GSLC · Question #243
Which of the following wireless standards has a transmission speed of up to 720 Kbps?
The correct answer is C. Bluetooth. Bluetooth 1.x wireless technology specifies a maximum effective data throughput of approximately 720 Kbps, distinguishing it from the much faster Wi-Fi and infrared standards.

Why each option
Bluetooth 1.x wireless technology specifies a maximum effective data throughput of approximately 720 Kbps, distinguishing it from the much faster Wi-Fi and infrared standards.
IEEE 802.11a is a Wi-Fi standard that supports transmission speeds of up to 54 Mbps, far exceeding 720 Kbps.
Infrared (IrDA) supports speeds up to 16 Mbps depending on the standard variant used, which is significantly higher than 720 Kbps.
Bluetooth 1.x operates at a raw radio data rate of 1 Mbps with an effective maximum throughput of approximately 721 Kbps due to protocol overhead, making it the only choice that matches the specified speed limit of 720 Kbps.
Wi-Fi is a general term for IEEE 802.11 standards that operate at speeds ranging from 11 Mbps to several Gbps, not 720 Kbps.
