The New South Wales Corrective Services Department is about to end its five-year trial of mobile jammer technology at Lithgow Prison, which has achieved significant results in preventing prisoners from illegally using mobile phones. However, although the Lithgow trial is seen as a success story, the technology still faces difficulties in being rolled out across the state. signal jammer

Since the Lithgow trial began in September 2013, the Australian Communications and Media Authority (ACMA) has not received any reports of the technology interfering with mobile services in nearby areas. The relatively isolated location of Lithgow Prison makes it difficult for jammers to spread to surrounding areas. However, not all prisons enjoy such unique geographical environments. For example, Goulburn Prison, located between Sydney and Canberra, is located near residential areas, which makes the deployment of jammers more complicated.

The Australian Mobile Telecommunications Association (AMTA) and the Communications Alliance, which represent mobile telecommunications companies, have in principle supported the transition of the Lithgow trial into a regular technology deployment. But they also made it clear that this support does not mean a widespread expansion to other facilities. In a joint submission to the ACMA, they pointed out that the environment of each prison is unique and the isolated environment of Lithgow is unlikely to be replicated elsewhere. Therefore, the deployment of jammers for each facility needs to be considered on a case-by-case basis.

Telecommunications Commission’s (NTC) ban on the online sale of SMS transmitters and warned the public against the use of devices, including illegal signal boosters and jammers. Although these devices are designed to help during times of extreme disasters, they can cause widespread network interference and affect the normal use of public communications.

Hazards of the devices

In an advisory, Globe Telecom said the use of illegal devices can cause a variety of network problems, including slow or failed network connections, dropped calls, poor voice quality, and even complete loss of mobile phone signal. Signal boosters appear to be beneficial by “occupying” the bandwidth of a base station to enhance network coverage and signal in a specific area, but in fact they interfere with radio waves and affect the mobile signal of other users near the booster.

Types of illegal devices and their impact

Illegal signal boosters often come in the form of indoor or outdoor antennas or wireless adapters. These devices “occupy” the bandwidth of a base station by boosting the signal in a specific area, thereby interfering with the normal service provided by the base station to other users. This interference not only affects the quality of users’ calls, but also causes interruptions in network connections and signal loss.
