Question

Cell phone jammers work by interfering with the signals exchanged between cell phones and nearby cell phone towers. As a result,

cell phones being affected by cell phone jammers do not receive communication signals from nearby towers.
How do cell phone jammers disable the communication between cell phones and nearby cell phone towers?
A.
Cell phone jammers reflect the signals emitted from cell phone towers away from cell phones in the area.
B.
Cell phone jammers absorb signals that are emitted by cell phone towers before they reach cell phones in the area.
C.
Cell phone jammers change the frequency of the signals emitted by cell phones and cell phone towers.
D.
Cell phone jammers transmit powerful signals at the same frequency as the signals used by cell phones and cell phone
towers.

Answer 1

The answer is D.

Step-by-step explanation:

Answer 2

D.

Cell phone jammers transmit powerful signals at the same frequency as the signals used by cell phones and cell phone

towers.

Step-by-step explanation:

Cell phone jammers are used for disrupting communication between the mobile phone and the cell tower.

Phones used radio-waves at certain frequencies to transmit and receive information through cell towers.

A cell phone jammer produce and transmits signals at the same frequency as at the of the tower. Thereby they mimic the signals they are supposed to connect with at the tower. This they cloud the legitimate signal produced at the tower.

They usually produce a scrambling irregular noise and are used for security purposes.
