Client devices 12, 14, and 16 represent generally any computing devices capable of communicating with router 10.
Local link 18 interconnects router 10 and client devices 12, 14, 16. Local link 18 represents generally a cable, wireless, or remote link via a telecommunication link, an infrared link, a radio frequency link, or any other connector or system that provides electronic communication between devices 10, 12, 14, and 16. The path followed by link 18 between devices 10, 12, 14, and 16 in the schematic view of FIG. 1 represents the logical communication path between these devices, not necessarily the physical path between the devices. Devices 10, 12, 14, and 16 can be connected at any point and the appropriate communication path established logically between the devices.
Router 10 can be designed to incorporate a data exchanger 20. Data exchanger 20 represents generally any combination of hardware and/or programming that can be utilized by router 10 to connect to a remote network such as the internet. In an embodiment, the data exchanger may take the form of a separate device card that can be inserted into a slot provided by router 10, or otherwise connected to the router 10 through, for example, an I/O port. The data exchanger can be any type of modem that is capable of being received by the router 10 and that can provide the desired connection to the remote network. Examples of suitable data exchangers include cellular data modems, DSL modems or cable modems.
A service provider 22 represents generally any infrastructure configured to provide internet related data services to subscribers such as an owner of data exchanger 20. For example, where data exchanger 20 is a cellular modem, service provider 22 may be a cellular telephone service provider capable of providing voice and data services to subscribers allowing access to internet 26. Where data exchanger 20 is a DSL or cable modem, service provider 22 may be a more traditional internet service provider (ISP) providing data access to internet 26 through wired means.
A remote link 24 interconnects data exchanger 20 and service provider 22 and represents generally any combination of a cable, wireless, or remote connection via a telecommunication link, an infrared link, a radio frequency link, or any other connector or system that provides electronic communication between data exchanger 20 and service provider 22. Remote link 24 may represent an intranet, an internet, or a combination of both.
FIG. 2 is a block diagram illustrating exemplary physical and logical components of router 10. As described above, router 10 represents generally any combination of hardware and/or programming capable functioning as a router for directing network communications between client devices on the local network, or between client devices and the internet via data exchanger 20.
In the example of FIG. 2, router 10 includes local network interface 30 and data exchanger interface 32. Local network interface 30 represents generally any combination of hardware and/or program instructions capable of supplying a communication interface between router 10 and client devices 12, 14, and 16 shown in FIG. 1. Data exchanger interface 32 represents any combination of hardware and/or programming enabling data to be communicated between router 10 and a data exchanger 20 shown in FIG. 1. For example, interface 30 may include a transceiver operable to exchange network communications utilizing a wireless protocol such as ultrawideband (UWB), Bluetooth, or 802.11. Other examples of interfaces 30 and 32 include physical ports or other physical connection points enabling wired communication, such as USB ports, Ethernet ports, and Firewire ports. The data exchanger interface 32 could also be, for example, a slot for a device card, such as PCMCIA or ExpressCard, as will be discussed in greater detail below.
Router 10 also includes routing services 36 and web server 38. Routing services 36 represent generally any combination of hardware and/or programming for routing network communication received through local network interface 30 to be transmitted by data exchanger 20 to internet 26. Routing services 36 is also responsible for routing inbound network communications received from internet 26 and directed via local network interface 30 to a specified client device 12, 14, or 16. Outbound and inbound network communications, for example can be IP (internet protocol) packets directed to a target on internet 26 or to a particular network device 12, 14, or 16 on a local area network.
Web server 38 represents generally any combination of hardware and/or programming capable of serving interfaces such as web pages to client devices 12, 14, and 16. Such web pages may include web pages that when displayed by a network device allows a user to provide or otherwise select settings related to the operation of router 10.
Router 10 can optionally include a connector 34. Connector 34 represents generally any combination of hardware and/or programming for sending a signal to data exchanger 20 to establish a data connection with service provider 22 so that access can be made to internet 26. For example, where a data exchanger 20 is a cellular modem, connector 34 may send a signal causing the cellular modem to establish such a data link with service provider 22. In an embodiment, the router does not include a connector 34. In an embodiment, the hardware and/or programming for establishing a data connection with service provider 22 is included in the cellular modem.
