Wireless network technology in the continuous development and improvement, and wireless technology is a complement not a substitute to compare with cable network.
Home networking is the choice for wireless access or wired access, choice may seem difficult, in fact, it is very simple. The user according to their own needs, and then choose a suitable network access. Up of general words, the pursuit of cost-effective network cabling and no need to consider the impact of the layout of home users the choice of cable network. If the user want to use the network more flexible, so that they can choose the wireless network. Both of the network ways have its own advantages, so that we can not say which one is better than another one.
In this paragraph the author will look at the wireless technology to relevant with mobile phones, that includes 1G and 3G; Infrared; Bluetooth; Wifi; and WiMax.
- 1G, can only make voice call.
- 2G, based on the 1G functions, 2G has increased the function of receiving data, such as receiving e-mail or Web page
- 3G, it is 3rd generation has high-speed that supports video and other rich media, always-on transmission for e-mail, web browsing, instant messaging. Third-generation mobile phone has a large color screen, and most of them are touch-screen. 3G mobile phone users can directly write on the touch screen, drawing, and send it to another phone, and the time required may be less than one second. Of course, you can also transfer this information to a computer, or download some information from the computer;3G mobile users can directly use the Internet, check email or browse the Web; There will be many models of 3G mobile phone comes with the camera, which will allow users to use their phones to have face to face meeting with their friends.
- Infrared, Can make use of infrared and desktop computers and other related equipment to exchange information. Mobile infrared can integrate mobile phone with a computer or other wireless connection, the premise is both the connector has the infrared. If the user want to transmission photos to the computer, then close to the computer infrared port, the computer automatically signal search is successful will appear in the computer system.
- Bluetooth, is actually a short distance wireless technology, the use of "Bluetooth" technology, which can effectively simplify the Pocket PC, laptop and mobile phone handsets and other mobile communication terminal for communication between devices, but also more successful in simplifying the equipment and Internet communication between these modern communication devices so that data transmission between the Internet more quickly and efficiently.
- WiFi, its biggest advantage is the high transmission speed, up to 54Mbps, while its effective range is also very long. Its application can be on the LAN AP Internet access, you can also make VOIP ( Voice over Internet Protocol ) calls, but China does not have the WiFI VOIP operators, so WiFI phone is listed in China are not allowed.
- WiMax, WiMAX is an new wireless communication technology, can provide for high-speed Internet connection that provide the technology allegedly covered by thirty miles wide high-speed Internet connection.
All the technologies have mentioned above are very useful and make human beings life more and more convenient. However, in the author's opinion, if a cell phone have wifi and bluetooth and also wimax function at the same time, and operating them at the same time, will there be any conflict between each other?
