Short Answer
Walkie-talkies can cover quite a distance, and it is one of the most crucial aspects that I need to consider when I buy this device. In one way or another, Walkie-talkie pretty much works like Bluetooth or Wi-fi. Approximately with a maximum range of 25 to 30 miles, this is how far a Walkie-talkie could reach.
Still, not all users can appreciate it because, in reality, we don’t have the perfect conditions. Within the line of sight, Walkie-talkie works best with an exposed medium with no interference. There is a shorter range of signals if I live in a City since it works by line of sight; hence, some of the factors affecting the performance of a Walkie-talkie are the following: distance, location, and landscape.
Long Answer
Knowing your topography and environment is the most excellent way before purchasing a Walkie-talkie to see the radio model that would suit me. VHF and UHF are just some of the radio models that I can choose based on my actual site. Regulating the radio frequency is now being mandated in the USA under Federal Communication (FCC). Here are the four different classes: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz).
FRS vs. GMRS
Even if I am not too familiar between Family Radio Service (FRS) or General Mobile Radio Service (GMRS), I can decide by breaking down their differences to aid me in finding the best type of radio that will suit my needs.
Due to the increasing competition for radio frequencies, I usually use FRS for a consumer like me since no small part uses it. The FRS can make cordless telephone conversations, and I don’t need to be stressed about interfered frequencies because I can freely use the FRS channels. On the other hand, GMRS has tracks that are not available in FRS radios, and it has specific frequencies inside the FRS 462-467 MHz. Moreover, GMRS can deliver some clarity because of its modulating frequencies that mean less interference.
Hence, FRS is fine if you are not using it frequently, like in outdoor scenarios or close range, because it can cover a mile or two with your other party if there is an emergency. But if I want peace of mind over a broader area, then I will use GMRS, which provides greater flexibility with the most clarity.
VHF vs. UHF
Meanwhile, I need to get to know the differences between VHF (Very High Frequency) and UHF (Ultra High Frequency), so that I would be able to classify the right signal frequency for this device.
VHF has 30 MHz to 300 MHz radio waves and is used on marine communications, FM radio broadcast, and long-range data communication. If I have severe applications, I won’t recommend using the low-band VHF because of its radio noise. Moreover, if I am using professional applications, I would typically use the high-band VHF; because it generally is being used by the general public such as wireless microphone devices. To achieve the best results, I would operate two to three frequency units due to its limited power to 50mW.
Around 12 to 24 inches is the actual measurement of UHF. UHF has a broader range of audio signals due to its extensive frequency and has a more significant bandwidth occupation. Hence, I am allowed to use up to 250 mW. High and low band UHF sometimes overlaps; for example, the high is 470-806 MHz while the low is 450-536 MHz. Using above MHz has tropical disturbances but requires antennas accordingly. If there is high frequency, then using UHF transmission has a high advantage because of its short wavelengths.
Obstructions
Walls are just some of the obstructions in the Walkie-talkie as there is a reflection that recoils back, such as an invisible straight line amid the radios and antennas. More so, Walkie-talkie has two-way radios with a 50 km (~35 miles) range. For reliable and operative communication, then I need to use the best long-range Walkie-talkies. Since there is a straight line of sight communication, then the environment is ideal for communication. So, if there are obstructions such as mountains or buildings, for example, then it will decrease the range of competences.
Tips to Increase the Range
The range can somehow limit the utility of Walkie-talkies, even if it is a flexible form of communication. Variables such as terrain or weather could affect these two-way radio range. Below are the tips to improve the content of my Walkie-talkie:
- Advance the antenna- Limited range will be prohibited if I advance my antenna to get the best signal as my radio is in the right position. Also, I can use the device to go to an uphill area to increase the range.
- Usage of a repeater- Extending a range could be best achieved using a signal repeater as it re-transmits the signal from my radio. Installing it in a tall tower or building will make me gain its all-out benefit.
- Good Batteries- The radio signal is greatly affected if I have low batteries. So, I need to examine if I have fresh ones frequently.
Conclosure – How far can Walkie Talkies reach?
Therefore, the maximum communication range for the Walkie-talkie is the distance of the horizon. If I want a more extended communication range, I will need a higher antenna for a farther signal. I can either use UHF or VHF, which works fine if I don’t need a long-range to cover. I would consider buying a repeater if I want a more extended range than any other radio provider. Generally, I would withstand the obstacle of communication if I have a stronger signal allowing the communication line to travel beyond.
