Multiuser WiFi bandwidth allocation method and apparatus
A method for controlling data throughput of a public user at a subscriber access point, including determining if the public user has established a connection at the subscriber access point, measuring the physical layer data rate of the public user retrieving a maximum channel usage time limit and limiting an amount of data transferred on a per unit of time basis responsive to the measured physical data rate and the maximum channel usage time limit.
1. A method for limiting an amount of data transferred at a subscriber access point, said method comprising:
determining if a connection has been established with said subscriber access point;
measuring a physical layer data rate of said connection;
retrieving a maximum data rate usage time limit from a storage, said maximum data rate usage time limit being based on at least averages of physical layer data rates; and
allocating a data rate per unit of time based on said measured physical layer data rate and said maximum data rate usage time limit by reducing a bandwidth for connections having a physical layer data rate below a level.
2. The method according to claim 1 , further comprising determining if there are additional public users which have established connections with said subscriber access point or if an already connected public user's physical layer data rate has changed.
3. The method according to claim 2 , wherein said steps of measuring, retrieving and allocating are repeated if there are additional public users which have established connections with said subscriber access point or if an already connected public user's physical layer data rate has changed.
4. The method according to claim 1 , wherein said subscriber's access point is a private access point.
5. The method according to claim 4 , wherein said private subscriber's access point behaves as a public hotspot.
6. A subscriber access point for limiting an amount of data transferred at said subscriber access point, comprising:
a bi-directional user interface for establishing a connection;
a module to measure a physical layer data rate of said connection, said module to measure a physical layer data rate of said connection in bi-directional communication with said bi-directional user interface;
a storage system including a maximum data rate usage time limit, said maximum data rate usage time limit being based on at least averages of physical layer data rates; and
a module to allocate a data rate per unit of time, said module to allocate the data rate per unit of time in bi-directional communication with said module to measure said physical layer data rate of said connection and also in bi-directional communication with said storage system, said module to allocate said amount of said data rate per unit of time allocating a data rate per unit of time based on said measured physical layer data rate and said maximum data rate usage time limit by reducing a bandwidth for connections having a physical layer data rate below a level.
7. The subscriber access point according to claim 6 further comprising a service provider interface for updating said maximum data usage time limit.
8. The subscriber access point according to claim 6 , wherein said subscriber access point is a private access point.
9. The subscriber access point according to claim 8 , wherein said private subscriber access point behaves as a public hotspot.
