A. Wireless maximum communication
B. Worldwide interoperability for microwave access
C. Options. it is based on ieee 802.16 standards.
D. Wireless internet maximum communication
Explanation: WiMAX or worldwide interoperability for microwave access is a set of wireless communication standards. It provides support for multiple physical layer (PHY) and Media Access Control (MAC) options. It is based on IEEE 802.16 standards.
A. Simplex communication
B. Half duplex communication
C. Full duplex communication
D. No communication
Explanation: WiMax was developed to provide wireless broadband access to buildings. It can also be used to connect WLAN hotspots to the Internet. It is based on IEEE 802.16 standards.
A. Orthogonal frequency division multiplexing
B. Time division multiplexing
C. Space division multiplexing
D. Channel division multiplexing
Explanation: WiMAX physical layer uses orthogonal frequency division multiplexing as it provides simplified reception in multipath and allows WiMAX to operate in NLOS conditions.
A. Binary phase shift keying modulation
B. Quadrature phase shift keying modulation
C. Quadrature amplitude modulation
D. All of the mentioned
Explanation: WiMAX supports a variety of modulation schemes such as binary phase shift keying modulation, quadrature phase shift keying modulation, and quadrature amplitude modulation and allows for the scheme to change on a burst-by-burst basis per link, depending on channel conditions.
A. Higher transport layers and physical layer
B. Application layer and network layer
C. Options for higher layers to provide wireless broadband access to buildings. ???? register today for free c++ certification - january 2026
D. Session layer and application layer
Explanation: WiMAX provides support for multiple physical layer (PHY) on the physical layer and Media Access Control (MAC) options for higher layers to provide wireless broadband access to buildings.
A. Advanced encryption standard
B. Triple data encryption standard
C. Advanced encryption standard and triple data encryption standard
D. Double data encryption standard
Explanation: Both advanced encryption standard and triple data encryption standard are block cipher techniques and are popularly used in WiMAX and other applications for secure encryption.
A. Voip services
B. Iptv services
C. Both voip and iptv services
D. No iptv services
Explanation: IPTV can be transmitted over WiMAX, and relies on packet-switching to offer reliable delivery. VoIP can be operated over a WiMax network with no special hardware or software.
A. Subscriber stations
B. Base stations
C. Gateway
D. Switch stations
Explanation: Subscriber stations in WiMAX are transceivers (transmitter and receivers). They are used to convert radio signals into digital signals that can be routed to and from communication devices. There is a variety of types of WiMAX subscriber stations like portable PCMCIA cards and fixed stations that provide service to multiple users.
A. Local area network
B. Metropolitan area network
C. Personal area network
D. Wide area network
Explanation: WiMAX provides Wi-Fi connectivity within the home or business for computers and smartphones. WiMAX network operators typically provide a WiMAX Subscriber Unit to do so. The subscriber unit is used to connect to the metropolitan WiMAX network.
A. 2.3 ghz
B. 2.4 ghz
C. 2.5 ghz
D. 3.5 ghz
Explanation: The 2.4GHz ISM frequency band is used for personal area network technologies such as Bluetooth and hence is not suitable for WiMAX which is mostly used for Metropolitan Area Networks.