The router 10 can optionally include a limiter 40. Limiter 40 represents generally any combination of hardware and/or programming capable of distinguishing among the users of devices such as client devices 12, 14, and 16, and applying different internet access rules for different users. For example, certain internet access rules may apply to the owner of router 10. In this context, the term owner refers to an individual or entity that is a subscriber with respect to a service provider such as service provider 22 shown in FIG. 1. The owner typically has physical possession or otherwise has control of router 10. Other internet access rules can apply to users authorized by the owner. Yet other internet access rules apply to anonymous users. Where local network interface 30 provides for a wireless connection with client devices, a user of a particular client device might not be known by the owner. As such, internet access rules for such users may be quite limiting. The limiter 40 and operation thereof is discussed in greater detail in U.S. patent application Ser. No. 11/673,956, filed Feb. 12, 2007, in the name of Pat Sewall et al., the disclosure of which is hereby incorporated by reference in its entirety. In an alternative embodiment, router 10 does not include a limiter 40.
In an embodiment, router 10 may be located in a publicly accessible area. For example, router 10 may be securely mounted to a wall or other location, to prevent unauthorized people from removing the router from its designated location. As described previously, the data exchanger 20 may take the form of a separate device card that can be inserted into a slot provided by router 10, or otherwise connected to the router 10 through an I/O port. One such example is illustrated in FIG. 3A, where the data exchanger 20 is inserted into a slot 21 located in router 10. While the router 10 may be securely attached to a certain location, the data exchanger 20 is in an unprotected state, allowing unauthorized persons to tamper with, damage or steal the data exchanger 20.
To discourage or prevent these unauthorized actions, a security enclosure 11 (FIG. 3B) is designed to mate securely to router 10. When attached to router 10, the security enclosure 11 covers the data exchanger 20, preventing unauthorized persons from accessing the data exchanger 20. Security enclosure 11 can be attached to the router in any suitable manner. For example, security enclosure 11 may snap fit or overlap with a portion of the router 10, as shown in FIG. 5. Additional or alternative attachment features may include, for example, a flange and screw system 140 shown in FIG. 3C to affix the security enclosure 11 to the router 10, while also providing protection from tampering. Any other suitable attaching means could also be employed in place of those listed above.
In an embodiment, the security enclosure 11 may incorporate additional attributes that improve the utility of the router 10 or data exchanger 20. For example, as shown in FIG. 4, the security enclosure 11 may include a battery 142 that attaches electrically to the router 10. If desired, the battery 142 can be charged by the router 10 when the router 10 is connected to wired electrical power. The battery 142 provides power to the router 10 if the wired electrical power fails.
In an embodiment, the security enclosure 11 may include an antenna 144 which is attached to the data exchanger 20 to improve the signal reception and transmission of the data exchanger 20. Alternatively, the antenna 144 may attach to the router 10 to improve the signal reception and transmission of the router 10 when communicating wirelessly with, for example, local client devices 12, 14, and 16.
Cables may be used to connect antenna 144 to the router 10, or connect the antenna 144 to the data exchanger 20. Cables may also be used to connect the battery 142 to the router 10.
In an embodiment, the security enclosure 11 may contain the data exchanger 20 that is embedded in or otherwise attached to the security enclosure 11. In this configuration, the person assembling the security enclosure 11 to the router 10 may use a cable (not shown) to create the electrical connection between the data exchanger 20 and the router 10, prior to attaching the security enclosure 11 to the router 10.
Alternatively, the electrical connection between the router 10 and the antenna 144, or the electrical connections between the router 10 and the battery 142, or the electrical connections between the router 10 and the data exchanger 20 embedded in the security enclosure 11, may be designed such that the connections are made automatically when the security enclosure 11 is attached to the router 10. The connections can be made in any suitable manner. In an embodiment, these connections may be made through traditional electrical connectors, with one set of connectors attached to the security enclosure 11 and a mating set of connectors attached to the router 10, where the connectors are positioned so as to make physical connection as the security enclosure 11 is physically attached to the router 10. For example, as shown in FIG. 6, when security enclosure 11 is attached to router 10, a connector 146A mates with connector 148A, a connector 146B mates with connector 148B, and a connector 146C mates with connector 148C. Any number or type of connections can be employed in place of or in addition to those shown in FIG. 6.
