What does wlan wireless wifi mean? WLAN and IEEE 802. 1 1, 802.1a, 802.1/b, 802.1/g.

(WLAN: wireless local area network)

Wireless local area network (WLAN) technology is defined in IEEE 802. 1 1 specification series. At present, this series includes the following four specifications: 802. 1 1 802.1a, 802.1/b, 802.1/kloc. All four protocols adopt Ethernet protocol and carrier sense multiple access/collision avoidance technology (CSMA/CA instead of CSMA/CD) to realize channel sharing.

802.11-Used for wireless local area network, using 2.4 GHz frequency band, with transmission rate of 1 Mbps or 2 Mbps；; It supports frequency hopping technology (FHSS) and direct sequence spread spectrum (DSSS).

802. The extension of11a-802.11uses the 5GHz frequency band and the transmission rate is 54 Mbps；. 802. 1 1a supports orthogonal frequency division multiplexing (OFDM) coding, but does not support FHSS or DSSS. 802. 1 1a is suitable for wireless ATM system, which is used to access the hub (aeshub).

802. 1 1b (also known as 802.1/high-speed or Wi-Fi)-802. 1 1 extension, using 2.4 GHz band, the transmission rate is/kloc-. 802. 1 1b is the revised version of the original 802. 1 1 standard, which realizes the function similar to Ethernet in a wireless way.

802. 1 1g- supports short-distance wireless transmission, uses 2.4 GHz frequency band, and the transmission rate is 20 Mbps to 54 Mbps. 802. 1 1g supports OFDM coding.

Phase shift keying (PSK) modulation has been used in 802. 1 1. 802. 1 1b adopts CCK, which supports higher data transmission rate and is not easily interfered by multipath propagation. 802. 1 1a adopts orthogonal frequency division multiplexing (OFDM), in which the data transmission rate can reach 54 Mbps, but in most cases, the transmission rate during communication is 6 Mbps, 12 Mbps or 24 Mbps. 802. 1 1 protocol stack structure

Introduction to WIFI

The full name of wireless fidelity is 802. 1 1b standard. Its biggest advantage is its high transmission speed, which can reach 1 1Mbps, and its effective distance is also very long. It is also compatible with various existing 802.1kloc-0/DSSS devices. Centrino, the most popular notebook computer technology this summer, is based on this standard.

IEEE (Institute of Electronic and Electrical Engineers) 802. 1 1b wireless network specification is a variant of IEEE 802. 1 1 network specification, and its maximum bandwidth is12Mbps, which can be adjusted in case of weak signal or interference. Its main features are: high speed and high reliability. In the open area, the communication distance can reach 305 meters, and in the closed area, the communication distance is 76 meters to 122 meters, which is convenient to integrate with the existing wired Ethernet and has lower networking cost.

Wi-Fi？ Wi-Fi, Wi-Fi? Technology, like Bluetooth technology, belongs to short-range wireless technology used in office and home. This technology uses a frequency band of about 2.4GHz, which is currently a wireless frequency band without a license. At present, there are two available standards, namely IEEE802. 1 1a and IEEE 802.11b. This technology is favored by manufacturers because of its own advantages.

What's the difference between MBA and EMBA? What do they mean? MBA stands for Master of Business Administration in English and MBA in Chinese. MBA is the product of market economy. It trains high-quality and leading professional enterprise management talents to master multidisciplinary knowledge and management skills such as production, finance, finance, marketing, economic regulations and international business, and has strategic planning vision and keen insight. MBA degree is a degree that pays attention to the cultivation of compound and comprehensive talents, and it is a degree that ability cultivation is more important than knowledge transmission. It teaches "management" facing actual combat, not "management" focusing on research. It requires its graduates to have adaptability, predictive ability, comprehensive ability and organizational ability to develop and win in the ever-changing world market and international competition. Its course content involves management, economics, finance, finance, law and so on. Ability training not only pays attention to organizational and leadership skills, but also involves eloquence-based communication skills, the ability to grasp the overall situation, think sharply, judge and deal with problems.

MBA is the first widely accepted international degree. MBA is a graduate degree, which is the most needed quality, knowledge and academic standard for MBA. Generally, you have to have the first degree to enter MBA study, except for a few people with rich professional experience.

MBA is a degree with work experience. After three years of professional experience, it is regarded as a career accelerator or a means of transformation.

