Wireless Network Adapter PK wireless network adapter

With the development of network technology, our network equipment is becoming more and more complete. Do you have a clear understanding of each hardware in the network equipment? Here we will compare the wireless network card and the wireless network card.

With the advent of the 3G era, wireless network interfaces have become increasingly popular. Wireless Internet access is becoming more and more popular, but wireless network interfaces and wireless network interfaces make it difficult for many people to distinguish. What is the difference between the two? What is the connection between a wireless network card and a wireless network card? We hope that the following articles will help you understand the two.

I heard that when the laptop was able to achieve wireless Internet access at the beginning, someone was holding a mobile phone with an infrared interface next to the notebook, wondering why wireless Internet access is still not available when both the laptop and mobile phone are there. This is a joke, but even today, there are still many people who are not clear about how to connect their laptops to the Internet over wireless.

However, as wireless Internet access technology becomes more and more popular, the "wireless Internet access" era has quietly come to our side. The desire to break through the limitations of Network cables and free Internet access anytime and anywhere has contributed to the growth of the wireless network card market. Now, whether wireless Internet access is available has become one of the main indicators for consumers to determine whether a computer is upscale. But in fact, many people only know about wireless network cards and wireless Internet access cards. Although the two have only one word difference, they are two concepts.

The function and function of a wireless network adapter are the same as that of a common computer network adapter. It is used to connect to a LAN. It is only a device for sending and receiving signals. It can be connected to the Internet only when the egress of the Internet is found. All wireless network adapters must be within the configured range of a wireless LAN. If you want to enable wireless Internet access through wireless wide area networks (WANs) beyond the scope of Wireless LAN coverage, you need to configure a wireless network adapter while having a wireless network adapter. The function and function of the wireless network adapter are equivalent to a wired modem, which is also known as "cat ". It can use the SIM card of a mobile phone to connect to the Internet Anywhere with wireless phone signals. Although both of them can achieve wireless Internet access, their implementation methods and approaches are quite different. Because the mobile phone signal coverage is far greater than the wireless LAN environment, all wireless network interfaces greatly reduce the dependence on the region, which is more convenient for individual users.

Multiple options

Of course, using a mobile phone to enable wireless Internet access is only one way to use a wireless network card. China's wireless WAN includes China Mobile's GPRS and China Unicom's CDMA 1X. Generally, GPRS can only be connected to a laptop. There are three main methods: 1. the GPRS mobile phone can be connected to a laptop through an infrared interface or Bluetooth interface, connect to the Internet through related software. This explains the reason why wireless Internet access cannot be achieved in both laptops and mobile phones. This is entirely because there is no related software support. 2. Connect the mobile phone to the serial port of the laptop through the data cable and use the GPRS mobile phone as the wireless Modem function to access the Internet; 3. Use the GSM/GPRS wireless network adapter through PCMCIA or USB interface, that is, the GPRS Modem communicates with the laptop and connects to the Internet. The last method is easier to use and is favored by consumers. GPRS covers a wide range of areas, so even though the GPRS wireless network adapter has the disadvantages of slow access speed, it is basically the same as the 56Kbps Modem speed, but it can still attract a large number of consumers to buy.

In addition, in March 28 this year, China Unicom launched a business focusing on CDMA 1X wireless Internet access-"zhangzhong broadband", which provides consumers with another option. Mobile Internet access devices provided based on the CDMA 1X business can be inserted with USB interfaces of any desktop computer, laptop, or handheld terminal device, and Internet access can be achieved through the CDMA 1X Wireless Network of China Unicom's new time and space, generally, the transmission speed is 15 K. Because the transmission speed is almost four times that of GPRS, CDMA 1X has a certain advantage in wireless Internet access technology.

However, CDMA 1X wireless network interfaces have been subdivided into many types to meet the needs of different consumers. Now, with Shida Computer Equipment Co., Ltd. (referred to as Shida peripherals), we have released two wireless network adapters that rely on CDMA 1X wireless Internet access technology, that is, the cat family C cat new "wireless STAR" STAR WM-200P and STAR WM-200U as an example, introduce their differences.

"Wireless STAR" STAR WM-200P relies on CDMA 800 MHZ, cdma mhz dual-band support, as long as China Unicom CDMA network coverage, you can enjoy a wide range of reliable, fast, and convenient wireless communication services. Users can achieve fast connection, always online demand through STAR WM-200P. It can also run in OS, MAC, Linux, WINDOWS95/98/2000/XP/NT4.0, PocketPC, and other operating systems. Simple and lightweight. You only need to insert the corresponding PCMCIA Interface of the computer to access the Internet at any time in the CDMA network, send and receive text messages, and perform voice calls. Intelligent Voice call functions make no mistakes in accessing the Internet or making phone calls. All these features of STAR WM-200P bring more convenience to users of laptops.

The difference between the wireless STAR WM-200U and the STAR WM-200P is that it adopts the USB 1.1 plug-in design. This not only meets the needs of the majority of CDMA mobile phone users to achieve Internet access, calls, text messages and other applications on their laptops, but also can achieve the same functionality on the desktop; it supports DOS, MAC, Linux, windows 95/98/2000/XP/NT4.0; PocketPC and other operating systems, the product is lightweight, small, and easy to use. You only need to insert the corresponding USB interface of the computer to access the Internet at any time within the CDMA network, send and receive text messages for voice calls. The unique GPSONE feature with a dedicated antenna can achieve global positioning. The C-cat wireless STAR WM-200U provides broader freedom for mobile voice and data communication.

Free choice of the two platforms

With the support of China Mobile's GPRS and China Unicom's CDMA 1X platforms, a large number of outstanding wireless Nic manufacturers such as Shida peripherals have been created on the market, their products are impacting the selection criteria of Chinese computer consumers at all times-there are different media opinions on the advantages and disadvantages of GPRS and CDMA 1X in terms of technology and performance. As a consumer, how should I select a wireless network card?

Experts give consumers the following comments: based on the difference between GPRS and CDMA 1X in terms of network connection speed and charges, if you are an office user who pays great attention to efficiency, you should select a wireless network card product that supports the stable CDMA 1X platform with fast network connection speed. If you pay more attention to the internet price, then, the 200 RMB monthly subscription (in some places it is already 50-RMB monthly subscription) GPRS will be your best choice.
