WCDMA EXPERIMENTAL SYSTEM WORKSHOP
TEST
At least one statement in each question is correct.
1) What is the multiple access method in UMTS?
A) FSK (Frequency Shift Keying).
B) FDMA (Frequency Division Multiple Access).
C) CDMA (Code Division Multiple Access).
D) WAP (Wireless Application Protocol).
rd
2) Why do we need 3 generation of mobile telephony?
A) We need higher data rates.
B) The base stations today are too big.
C) We need to integrate datacom and telecom into one wireless product.
D) We need smaller mobile phones.
3) What is the purpose of having pilot symbols?
A) Eb/I0 measurement.
B) To keep track of the signal’s multipath delays.
C) To perform efficient power control.
D) Establish synchronisation between the mobile and the base station.
4) How can we remotely change the maximum output power of the base
station?
A) We can’t. A technician must go to the base station and manually twist
the power handle.
B) Open Netscape Web Browser and browse the base station’s
homepage, change the MaxOutPower parameter and click on the
"Apply" button.
C) Establish a telnet connection with the base station through the
connecting Ethernet and use the shell script to change the
MaxOutPower parameter.
D) Establish an FTP (File Transport Protocol) connection with the base
station and load up a reconfigured file, which specifies the changed
MaxOutPower parameter and restart the base station in order to
make the changes take effect.
