Abstract

The method comprising at least one Access Point (AP) with a single half duplex radio transceiver allowing the transmission from said AP to a plurality of associated stations connected to any of said two wireless networks, said two wireless networks operating at different frequency channels. Embodiments of the method in order to create said two wireless networks comprises said at least one AP updating a plurality of beacon parameters from a beacon frame at each change of channel frequency of said half duplex radio transceiver.

The system of the invention is adapted to implement the method of the invention.

Claims

1. A method for creating two independent wireless networks with an access point, a first wireless network operating at a frequency channel A and a second wireless network operating at a frequency channel B, comprising:

at least one access point (AP) with a single half duplex radio transceiver changing the frequency channel between said frequency channel A and said frequency channel B in alternate periods of time;

a plurality of associated stations operating in said frequency channel A; and

a plurality of associated stations operating in said frequency channel B,

characterized in that, in order to create said two independent wireless networks from said at least one AP, it comprises updating a plurality of beacon parameters from a beacon frame at each change of channel frequency of said single half duplex radio transceiver.

2. A method according to claim 1, characterized in that it further comprises:

pre-configuring said plurality of beacon parameters of said beacon frame for the two wireless networks with a corresponding Basic Service Set Identifier (BBSID) parameter, one BBSID parameter corresponding to said first wireless network and another BBSID parameter corresponding to said second wireless network, and

transmitting, from said at least one AP, data packets corresponding to said two wireless networks in two different queues, a first queue corresponding to said first wireless network and a second queue corresponding to said second wireless network.

3. A method according to claim 2, characterized in that it comprises transmitting and/or receiving said data packets from said at least one AP only during a corresponding operation time period.

4. A method according to claim 1, characterized in that said plurality of beacon parameters updating comprises modifying from said beacon frame the field parameters:

SSID parameters, DS parameters and HT info.

5. A method according to claim 4, characterized in that it comprises updating from said SSID parameters a SSID string field and a tag length field.

6. A method according to claim 4, characterized in that it comprises updating from said DS parameters a channel number field.

7. A method according to claim 4, characterized in that it comprises updating from said HT info field a Primary channel field and a HT info subset 1 field.

8. A method according to claim 1, characterized in that it comprises assigning to each one of said two wireless networks a same or a different Service Set Identifier (SSID).

9. A method according to claim 8, characterized in that it comprises further assigning to each one of said two wireless networks a different frequency and different operation time intervals.

10. A method according to claim 1, characterized in that it performs a dynamic channel selection by means of a channel scanning process in order to determine said channel frequency that better supports wireless operations.

11. A method according to claim 1, characterized in that it comprises prioritizing said two wireless networks transmissions depending on a plurality of wireless services requirements.

12. A method according to claim 11, characterized in that it comprises performing said prioritizing said two wireless networks transmission by assigning different channel frequencies and/or assigning different operation time intervals to said two wireless networks.

13. A system for creating two independent wireless networks with an access point, a first wireless network adapted to operate at a frequency channel A and a second wireless network adapted to operate at a frequency channel B, comprising:

at least one Access Point (AP) with a single half duplex radio transceiver and adapted to change the frequency channel between said frequency channel A and said frequency channel B in alternate periods of time;

a plurality of associated stations adapted to operate in said frequency channel A; and

a plurality of associated stations adapted to operate in said frequency channel B,

characterized in that, in order to create said two independent wireless networks from said at least one AP, it comprises updating a plurality of beacon parameters from a beacon frame at each change of channel frequency of said single half duplex radio transceiver.

14. A system according to claim 13, characterized in that it is adapted to implement a method for creating the two independent wireless networks with an access point, the first wireless network operating at a frequency channel A and the second wireless network operating at a frequency channel B, comprising:

wherein, in order to create said two independent wireless networks from said at least one AP, the method comprises updating a plurality of beacon parameters from a beacon frame at each change of channel frequency of said single half duplex radio transceiver.
