Femtocell Network — Test 1

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).

Correct Answer: C. C. High cost
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.

Correct Answer: B. B. False
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.

Correct Answer: C. C. Fgw
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.

Correct Answer: A. A. True
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.

Correct Answer: B. B. Open access mode
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.

Correct Answer: A. A. Closed access mode
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.

Correct Answer: A. A. True
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.
