The development of human thinking generate technology development in all fields. No exception in the field of information technology. Some kinds of the latest technology, it offered to replace the old technology or simply to increase options for users.
Cable as the only media to the occurrence of a local connection finally get a competitor with the emergence of wireless technology (Wi-Fi). By offering the ease of installation and configuration, and not the limited space (with certain restrictions), plus the convenience of care, eventually make a lot of people move to this technology.
Then the problem becomes a security issue that interesting. Various new technologies in the field of wireless security is created. Start from the NAT firewall, encryption (WEP, WEP2, WPA, etc) to the MAC Address filtering, increase the popularity of wireless technology (Wi-Fi). This is better dealt with by some vendors to wireless devices to create a Wireless Router, A wireless router is a network device that performs
the functions of a router but also includes the functions of a wireless access point. It is commonly used to allow access to the Internet or a computer network without the need for a cabled connection. It can function in a wired LAN (local area network), a wireless only LAN, or a mixed wired/wireless network. Some vendors even add some features such as VPN, VOIP, Anti-Virus, Anti-Spam, Anti-Malware, Anti-adware, etc. See Netgear with Netgear WGT624SC Super G Wireless Router product, SpamCube, and Eli Security with TrustEli Security Appliance .
The latest technology in the Belkin N1 Wireless Router from Belkin, Buffalo Technology’s AirStation Nfiniti from Buffalo Technology, D-Link’s RangeBooster N from D-Link, the Linksys Wireless-N from Linksys and Netgear’s RangeMax Next from Netgear; increasingly selling wireless router . By using the 802.11n standard, with access speed up to 150Mbps and a significant increase troughput, are already not need to happen again delay access, which is often experienced by users Wi-Fi (802.11b standard).
In the end we can determine which technology will be applied. And as one of the reference materials, we can see at wireless router wiki.
