Wi-Fi devices

Users B, D, and E can access Wi-Fi services because they are within line of sight of the Wi-Fi signals. There may also be interference in the Wi-Fi signal going to User D's device.

Implementing Wi-Fi access points

The following subsection describes the strategies used to implement an infrastructure of access points to relay communications in a Wi-Fi network. As a result, Wi-Fi resources accessed by the user may fail to load or freeze.

The Wi-Fi electromagnetic spectrum

Wi-Fi standards, modulation techniques and spectrum configurations

23 The IEEE has released several upgrades to the 802.11 standard to provide better Wi-Fi quality services to users. Devices that support the 802.11g standard will work on Wi-Fi networks that support the 802.11b standard.

Devices used by students to access Wi-Fi

Students’ usage times, and time spent, on Wi-Fi

Locations at which students use Wi-Fi

The following section discusses quality of service and explains the factors higher education institutions should consider when planning for Wi-Fi quality of service. Since higher education institutions provide Wi-Fi services, they should be concerned about the quality of the services they provide (Pitt, Watson, & Kavan, 1995).

Outcome quality

Therefore, they can affect the quality of Wi-Fi service results as perceived by users. For example, the Wi-Fi protected access encryption (WPA2) allows users to access Wi-Fi services after passing authentication (Soyinka, 2010).

Physical environment quality

The results showed that the physical appearance of the service location influenced the perceived service quality. However, there has been no study to investigate whether these factors can influence the perception of service quality at Wi-Fi locations in South Africa.

Quality of interaction with service providers

In addition, the temperature in a service environment can affect the perception of the physical environment's quality. The Wall and Berry (2007) study looked at the combined effect of the physical environment and employee behavior on customers' perception of restaurant service quality.

Perceived service quality

An investigation of student Wi-Fi usage found that students reported varying degrees of satisfaction with the Wi-Fi services they received. For example, the construct of outcome quality is explained by assessing the availability, reliability, timeliness and stability of the Wi-Fi network.

Perceived Wi-Fi service quality

The second part of the model states that the quality of the user's system device and the configurations of the technical access points can influence the quality of the Wi-Fi result (see Figure 7). From an infrastructure perspective, the literature has shown that network providers can use different access point configurations to deliver Wi-Fi services, which can affect the quality of Wi-Fi services provided (Bing, 2002; Held, 2003; Reynolds, 2003). Additionally, the qualitative approach allowed the researcher to interview ICS administrators to better understand the campus Wi-Fi infrastructure provided by the university.

Strategies for recording the data

The research instruments used in the study

The researcher conducted two interviews to obtain information about Wi-Fi infrastructure and usage at the university (see Appendix 4). The first section (Section IV) was aimed at understanding the Wi-Fi infrastructure available in the campus in general. The second part (Section V) aimed to understand whether there are problems with the Wi-Fi infrastructure from the students' perspective.

Procedures for collecting quantitative data

Procedures for collecting qualitative data

The quantitative data was collected in two phases, from May 26, 2017 to August 31, 2017, at the University of KwaZulu-Natal Westville campus. The second phase of data collection took place when the semester started, from July 16, 2017 to August 22, 2017. After analyzing the quantitative data, the researcher arranged interviews with two ICS employees to collect the qualitative data.

The collection and verification of completed questionnaires

Data coding

Data entry

Data entry began after the first phase of data collection and continued until all the questionnaires were captured. To ensure the accuracy of data capture, the researcher checked each questionnaire entered and compared the entered data from each response. Open-ended questions (including a response category of “other: please specify” and narrative descriptions) were entered as text into the Microsoft Excel data file to enable statistical analysis in SPSS.

Validity

To ensure data quality was maintained, most of the response options on the questionnaire were named in a way that made them easy to select using labeled check boxes rather than asking students to write down their responses. The study used the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy to extract data reliably.

Reliability

Quantitative Data Analysis

This test was used to see if there was a variance between the different groups, with the variability within each of the groups using an F ratio. The Chi-square fit test was used on categorical variables to test if any of the response options were selected significantly more/less often than others. The binomial test was performed to test whether a significant proportion of students chose one of the two possible answers.

Use of free Wi-Fi on campus

Locations UKZN Westville students prefer to access Wi-Fi services on campus

Very few students staying in on-campus residence halls chose the cafeteria (0.7%) or remote locations (1.4%) as their most used Wi-Fi locations. The locations where students experience a poor WiFi signal on campus have been analyzed per student residence (see Figure 18). The locations where students experienced the best Wi-Fi signal quality were analyzed based on where the students lived (see Figure 21).

How interaction quality affects perceived service quality

140 students will experience good quality of results, which will in turn improve the quality of perceived Wi-Fi services. Additionally, measures to improve the design of Wi-Fi locations, such as providing enough power outlets and enough seating, will make students perceive Wi-Fi locations to be of good quality; which in turn will improve the perceived quality. However, social conditions, which included student behavior at the Wi-Fi locations, had no effect on perceived service quality.

Factors which affect Wi-Fi outcome quality on Westville campus

Recommendations on the provision of Wi-Fi services in on-campus locations

These should identify and reduce possible sources of interference and obstructions at Wi-Fi sites. Priority should be given to locations where students experience poor Wi-Fi signal quality and where studying and learning are more likely to occur. For example, the library is reported as the second most used Wi-Fi location, and it is mostly used by students who live off campus, so the experiences here affect many of the students.

Recommendations on the use of resources over Wi-Fi

It is recommended that high-density access points that can handle large amounts of congestion, or multiple access points, be placed (in particular) in the library. In addition, the university can make more study or learning places available to students to reduce congestion at the access points in the library.

Recommendations on the use of Wi-Fi devices in on-campus locations

It is important to note that most laptops can provide more computing power than smartphones; thus, one measure that could ensure the success of the policy would be the placement of electrical outlets at Wi-Fi locations throughout the university, particularly in the library. Students should also be advised to disconnect devices that are not being used over Wi-Fi. This will reduce access point congestion and may improve the quality of Wi-Fi service for users accessing the same access point.

Recommendations on access point configurations

149 supported by the Wi-Fi devices and the benefits students can gain by purchasing laptops and smartphones that support the same Wi-Fi standard used at the university. The university has a 'bring your own devices' policy to encourage the use of laptops on campus (Vithal, 2015). However, the research shows that most students on campus use smartphones more than laptops (see Figure 25).

Recommendations for solving the difficulties faced by students while using Wi-

150 ICS administrators can educate students about measures to resolve Wi-Fi difficulties, such as moving when receiving a weak signal or approaching an access point. This can be done through a link sent to their app receipt telling them about the different Wi-Fi standards and devices to buy. Finally, when students face difficulties or problems with Wi-Fi, demonstrations can be offered to students in the call center so that they are able to help each other in the future to solve the same problem.

Recommendations for using the model to predict the perceived Wi-Fi service

The educational process may be completed before students come to UKZN as first years and/or before they purchase the laptops, tablets or smartphones they will use for their studies. If there was a YouTube video on how to connect to Wi-Fi, lecturers could make that connection available in first semester Moodle courses (especially).

Recommendations for further research

This study acts as a baseline for Wi-Fi usage and quality perceptions at the UKZN Westville campus. Many organizations are migrating from the most common local area networks to using Wi-Fi services.
