Key Differences
Narrowband communications transmit data over a narrow band of frequencies, typically supporting a single type of data stream, such as voice or low-rate data. This makes it efficient for specific applications but limits the bandwidth and data transfer rate. Broadband, on the other hand, utilizes a wider band of frequencies, allowing for the transmission of multiple data streams simultaneously. This results in higher data transfer rates and the capacity to support a variety of services like internet, television, and voice communications all at once.
While narrowband is characterized by its limited frequency range, resulting in lower data rates suitable for applications like voice calls and text messaging, broadband offers a much larger frequency range. This wider range supports higher data rates, making it ideal for data-intensive applications such as video streaming and high-speed internet access.
Narrowband's limited bandwidth makes it well-suited for applications requiring minimal data transfer, like IoT devices and certain industrial applications where efficiency and long-range communication are key. Broadband, however, is tailored for residential and commercial applications demanding high-speed data transmission, such as video conferencing, online gaming, and large file downloads.
The technological infrastructure required for narrowband is typically less complex and less expensive to deploy, making it a cost-effective solution for specific applications and in areas where broadband infrastructure is not feasible. Broadband, with its need for more sophisticated infrastructure like fiber optic cables, demands a higher investment but offers greater versatility and speed.

Narrowband
In radio communications, a narrowband channel is a channel in which the bandwidth of the message does not significantly exceed the channel's coherence bandwidth. In the study of wired channels, narrowband implies that the channel under consideration is sufficiently narrow that its frequency response can be considered flat.
Broadband
In telecommunications, broadband is wide bandwidth data transmission which transports multiple signals and traffic types. The medium can be coaxial cable, optical fiber, radio, twisted pair or satellite.
