`WIRELESS NETWORK HAVING MULTIPLE
`COMMUNICATION ALLOWANCES
`
`This application claims priority to US. Provisional Ser.
`No. 60/454,694 ?led Mar. 14, 2003.
`
`FIELD OF INVENTION
`
`Wireless networks are well-known, and may be based, for
`example, on the 802.1 1 standard. Because the contents of the
`wireless network can be received by anyone with wireless
`access, security may be achieved through encryption of the
`stream. Anyone with an encryption code can tap into the
`network. Those without the encryption code, however, simply
`cannot decode the wireless stream. In addition, standard net
`work protocols may be used, so that not only the encryption
`code, but also a network login, is necessary.
`
`SUMMARY
`
`The present application describes a wireless network,
`de?ning a plurality of different classes of service, where the
`different classes of service include at least a ?rst class of
`service that includes a ?rst set of permissions for access to
`resources, and a second class of service which includes a
`second set of permissions of access to resources.

`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`These and other aspects will now be described in detail
`with reference to the accompanying drawings, in which:
`FIG. 1 shows a basic diagram of the networks described
`herein.
`
`30
`
`DETAILED DESCRIPTION
`
`Wireless networks have been used for other things besides
`secure ?le transfer. For example, Internet Cafes, and “wire
`less hot spots” may include the capability of communication
`to a user’s personal laptop which is equipped with a wireless
`card. This may use a network key for the encryption of the
`word “public”, or a network key which is given to users who
`pay for the service or pay for a drink or food, or without any
`network key at all. Certain areas such as hotel rooms are often
`wireless enabled. However, the communication is typically or
`totally on, or totally off; that is either the user is allowed to
`receive wireless Internet, or the user is blocked from all
`communications.
`The present system teaches a network with multiple levels
`of capability, depending on the access credentials possessed
`by the user. FIG. 1 shows this being carried out using multiple
`network cards or NICs. However, the same effect can be
`obtained with a single NIC. Preferably the network cards are
`wireless, using one of the features of IEEE 802.11 wireless
`communication protocols.
`Different classes of users may be assigned. The ?rst class
`of users, shown as user 1, are allowed ?le access to ?les and
`information from the server. These users may be given the
`encryption key, here for the ?rst NIC 100 here shown as
`ABCDEF. These users may be allowed the highest level of
`access to resources. As conventional users who have the com
`plete set of credentials, they are allowed unlimited upload and
`download, and full ?le access (that is allowed to non-admin
`istrator users). In addition, these users may be allowed the
`maximum upload and download speeds which is given to
`network users, and to receive all different kinds of Internet
`and ?les from all sources.
`For example, the amount of access which is provided to
`these users may be assigned by the operating system which
`
`35
`
`40
`
`50
`
`55
`
`65
`
`2
`drives the NICS. For example, if Windows XP is used as the
`operating system, it may assign NIC 100 with unlimited ?le
`access.
`A second class of users shown as user 2 do not have the
`credentials, here the encryption key, for the network card 100,
`and hence use the encryption key “public” and thereby can
`only communicate with the network card No. 2 shown as 110.
`Alternatively, these same users may communicate using no
`encryption key at all. The network card 110 allows only some
`subset of the operations that are allowed by the network card
`1 00. For example, the user 2 may receive Internet only, and no
`?le access. They may be allowed to print. In addition, the
`upload and download speeds may be limited or severely lim
`ited; for example, the Internet may be limited to 1M download
`speeds and 100K of upload speed.
`This system as described above may be usable in an o?ice
`environment. For example, users who are actually members
`of the of?ce obtain ?le access, while visitors only receive
`print and Internet access.
`Another contemplated use is in pay-for-Internet use. The
`user 1 may pay a higher fee than the user 2. For example, user
`2 may pay only for limited Internet, while user 1 may pay for
`access to resources such as video over IP, and higher down
`load speeds from the Internet.
`In addition, a third class of users shown as user 3 may be
`de?ned. These users communicate only to NIC 120. Note that
`while this describes users 1, 2 and 3, any subset of these users
`may be used, for example a system may be con?gured which
`only communicates with user 1 and user 3. The NIC No. 3 is
`shown as having no encryption code whatsoever. User 3 is
`limited even further. User 3 may receive only commercial
`parts of the Internet. In the of?ce environment, this may limit
`the Internet to web pages describing the of?ce and/ or certain
`intranet sites. In a pay for internet environment, this may
`describe the “free” user, who may only receive certain con
`tent. User 3 may also receive a severely restricted bandwidth
`and/or only a limited quantity of information. For example,
`the user 3 may be assigned a token which allows them only to
`receive for example total of 1 megabytes of download and
`only to upload 100 Kilobytes of upload. This even further
`limits the user 3.
`As described above, the different users in their different
`classes have different levels of ?le access, and resource
`access, resource speed and resource amount.
`FIG. 1 shows this being carried out with three different
`network cards over the same airspace. Alternatively, the three
`different networks may be carried out as part of a single
`network card; shown as network card 130. For example, this
`may include three network resources which operate on the
`single card. Alternatively, the three different kinds of
`resources may be carried out in software, for example this
`may be carried out by three different network resource allow
`ances within the software that runs the network card or within
`the server 99.
