What do you mean by UWB?

fading. The high bandwidth of UWB signal brings the enormous system capacity, because the UWB radio signal emission impulse pulse duty ratio is very low, the system has high gain and strong multipath resolution, so the system capacity is higher than other wireless technology. Because the UWB signal spread spectrum pr

Analysis of the UWB wireless protocol-the UWB wireless communication layer

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

Integrate Bluetooth and UWB to develop new wireless Spaces

. 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

Basic Introduction to wireless UWB technology

that the generated waveform occupies the bandwidth of several GHz. The wireless UWB technology is essentially different from the existing wireless communication technology. The current wireless communication technology uses a continuous radio wave, which is like a person watering the lawn with a pipe, the water in the pipe fluctuates continuously with the movement of manpower. Almost all wireless communica

Briefly introduces the advantages of wireless UWB technology

technology is much simpler, and it has a huge advantage in transmission rate and cost. UWB has the following features: 1. strong anti-interference performance: the wireless UWB technology uses time-hopping spread spectrum signals, and the system has a large processing gain. When transmitting, the system disperses weak radio pulse signals in a wide band, the outp

TM-UWB Technology and Its Application in wireless communication)

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

UWB: Bluetooth Terminator?

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

The new solution accelerates the verification of the UWB Physical Layer

common test method is to use a vector signal source. However, the popular vector signal source built-in IQ baseband generator generally only generate dozens of megabytes of modulation bandwidth capacity, for the MB-OFDM at least 528 MHz, more than GHz demand is inevitably unable to do. Therefore, the feasible solution is the combination of high-performance vector signal sources and high-performance arbitrary waveform generators.In terms of the probe method, all the basic components of MAC/PHY t

In-depth analysis of wireless UWB technical principles (1)

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
