• IEEE 802.16 is a series of Wireless Broadband standards authored by the IEEE.
• The IEEE Standards Board established a working group in 1999 to develop standards 
• for broadband for Wireless Metropolitan Area Networks.
• The Workgroup is a unit of the IEEE 802 local area network and
• metropolitan area network standards committee.

C. Reduce the number of collisions

Carrier sense multiple access with collision detection (CSMA/CD) is a Media Access Control method in which:

• (1) A carrier sensing scheme is used.
• (2) A transmitting data station that detects another signal while transmitting a frame, stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame.

C. 1500 Bytes

The minimum payload is 42 octets when 802.1Q tag is present and 46 octets when absent and the maximum payload is 1500 octets. Non-standard jumbo frames allow for larger maximum payload size.

E. All of the above

HiperLAN (High Performance Radio LAN) is a Wireless LAN standard.[1] It is a European alternative for the IEEE 802.11 standards (the IEEE is an international organization). It is defined by the European Telecommunications Standards Institute (ETSI). In ETSI the standards are defined by the BRAN project (Broadband Radio Access Networks). 

• HiperLAN/1
• HiperLAN/2

A. 5GHz

It operates in the 5 GHz band with a maximum net data rate of 54 Mbit/s, plus error correction code, which yields realistic net achievable throughput in the mid-20 Mbit/s

B. Infrastructure mode

A. 4 Bytes

A. True

A. True

B. Speed of 10 Mbps

The common names for the standards derive from aspects of the physical media. The leading number (10 in 10BASE-T) refers to the transmission speed in Mbit/s. BASE denotes that baseband transmission is used. The T designates twisted pair cable, where the pair of wires for each signal is twisted together to reduce radio frequency interference andcrosstalk between pairs. 

A. Wireless Personal Area Network

• IEEE 802.15 is a working group of the IEEE 802 standards committee which specifies Wireless Personal Area Network (WPAN) standards. It includes seven task groups.
• Task Group 1: WPAN / Bluetooth
• Task Group 2: Coexistence
• Task Group 3: High Rate WPAN
• Task Group 4: Low Rate WPAN
• Task Group 5: mesh networking
• Task Group 6: Body Area Networks
• Task Group 7: visible light communication

B. Carrier Sense Multiple Access / Collision avoidance

C. STP

A. 5GHz

D. All of the above

D. A & B

Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecoms vendor Ericsson in 1994,[1] it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.
