How wireless communications made by the portable PC or notebook you ask? Portable wireless uses three major standards for wireless data transfer data. It is probably most common is 802.11b, also known as Wi-Fi as a means Wireless Fidelity. Wi-Fi 802.11b transmits data wirelessly to a maximum speed of 11 Mbps for a maximum of 150 feet. It uses the 2.4 GHz radio spectrum, and even if it is 11 Mbps, it will probably reach only about 4-6Mbps in actual use. But this is enough bandwidth for high-speed Internet access, games and most file transfers. The 802.11a is a different standard that uses the 5 GHz spectrum, it has 8 channels available instead of only 3 is available with 802.11b.

The second standard, 802.11g, is a hybrid of A and B - also its ability to 54Mbps, but uses the 2.4 GHz spectrum and is compatible with 802.11b devices. Some portable Fujitsu LIFEBOOK N6010, is a tri-mode 802.11a/b/g wireless system that uses three ways! The next wireless communication technology 3G EV-DO! Sounds like a robot StarWars pleasure - but it is for developing data optimized. This new technology will change the way you see and use the World Wide Web.

MAC (Media Access Control) address is physical or material unique identifier for each device on the network. Then, manually enter a list of addresses you can use or access your wireless network. The second screening process is safer, WEP or Wireless Encryption Protocol requires a key that is shared among users, and then use that key to encrypt and encode data transfer between users of their networks. Most major hotel chains and other companies already offer Wi-Fi services such as greater convenience for their customers. These hotspots are popping up everywhere, even in some stations. You May to register or obtain a password or key access to these services. But, as his mobile telephone conversations, any wire or radio transmission will not be as safe as a cable connection.
