous radio’s wattage will transmit farther than a smaller one. Why? Water in a pipe loses pressure.
Electricity in a wire loses current. An object in motion will eventually stop moving due to friction. There will always be signal loss along the path of radio waves due to the laws of physics.
However, if you apply more water pressure, more electrical current, or move a rolling object faster, you will obtain more distance from all of them. By increasing the wattage at the source, we overcome any resistance.
The higher the wattage, the faster your batteries will drain. For battery-powered handheld radios, less wattage might make sense.
Furthermore, the frequency of the two-way radio and the environment in which it is used will affect how far a radio will communicate.
Radios are classified into Ultra High Frequency (UHF) and Very High Frequency (VHF) bands. Neither band is necessarily more effective than the other. Each has its pluses and minuses. Choosing the correct radio for you will depend on your needs.
Wave Medium Carrier:-
Two-way radios transmit and receive a signal via radio waves. Each wave has a specific frequency, and a radio receiver can be tuned to just one of those frequencies to pick up that specific signal.
Radio waves consist of a series of cycles, one after another. The abbreviation “Hz” stands for cycles per second.
Hertz (No. of cycles) :-
Megahertz (MHz) is equal to 1,000,000 cycles per second; kilohertz (kHz) is equal to 1000 cycles per second. All radiofrequency units are derived from Hertz, a unit of frequency determined by the number of cycles per second.
Radios often use the term “wavelength” to describe their frequencies. Initially, radio waves were measured by the distance between the peaks of two consecutive cycles instead of by cycles per second. At lower frequencies, wavelengths are longer (cycle widths are larger).
Generally, a more extended wavelength corresponding to a lower frequency allows the transmission range of a radio signal to be more significant. This is important for two-way radios since it affects range under certain conditions.
It is also understood that waves with lower frequencies or longer wavelengths can penetrate the ocean water more deeply. This is why VLF (Very Low Frequency) radio waves (330 kHz) can communicate with submarines at shallow depths.
Why prefer VHF:-
You may have read above that VHF is always a better choice for a two-way radio because it has a lower frequency, and the signal can travel a greater distance than UHF. VHF penetrates more profound and has a more extended range does not necessarily make it the best choice for use inside buildings. Remember the discussion about wavelength above? Wavelength significantly affects transmission distance.
This can be illustrated by imagining that we communicate from one side of a metal building to the other. In between these two points is a metal wall with a three-foot opening. Metals usually do not transmit radio waves and usually block them. Let’s assume UHF wavelengths are about a foot and a half wide, and VHF radios are about five feet wide. These are the typical wavelengths of the radios.
VHF VS UHF:-
In the case of a UHF transmission, the energy wave passes through the door because it is wider than the wavelength. In the instance of a VHF transmission, the energy wave will be reflected since it is greater than the window opening.
Microwaves are an example of this. The glass front door has a metal grid with holes that are only a couple of inches long. Although the mesh keeps microwaves trapped inside the oven, it allows light waves to pass through, allowing you to see inside.
If you walk through the building with a five-foot pole, you’ll encounter the same barriers a VHF signal does. If you make it through the building with a pole that’s only two feet wide, there are much fewer doors that you can’t get through.
Barriers for signals:-
However, there is one caveat: wireless signals will not penetrate through drywall, masonry, other materials such as aluminum or aluminum alloy, human bodies, furniture, and wall panels, which will all reduce signal strength. The denser the material, the less the signal strength. Although VHF will penetrate these obstacles better than UHF, we will discuss why VHF might be better for indoor applications in the UHF section.
When we discussed the metal wall, we assumed it had an opening. VHF would win if you reversed this and put a metal object three feet in front of the transmitting radio. Despite being three-foot-wide, the object will block the UHF signal, but the VHF signal will get through it. Low frequencies, like VHF, are more easily broken up by smooth surfaces, as well as through brick and stone.
The UHF radio band ranges from 400 to 512 MHz. Until recently, it was not widely used for commercial radios. Now it is used for two-way radios, GPS, Bluetooth, cordless phones, and WiFi.
UHF may be less likely to have interference than VHF in more populated areas. UHF also has a lower range than VHF, but this may be beneficial in some cases. If your signal is affected by distant equipment, this may be a positive.
