Many people are concerned about WiFi wireless transmission speed, in addition to network bandwidth and hardware performance, the location of the router is also a very important factor, sometimes for the router to find a good home, do not spend a penny can improve WiFi wireless transmission rate. Carefully siting a good home for the router First, the location and placement of routers is the most basic (and

Dji Data Transmission considerations When using the DJI Mobile SDK and the DJI onboard SDK for data transmission, the demo from mobile device to onboard device was quickly implemented in DJI. But from onboard to mobile but tried many times can not be achieved, later, read a blogger's article, finally found the reason. reason: the transmission from onboard to mo

Communication of remote measurement and control terminals in water supply SCADA system my company used to be through wireless digital radio to achieve, due to the external interference is too large, too high temperature prone to cause frequency deviation, resulting in frequent data is not received, with the water supply network remote detection and monitoring technology of the continuous development and progress, Now the popular CDMA or GPRS wireless communication in the stability or accuracy of

With the development of technology, the product needs to improve the data transmission speed. The data transmission mode of the IDE interface hard disk has undergone three different technological changes, from the initial Pio mode, to the DMA mode, and then to the ultra DMA mode. Pio ModeThe English spelling of PIO is "programming input/output model". Pio mode is a data exchange mode that reads and writes d

Sometimes in the backup or synchronization with a large number of files (such as a few GB or dozens of GB of database directory, log directory), the direct SCP takes longer, although the first compression and re-transmission can be decompressed, the amount of data transmitted is really reduced, but compression and decompression will also take a lot of time , the overall effect is not satisfactory, yesterday night whim, due to previous experience in st

In today's era of rapid network development, routers play an important role. Because the router acts as a relay system in the network layer,Provides a routing and forwarding function for data between the third-tier networks. Therefore, the functions, functions, and basic configurations of routers must be mastered as members of the IT industry.In the following, we will make a brief analysis on the vro from two aspects: how to set up the simplest network environment in the experiment, common situa

The two remote transmission technologies have different advantages and disadvantages: fiber network topology is undoubtedly the first choice in terms of performance, but it is more economical to use IP addresses or the existing network topology, to make full use of the high-speed IP network and existing communication links, you must consider both fish and bear's paw.The communication link between the local and remote disaster recovery ends is an impor

I. Preface in the past 20 years, Internet, mobile communication and multimedia communication have achieved unprecedented development and great commercial success. The convergence of mobile communication and multimedia technology is accelerating. research results in network architecture, low-power integrated circuits, powerful digital signal processing chips, and efficient compression algorithms are emerging. Video Image Coding and transmission technol

After learning some basic FTP knowledge, Let's explain the FTP data transmission mode. This is also an important process to master this part of knowledge. I hope you can understand this knowledge clearly. Among many network applications, FTP File Transfer Protocol has a very important position. Software resources are a very important resource in the Internet, and most of the various software resources are stored on the FTP server. Like most Internet s

Many of our friends have found that our actual wireless router transmission rate is not as fast as described above. Why? Is it a false identification made by a merchant? Otherwise, let's take a look at the article for details. Wireless LAN, also known as WLANWireless LAN), has become a networking method adopted by more and more users. Wireless Network installation is very convenient and does not require rewiring. Therefore, it will not damage the orig

Wireless LAN technology has gradually developed and matured, but in the process of use, the factors affecting the transmission speed are also different. What problems should be solved in terms of software and hardware? Wireless LAN, also known as WLAN, has become a networking method for more and more users. Wireless Network installation is very convenient and does not require rewiring. Therefore, it will not damage the original decoration of the home.

Using Streaming Media Technology for video and audio transmission on the network Author: Zhang Cheng Release Date: 2000/12/05 Abstr: This article outlines the definition, principles, and development status of streaming media technology, and introduces how to use streaming media technology to spread audio and video information over the networ

Although the old left to see the host and the purchase of Linux VPS host is still relatively many, but most of them are limited to the general Internet or set up a simple site use. However, Linux VPS host the actual use of more than these, we can be used to build a specific project environment, and some are used to build remote client brushes, but also for foreign exchange projects, more used to install transmission for download purposes. Yesterday,

Many friends have found that our actual wireless router transmission rate is not as fast as the product introduction, what is the reason for this? Is it the false logo that the merchant makes? In fact, the real reason is to see the article to understand the specific. The Wireless LAN, also known as the WLAN (Wireless LAN), has become a networking method for more and more users. Wireless network installation is very convenient, do not need to rewirin

Wavelength Division Multiplexing Technology 1 Wavelength Division multiplexing Technology Wavelength Division Multiplexing (WDM) refers to the simultaneous transmission of two or more optical wavelength signals through different optical channels in the same optical fiber, known as the Optical Wave Division multiplexing technology. Wavelength Division multiplexing includes frequency division multiplexing and wavelength division multiplexing. There i

network history, the International Organization for Standardization (ISO) and the International Telegraph Telephone Advisory Committee (CCITT) jointly published a layer-7 Reference Model for Open System Interconnection. Network processes in a computer operating system include application requests (at the top of the protocol stack) to network media (bottom). The OSI reference model divides functions into seven discrete layers. Figure 2.1 shows the OSI layered model. 　　 OSI Layer-7 Reference Mod