The MBA course covers all the main functions of modern management, such as accounting, finance, marketing and sales, logistics (production) management, information system management, law, human resource management and so on. It also provides basic economic and quantitative analysis. The course is very comprehensive, including industrial and commercial policies and strategies. In addition, the course also requires students to acquire knowledge and skills of integrating theory with practice, such as decision-making ability, teamwork, leadership ability, entrepreneurial potential, negotiation ability, communication and reporting ability. In the process of learning, students should have elective preferences and choose majors.

The minimum study period of MBA is full-time one year or corresponding on-the-job study time weight. The MBA needs at least 400 hours of classroom study, and the whole course needs at least 1200 hours of personal homework. MBA programs require a thirst for knowledge and personal dedication and efforts.

Entering the MBA program must go through a rigorous screening process to ensure that only those qualified candidates can get an MBA degree. All students must pass strict examination, marking and grading to ensure that the learning objectives can meet the standards of MBA degree.

Not all business schools can meet these standards. If they can't meet these standards, they can't be called a real MBA.

The difference between MBA and MBA

First of all, the application conditions are different. As long as the MBA meets the national unified registration conditions, that is to say, both fresh graduates and on-the-job personnel can apply for the exam. To apply for an MBA, one must have three years or more work experience after graduating from university; Persons with 5 years or above working experience after graduating from junior college; Persons who have obtained master's degree or doctor's degree and have two years or more work experience (graduation date to admission date).

Secondly, the examination subjects are different. The entrance examination of MBA should take the entrance examination of 62 pilot universities in China, and the entrance examination subjects are politics, mathematics, English, management, Chinese and logic.

Third, the difficulty of the test questions is different. Generally speaking, it is more difficult to take the unified national entrance examination for MBA in English and mathematics than MBA. However, due to the sharp increase in the number of MBA applicants in China in recent years, the competition has become increasingly fierce.

Fourth, the training methods are different. MBA students are generally trained by the state, with a monthly subsidy of more than 200 yuan, as well as entrusted and self-funded students. All MBA students are self-funded or entrusted by the company.

Fifth, the training objectives are different. The training goal of MBA is excellent entrepreneurs and practitioners. For example, MBA graduates from Tsinghua University Institute of Economics and Management should be competent for middle and senior positions in industrial and commercial enterprises and economic management departments, and they are compound talents who can adapt to the fierce competition in the future society. The MBA program of Guanghua School of Management of Peking University is aimed at multinational corporations, large state-owned enterprises, large private enterprises and large financial institutions. Guanghua School of Management is committed to helping the management team of multinational companies localize, the management of national enterprises internationalize and the management of private enterprises modernize. Therefore, MBA courses pay attention to practicality. The master of business administration should not only train the actual managers of enterprises, but also attach importance to the theoretical education of management science for students and train successors for the development of disciplines.

Under normal circumstances, MBA graduates have a solid theoretical foundation, and MBA students can quickly adapt to the actual work of enterprises because they have considerable practical experience before entering school and pay attention to the combination of practice in the learning process.

The full English name of EMBA is Executive Master of Business Administration, which is literally translated as MBA for senior managers. It was initiated by the School of Management of the University of Chicago. EMBA students are generally recommended by companies, and concentrate on classes in their spare time, with a wide range of courses and a balance between theory and practice. Its essence is a kind of on-the-job training with a degree, which is of great significance to managers who have not an MBA degree but have been promoted to the middle and high levels of the company.

In foreign countries, if you want to study MBA, you need to take the GMAT entrance exam. However, only 765,438+0% schools need GMAT scores for EMBA, with an average score of over 530, while overseas students only need TOEFL scores of 550. However, this does not mean that EMBA admission is easy. Schools pay more attention to students' work experience, work ability, expert recommendation letters and interview results.

EMBA students require work experience, and many of them can get financial support from the company. In the United States, EMBA students come from various companies, such as manufacturing department, finance department, trade department and * * * department. In Canada, EMBA students come from * * * departments. Their average education age is 38 years old, 96% of them have obtained a bachelor's degree, and they generally have 10 years of management experience, with an annual income of $78,000. 60% EMBA programs offer courses in international business, trade and finance. There is also the 10% project, in which the school will organize students to go abroad for a week-long academic visit on an international issue. Some colleges have set up a series of celebrity lectures, inviting successful entrepreneurs, officials and celebrities to give lectures to students and communicate with them.

In foreign countries, further study is regarded as an investment. Students who study EMBA hope to invest tens of thousands of dollars in two years, and it should not be a problem to get a return after studying. And Amy. People with BA study background and years of work experience are very popular with employers.

