Inexpensive Radius Server Gives Wireless Networks The Security They Need

Many small businesses have planned to connect computers and other devices to the corporate network via wireless (WLAN) connections, and a little courage did. Many of these principles requires that the network of wireless devices to be carefully placed inside the building, so that the wireless has reached all recipients. Normally, these networks have sufficient safety devices, such information vulnerable and theft of resources by unauthorized persons. These two problems are largely solved, meaning that they can be more time for small businesses to explore the potential benefits of a wireless network can offer. Wireless networks basic construct a wireless network requires two types of hardware components, wireless access points and wireless cards. The wireless access point is a device connected to computer networks through a standard Ethernet cable. It has an antenna on this subject, so that sending and receiving signals from computers and other devices. Each entity that wishes to communicate with the access point will need a map wireless access, which also contains an antenna. This wireless standard known as 802.11n, up to 54 megabits per second of data that are transmitted between access points and access to the card. Although not as fast as kabelnett, which usually operates in 100 megabits to 1000 megabits per second, wireless networks, provide greater flexibility, May and be less expensive to install. This is particularly true for older buildings where installing cable can be cost prohibitive. Cutting Corners wireless network uses radio waves to transmit information and, therefore, is likely to be blocked by walls and other obstacles in a building. These obstacles can lead to dead zones in which radio waves are not able to achieve its objectives. The microwave ovens and other radio frequency devices can also wreak havoc on wireless signals. The solution is to place wireless access points strategically around the building to minimize interference. When the distance between a wireless access point for wireless device is more than a few tens of meters, wireless repeater can be installed in order to strengthen the signal. These repeaters can be installed so that wireless signals May be available in every corner of the building. Wireless Network Security Solution Install a simple wireless network is easy, but to install a wireless network may be considerably more difficult. But Ann Arbor company Interlink Networks is now offering its LucidLink products, making full installation of the security of wireless networks at a glance. Before LucidLink available, an organization that wants to terminate their wireless network would have to hire expensive consultants network security to install and manage the wireless network. LucidLink all packages on this experience in a software add-on that are so easy to use that even a small business office manager can easily take control over who has access to society through the wireless network. It goes beyond the sole authentication (standard with most wireless routers), and manages what is known as a RADIUS server. RADIUS servers, it is large organizations thousands of dollars for the installation and maintenance to ensure its wide (1000 + node) wireless network. Until now install a RADIUS server is out of the price range for all larger companies. However, LucidLink product can be purchased for as little as $ 99 per user 3 Home Office Edition, $ 449 for a version 10 users, and goes up to $ 3995 for a version of the 250 users. Abstract Although there are still problems to ensure that all parts of a building is covered, the current standard Wi-Fi (802.11g) has a more powerful signal, less emphasis should be placed in places connected devices. But it is always recommended that a professional site survey was conducted to confirm that all requirements in certain parts of the building can be reached by the wireless signal. In the meantime, Interlink Networks has finally solved the problem of security at a price that is affordable for small and medium enterprises. Terrence A.
