How To Shop For Wireless Notebook Computers
All communications and data transfer devices, whether laptops or phones, are going wireless these days. There are different types of wireless connection setups that we can use one for own needs. These setups include Wi-Fi, 3G EV-DO, Bluetooth module, etc. Among the three, Wi-Fi (Wireless Fidelity) is the base of the most important part of our life- wireless notebook computers.
Wireless connection is not a breaking news nowadays. They have already influenced our day to day life and have converted many of our wired setups such as Internet access and data transfer in to wireless ones. But such a revolution did not come in one day. Development of wireless technology started in the field of communication. Cell phones were the first devices to use wireless technology for data transfer purposes. From there, technology was borrowed and integrated into notebooks to produce wireless notebooks.
Wireless notebooks provide data transfer and communication channels through a wireless card integrated into the hardware configuration of a notebook computer.
Notebook computers accomplish the task of wireless communication and data transfer by using three major standards: 802.11 b standard, 802.11 a standard and 802.11 g standard. Out of these three the 802.11 b is the most basic one while 802.11 g is the most advance one. Many of us are familiar with the 802.11 b standard. We call it Wi-Fi in our every day language. It is capable of exhibiting a data transfer rate of 11 Mbps. It works on the 2.4 GHz radio spectrum. Though the eventual rate is not more than 5-6 Mbps, it is enough for gaming and internet surfing. The 802.11 a standard works over the 5 GHz spectrum and gives data transfer rate of 54 Mbps. This standard provides 8 channels that help achieve faster data transfer rates. 802.11 g is the most advance standard. It is a hybrid variety that is made up of the a and b standards. The next technology these wireless network connections make use of is the 3G Evolution Data Optimization technology. This technology helps to download at a speed of 400 to 700 kbps. A notebook computer can also be made wireless with the help of a router and a wireless network adaptor card. Some notebook computers come with blue tooth technology that enables wireless communication between any types of devices (whether cellular phones, stereos or headphones). Interruption of the radio frequency on which data transfer takes place is something that has emerged as a new threat. With the right type of equipment and a little use of brains, a person can hack into the flow of data. To prevent such intrusions and interruptions, certain address filtering methods have been developed. These are the Media Access Control (MAC) and Wireless Encryption Protocol (WEP) address filtering methods. Using these methods, wireless notebook computers can become a safe site for critical data transfer and communication.
