INTRODUCTION

In this COVID 19 Pandemic situation, the only method to remain safe is Protection. Protection from the virus is possible by following proper hygienic rules and maintaining a social distance. Australian Business Institute of Technology and Systems aims to turn their entire campus wireless, so that the Institute can provide education by maintaining social distancing rules, which have become the necessity of hour in this Pandemic situation. Many wireless technologies are available, As a Wireless Network Engineer, working at Melbourne Institute of Networks in Australia, I would suggest two wireless technologies Wifi and Bluetooth that could be used by Australian Business Institute of Technology and Systems in their campus.

Rationale to select particular technologies

Wifi

Wifi Technology can be selected by Australian business Institute of Technology and systems due to the following main 7 reasons:[1]

• Use of Wifi at higher educational institutes will help the students to share and exchange information with each other in real time world.
• By using wifi, students will be able to learn even beyond the classroom walls.
• Through use of Wifi teachers will be able to prepare their lectures according to the learning styles of students.
• Use of Wifi will help the students to take the advantage of Online Database syatem, through which they would be possible to keep the track of their submissions.
• Wifi technology could be used at a cheaper rate compared to other wireless technologies.
• Use of Wifi will make the learning interactive and entertaining as students will be able to get exposed to new technologies.
• Use of Wifi will promote more and more engagement of students, as they will be curious to get attracted towards technology.

Bluetooth

Bluetooth Technology can be selected by the Australian Business Institute of Technology and systems due to the following reasons:[1]

• Use of Bluetooth Technology will provide more flexibility in education System.
• Students will be kept engaged, as they will be curious to use the technology.
• Exchanging of information becomes easier and smooth.
• Teachers will be able to connect their two devices simultaneously through Bluetooth device from any corner of the room thus focusing on interactive education.
• Use of Bluetooth Speaker in classroom will ensure the clear audible voice of teacher.
• The Bluetooth technology is even cheaper than wifi technology and hence it is cost effective.

Successful Business Case Examples that use the above technologies in Australia

The top 3 Australian companies which are successfully using the above technologies are:

1. DCSL Software Ltd: This is Australia’s top leading software development company which is using the above technologies successfully.
2. Software Relevant: Software Relevant is Australia’s top vendor company which is providing its service since 2013 and is successfully using these technologies.
3. Akras Software : Akras software is an ISO certified web development company in Australia with lakhs of Satisfied customer. This company is successfully using the above two wireless technologies since 2010.

Hence, Bluetooth and Wifi wireless technologies can be successfully used by the client.

TECHNOLOGIES AND COMPARATIVE ANALYSIS

Working Mechanism of Bluetooth:[2]

Bluetooth makes use of FHSS ( Frequency Hopping Spread Spectrum)[2]. The frequency range for operation of Bluetooth is 2.4 Ghz in the ISM band between 2.4Ghz- 2.48Ghz. It makes use of 79 channels. The random hopping of data channel takes place 16000 times/ sec between the 79 channels, dividing the time slots into 625 us long. Bluetooth makes use of data transfer techniques between the devices for sharing purposes. Bluetooth makes use of two types of data transfer techniques v.i.z SCO and ACL.

Two concepts i.e Bluetooth Protocol and Bluetooth Profile is used by Bluetooth for working. The range of operation for Bluetooth is approximately 1000 meters, which is short, hence it is used for short range communication purposes.

Working Mechanism of Wif :[2]

Wifi makes use of DHSS (Direct Hopping Spread Spectrum)[2].The frequency range of Wifi 2.4 Ghz or 5.2 Ghz. It makes use of 802.11 IEEE standard for communication purposes. Through DHSS technique , the division of 83mhz frequency takes place into 11 channels where each channel is of 22mhz wide.

In case of Wifi frequency hopping of channels do not take place. The range of wifi is more than Bluetooth. Like Bluetooth Wifi also makes use of two types of data transfer techniques v.i.z SCO(Synchronous Connection Oriented) and ACL( Asynchronous Connectionless)

Note: Both the Wifi and Bluetooth can be used at the same time, but since they use the same spectrum, interference is possible, which could degrade the data. So, Bluetooth can be used as an alternate for wifi when internet is not available.

Comparative Analysis[3]

	Bluetooth	Wifi
Frequency band	2.4 ghz	2.4ghz, 5mhz
Range of Communication	0- 100m	100m
Hopping Technique	FHSS	DHSS
Cell Structure	Piconet	BSS
Highest no of nodes	8	2007
Governing Authority	Bluetooth SIG	Wifi- alliance
Speed of Data rate	3mbits/sec	54mbits/sec

BUSINESS BENEFITS AND SECURITY CONCERNS

Business Benefits of using Wifi [4]

• Customers are happy and satisfied with the wifi access
• Employees associated with the business that makes use of wifi are satisfied and their performance is enhanced.
• Business which make use of Wifi are highly collaborative and productive which yields high profits.
• Business which makes use of wifi provides flexibility at work.
• Home based business are more benefitted by using wifi as starting of Enterprenership is possible by sitting at the comfort of your home.

Business Benefits of using Bluetooth[4]

• Bluetooth is wireless technology and hence business which makes use of Bluetooth does not have to deal with wiring mess.
• Bluetooth Technology is inexpensive and hence business making use of Bluetooth are able to make profits easily.
• Business making use of Bluetooth does not have to depend upon internet for sharing information.
• The best business benefits that the Bluetooth provides are mobility and low power consumption.

Security Concerns:

The main security concern of using Wifi and Bluetooth is unauthorised access of data due to which the CIA model i.e confidentiality, Integrity and Authenticity of an organisation gets hampered. If the passward is known to the intruder, then the confidential data can be hacked easily.

Security Concern for Bluetooth: The top Bluetooth attacks that prove a threat to security are:

• Eavesdropping: Devices which makes use of older version protocol are prone to a well known security attack called unpatched security holes.
• DOS Attack : DOS (Denial of Service) attack is a famous attack through which the device can gets crashed.
• Software Vulnerabilities: There is no software available, which is 100% perfect, so definitely the software used in Bluetooth will be prone to vulnerabilities.

Solutions: One of the best solution to deal with security issues related with Bluetooth is to switch off the Bluetooth when not in use.

Security Concern for Wifi: The only security cocern of using wifi is unauthorised access of data, through which the confidential data gets hacked.

Solutions: The best three ways to deal with security issues related with wifi are:

• Setting up Strong Password: A strong password consists of combination of numbers, letters and special characters, so password should be strong, which is difficult for the attacker to guess.
• Use of WAP: Wifi Access Points along with AES algorithm offer excellent protection against unauthorised access, as it blocks the unknown users.
• Static Allocation of IP address: The IP addresses of devices belonging to organisation should be allocated statically, due to which only the devices of organisation will be allowed to access the wifi and others will get blocked.

FINAL RECOMMENDATION TO BUSINESS

Final recommendation to business [5] means writing a recommendation letter to client regarding the use of product or service.
