Wondering about the difference between wideband and narrowband radio signals? Check out this blog post to learn the difference between each option.
Understanding various radio terms can be challenging but is important in determining which radio system is right for you. Two terms you might see when researching radios are narrowband and wideband. These terms refer to the bandwidth of the signals transmitted by these radios. Let’s look at narrowband vs. wideband radio signals and explore their differences.
Narrowband Signals
Narrowband radio signals are characterized by limited (narrow) bandwidth, typically less than 25 kHz. This narrower bandwidth results in lower data transmission rates than wideband signals, making it a great choice for areas with a high risk of interference. These smaller bandwidths prevent interference. Because the Federal Communications Commission (FCC) requires some channels to be narrowband, some radios can only operate in narrowband frequencies.
Applications of Narrowband Signals
Narrowband signals are commonly used in traditional two-way radio communications, walkie-talkies, and emergency service systems. These applications benefit from the efficient use of frequency bands and reduced interference.
Wideband Signals
Wideband radio signals encompass a broader range of frequencies, typically exceeding 25 kHz and extending into megahertz (MHz) ranges. Due to their larger bandwidth, wideband signals offer higher data transmission rates, enabling faster communication and data transfer. In areas with weaker signals, wideband frequencies can sometimes improve audio quality, allowing for more effective communication. However, these frequencies are more prone to interference.
Applications of Wideband Signals
Some radios, as well as radio repeaters, use wideband signals. If you plan to use a two-way radio repeater to extend the reach of your two-way radios, you must ensure your two-way radios also operate using wideband frequencies.
Now that we’ve explained narrowband vs. wideband radio signals and their applications, you can make a more informed decision about the right two-way radios for your needs. Check out Atlantic Radio Communications Corp. as you look for radios. We offer wideband and narrowband radios, including Icom CB radios, that make it easy for you to find the right communication tool for your organization.
