After executing this command, the MyDemo AbstractionLayer PocketPC Next you will add two new files, one AssemblyInfo.cs, the other is Microsoft.Cell phoneDevices.AbstractionLayer.TMailMMS.PocketPC.cs. Seventh step, the newly generated AssemblyInfo.cs just move to the Properties directory, overwrite the original AssemblyInfo.cs file. Microsoft.Cell phoneDevices.AbstractionLayer.TMailMMS.PocketPC.cs file to the file all the Harness, modified TuxNet; cancellation of these two codes.
Motorola, Nokia, Ericsson cell phone early RXI Q signals are two signal lines (RXI, RXQ), and GD90 has four signal lines (DQ, DQX, DI, DIX), Ericsson T28 cell phone also has four lines (RXIA , RXIB, RXQA, RXQB). Motorola, V998, A6188, L2000, P7689 and other cell phone RXI Q signal integrated circuits in the house, there is no external pins, so it can not be measured with an oscilloscope waveform. GSM cell phone transmitter generally has three frames: the frequency of the transmitter with the transmitter, the transmitter with a transmitter and direct conversion circuit conversion transmitter. Emission process is as follows: digital voice processing circuit processing the resulting emission I, Q baseband signals to the demodulation circuit TXUQ modulated carrier signal, get modulated IF signal TXUQ launch. For TXFQ modulator output carrier signal from the VCO module IF VCO signal (usually from receiving two vibration signal). The customer asks for the strict inspection of Cell Phone Jammers .
Transmitting the modulated IF signal in the phase detector reference frequency with the transmit signal to compare to get a pulse includes the DC signal to send data to control the transmit VCO operation. Reference frequency signal transmitting the signal from the transmit VCO signal with an oscillator RXVCO mixing. Transmit VCO output signal the end of the launch (GSM900 frequency band 890 --- 915MHz or DCSl800 band 1710 ~ 1785MHz) amplified by the amplifier from the antenna to send out. Motorola, Ericsson, Samsung, Siemens and Panasonic cell phones transmit circuit have adopted this structure. The structure of the transmitter circuit stability, but the circuit is a little complicated. The group member should submit the weekly report of Cell Phone Jammers to the leader of technology group.
Transmitting a modulated signal is sent in: shot mixers, and RXVCO (or UHFVCO, RFVCO) mixing, the final transmit signal (GSM900 frequency band 890, - 915MHz or DCSl800 band 1710 ~ 1785MHz). This structure is simple, but the stability is poor, only the early Nokia cell phones (such as 8110,3810,6150,3210,7110, etc.) transmitter circuit adopted this structure. With the advent of new cell phones, some of the new cell phone use in direct conversion transmitter. Such as the Nokia 8210,8850,3310 phones. This receiver circuit shown in Figure 4-16. This transmitter circuit, logic circuit audio output TXI Q signals directly to SHFVCO signal (local oscillator circuit of this structure is generally referred to SHFVCO) modulation, the final transmit signal.  Cell Phone Jammers is in the direct charge of Vice Chief Engineer.
