The meeting to analyze the market of cell phone jammer

RF technology is radio frequency identification technology, full name, English name is Radio Frequency Identification, referred to as RFID technology. RFID system consists of a complete reading device (Reader) with electronic tags (Transponder) composed of two parts. The action principle on the grounds of a particular reading device transmitting radio frequency energy to the unlimited tag, RFID circuitry to drive the internal identity code (ID Code) sent, readers can receive this status code after receiving the information for identification and . The special tag is battery-free, non-contact-free card, so not afraid of dirt, and the password is the world's only chip can not be copied, safe, long life. Reading device (Reader) with electronic tags (Transponder) transmit and receive RF signals is called coupling. The two basic types. The management personnel of the warehouse of cell phone jammer should lock the door of the warehouse of cell phone jammer .
Inductive coupling. Transformer model, through the space to achieve high-frequency alternating magnetic field coupling, based on the law of electromagnetic induction. Inductive coupling is generally suitable for medium and low frequency radio frequency identification system to work closer. A typical working frequency: 125kHz, 225kHz and 13.56MHz. Recognition distance of less than 1m, the typical role of the distance of 10-20cm. NFC (Near Field Communication) technology is representative of inductively coupled radio frequency technology, the frequency of 13.56MHz, the effective distance of 0-20cm. The marketing center of cell phone jammer is holding the meeting to analyze the market of cell phone jammer .
IResearch believes that the most powerful in the industry will become a leader in setting the standard for local payments, and mobile operators launched the technical standards more likely to succeed. China's mobile payment technology with more local choice. The current mainstream technology, there are three, namely: NFC, SIMPass and RF-SIM. Three criteria are NFC class technology, and SIMPass and RF-SIM is based on the traditional NFC standard, carried out some improvements. This makes the three techniques have a unique performance, which also had some advantages and disadvantages. IResearch believes that the current mobile phone near optimal technical solutions never appear.
