||
|
b. QPSK and M’ary QAM are both used as modulation techniques |
||
|

QUESTION Wireless Local Loop (WLL) does not include the use of optical frequencies.
True
False
Question 1
The correct option is, “True”.
PON uses splitters to channelize signals and each split has a 3dB
insertion loss.
Question 2
The correct option is, “False”.
WiMAX BWA is still popular despite the introduction of 4G LTE, as
WiMAX also provides support for non-mobile devices for
organizations and homes.
Question 3
The correct option is, d) “All the statements are
correct”.
WiMAX uses OFDM to carry data and increase spectral efficiency. It
uses QAM and QPSK for adaptive modulation.
Question 4
The correct option is, “True”.
WLL or Wireless Local Loop uses wireless links for
transmission.
