The current research direction of IrDA is how to solve the problem of line-of-sight transmission and improve the data transmission rate. NFC Technology NFC is a short-range wireless communication technology standard that is driven by Philips, Nokia and Sony and is similar to RFID (non-contact Radio frequ

near-range wireless communication technology. NFC, developed jointly by Philips and Sony, is a non-contact identification and interconnection technology that can be used in mobile devices, consumer electronic products, PCsAnd smart control tools for close-range wireless communication. NFC provides a simple, touch-based solution that allows consumers to easily and intuitively exchange information, access co

than, and most of them are used for access control and attendance assessment, currently, many enterprises use this type of access card. Because such cards canLarge distance workTherefore, the required field strength (1.15-5 A/m) is less than that of the proximity card (1.5 to 7.5 A/m ). ISO 15693-1 describes the physical layer ISO 15693-2 describes the RF power supply and signal interface. ISO 15693-3 describes conflict prevention and transmission protocols. C. iso18092 It h

Abstract:The development of the signal processing circuit of the infrared focal plane array is introduced. The basic structure, working mode and application fields of CCD Multi-Channel transmitter (CCD-MUX), time delay integrated CCD (TDI-CCD), MOS and CMOS multi-channel transmitter (CMOS-MUX) are described. Finally, two application circuits of multichannel transmission devices are provided. Keywords:Signal

NFC Definition Near-Field Communication ( English:Near Field Communication , NFC ), Also known Short-range wireless communication It is a short-distance high-frequency wireless communication technology that allows electronic devices to transmit non-contact point-to-point data and exchange data within 10 centimeters (3.9 inches. This technology evolved from contact-free radio frequency identification (R

Wireless Communication: Technology Integration to create the future Due to the application of close-range wireless communication (NFC), most of the applications involve personal privacy and financial security, including the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC) and the United Nations (UL) certification bodies, such as MIIT, have proposed a variety of security standards and specificat

body is more rounded and the thickness is reduced to 7.5 mm. Let's enjoy the look of the Phantom Pro 5. To sum up, we can know that the Phantom Pro 5 currently has a silver/gray/Gold/Silver black Three colors, this Pro 5 uses a 5.7-inch screen, and the screen is the standard ratio of 16:9. Thanks to the charm of the super narrow frame and rounded fuselage design, the feel of the size of the hand and the general 5.5-inch screen phone does not differ significantly. Does the Phantom Pro 5 have

The 802.11ac standard is mainly designed to provide high throughput in the 5 GHz band, in addition to bringing fast and high-quality video streams, it also provides almost instantaneous data synchronization jobs and backups for laptops, tablets, and mobile phones. Theoretically, this specification will achieve at least 1 Gbit/s of multi-site WLAN throughput and at least 500 Mbit/s of maximum single-link throughput. This is achieved by expanding the air interface concept adopted by 802.11n: wider

Although command execution requires the necessary code, the command executor provides the necessary support during command execution. For example, draw a Windows form with a text box. Some text must be added to the text box when a command is executed. But the command is an independent class, and it does not reference the text box in the f
