Description: Narrow bandwidth refers to a limited range of frequencies used for data transmission. In the context of technology, this term is commonly associated with communication systems that operate at lower frequencies, which restricts the amount of information that can be transmitted simultaneously. Unlike wide bandwidth, which allows for the transmission of large volumes of data at high speeds, narrow bandwidth is characterized by its reduced capacity, which can result in slower transmission speeds and lower signal quality. This type of bandwidth is particularly relevant in applications where simplicity and cost are critical factors, such as in voice communication systems or IoT devices that do not require large amounts of data. In design terms, systems that use narrow bandwidth are often easier to implement and can be more energy-efficient, making them ideal for specific applications where high-speed transmission is not the primary concern.
