How Cellphone Signal Jammers (Blockers) Work

CELLPHONE SIGNAL JAMMERS are the newest threat to the success of the 2010 automated elections and the Comelec is alarmed. But how do cellphone signal jammers (blockers) work? Find out right here.

It was written in the papers that the Comelec said that it had received reports that a shipment of 5,000 signal jamming devices had entered the country. The agency emphasized that the cellphone signal jammers could be used by poll cheaters to delay the transmission of election results data to their advantage.

To understand how cellphone signal jammers (blockers) work, we picked up basic information from the experts at HowStuffWorks and this is what they posted:
Disrupting a cell phone is the same as jamming any other type of radio communication. A cell phone works by communicating with its service network through a cell tower or base station. Cell towers divide a city into small areas, or cells. As a cell-phone user drives down the street, the signal is handed from tower to tower.

A [signal] jamming device transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower. It's a called a denial-of-service attack. The jammer denies service of the radio spectrum to the cell-phone users within range of the jamming device.

On the other hand, we believe that it's not only the Comelec who should ensure that the May 2010 Philippine elections will be successful and fraud-free. We, as citizens bound by our constitutional right to suffrage, must once and for all be vigilant. Report to the Comelec crooks using these cellphone signal jammers.
