A) four levels of security
B) coexistence with 802.15 WMANs
C) QoS
D) use of the 900 MHz spectrum

Question

Quizplus · Accepted Answer

Ultra-wideband (UWB) technology is known for its high level of security, offering multiple layers of security features, and it supports Quality of Service (QoS), which is crucial for ensuring that data transmission meets specific performance standards. UWB does not specifically use the 900 MHz spectrum; instead, it operates over a wide range of frequencies, typically from 3.1 to 10.6 GHz. Additionally, its coexistence is more relevant with other wireless technologies like Wi-Fi and Bluetooth rather than specifically with 802.15 WMANs (Wireless Metropolitan Area Networks), which is not a standard term (the correct term for Wireless Metropolitan Area Networks is 802.16, known as WiMAX).
