Answer 10.1: The very initial generation in AMPS system had used a frequency
allotment of various k frequencies along with a cell pattern that is basic in nature of around N=7,
suppose the N cells have been using the similar number of frequencies. K is considered as the
overall number of frequencies that is used in the system. Every cell has K/N frequency bands. In
AMPS, k- 395 and N=7 provides 57 frequency bands every cell in an average.
Answer 11.1: The LLC layer is usually on architecture in particular manner, along with
this it is similar to all the LANs that are defined in IEEE manner. The LLC protocol usually
handles the portion of end user of the frame, control information, logical address and data.
HDLC consists of only one field of address (Stallings, 2018). This is usually utilized for the
purpose of secondary station in a secondary as well as primary configuration. In a particular
LAN any station can be transmitted to any station which is not similar to the previous one. The
receiving station would require seeing its address for knowing the fact that the data is intended
for its own purpose (Li, Lei, 2016). It would also need to check the sending address, the address
that requires to be sent for the purpose of replying.
Answer 11.2: In case an asynchronous device such as teletype, is used for the purpose of
transmitting characteristics one at a time with numerous unpredictable delays between various
characters there are numerous problems that are faced. The issues are also faced in case the
device is connected to LAN. The issues include problems faced during logging in. in numerous
cases, the logging in is not actually successful even if they have the valid WLAN PEAP
password. Sometimes the user does not check the settings on the first page especially the settings
related to the third and sixth screen shots (Belt, Ahmadi and Doyle 2017). In some case the user
also does not change the default options of the device or machines. Sometimes settings usually
appear to be alright but the LAN does not seem to function effectively. In some cases when

teletype is connected to LAN for transmission, the power over Ethernet can be developed into a
particular key technology for the purpose of using Internet of Things. This happens because the
third PoC generation makes use of four wire pairs and supports outputs till 90 watts with the
current of around 1 ampere every wire pair in order to power numerous terminals.
These problems can be resolved by using various ways, these ways are as follows
 The testing of endpoint network- using this particular configuration, the tester
would act like a specific device on the network and it would have the capability to
detect and monitor problems which might not be visible during the use of
software troubleshooting tools (Ghassemlooy, Popoola and Rajbhandari 2017).
An important part of identifying the source of errors understands the network of
Ethernet.
 VoIP- the diagnostic options for the VoIP connections could also be helpful for
the purpose of troubleshooting. The tester usually connected between VoIP
telephones as well the network, measuring call quality of service (QoS) metrics
for confirming the reported call quality issues and then identifies the issues.
Answer 13.10: The compare and contrast of wired and wireless LANs are as follows
Wired network
 Wired network needs cables for carrying out a connection to every computer
network.
 The cost of a particular wired network is less than the ones charged in wireless
networks such as Ethernet, switches; cables are not at all expensive.
