Wireless Mobile Communications — Test 3

Correct Answer: D. D. Reduced bit rate
Explanation: Broadband Radio Access Network functionality ultimately aims to improve specifications which provide effective functionality at minimum cost. Their key requirement includes reduced cost, interoperability, managed Quality of Service and enhanced bit rates.

Correct Answer: B. B. Hiperlink
Explanation: HIPERLINK is exclusively utilized in infrastructure technologies considering its immense speed capability. Though HIPERLAN/ 2 and HIPERACCESS comprise greater speed functionality, they are utilized in multimedia applications and residential technologies respectively.

Correct Answer: B. B. False
Explanation: Frequency allocation is generally implemented for its application in space services, terrestrial and astronomy services. BRAN can never allocate frequency bands standardized by multiple regulatory bodies especially considering CEPT SE 19 standards, since it is exceptionally designed for harmonized standards only.

Correct Answer: C. C. 48 ghz
Explanation: HIPERACCESS standard involves certain lower and higher frequencies like 32 GHz, 28 GHz and 26 GHz (millimeter wave frequency zones). This standard excellently utilizes TDMA/TDM access methodology in entire frequency spectrum.

Correct Answer: A. A. True
Explanation: HIPERACCESS utilizes point to multipoint methodology efficiently, where the entire transmission methodology is implemented utilizing distinct varieties of one to multiple connections. This transmission method is broadly implemented in telephony and wireless internet schemes.

Correct Answer: D. D. 10 mb
Explanation: An equalizer is effectively utilized to compensate Inter Symbol Interference (ISI) within single carrier modem, whenever symbol rate succeeds standard numerical value of 10 MB. However, similar dilemma arises even though narrow beamed antennas are utilized in this process.

Correct Answer: A. A. Quadrature amplitude modulation (qam)
Explanation: QAM is best suited since it provides higher distance within adjacent points, promoting noise immunity and a single demodulator system detects amplitude and phase by minimizing system complexity.

Correct Answer: B. B. Spectrum sharing innovation test bed and spectrum management tools
Explanation: Spectrum Sharing Innovation Testbed and Spectrum Management Tools are the recommendations proposed in the Spectrum Policy Initiative created in 2003. Most of the recommendations pertained to the modification of the spectrum management infrastructure. The initiative states that technological advances can be exploited to overcome spectrum scarcity by spectrum sharing.

Correct Answer: B. B. False
Explanation: The “femto” means 10-15. Coverage of Femtocell Network is much smaller than a regular Macro cell Network that is why this name is given. Femtocell Network, installed by end users at home or in an office environment.

Correct Answer: D. D. Bsc
Explanation: Similar to UMTS Terrestrial Radio Access Network (UTRAN) architecture, the Femtocell Network consists of three components: Femtocell Base Stations (F-BS), Internet Link, and Femtocell Gateway (FGW).
