Cape Town - The communications regulator of SA has slammed the alleged use of mobile signal jamming devices in Parliament during the State of the Nation address on Thursday night.
Minutes before President Jacob Zuma's speech descended into chaos, the opposition Democratic Alliance (DA) raised an objection to the use of jamming devices in the chamber.
Following debate with the Speaker on the details and reasoning for the alleged jamming, the signal was then reportedly restored.
But while signal jamming is sometimes used in prisons, its indiscriminate use is prohibited, according to the Independent Communications Authority of South Africa (Icasa).
"The position of the Authority (Icasa) on this matter is as follows: The use of jamming devices by any entity other than National Security Cluster Departments is not authorised and or permitted. The National Security Cluster departments may, where supported by relevant security legislation, deploy the use of jammers in relation to, amongst others, State security functions," Icasa said in a statement on Friday.
"The Authority (Icasa) welcomes the Speaker’s pronouncement that Parliament will investigate this matter. The Authority will liaise with Parliament on the outcome of the investigation. Should it deem it necessary, the Authority may also institute its own investigation into the matter," Icasa said.
Jail security
Signal blocking devices are available in SA and are used in some high security prisons, according to an expert.
"It is used in jails to block cellphone communication to the outside and will obviously be used where certain high level confidentiality is applicable," Dawid Jacobs, forensic solution provider with Strategic Investigations and Seminars, told Fin24.
The equipment that could have been used might have been similar to the indoor jammer distributed by Pinnacle.
The jammer has the ability to block all Wi-Fi and GSM signals typically used by mobile phones. It has an effect on frequencies from 800MHz to 2170MHz.
In terms of range, the device can block signals from 50m to 120m depending on the strength of the signal.
Given the modular design of blocking technology, a user could create various types of blocking that would match the experience of members in the chamber.(from fin24.com)
