Analysis of WiFi Antenna

Introduction of WiFi and WiFi Antenna

WiFi is widely used in our daily life, because the rapid development of wireless networks at present, antenna and its applications are getting better and better. WiFi make use of a short-range wireless transmission technology. When you come to a coffee shop, or even a restaurant, you can also find the WIFI logo. The wifi antenna are often used in these places. The WiFi antenna has different shapes, sizes and materials, and the specific process of the WiFi antenna. Compare the performance of WiFi antenna with the antenna system. The computer does not have an internal wireless network to connect to a wireless network, when we need to use an external antenna. Without this antenna, computer users cannot connect his own computer to the modem to access the Internet by using a network cable. If your computer does not have built-in WiFi antenna, then you must install an external WiFi antenna to your computer.


The Advantages of WIFI Panel Antenna

There are many various kinds of WiFi antenna in the market. A wifi panel antenna is a parabolic reflector, the parabolic cross-sectional shape of the curved surface, in order to direct the radio wave, antenna is established. The most common type of shaped like a dish is commonly known as a dish antenna or parabolic. The main advantage of the panel antenna is that it has a high directivity, the narrowest beam width. These provide some of the highest gains, and they may be generated. There must be much larger than the wavelength of the radio waves being used in order to obtain a narrower beam width, panel reflector, so the use of the radio spectrum in the panel antenna is frequent portion in the UHF and microwave. As a panel antenna, high-gain antenna has the point-to-point communications, in the application, such as a microwave relay link, telephone and television signals, wireless WAN / LAN connections for data communications, satellite communications and spacecraft communications antenna near the cities. They can also be used in the radio telescope.

Other Usages of WiFi Antenna

With the development of home satellite television channels, panel antenna has become a common feature in the landscape of the modern state. The extensive use WiFi antenna becomes also more and more popular, where there is a need to transmit radio waves in to the extremely narrow beam positioning objects, such as ships, aircraft and missiles.

WiFi antenna and application

Simply put, WiFi is connected to each other. At home, WiFi can make cell phones, computers, share-players , and other devices share and do not need any cables. Whether in the Office, airport or coffee shop, you can work through a WiFi connection to the Internet anywhere, anytime, even when you're far away from home. Now you can imagine everything is simple and convenient, then you don't have to worry for the cable network. This is the WiFi.

How WiFi works?

Wifi network applied 802.11 wireless technology can provide safe, reliable, fast wireless connection. WiFi networks can be used in electronic equipment and electronic devices, the Internet and cable network connection using Ethernet technology.WiFi works in bands of 2.4G and 5.8G. Some WiFi devices can work in dual band.We  could experience similarly with cable network.

Is wifi tailored for me?

The enterprice-class IT and wifi certificated products used in corporation and schools extend wired network to public areas, like conference rooms, training rooms and a large auditorium. Many companies provide wireless network for outdoor and far away worked employees at home or romote office.Big companies and schools often use wifi for connection between blocks.

Smaller companies also use WiFi networks, for communications between mobile sales people, behind fixed office workers, investors, and financial officers.
Home offices have benefited from wifi technology. Working at home is very confortable.You just need a simple access point to connect computers, printer, scanner, smartphone, audio device and other wireless devices. So there is no cable of different sort under desk.

Today wifi products can apply in many ways, from sending messages to transmit video and Conference calls.  Even wireless network connections outside the 100-foot, of course, connected distance is reduced because the Hall block. WiFi products of different shapes, to meet all of your needs, some of them very cheap.

 WiFi popularity is the result of numerous companies, technologists and engineers working together. In mid 90, experts from many companies gathered together throug the League of Nations IEEE, to achieve new industry standards of new wireless products connected. WiFi Alliance was born from this collaboration, have such standards development/testing laboratories in the world, to test if reaching product availability and security standards .

WiFi products through radio waves, just like mobile phones, automatic door, TV, radio, GPS, and a microwave oven.

Each of these products have its frequency band.
Examples of wireless bandwidth
AM broadcasting (530-1610 kHz)
Short-wave frequency band (5.9-26.1 MHz)
Private band (26.965-27.405 MHz)
TV channel 2-6 (54-88 MHz)
FM broadcast band (88-108 MHz)

Wi-Fi products work in 2.4GHZ or 5GHZ band. These bands do not need government authorization, individuals are free to use, like television and radio must use the authorized band. Free charge of wifi frequency, guarantee the availability of products through the WiFi Alliance standards ,which is even more important for manufacturers. Because these products and non-WiFi product shared frequency bands, such as remote controlled toys, certification testing can ensure the WiFi products do not interfere with other products, other products also will not be interference.

Availability

Availability means that products of different companies can work together, so users will not be restricted to a brand of WiFi products. More than 400 WiFi Alliance member company products will be WiFi certified, which means that you have a lot of products to choose from, without worrying about product compatibility problems.

What is 802.11?

Today WiFi products are specified by Dewey Decimal-like, the system developed by IEEE to differentiate the various technology clusters. Labelled 802.11 WiFi products embodiment and identity in the future more detailed specific implementation technologies, such as 802.11A. Each identified labelled assembly is defined by performance, frequency and bandwidth. Each generation of technology will enhance safety performance, will also include other features, of course, manufacturers can be selected according to the actual situation.

Now there  are 4 WiFi products, more and more are using standard is adding new features, improved performance and security. Each generation is defined by a series of performance parameters, including performance, frequency and bandwidth. Each generation of technology will enhance safety performance, will also include other features, of course, manufacturers can select according to the actual situation

WiFi certification test is to ensure that the product can compatible with the previous generation of WiFi products operating on the same frequency.

     So, for example, through WiFi certification product indicates that the product is not only 802.11g but also WiFi 802.11b or 802.11n products (2.4GHz) working together.

     This means that you can use the new device access existing WiFi network and don't have to worry about compatibility issues. Wifi-certified products will put a logo on identification to indicate that the product meets all the identifying comments on standards.

     Asian Creation Communication antenna factory  are committed to exploring the application of the WIFI/WLAN antenna in the wireless local area network, and strive to make our existing WIFI base station antennas (including flat-panel antenna, sector antenna,CPE antenna, parabolic antenna,grid antenna, Omni fiberglass antenna, Yagi antenna etc high-gain outdoor antenna), WIFI antenna of the wireless devices (including the simple installation of the terminal antenna, mobile antenna, indoor ceiling antenna, indoor wall antenna etc) signal reception in a wireless communication network with the launch of higher sensitivity and stronger.
