Why does Iot require 5 GB When the fifth generation of communication technology (5 Gb) arrived in 2020, engineers expected it to be able to process 1000 times the mobile data of today's cellular systems. Some people think that it will also become a backbone network of the Internet of Things (IoT), connecting fixed and mobile devices (such as fixed vending machines and automobiles) and become part of the new economic revolution. New Architectures, new communication technologies, and new hardware

coffee shop or a large department store, the owner only wants a login page, so I think there will be only one Wi-Fi solution for each venue ." Baker said operators that want to occupy part of the Wi-Fi market are scrambling to catch up. "But they encountered obstacles because they started from scratch. The Cloud and O2, our closest competitors, already have about 15 thousand Wi-Fi hotspots, And we have 4.5 million (including Fon access points ). In the past two or three years, we have significa

take a look at what can help improve the Wi-Fi performance of Enterprise WLAN. Disable 802.11b Data Rate In 2018, it was safe to assume that wireless devices running on your network have at least 802.11g capability. Even so, there are still many networks that allow the data rate of 802.11b, which may greatly reduce the speed of other devices connected in the 2.4 GHz band. In enterprise-level Wi-Fi hardware, it is easy to disable the 802.11b data rate. This will force wireless clients to connec

design milestones of 5g in 2018. After all, no one is willing to move around or see ugly antenna arrays with brick-based devices. Some companies worth attention in this field include Samsung, which has been promoting its work in the 5g miniaturization field since 2016, we will see the findings of Samsung at the Pyeongchang Winter Olympics in August. 4. forming a new gold rush In fact, the 2018 winter Olympics in Pyeongchang, South Korea was the first large-scale application of 5g. The Korean ca

content in the intermediate frequency information.The Fourier transform can be used to obtain the image spectrum graph:The image on the left is the original, and the right is the spectrogram.• the frequency of images is an indicator of the intensity of gray changes in the image, and is the gradient of the gray level in the plane space. such as: a large area of the desert in the image is a region of slow gray-scale changes, the corresponding frequency

The frequency domain enhanced Fourier transform in OpenCV has matured, and in his official tutorials document there is a complete example of getting a spectrum map, as follows:#include "opencv2/core/core.hpp"#include "opencv2/imgproc/imgproc.hpp"#include "opencv2/highgui/highgui.hpp"#include int main (int argc, char * * argv){Const char* filename = argc >=2? ARGV[1]: "Lena.jpg";Mat I = imread (filename, cv_load_image_grayscale);if (I.empty ())return-1

integrated network. In addition, due to the convergence, 5G can continue to use 4G, 3G infrastructure resources, and achieve coexistence with 4G, 3G, 2G. Huawei CTO Tong Wen said that 5G will provide super-capacity bandwidth, and the short-distance transmission rate is 10 Gbps, which is 100 times the current LTE. Due to the integration of various network technologies, 5g can also break the limitations of existing spectrum resources to achieve full

DTW is mainly applied in the isolated word recognition algorithm, used to identify some specific instructions compared to good, the algorithm is based on DP (Dynamic programming) algorithm on the basis of the development. The introduction of speech recognition here first introduces the framework of speech recognition, first we have a comparison of the template sound, and then need to intercept it contains the part that really belongs to the voice, this is called VAD (voice activedetection) voice

automatically recognizes sheet music, the results can be achieved by spectral sounding by the input spectrum. #In addition to the audible device (assuming it is done), the most important is the ability to read and interpret the spectrum. #analysis of their needs, the whole process can be divided into two parts:#translate the contents of a spectrum according to t

Visual perception of all color image, all have lightness, hue and purity three kinds of nature, these three kinds of nature is the most basic element of color. Lightness In the absence of color, the highest brightness of the color is white, the lowest brightness of the color is black, there is a light from the dark gray series. In the color, any kind of purity has its own lightness characteristic. For example, yellow is the most obvious color, in the center of the

5G has high performance, low latency and high capacity characteristics according to 3GPP definition, and these advantages are mainly embodied in millimeter wave, small base station, massive MIMO, Full-duplex and beamforming technology. Among them, massive MIMO and beamforming are closely related. 1, millimeter wave There are generally two ways to increase the transmission rate of wireless transmission, one is to increase the spectrum utilization and

Remember the experiment of sunlight through a prism? The white light passes through the prism and is decomposed into a variety of colors that gradually transition to the color spectrum, followed by red, orange, yellow, green, green, blue, purple, and this is the visible spectrum. It is clear that the prism separates the mixed things. Today's wireless network is like a bunch of white light, users do not see

Introduction to wireless network technology-Analysis of 4G stack system framework-4g stack system framework-this technology provides faster data rates and greater system capacity. The target peak speed is: 1 Gbps or more for low-speed mobile, hotspot coverage, and 100 Mbps for high-speed mobile and wide-area coverage. The above performance indicators mainly rely on two methods: Improving the spectrum efficiency and expanding the system bandwidth. To a
