Your task  is to extend the computing network coverage for the staff and visitors at the Fashion  Hub located at the Canberra CBD.    The staff has long been asking for mobile communications and wireless connections  so that they can move around with their laptops and connect to the business through  mobile phones. The problem was security. As the fashion designers share their new  design ideas, it was a risk to consider using wireless communication mainly due to  potential attackers who may attempt to steal the new fashion design ideas. In addition,  there will be many shelves with clothes on – and a few partitions (in place of walls) that  can block out some wireless signals.    The existing shop is approximately 50 meters by 20 meters, and the newly extended  part will be 50 meters by 10 meters (right adjacent to the existing hub space). [Assignment 1 Part A]    Report the advantages and challenges of wireless communication technologies in  consideration of convenience, mobility, multipath signal interferences, signal dispersion,  and security issues. You may consider the above case example to consider ‘security  concerns by leaking a new fashion design’. How can such a security breach occur in a  wireless environment (is there a known example?). If you are making references to any  external resources (including websites), please provide a reference list.      [Assignment 1 Part B]  Your task is to select at least two of the following wireless technologies in relevance  to the case scenario above:   ZigBee   WiMax   Bluetooth   RFID   WLAN   IoT   5G    Then you will report on:  1. Introduction to the selected technologies  2. Use case example(s) of the selected technologies  3. Technical backgrounds on the selected technologies  4. Potential benefits of the selected wireless technologies to the business  5. Security concerns or resolutions of the selected wireless technologies  6. Final recommendations to the business clients (less than 100 words)  Prepared by: A/Prof Tony Jan Moderated by: Dr Sanjeeb Shrestha March 2021 Marking Guide:  Marks are allocated as indicated on each question, taking the following  aspects into account:  Criteria Description Marks  Assignment 1 Part A  Brief discussion of  wireless  technologies  Discuss the advantages and disadvantages  of  the wireless technologies in comparison  to wired technologies  7  Assignment Part B:  Section 1-  introduction  and case examples  Introduction to wireless technologies and  their pros and cons. Use of case examples  to  motivate the business director.  3  Assignment Part B:  Section 2 –  operational  mechanisms  Describe on how the selected wireless  technologies operate – in particular for  the aforementioned business  environment (and their potential  benefits)  5  Assignment  Part  B: Section 3 –  Security  vulnerabilities and  resolutions  Describe the known and unknown  security vulnerabilities and your  recommended resolutions. If available,  some evidence of  security testing.  3  Assignment Part  B: Report  structure  Inadequate structure, careless  presentation, poor writing , word limits  1  Assignment Part B:  Reference style  (IEEE)  Minimum 5 Proper different  referencing resources  1  Prepared by: A/Prof Tony Jan Moderated by: Dr Sanjeeb Shrestha March 2021 Marking Rubric for Exercise Answers    Grade    Mark  HD    80%  +  D    70%-  79%  CR    60%-  69%  P    50%-  59%  Fail

Wireless Communication
The wireless can be defined as the communication without having any usage of wires. To transfer the information which can be either data or the voice with the help of wireless communication we will require antenna. The antenna will be the device which has the efficiency of coupling RF energy from one medium to another medium. For this we will need receiver and transmitter so that we can have complete end to end wireless link. The wireless communication uses electromagnetic waves as the medium to carry the information between receiver and transmitted through any channel. 
Advantages of Wireless Communication
With the help of wireless communication, we can achieve following advantages. 
· The wireless frequency is able to penetrate through the world and the wireless networks become easy for installation anywhere on the basis of requirement and the choice will stop this help us to achieve the flexibility and it becomes the great benefit of having wireless network in which we do not have to install the wire cable.
· We can have easy installation for the wireless networks, and it is much easier to maintain as compared wired cable. It helps us through grow the network as per requirements and can have hundred to thousands of the customer in future. 
· The wireless network makes it easier to plan for the organization as compared with the wired network because in wireless software configuration for the power, frequency, or any other parameters. 
· With the help of wireless communication network, we can easily connect with the remote areas which are not inaccessible like behind the walls, hilly terrains, or buildings. 
· Wireless communication allows to achieve benefit of mobility, but it is not possible in wired communication.
· The end devices used for wireless communication are much cheaper. 
Disadvantages of Wireless Communication
Following are the disadvantages of Wireless Communication:
· It is easier for the attackers to hack wireless signals and it affects the privacy. We can use security algorithms like AES, WAP2, WEP and few others and few of the modulation techniques like DSSS or FHSS. 
· In the initial days the network was much slower with wireless environment but now we have advanced standard like IEEE 802.11 and 802.11ad which are available with LAN, and they provide same performance as provided by ethernet based LAN. 
· The wireless networks need some careful radio frequency planning during initial stage of installation. 
· The communication in wireless network is also subject to interference. There are different receiver and modulation techniques which can be used to make the system robust against interference. 
The most common types of wireless network threats are:
· Denial of service: In this attack it sends large amount of the traffic or viruses on the network so that it can hijack resources or introduce backdoors. 
· Configuration problems: In this the user may have incomplete configurations or the misconfigurations. 
· Rogue access points: In this attack the attacker can fool devices and connect them with the false access point. 
· Passive Capturing: Eavesdropping can be done in the range of access point for capturing sensitive information. 
· Freeloading:
