Question-1
Advantages of wireless communication:
1. Mobility: Wireless communication provides a high amount of mobility due to radio waves
which can move in a free manner in the air. That's the main reason, this technology does not
seem perfect for tall buildings or high objects. It also doesn't tie receivers with a particular
location, it means that it works as hard-wires.
2. Convenience: A physical device will be connected to the jack walls to work with the wired
communications but it has this advantage that it is not connected with any type of wires or
cables, so it provides the high strength to all devices.
3. Flexibility: It can easily accommodate several number receivers for the system based on
traditional analog-like AM radio waves. The several types of equipment received and form a
wireless communication system which provides the facility of working with many systems.
Disadvantages of wireless communication:
1. Communication: The network of wireless communications is very slow. It means that it takes
so much time for sharing any data via the internet. Its performance is the same as the
traditional ethernet, like LANs.
2. Security: The signals or the data will be hacked out in many cases. It means that the concept
of security is very weak in wireless communication systems.
3. Interference: There are several techniques based on receiver or modulation makes the
wireless system robust to any type of interference. It is mainly subjected to interference.

Question-3
1st Reflection- Networking system with APAs
Acrylic Wi-Fi is a software that I used to design my hometown system of Wi-Fi. In this software
a built-in function of scanner Wi-Fi is used from which the nearby Wi-Fi devices can be scanned
easily. Using Acrylic Wi-Fi software access point names created for the devices used by users of
home Wi-Fi. It shows the detailed information of the scanned systems, at the same time the
number of channels, their speeds, Mac Address and the excess of other networks were shown. In
its network analyzer, this software provides appropriate security to all the connected devices.
All Wi-Fi devices are provided the real time signal strength. Acrylic Wi-Fi shows the strengths
of devices receiving signals and sending them with their access point names.
2nd Reflection-Signal strength variation with the changing distance
A wireless network should be able to achieve the desired signal strength for definite applications.
There should be a proper planning in a wireless connection to achieve the desired signal strength.
Signal strength depends on many things like background noise, number of clients and the various
applications running. Signal strength directly varies with the distance of the user device. As we
know that the most important part in making the signal strength good is frequency maintenance,
acrylic Wi-Fi selects 2.4GHz as the overlapping channel and 5GHz frequency band for the better
performance. As in this software operates the access points on non-adjacent channels. These
bands will not cross the windows and walls because of shorter bandwidth, area of coverage
would be smaller but with better performance, Selection of channel is really important in
obtaining higher access points.
3rd Reflection-Multiple objects enhancing the Signal Strength
Antennas are very important in transmitting data like video and voice streaming and enhancing
the signal strength. Likewise, there are some routers which help in transmitting signals.
Upgrading your router and antennas will help in boosting the signal. Wi-Fi extender or AKA
repeater can extend the signal. PLC devices or power line communication can be used to extend
the signal, it’s not a tool but it uses electrical wiring bringing Wi-Fi to the home town areas.
Range of the Wi-Fi signal can be extended by several feet by installing the Firmware into a
router of Wi-Fi.

While standing between the 15 to 30 meters, there would a need some metallic objects that will
enhance the Wi-Fi signal strength and efficiency, because a piece of paper can’t disturb any radio
signals. In this distance these metallic objects will be able to remove the signal-to-noise
increasing the SNR (signal to noise ratio) ratio.
