True or False: Increasing frequency can increase data throughput because carriers support more cycles per second.

True or False: Increasing frequency can increase data throughput because carriers support more cycles per second.

• A. TRUE
• B. FALSE
• C. Only in vacuum
• D. It reduces range

Answer: (A)

When thinking about data throughput, the amount of information you can send per second is driven by the channel’s bandwidth, not just the raw cycles per second of the carrier. Increasing frequency often opens up access to wider blocks of spectrum, and wider bandwidth lets you transmit more data either by sending more symbols per second or by using higher-order modulation that packs more bits into each symbol. So, with a higher carrier frequency and the resulting wider bandwidth, the potential data rate can increase, assuming the system can maintain a usable link quality. Of course, higher frequencies come with trade-offs: greater attenuation and shorter range can limit practicality, so real-world throughput depends on both bandwidth availability and how well the link performs. The statement isn’t claiming a universal rule without exception, but in terms of capability, increasing frequency can raise the potential data throughput when bandwidth increases. The other options don’t fit because the idea isn’t that throughput only happens in a vacuum, and while higher frequencies often reduce range, that doesn’t negate the possibility of higher throughput given sufficient bandwidth and good link conditions.
