Take care of these pitfalls when buying wireless routes: Gigabit network ports and 5 ghz are the most critical, Gigabit 5 ghz
315 is coming soon. Various consumer rights protection events have become the main character, and counterfeiting is a theme that has never changed for 315. Today, let's talk about text games printed by wireless router manufacturers on packaging. When selecting a wireless router, we
Why 802.11ac will kill the 5 GHz Wi-Fi band
I took the opportunity during a recent briefing call with Qualcomm atheros (QCA) about its new 802.11ac devices to dig into some of the technical details behind 802.11ac. I'm gglad I did, because I learned a fewThings about the new higher-speed wireless standard that shoshould be more widely known.
As you may know, 802.11ac is5 GHz onlyStandard. The reason for
Different countries and regions have different radio management regulations (RegulatoryDomain), and there are also different rules for the division of ISM5GHz frequencies. RegulatoryDomian has three major families: the FCC represented by the United States, ETSI represented by the European Union, and TELEC, once again a maverick in Japan (both in the cellular network and WLAN, japan has always been a weird existence ). China adopts ETSI regulations. The specific frequency band management is diffe
In 70 million, the media reported that China Unicom plans to invest yuan to build a WiMax test network in 21 provinces with the right to use the GHz band. In this regard, some insiders told Netease technology that, the feasibility of large-scale network construction with WiMax technology in the 70 million GHz band is very low. The investment of Yuan is also too small for the trial network scale in 21 provin
A new wireless LAN technology has been developed by scientists at the karsruer Institute of Technology in Germany, breaking the WiFi network data transmission speed record, allowing users 1 km away to download data at a speed of 40 Gb per second, this is equivalent to 10 HD movies with a length of 2 hours.
The rapid advances in the transmission speed of wifi not only benefit from cutting-edge hardware devices developed by scientists at the karsruer Polytechnic Institute, but also because they u

I believe that today, when wireless networks take off, we also have some knowledge about General Wireless Access Technologies. This article briefly introduces the composition and functions of the GHz wireless access system. I hope this article will help you.
3.5GHz Wireless Access System's general components and functions
The 3.5GHz Wireless Access system is generally composed of three parts: the Central Station (base station), the remote station, and
Bill Gates predicted that the CPU clock speed would reach 10 GHz [Source: Driver house] [Author:] [Time:] less than a year after the announcement that he was about to leave his self-created Microsoft empire, bill Gates planned the prospects and opportunities Microsoft is facing. Gates said there are currently six industry trends that will directly determine the direction of Microsoft and its product strategies over the next few years. What is more unu
If you only know the concept of CPU, then it is impossible to understand the CPU topology. In fact, in the NUMA architecture, the concept of CPU is from big to small: Node, Socket, Core, Logical Processor. With the development of multicore technology, we encapsulate multiple CPUs together, a package commonly referred to as a socket. Where the physical processor is plugged in, it looks like this: Each core

The program counter, the task's variables, and the CPU registers (including the Status flags). Program counters, task variables and CPU r
Java uses the annotation processor to generate code-Part 2: annotation Processor
This article is part 2 of my "using annotation processors to generate code for Java" series. In the first part (please read here), we will introduce Java annotations and several common methods.
Now, in the second section, we will introduce annotation processors. This includes how to create annotation processors and how to r

When you have a additional SSD, you can use a VSAN to transform the local storage into redundant shared storage. The server runs pretty quiet, so you can run it near your desk.Shopping Guide

I will upload my new book "self-writing processor" (not published yet). Today is the tenth article. I try to write it every Thursday.
This chapter describes how to implement the openmips processor for teaching. This chapter provides a blueprint for the openmips System for the tutorial version. First, it introduces the design objectives of the system. It details the 5-level pipelines implemented by the ope
The annotations in Java are a magical thing that you don't know yet. You can see the custom annotations (Annotation) for the next hour. Now a lot of Android libraries are implemented using annotations, such as butterknife, we do not want to learn, we learn the note processor, we try to write a simple similar to the butterknife of things to bind the control.What is an annotation processor?

Thread. UncaughtExceptionHandler is a static internal interface of the Thread class. This interface has only one method:
Void uncaughtException (Thread t, Throwable e), where t represents the Thread with an exception and the exception thrown by the e-table.
If an unhandled exception is thrown during thread execution, the corresponding unhandled exceptio

So what is the difference between the length of the CPU pipeline?The key lies in that the pipeline length is not a simple repetition. It can be said that it refines the work at each level, so that the work at each level is simpler, therefore, in the "10-level" mode, the time required to complete each level of work is significantly faster than that in the "5-level" mode. The slowest (and most complex) "level" structure determines the speed of each "level" in the entire pipeline-Please re
