No matter where you go, you don't need to look for network cables and "hot spots". You can use your digital devices such as laptops and mobile phones to access the Internet at any time. Can this be achieved? As WiMAX applications get closer, the convenient wireless communication you're looking for will become a reality, and wireless applications that you didn't expect will be popular. WiMax technology was named one of the coolest tomorrow's technologies in the world by Forbes magazine in 2004. In the not-too-distant future, the application of this technology is likely to be all-encompassing and omnipresent like "lace news". . Today, with Internet applications all over the world, more and more people need to go online anytime, anywhere, but now this requirement is not easy to be satisfied. If you want to go online at any time, you must get rid of the constraints of the line. At present, the most commonly used wireless communication standard is Wi-Fi, which is the 802.11 standard, which means "wireless compatibility authentication." As a current wireless transmission specification, Wi-Fi supports data transmission rates of up to 11 Mb/s and is a short-range wireless technology used in offices and homes. In general, if you buy a product with this logo, you can use them to easily set up a wireless LAN. In fact, Wi-Fi has always been a technology that many companies favor when building their own wireless LANs. However, although Wi-Fi seems to be better than the costly 3G enterprise network, Wi-Fi technology can only cover the access range of 30 meters to 100 meters, so now when you are at the airport or coffee When a place such as a hall is connected to a laptop computer, it needs to be implemented within the "hot spot" range. The birth of WiMAX will change all of this. WiMAX means "global microwave access interoperability", which is a wireless metropolitan area network technology based on the IEEE 802.16 standard, and the data transmission speed reaches 7575 mbps. With WiMAX technology, wireless networks can be established between large cities, because WiMAX can provide wireless broadband access services to fixed stations within 50 kilometers, which can basically cover the suburbs. This network coverage area is 3G towers. 10 times; WiMAX can also provide the same access services for mobile devices ranging from 5 to 15 kilometers. Therefore, WiMAX can connect Wi-Fi "hotspots" to the Internet to achieve broadband access for the last mile. Although WiMAX is not a real device, it is just a specification, but it is one of the few technologies that have the potential to fundamentally change the way people communicate. Because WiMAX can make wireless Internet access broadband, it can establish high-speed connections in more than 50 kilometers, which means that a small city can cover a large city with such a small number of antennas. Such a network communication world will be extremely convenient and cheap. . Initially, WiMAX was expected to be used as a replacement for DSL broadband, capturing a long-range signal with a fixed antenna. However, it was quickly discovered that the use of WiMAX cards for laptops allowed you to connect to broadband almost anywhere, and the era of true free networking came. At the end of August, Airspan Networks, the first to introduce WiMAX equipment, said it would conduct trials in the US and Japan in addition to the WiMAX trial in the UK. The first commercial WiMAX service will be launched first in Japan. However, before this, people have already outlined the actual picture of WiMAX technology application. If the farmer John has a vineyard in California, he can install a sensor on each grape to monitor the growth of the grapes and collect data such as air humidity, temperature, wind power, etc., and the data will be Concentrate and transmit to the data center via Wi-Fi network, and then analyze the grape growth by related software in the data center. When John was near the vineyard, he could use a computer to retrieve information from the data center, check the conditions of the vineyard, and decide what to do. And when John is in another distant city, he can also take the notebook or use his mobile phone to connect to the data center through WiMAX's network service, so as to master the details of the vineyard from a distance. Once something goes wrong, he can fully interpret the various data sent by the vineyard's sensors, determine what to do for the vineyard based on the data, and then send the relevant orders to the vineyard workers to perform. All of this communication will be timely and convenient, and it will not be troublesome in operation, thanks to the invisible network laid by Wi-Fi and WiMAX. The beautiful application prospects have attracted many manufacturers to develop various applications around WiMAX. At the same time, the commercial process of WiMAX is making great strides under the promotion of WiMAX Forum. In Europe, the WiMAX Forum and the European Telecommunications Standards Institute formally signed an important standard interoperability agreement to ensure that wireless metropolitan area network technology has a single global standard. The program aims to achieve full compliance with wireless metropolitan area network technology compliance standards by providing funding and resources - these specifications are based on IEEE 802.16-2004 and the European Telecommunications Standards Institute's BRAN HiperMAN standard. Although the initial hope is that WiMAX can be a replacement for DSL broadband, the subsequent facts prove that the WiMAX technology standard was not designed to replace DSL and 3G. On the contrary, WiMAX is also looking forward to the success of 3G, because WiMAX is essentially a standard set for next-generation networks. If 3G is successful, WiMAX will be able to provide users with more powerful broadband capabilities, in DSL and 3G. In addition, WiMAX is able to provide a more feature-rich solution that is currently unknown. WiMAX and other communication technologies can complement each other, which also gives it more room for development. In 2007 and 2009, when the rate reached 10 Mbit/s or more, the core technologies of 3G and WiMAX are still quite consistent. The value of WiMAX is to realize lower-cost broadband access from now on, so that non-core cities can also Enjoy the convenience of mobile broadband. At present, fixed antennas based on WiMAX technology are expected to appear, and mobile portable cards are also likely to enter the market in 2006 or 2007. The initiator of WiMAX technology, Intel Corporation, has reached an agreement with China's Dalian and Chengdu governments last year to deploy the latest WiMAX broadband wireless technology in these two cities. WiMAX is expected to come soon in China. Antenna for GSM,GSM Antenna,GSM External Antenna,GSM GPS Antenna,GSM GPRS Anetnna,GPS Antenna Yetnorson Antenna Co., Ltd. , https://www.xhlantenna.com
