CHAPTER 3: PHYSICAL LAYER
Q1
Choice a Digital transmission of digital data
During the process of making call the mobile phone converts our sound into a pattern of numbers
(0s and 1s) then beam them via air. And this is done digitally since it involves the 1s and 0s. The
receiver will receive a signal which has been encoded from digital to analog (sound)
Q 2
Choice a LTE
Basically encoding is a process of sequential conversion of characters, symbols, data or alphabet
into a particular format to enable safe sending of data. And for this, the communication between
the tower and the rest of the world will because the data will still be transmitted to other places.
Q3
Choice a : Fiber optic cable
This is because for the sparsely populated and mountainous region it is very easy to have
the fibers for the transmission of data. Optic fiber can be go down to the bottom of the
mountain or top of the mountain with a lot of easy. And being that the area is not densely
populated it very easy to lay the optic fiber cables for the transmission of the signals.

Q 4
Choice b,
Repeaters boost the light transmission over a length of fiber optic cable. The repeaters are
powered, over a copper conductor, from the cable landing sites on each end (negative
voltage from one end, positive voltage from the other end).
A fiber optic cable could be a coordinate connect through which it interfaces one nation
to the rest of the globe for voice and information transmission. There are arrive as well as
submerged associations all over the world, connecting nations through an arrangement of fiber
optic cables (Carter, 2010). Larger part of the world’s broadcast communications and Web
activity streams through these arrange of cables. The submarine fiber optic cables are laid along
the seabed between land-based stations. These cables carry media transmission signals over the
sea; carrying phone, web, and private information activity. This can be illustrated using the
following diagram:
