What is the actual communication range of walkie-talkies?
As a wireless communication tool, walkie-talkies have their own advantages when compared to mobile phones, especially in one-to-one and one-to-many fixed specialized communication. In particular, the one-to-many feature is something that regular mobile phones cannot easily replicate. With the continuous improvement of basic walkie-talkie functions and the expansion of their main uses, walkie-talkies are also widely used in government departments such as the military, police, security, ambulance services, and public utilities.
Apart from their professional applications, walkie-talkies have gradually become a part of people's daily lives. They are used in daily tasks, security, property management, construction sites, hotels, and other civilian scenarios. Many customers who are new to walkie-talkies often ask, "How far can walkie-talkies communicate?" Regarding the communication range of walkie-talkies, it actually depends on two key factors: communication distance and transmit power. Today, let's discuss how to determine the actual communication range of walkie-talkies.
1. Communication Distance:
Typically, communication within a range of 2-3 kilometers can be considered short-distance communication. For individual users, consumer-grade walkie-talkies can be purchased for such distances. For business customers, you can purchase low-power walkie-talkies by applying for the necessary licenses. If you want to ensure effective communication in urban areas with distances ranging from 3-10 kilometers, it is advisable to consider purchasing professional-grade walkie-talkies. If you need to communicate even further, it's best to use base stations with handheld walkie-talkies or mobile units with mobile-to-mobile communication capabilities. Base stations allow for the use of higher-power mobile walkie-talkies.
If customers require even greater distances or better communication quality and don't have their own network infrastructure, they can consider using trunking walkie-talkies. Trunking walkie-talkies rely on wireless communication networks and can achieve longer communication ranges. However, these types of walkie-talkies require internet connectivity, and if they go offline, similar to mobile phones, they won't work even for face-to-face conversations.
2. Transmit Power:
In the realm of wireless communication devices, transmit power is a critical factor. Similar wireless devices with different transmit power can have significant price differences. Additionally, transmit power directly affects the stability of data transmission in wireless networks. Therefore, paying attention to the transmit power of the chosen device is an important aspect of selecting wireless equipment.
The current transmit power of wireless network devices is sometimes directly indicated in the device's specifications, while others may use communication range to indicate transmit power. Typically, wireless devices should have transmit power ranging from 25mW to 50mW, or a communication range of 50 meters to 200 meters under normal circumstances. If you cannot find transmit power values on the device's nameplate or in the user manual, avoid making a purchase without this information.
The actual communication range of walkie-talkies depends on two key factors: communication distance and transmit power.
1. Communication Distance:
- Communication within 2-3 kilometers is considered short-range and suitable for consumer-grade walkie-talkies for personal use.
- For distances between 3-10 kilometers in urban areas, professional-grade walkie-talkies are recommended.
- To cover greater distances, especially in the absence of network infrastructure, trunking walkie-talkies can be considered. These rely on wireless internet support but won't work without an internet connection.
2. Transmit Power:
- Transmit power is a crucial factor in wireless devices, affecting both performance and price.
- Typical transmit power ranges from 25mW to 50mW, or communication ranges from 50 meters to 200 meters.
- Ensure you check the transmit power values in the device's specifications or documentation before making a purchase.
