Cellphone jammer? hindi ba ito lumalabag sa karapatang pantao at privacy? kung ito ay nakakatulong sa mga may-ari ng negosyo halimbawa sa isang opisina na may maraming tauhan, ito nga ay maganda pero paano naman ang mga KARATIG na mga opisina na maaring maapektuhan nito? at higit sa lahat kapag malapit ito sa Ospital? Ito ay nakakahadlang sa mga gamit na elektronik sa mga ospital, tama ho ba? Ito ba’y aprobado ng Philippine NTC board?

hi. im a student currently proposing this cellphone jammer as our group’s project proposal. to answer the queries of “Taga_usisa”, this device has a finite range. i think the jammer presented here has a maximum range of 10meters. thus, for those who wish to have this must secure his jammer in a location where he desires to block signals. our group wishes to propose this jammer for reasons such as prevention of academic cheating, one measure in implementing library discipline, improper usage of cell phones in conferences, halls and other formal gatherings. with regards to the hospital issue, like any other item sold to the public, it can also have a wrong contribution depending on the CONSUMER’S INTENTIONS. but of course it is improper to place this device in hospitals,police and fire stations, and other places where communication is important. i came across with an article discussing the legality of this device and it was yet to be approved because basically the significance of the first jammer invented was for military purposes. it was never thought to be used commercially.

hi there kelly. interesting company you have there. well, the circuit components posted here are pretty hard to find and i dont have any idea how much this actually costs. one thing certain is that it’s not available in our country. i think that was what “Medel” here was trying to say. since i myself is also working on this as my project, do you have these components for sale from your company?? do you accept orders?? and lastly, with regards to the micro stripline, do you have it too?? i’ll wait for your post. thanks alot for showing up on this site.
