Cellphone jammers not enough to block calls from prisoners

The efficacy of cellphone jammers employed within the nation's prisons is insufficient in halting incarcerated criminals from communicating with individuals beyond the prison premises.
This is the view of senior prison officials who tell the Sunday Express that even though the signal blockers (which they say are operational) are used to block signals from cellphones within the prisons, other interception technologies are needed for the system to be effective.
Cellphone jammers are in use, yet their true effectiveness is only achieved when employed alongside other technologies like Wi-Fi jammers. This correlation has been observed in different jurisdictions, but its proper utilization is still pending in our context.


Incarcerated individuals will be equipped with cellphones and tablets; however, they will be unable to engage in direct phone conversations. Nonetheless, they can rely on the phone's data or, if they have access to a hot-spot device or a Wi-Fi box, they can make calls using social media applications such as WhatsApp, Facebook, and Instagram. Consequently, the issue of connecting with the external world still exists. Communication continues to take place.
“In other jurisdictions, you will see the cellphone jammers being used with other interception devices to determine the frequencies used by these devices, and then target those specific frequencies. If this is not done, then it’s almost like spinning top in mud,” a senior source in the Prison Service explained yesterday.
Moreover, the Sunday Express has revealed that the jammers, despite being utilized and operated within the Prison Service premises, are actually managed by a third party.
When questioned about the functionality of the cellphone jammers, Acting Prisons Commissioner Deopersad Ramoutar opted not to provide a direct answer. He justified his decision by stating that this information is privileged and falls outside the purview of the Prison Service.
The Sunday Express received information from other senior officials stating that they are still in operation.
A Wi-Fi box was one of the contraband items that were discovered and seized at the Maximum Security Prison in Arouca.
The officers were informed of crucial details that led them to the cells in the B Division of the prison.
In the course of the search proceedings, diligent efforts were made, leading the police to uncover and confiscate a bag located in a specific cell close to the toilet area. This bag contained 53 grammes of marijuana, along with cellphones and the Wi-Fi box.
In a different chamber, the police stumbled upon and confiscated a bag that held 104 packs of cigarettes and marijuana, weighing a total of 241 grams.
It was stated by two prisoners that they possessed the seized belongings.
On Friday, prison officers expressed their worries about the use of drones above penitentiaries. A senior officer emphasized the critical nature of this matter, stating that it is an issue that demands immediate attention.
The presence of an undetected drone, even just one, has the potential to cause a highly critical situation. This drone could drop weapons such as knives or firearms, posing a serious threat. While we have managed to seize contraband items like cigarettes, marijuana, phones, and chargers thus far, missing even a single drone could lead to a dangerous scenario within the prison and for the nation.
Ramoutar pointed out that the Prison Service has taken notice of an escalation in the utilization of drones around prisons, especially within the last year, and has implemented appropriate measures.
By utilizing the resources of various departments within the National Security portfolio, he declared that a significant portion of the objects thrown over prison walls were apprehended before reaching the prisoners.
