Detection of Active Mobile Phone in Exam Hall

Abstract

The use of mobile phone as a cheating tool in the examination hall among students have considerably increased a burden to invigilators to ensure integrity in examination hall. Many active mobile phone detection schemes had been proposed as the solution to this problem. However, the detection system function in a small detection range of 1.5 to 2 meters from the detection circuit and does not distinguish various frequency bands of radio frequency signals. In order to have diverse range of RF mobile phone signals detection for alerting the invigilators of their specified monitoring region, antenna is proposed to be used. This is done by antenna design simulation using Computer Simulation Technology (CST) software. Two types of antenna; single-dipole antenna and multi-band dipole antenna are simulated to know the characteristics of VSWR, gain and total efficiency. From the simulation results, multi-band dipole antenna shows acceptable VSWR value which are approximate to 2 V, gain is equal to 2.85 dB and total efficiency is equal to 2.484 dB for 2.4 GHz signal. The results imply positive event that multi-band antenna can be a preferable tool in elaborating accurate RF signal detection of active mobile phone in examination hall.

Glitches and hitches: sessional academic staff viewpoints on academic integrity and academic misconduct

“…Some students are tempted by the ease with which technology, such as mobile phones and smartwatches, can be employed to gather information to assist them answering exam questions. This form of cheating can be mitigated through the use of surveillance and detection technologies (Nazari et al, 2019) and the development of appropriate policies and protocols to govern the administration of assessments in an electronic environment (Landes & Freeman, 2019).…”