VHF is better at penetrating physical barriers such as walls, but that doesn’t mean it provides better coverage within a building. The shorter wavelength of UHF means that it can find its way through more spaces in your building. In the walk around with pole example, the UHF signal was blocked by fewer obstacles.
An excerpt from a brochure by a leading two-way radio manufacturer on a portable two-way radio’s predicted range indoors is provided here:
Note: Range and coverage estimates are only estimates and are not guaranteed. Indoor coverage at VHF is about 270,000 sqft and at UHF is about 300,000 sq ft. In addition to its longer wavelength, VHF has a hard time bouncing through walls, buildings, and rugged terrain.
In these environments, the VHF range will be reduced, but probably not a problem for short-range applications. Are you looking for something with a few hundred feet of range? You can also add an external antenna to an indoor VHF base station to mitigate some of the problems experienced.
An essential drawback of UHF is that the FCC requires a license to operate in these frequencies, even though many frequencies in the VHF business band require a license too. A license is not required in the VHF MURS bands (provided below).
The shorter wavelength produced by, the higher UHF frequency means the radio’s antenna can be made shorter than an equivalent VHF radio, making portable versions more convenient to use. However, most VHF radio manufacturers also find a way to make their antennas shorter.
Two-way radios, FM radios, and television broadcasts use VHF radio bands. The VHF broadcast band for commercial radios ranges from 130-174 MHz. Line-of-sight issues are common to both UHF and VHF radios, but VHF suffers a little more from them.
VHF frequencies are susceptible to problems with trees and rugged terrain. They may not work as effectively as UHF frequencies do. It is not uncommon for UHF and VHF waves to travel nearly twice as far if they could be broadcast over an area without obstructions, supporting VHF’s utility over a long range.
Why we prefer VHF:-
You are probably better off with a VHF radio if you are mainly working outdoors, especially if you are using a base station radio indoors and adding the external antenna. If the antenna is placed high enough, you will be able to transmit and receive far more.
Outdoor use of VHF radios is not recommended if you are in a heavily wooded area. Under these conditions, UHF radios may be able to transmit through trees more effectively.
Limited No of Frequencies:-
VHF radios also have a limited number of available frequencies.
Interference with other radios could be a problem. But the FCC provided a solution for this issue by opening up a two-way radio service called MURS, which stands for Multi-Use Radio Service. This is a short-range low-powered service meant to be used in the States and by some other countries that adhere to FCC rules.
Radio service on the VHF 150 MHz radio spectrum. Each channel has 38 privacy codes, so you can only hear conversations from radios that transmit your code. You do not need an FCC license to use MURS products.
How to Vary Frequency:-
If you want to increase the range, you can use MURS to add an external antenna.
If you need to add an antenna to your building or tower, you can do that with MURS. According to certain antenna manufacturers, an external antenna can boost a transmitter’s adequate radiated power by a factor of 4. Depending on the terrain and height of an antenna, MURS intercom systems can transmit several miles, and perhaps more, with an external antenna (up to 60 feet above ground level).
The battery life of VHF radios is usually better than for UHF models. This is a plus for handheld radios. The bottom line is that if you intend to use your two-way radio mostly inside buildings, then UHF is likely the best choice. However, VHF could still work well for many applications since it doesn’t have to transmit far.
The VHF signal will be an excellent choice if you are mainly using two-way radios to communicate outside unless you have lots of buildings in the way of the signal. Radio technology can be good for you if you don’t have a very long range to cover.
It is also possible to install repeaters that relay UHF signals, but this is usually very complicated to do as well. There may be a repeater service in your city that will provide this service for a monthly fee, but VHF or UHF radios will do just fine for most applications.
Comparison ( UHF Vs VHF):-
Generally, lower radio frequencies work better for more extended range applications. A typical VHF station emits about 100,000 watts and covers a range of about 60 miles. In comparison, a UHF station must transmit 3,000,000 watts to cover the same radius.
As such, there is no clear choice, VHF or UHF. Radio communications often involve a lot of “black magic” that makes it hard to tell which will work best for your situation. Detailed information on each technology is provided below so that you can make an informed decision.
