UWB technology is a new kind of wireless communication technology. It is directly modulated by impulse pulses with very steep rise and fall times, so that the signal has a GHz magnitude of bandwidth. Ultra-wideband technology solves the major problems of communication, which is not sensitive to channel fading, low power spectral density, low interception capability, low system complexity, and can provide se

Will UWB replace bluetooth technology? At least for the moment, the answer is no.First, they have different application fields. Bluetooth technology is widely used in PDA, mobile phone, printer, notebook and other terminal devices in the 2.4GH ISM band that does not need to be applied. The communication speed is usually below 1 Mbps, and the communication distance can reach 10 meters or more, while the communication distance of the ultra-broadband tec

Ultra-Wideband Wireless Technology is favored by more and more emerging wireless technologies due to its high transmission rate, low power, and small scale features. However, its very high modulation bandwidth (usually higher than 500 MHz) and relative bandwidth (> 20%) pose many challenges to the development and testing of the ultra-wideband product. The traditional general testing method is insufficient i

This article describes in detail the origins of the ultra-wideband wireless access technology, developed from the wireless UWB technology, that is, the pulse radio technology. It is used in a broader field and is integrated with our daily lives. It not only facilitates entertainment and work. Ultra-Wideband Wireless Ac

vulnerability, and to update the product as soon as possible. If the vulnerability is more serious and cannot be updated from the vendor, careful consideration should be given to disabling the device or protecting it with additional security measures. Background information Bluetooth is another important wireless LAN technology. The technology standard based on a small range of wireless connections is a

by jumping zigzag-shaped dances. ZigBee can be said to be Bluetooth with Shineti, it uses 2.4 GHz band, using frequency hopping technology. Compared with Bluetooth, ZigBee is simpler, slower, less power and less expensive. Its basic rate is 250kb/s, when reduced to 28kb/s, the transmission range can be extended to 134m, and obtain higher reliability. In addition, it can be networked with 254 nodes. Can better support gaming, consumer electronics, instrumentation and home automation application

developing, its application in addition to the traditional sense of communication, but also to the home network, industry, transportation, commercial and other areas of extensive penetration. UWB, as a kind of ultra-high speed short-range wireless access technology, has been supported by the Giants such as Intel. RFID-related products and solutions are also emerging. Ultra-wideband

I have made a lot of introductions and descriptions in the previous articles on the ultra-wideband wireless network. Therefore, we must have some knowledge about the ultra-wideband wireless communication layer in the previous ultra-wideband wireless protocol. Next, we will continue to look at the media access control layer of the ultra-wideband
