Which statement about 900 MHz WLANs is supported by the material?

Which statement about 900 MHz WLANs is supported by the material?

• A. They are more expensive and provide slower data throughput.
• B. They offer higher throughput than 2.4/5 GHz.
• C. They require no regulatory compliance.
• D. They have the same cost as 2.4/5 GHz.

Answer: (A)

900 MHz WLANs trade data speed for range and penetration. The lower-frequency band offers longer reach, but the available spectrum and channel bandwidth are smaller, which limits maximum data throughput. Because devices for this band are less common and often specialized, they tend to cost more than the mainstream 2.4/5 GHz hardware. Regulatory compliance is still required for use in this band, so the idea of no regulation is incorrect, and the claim that costs are the same as 2.4/5 GHz isn’t supported by how these devices are produced and approved. So the statement that they are more expensive and provide slower data throughput aligns with how 900 MHz WLANs are described.
