can not meet the growing business needs, so IEEE in 1999 has launched a 802.11b, 802.11a two standards. And at the end of 2001 through the 802.11G Trial hybrid scheme, which can achieve 54Mbps data rates in the 2.4GHz band, and compatible with the 802.11B standard.
802.11b work in 2.4GHz ISM (industrial, technical, medical) band, using direct series spread spectrum and complement keying, can support 5.5Mbps and 11Mbps two kinds of speed, can with the rate of 1Mbps and 2Mbps 802.11 DSSS (direct

Hardware firewils don't have to be expensive. For instance, Netgear and Linksys models sport sufficient features for a reasonable cost.
Hardware firewalls are not expensive. For example, the Netgear and Linksys modules are worth the money.Endurer Note: 1.
Ruckus Wireless, Inc. (Ruckus), the developer of the next-generation Wi-Fi Wireless local area network product, has released a new product and technology that revolutionizes the distribution of multimedia content in the home. The products launched by Ruckus Wireless include the industry's first multimedia Wireless Routing System "Ruckus MF2900" and multimedia adapter "Ruckus MF2501", all of which are officially listed.
