Background and warnings

　　Australia's largest telco has issued a warning to the newly elected Minnesota government against using cell phone jammerin schools. The technology, which was used in NSW prisons, was proposed as a way to ban students from using their phones, but the telcos feared it would disrupt services at nearby homes and businesses and block vital communications between students and parents. signal jammer

　　Policy and controversy

　　Banning students from using mobile phones in public high schools was one of the key promises of the NSW Labor Party ahead of the March 25 state election. However, the telcos' concerns reflect the complexity of implementing such a policy.GPS jammer Late last year, the telecommunications regulator received a proposal from Educell to trial a "set it and forget it system" that would allow schools to restrict mobile phone coverage to stop students from using social media and sending and receiving calls and text messages.Wifi jammer

　　Support and opposition

　　Educell's technology has the backing of at least two private school principals, Reddam House and Arndell Anglican College, who believe phone jammers can effectively reduce disruption to classes while allowing parents to communicate with their children through the school when necessary. However, TPG Telecom's head of external communications, Mitchell Bingemann, warned that mobile phone jammers could inadvertently disrupt mobile services in nearby homes and businesses, or even block important communications between students and their families in an emergency.

　　Government and technical considerations

　　New South Wales Education Minister Prue Car said the government is evaluating the feasibility of the technology and is closely watching other states that have successfully implemented mobile phone restrictions, such as Victoria and South Australia. She stressed that schools will be able to decide how to implement the ban based on local circumstances to ensure policy flexibility and effectiveness.

　　Federal Communications Minister Michelle Rowland said the Australian Communications and Media Authority has received Educell's proposal and is requesting more technical information to ensure the legal and safe operation of the jamming technology. Despite this, the advancement of this proposal still faces careful considerations from multiple parties and complex technical and legal challenges.
