Cell phone jammer is an electronic device that blocks the transmission of signals between the cell phone and its nearby base station. By using the same frequency as the cell phones, the radio frequency blocker creates strong interference to the communication between the caller and the receiver. It is efficient in blocking the transmission of signals from the phone networks, including UMTS, 3G, CDMA, GSM and PHS.

b=a is right because you add the (capacity) animal to the subject (dog)
