Question 1

WiMAX provides&#10;A)simplex communication&#10;B)half duplex communication&#10;C)full duplex communication&#10;D)none of the mentioned

Accepted Answer

WiMAX provides full duplex communication, allowing simultaneous two-way communication between devices.

Question 2

WiMAX uses the&#10;A)orthogonal frequency division multiplexing&#10;B)time division multiplexing&#10;C)space division multiplexing&#10;D)all of the mentioned

Accepted Answer

WiMAX uses Orthogonal Frequency Division Multiplexing (OFDM) as its modulation technique to provide high data rate over a wide area.

Question 3

Which one of the following modulation scheme is supported by WiMAX?&#10;A)binary phase shift keying modulation&#10;B)quadrature phase shift keying modulation&#10;C)quadrature amplitude modulation&#10;D)all of the mentioned

Accepted Answer

WiMAX supports a variety of modulation schemes, including binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), and quadrature amplitude modulation (QAM), to efficiently use the spectrum and adapt to different channel conditions.

Question 4

WiMAX MAC layer provides an interface between&#10;A)higher transport layers and physical layer&#10;B)application layer and network layer&#10;C)data link layer and network layer&#10;D)none of the mentioned

Accepted Answer

WiMAX MAC layer acts as an interface between the higher transport layers and the physical layer, facilitating communication and data exchange.

Question 5

For encryption, WiMAX supports&#10;A)advanced encryption standard&#10;B)triple data encryption standard&#10;C)both (a) and (b)&#10;D)none of the mentioned

Accepted Answer

WiMAX supports both Advanced Encryption Standard (AES) and Triple Data Encryption Standard (3DES) for encryption, providing robust security options for wireless communication.

Question 6

WiMAX provides&#10;A)VoIP services&#10;B)IPTV services&#10;C)both (a) and (b)&#10;D)none of the mentioned

Accepted Answer

WiMAX provides both VoIP (Voice over Internet Protocol) and IPTV (Internet Protocol Television) services, leveraging its broadband wireless access to deliver these services.

Question 7

Devices that provide the connectivity to a WiMAX network are known as&#10;A)subscriber stations&#10;B)base stations&#10;C)gateway&#10;D)none of the mentioned

Accepted Answer

Subscriber stations are devices that connect to a WiMAX network, allowing users to access the network services.

Question 8

Which one of the following frequency is not used in WiMAX for communication?&#10;A)2.3 GHz&#10;B)2.4 GHz&#10;C)2.5 GHz&#10;D)3.5 GHz

Accepted Answer

WiMAX typically operates on frequency bands such as 2.3 GHz, 2.5 GHz, and 3.5 GHz. The 2.4 GHz band is commonly used for Wi-Fi, not WiMAX, which is why it is the correct choice.
