Benefits of technology

This solution provides flexible and secure management of network access by dynamically adjusting privileges based on user location and credentials, preventing unauthorized access while allowing authorized users to access appropriate network resources, enhancing security and usability.

Problems solved by technology

In many environments, information on the network is confidential and the ability of unauthorized persons to attach to the network is a serious problem.
Once a wireless client has been located, access is usually denied if the unit is outside the localized area.
This provides security and prevents unauthorized users from attaching or staying attached to the network, but is not very flexible because the system cannot differentiate between authorized users who are properly attached to the network.

Embodiment Construction

[0023]FIG. 1 is a block schematic diagram of a typical wireless network 100. Two wireless clients, 102 and 104, are shown. The wireless clients 102 and 104 are linked to the network 100 by means of access points of which two access points 108 and 112 are illustrated in the figure. Those skilled in the art would understand that at least one access point is required, but typical networks would have many access points.

[0024]The access points 108 and 112 are connected to a network 116 which can be a LAN, such as an Ethernet network, or another type of network. The network 116 may also have other devices, such as servers 118 and 120 connected to it. Network 116 may further be connected to another network, such as a WAN or the Internet via a router 114.

[0025]One or more signal sensors may also be connected to the network 116, of which two sensors, 106 and 110, are shown. These sensors measure the signal strength of the RF signal generated by the wireless clients 102 and 104 and are used b...

Abstract

An access point through which a wireless device attaches to a wireless network determines the access privileges that will be accorded to the device based on a criteria set, such as the ID and physical location of the device requesting network access, the access point through which the device is connected to the network and user credentials. The location of the device is determined by a location determination system using the signal strength of the device signal. The location information and ID information is provided to an access server that uses the criteria set to retrieve access privileges from a privilege database. The retrieved access privileges are then applied to the wireless device by means of the access point and other devices in the wireless network.

Description

FIELD OF THE INVENTION[0001]This invention relates to wireless networks and, more particularly, to controlling access privileges of wireless clients that either attempt to access the network or are connected to the network, but change their status.BACKGROUND OF THE INVENTION[0002]Wireless networks that link together multiple computers are commonplace and the technology for implementing such networks is rapidly growing. The common names for such networking technology are “wireless networking”, “WiFi” or “802.11 networking.” The big advantage of wireless networking is simplicity, because it allows computers to be connected anywhere in a home or office without the need for physical wires, thereby allowing the computers to be mobile. The computers, called “wireless clients”, connect to the network using broadcast radio signals which can travel up to distances of approximately 100 feet.[0003]Wireless networks are generally governed by one of several standards promulgated by the Institute...
