The company has issued the new manufacture plan of Cell Phone Jammers .
Receive SMS with PDU format: the wireless standard used WAVECOM module can be set to receive two different modes: direct serial port receive and through the Sim card to receive a direct serial port to receive: You can use the AT command: AT + CNMI = 2,2,0 , 0,0 + <CR> set, a short message with it, without a Sim card, write directly to the serial port (if port is not open at this time, the short message may be lost). Using this model, you need real-time processing serial information to the ten CMT <PDU >, when receiving the message, just follow the PDU mode decomposition and decoding can be obtained by calling cell phone <PDU> number and short message content. Received by SIf card: You can use the AT command: AT + CNMI = 2,1,0,0,0 + <CR>, which is the default setting, take the initiative to read Sim card SMS (recommended use of the parameters). The effective covering range of the shielding signal of Cell Phone Jammers is 3 or 4 rooms.
Using this model, you need to receive text messages through the Sim card, you should first get a new short message to the notification message that monitoring serial + CMTI <index number of new SMS>, then use the following Al. PDU mode decomposition and then return pack can be obtained by calling decode cell phone numbers and SMS content. In the production and management practice, there is growing recognition that the decision of an enterprise, a community development capacity, and not primarily machinery and equipment, but rather people have the knowledge, wisdom, talent and skills. Ultimately, all economic activities are carried out by people. Therefore must establish a man-made "this" business philosophy, through the efforts of all members, to create brilliant performance of enterprises. The quantity of Cell Phone Jammers being installed should be reduced.
Dissertation strike, and no relief, because the more educated feel to write more shallow, but fortunately all the way to write is a process of learning and growth. Smooth paper now finalized, drink from the source, special thanks to Professor mentor, from the topics of the framework, from writing to modify, pour all the hard work of teachers, but I still did not work hard enough to write better, deeply grateful while only feel ashamed. SMS short message service as a basic GSM network business has been more and more system operators and system developers attention to the GSM network as the wireless data transmission network, can be very optimistic about the prospects for the development of various types of applications . This paper presents a small embedded SMS Chinese / English SMS interface design, and detailed discussion of PDU mode SMS messaging software format and decoding Chinese design. There is no need to install Cell Phone Jammers on the outer wall of every floor.
SMS (Short Message Service) SMS service is GSM (Global System for Mobile Communication) system to provide a GSM terminal (cell phone), with through service centers (Service Center) for the application of text messaging service, which service center complete information, storage and forwarding. GSM short message service as a basic network service, has been a growing number of system operators and system developers attention, based on a variety of applications of this business flourished. The installation method of offset distribution of Cell Phone Jammers at sides should be adopted according to the actual situation in the building.
