Narrowband

Narrowband refers to a telecommunications term that describes a limited bandwidth transmission channel. It is characterized by a transmission frequency range that is relatively small, which limits the amount of data that can be transmitted at any one time. This mode of communication is often utilized in applications requiring lower data rates, such as traditional radio communications and some forms of digital signal processing.

Narrowband meaning with examples

• In wireless communication systems, narrowband technologies are often preferred for applications like remote sensing, where low data rates suffice to transmit essential information over long distances without significant interference.
• Many legacy radio systems operate on narrowband frequencies, which allows them to transmit signals more effectively in environments with high ambient noise, making them suitable for emergency communications.
• Satellite communication often employs narrowband signals to ensure reliable transmission over vast distances, compensating for the distance-induced signal degradation that can occur in wideband systems.
• In IoT (Internet of Things) applications, narrowband networks provide a cost-effective solution for connecting a large number of devices while consuming less power, resulting in prolonged battery life for connected devices.
• The development of narrowband LTE (Long-Term Evolution) has revolutionized mobile communications in rural areas, as it offers better coverage and capacity for low-bandwidth applications compared to traditional methodologies.
