This set of Wireless & Mobile Communications Multiple Choice Questions & Answers (MCQs) focuses on “Paging System”.
1. Which of the following technology is mainly designed for indoor coverage?
a) Femtocell network
b) 3GPP
c) LTE
d) AMPS
View Answer
Explanation: Femtocell Network is a small-size Macro cell network designed for better indoor coverage. It began attracting attention from both industry and academy in late 2007.
2. Coverage of Femtocell Network is much larger than a regular Macro cell Network.
a) True
b) False
View Answer
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.
3. Which of the following is not a component of Femtocell network?
a) F-BS
b) Internet link
c) FGW
d) BSC
View Answer
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).
4. Which of the following is not true for Femtocell base stations?
a) Short range
b) Low power
c) High cost
d) Wireless handsets
View Answer
Explanation: Femtocell Base Stations (F-BSs) are short-range, low-cost, low-power indoor devices to provide service for wireless handsets. F-BS, which looks like WLAN Access Point (AP), is a small device with at least two wireless and internet interfaces.
5. Any existing wireless telecommunication standard cannot be used at F-BS wireless interface.
a) True
b) False
View Answer
Explanation: Wireless interface provides wireless radio access to Femtocell MSs. Any existing wireless telecommunication standard, such as UMTS/ CDMA200/ WIMAX/ LTE/ EV-DO, can be used at the F-BS wireless interfaces.
6. ________ acts as a gateway between the Internet and communication network.
a) F-BS
b) Internet link
c) FGW
d) BSC
View Answer
Explanation: Femtocell Gateway (FGW) is a service provider’s device that acts as a gateway between the Internet and the communication network. One side of FGW connects a large number of F-BSs via broadband Internet, and the other side of FGW is connected to the telephony core network.
7. Femtocell network has improved seamless coverage and enhanced capacity.
a) True
b) False
View Answer
Explanation: Femtocell Network is a so-called “double-win” strategy that brings benefits to both cellular users and cellular providers. It provides improved seamless coverage and enhanced capacity for cellular users.
8. In _________ all cellular users belong to open subscribers group (OSG) and can access F-BS unconditionally.
a) Closed access mode
b) Open access mode
c) Hybrid Access mode
d) Zero access mode
View Answer
Explanation: In open access mode, all cellular users belong to open subscribers group (OSG) and can access F-BS unconditionally. Several cellular service providers have plans to deploy F-BS for better service quality to cover public hole areas.
9. In _______ a closed subscribers group (CSG) is set by F-BS owner to allow only small portion of cellular users to be served in the Femtocell Network.
a) Closed access mode
b) Open access mode
c) Hybrid Access mode
d) Zero access mode
View Answer
Explanation: In closed access mode, a closed subscribers group (CSG) is set by F-BS owner to allow only small portion of cellular users to be served in the Femtocell Network. For example, people can install F-BS in their house and only household members can access F-BS to attain better service.
10. Femtocell Network has the capability to help Macro cell Network achieve seamless coverage.
a) True
b) False
View Answer
Explanation: Femtocell Network has the capability to help Macro cell Network achieve seamless coverage. It can attain higher network capacity by transmitting over an Internet link.
