I. Wireless Standards and Technologies
Q: Which IEEE 802.11 wireless standard offers the highest data rate among
802.11a, b, g, and n? A: 802.11n. It supports speeds up to 600 Mbps by
utilizing both 2.4 GHz and 5 GHz frequencies.
Q: Which IEEE standard working group defines Bluetooth technology? A: IEEE
802.15 (specifically 802.15.1).
Q: What type of waves are used for Bluetooth transmission? A: Low-power
radio waves.
Q: What is Cellular Digital Packet Data (CDPD)? A: It is a wireless service that
enables mobile internet access by supporting data packets over cellular
networks.
Q: Which waves possess higher frequencies than infrared transmission? A:
Visible light waves.
II. Multiplexing Techniques
Q: Which multiplexing technique is best for broadcasting local news via
analog signals on a television network? A: Frequency-division multiplexing
(FDM).
Q: What technique should a network administrator use to send analog data
via lasers through fiber-optic cables? A: Wavelength-division multiplexing
(WDM).
Q: Which multiplexing type is primarily used for digital signals between
connected devices? A: Time-division multiplexing (TDM).
Q: What is the difference between Synchronous and Asynchronous TDM? A:
* Synchronous TDM: Transmits signals from input sources via pre-assigned,
dedicated single time slots.
