PART IX. SCANNING TO FIND THE ESN/MIN PAIR Well if you haven't guessed by now, the mobiles ESN and MIN must match in the switch or no go. This is required for billing purposes. If one had the ESN and the mobile phone number (MIN), he could call anytime and anyplace without fear of a trace - let alone a bill. The ideal setup would let you listen with a scanner to the reverse control channel, record and display heard working numbers and ESN's, and recall them as one needs to make calls. This would be it, but we are not quite there yet. But some of the hard work has already been done for us. All the aforementioned codes are sent in hex, in NRZ code (phase-key shifting), when a cellular subscriber places a call. But guess what? All phones have an NRZ receiver and transmitter built right into them. All that has to be done is to have a receiver on the reverse control channel, recover the other subscibers data and save it or print it out. Cellular phones operate on a full duplex channel. One frequency is used for transmission from the base to the phone, while another is used for transmission from the phone to the base. The base frequencies are always exactly 45 MHZ higher than the phone frequency, and both of these are incremented by 30 KHZ as the progression of channels increases from Channel #1 to Chanel #1023 (NOTE: There are no channels between 800 and 990). With some systems (not all) the cellular transmission is received by the base and retransmitted on the base frequency. When this is done, a scanner can listen to both sides of the conversation by simply monitoring the base frequency. When this is not the case, two scanners set 45 MHZ apart will work. Here is a list of all Cellular Frequencies: Non-Wireline Wireline Channel Tx Freq Rx Freq Channel Tx Freq Rx Freq Number Mhz Mhz Number Mhz Mhz 1 870.03 825.03 334 880.02 835.02 2 870.06 825.06 335
