In terms of channel bandwidths, which of the following is a characteristic of narrowband systems? A) Requires less bandwidth compared to broadband B) Uses modulation and coding schemes up to 512 QAM C) Supports bandwidths up to 16 MHz D) Supports higher transmit power than broadband
Understand the Problem
The question is asking which option correctly describes a characteristic of narrowband systems in terms of channel bandwidths. This involves understanding the differences between narrowband and broadband systems, particularly in terms of bandwidth requirements and performance metrics.
Answer
Requires less bandwidth compared to broadband.
The final answer is Requires less bandwidth compared to broadband.
Answer for screen readers
The final answer is Requires less bandwidth compared to broadband.
More Information
Narrowband systems utilize a smaller portion of the frequency spectrum compared to broadband systems; hence, they require less bandwidth for transmission.
Tips
One common mistake is confusing narrowband and broadband due to their different applications. Remember that narrowband is suited for communication over larger distances at lower speeds and bandwidth compared to broadband, which supports higher data rates and wider bandwidth.
