The Protocol of the ultra-wideband wireless technology-the ultra-wideband wireless protocol. If you know about this technology, you must have some knowledge about this protocol. Next, this article mainly introduces the UWB wireless communication layer in the UWB wireless protocol. In the wireless access mechanism adopted by traditional wireless technology, the throughput changes with the channel usage. In

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 several centimeters of positioning accuracy. T

The wireless UWB technology is an alternative among the wireless technology families. Its uniqueness has become a key object of military research. However, since then, it has broad application prospects for common business areas. So this article will introduce the wireless UWB technology. Introduction to wireless UWB technology Wireless

radio technology, you can use an average power less than 1 MW to cover a few miles, or even use a low-gain antenna. It is particularly valuable that it has low Interference Characteristics and strong multi-path interference resistance to other wireless systems. It is easier to implement than to build a common spread spectrum system, with a low cost. It is precisely because of the above features that the UWB communication technology has been widely us

. Notable development trends include modifying the Protocol to increase the bandwidth of Bluetooth 2.0 + data rate enhanced version-EDR) and planning to bring Bluetooth and ultra-broadband technology to the Alliance recently. The next trend is bound to combine the advantages of the bluetooth wireless lan wpan with the data transmission rate of up to 100 Mbit/s for the UWB system.However, none of these measures can change the following facts: it is tru

The Wireless World is booming, and various wireless technologies have begun to compete. The wireless UWB technology has great advantages in both cost and transmission speed. Other advantages are described below. The focus of this article is to introduce the six advantages of the wireless UWB technology. The Ultra wide band is short for Ultra Wide Band. It is a non-carrier communication technology that trans

According to the internal structure of RFID tags, they are divided into active tags with battery (Tony Note: Also called active tags) and passive tags without battery (Tony Note: Also called passive tags) these two types. The Passive Tag uses the radio waves sent by the reader as the power to start the IC circuit. Therefore, it has the advantage of semi-permanent use, but the communication distance is shorter than that of the active tag. On the other

Antennas are rectangular, circular, and rod-shaped. Generally, the longer the communication distance is, the larger the size of the antenna. However, in actual use, when tags are attached to an item, even the RFID tags of the business card size are too large. In fact, the size and shape of the RFID tag in use need to be selected based on the communication distance. Currently, antenna materials include al

× Winding Process It is a process that combines an antenna and an IC loop to form a module. It takes some time to mount modules one by one on a thin board. Therefore, high costs are not suitable for mass production. However, compared with other manufacturing processes, the tag communication distance is improved. × Etching ProcessIt is a process of forming an antenna by etching aluminum or copper film on the pet Film Board. Figure 4 shows an item (using an etching antenna in an IC circuit). B

In the previous article, we have briefly introduced the basic concepts of wireless UWB technology. Now, based on the wireless UWB technology, I will give you a detailed analysis of its principles. Hope that you can find the information you need. Technical Principles of wireless UWB The most basic principle of wireless UWB