At present, the tuition standards of different schools vary greatly, with an average annual tuition of $65,438+$065,438+$0,000 per person, and the tuition of famous schools is as high as $25,000.

Under the background of global economic integration, especially since China joined the World Trade Organization, China enterprises are facing more complicated competition and more severe challenges. Therefore, it is more urgent for top managers of enterprises to systematically learn management knowledge and improve their management ability. The State Council Academic Degrees Committee recently approved 30 universities in China to offer executive master of business administration education for the first time, which is of great significance for training senior managers and improving the EMBA education system.

EMBA is a special form of MBA degree education, and their positioning is different. Because the MBA entrance examination requires foreign languages and mathematics, it sets a threshold for those executives who have rich management experience but have left the examination environment for many years. At present, the MBA in China is younger, and the high test scores are often young people who have graduated from college for about 3 years and have strong test-taking ability. The written test and interview of EMBA entrance are organized by the training unit itself, and the threshold is greatly reduced. Of course, this does not mean that any boss or boss can go to EMBA. Recently, Tsinghua University turned down a boss who was willing to spend $250,000 to study but didn't meet the requirements. According to national regulations, the on-the-job senior managers of large enterprises must have a bachelor's degree or above and have more than 8 years of work experience (including more than 4 years of management experience) before they can register. There are also great differences between the two in teaching mode. MBA mostly adopts the mode of "teaching+case analysis+team discussion", while EMBA pays more attention to the combination of courses and students' practical experience on the basis of inspiration, so it is more suitable for senior managers who are actually fighting in shopping malls. Nanjing University limits the number of EMBA students to 100. About 50% of the foreign teachers will be professors from Harvard and the University of Southern California, and 80% of these foreign teachers are from China, in order to have more "interaction" between students and teachers.

The EMBA literally translates as "executive master of business administration". March is the golden period of EMBA enrollment, and all EMBA programs are trying their best to make applicants "spend money like water and attract people". Which EMBA is right for you? Classifying and refining these EMBA programs will help readers polish their eyes and choose carefully.

EMBA needs at different price levels are different.

The "value" of EMBA has always been the most concerned topic, and some training institutions have begun to play price cards to attract students of different levels, and some "private" EMBAs have been playing low prices. Talking about the reasons, Shao Ming Lu, chairman of Beijing Guanghua Management Research Center, said that the market for middle and senior professional managers is below 654.38+10,000 yuan, and these people have great room for improvement and strong demand for their own charging. However, "time-honored brands" such as Peking University, Tsinghua and Fudan still maintain high prices, and Fudan's EMBA even raised the price. They are aimed at the relatively stable group of senior managers in large enterprises, so the price can also remain stable.

The characteristic EMBA classified by major is more popular.

Some EMBA training institutions offer "featured" EMBA courses according to hot industries in the market. Because the course is set in a hot industry, it gives people a sense of "following the fashion". When interviewing Zhou Huajun, the head of EMBA of China Europe International Business School, the reporter learned that EMBA is a training course aimed at the comprehensive ability of senior decision makers, and there should be no obvious tendency according to international trends. However, some hot industries in China are developing rapidly, which are closely related to the international community. Objectively, they have a demand for EMBA, so it is appropriate to "customize" a directional EMBA for them.

EMBA plays a "brand" role in international cooperation in running schools.

It is a "popular trend" in this market to cooperate with foreign universities to run EMBA. But how do domestic universities choose their partners? Are there any corresponding standards and conditions? Wang, head of Peking University's international MBA program, told reporters that a key factor in choosing a partner institution is to ensure that students get an authoritative EMBA diploma. Because world-renowned business schools, such as Harvard, will not cooperate with other institutions with their famous EMBA programs. In other words, even if there are EMBA programs of brands such as Harvard in China, they can only get a course completion certificate, not a diploma. If students spend hundreds of thousands of yuan in tuition fees and finally can't get the authentic certificate, it's very worthwhile. Therefore, how to ensure the gold content of the EM-BA certificate is the most important selection condition and cooperation basis for Sino-foreign EMBA cooperation projects.

Generally, because new houses are not decorated and it is convenient to cut walls, they all choose to use concealed clothes. However, the room that has been decorated can't destroy all the decoration in order to install a socket, so exposed accessories are often installed. Just punch holes in the wall and fix them with expansion bolts, which is convenient to install.
