Abstract

Systems, devices, and methods relate to a hybrid wireless access point (AP) which can support both single-channel mode and multi-channel mode at same time and within the same device. Uplink and/or downlink packets may be received by the hybrid AP, where the received packet may be same packet sent to different hybrid APs, and then each hybrid AP may decide to use these received packets for single-channel architecture (SCA), multi-channel architecture (MCA), or both. In SCA, the hybrid APs may communicate with each other to sync the SCA behavior.

First claim

What is claimed is:

1. A system comprising:
a switch;
one or more portal access points (APs), wherein each portal AP of the one or more portal APs is connected to the switch by a wired connection; and
one or more satellite APs, wherein each satellite AP of the one or more satellite APs is configured to utilize one or more wireless paths to a portal AP of the one or more portal APs by a wireless connection;
wherein each portal AP and each satellite AP is configured to utilize a channel blanket (CB) as part of a single channel architecture, such that each portal AP employs a same channel and a same basic service set (BSS) media access control (MAC) address, and each satellite AP employs a same channel and a same basic service set (BSS) media access control (MAC) address;
wherein when one or more synchronization frames are transmitted between the one or more portal APs and the one more satellite APs, the one or more portal APs are configured to receive the one or more synchronization frames via at least one of: a wired LAN and a wireless LAN, and the one or more satellite APs are configured to receive the one or more synchronization frames via the wireless LAN;
wherein each synchronization frame of the one or more synchronization frames includes information on an origin source address and a destination address to uniquely identify an originator and a destination for each synchronization frame;
wherein each synchronization frame includes a unique identifier whereby each portal AP and each satellite AP is configured to maintain a history of unique identifiers of the received synchronization frames to detect receiving the same synchronization frame more than once such that if a particular unique identifier is received more than once then the receiving AP is configured to drop the corresponding synchronization frame with said unique identifier;
wherein the one or more synchronization frames are proxied between at least two of: the one or more portal APs and the one or more satellite APs; and
wherein the proxied synchronization frames are forwarded to: the one or more portal APs and the one or more satellite APs while avoiding resending and receiving a frame of the proxied synchronization frames more than once.

2. The system of claim 1 , wherein at least one satellite AP is configured such that data sent from the switch to the at least one satellite AP is proxied through at least one portal AP within the channel blanket.

3. The system of claim 2 , wherein data sent from the switch to the satellite AP and through the portal AP, is further proxied through one or more satellite APs creating two or more wireless hops within the channel blanket.

4. The system of claim 1 , wherein at least one satellite AP is configured such that data sent from the satellite AP to the switch is proxied through the portal AP within the channel blanket.

5. The system of claim 2 , wherein data sent from the satellite AP to the switch is further proxied through one or more satellite APs before the portal AP creating two or more wireless hops within the channel blanket.

6. The system of claim 1 , wherein data sent from a first satellite AP of the one or more satellite APs to a second satellite AP of the one or more satellite APs is proxied through a first portal AP of the one or more portal APs in a sending AP area to a second portal AP of the one or more portal APs in a receiving AP area.

7. The system of claim 1 , wherein each proxied synchronization frame is duplicated and proxied multiple times throughout the single channel architecture via at least one of: wired links and wireless links.

8. The system of claim 7 , wherein each duplicated and proxied synchronization frame comprises a source address and a destination address.

9. The system of claim 8 , wherein each duplicated and proxied synchronization frame further comprises an original source address and an original destination address.

10. The system of claim 9 , wherein the original source address holds the source of an original frame of the proxied synchronization frames.

11. The system of claim 10 , wherein the original destination address holds a destination of the original frame of the proxied synchronization frames.

12. The system of claim 8 , wherein the source address identifies an originator of the proxied synchronization frame, wherein the originator is one of the one or more portal APs.

13. The system of claim 8 , wherein the source address identifies an originator of the proxied synchronization frame, wherein the originator is one of the one or more satellite APs.

14. The system of claim 8 , wherein the destination address identifies a destination of the proxied synchronization frame, wherein the destination address is one of the one or more portal APs.

15. The system of claim 8 , wherein the destination address identifies a destination of the proxied synchronization frame, wherein the destination address is one of the one or more satellite APs.

16. The system of claim 8 , wherein each duplicated and proxied synchronization frame comprises a unique identifier, wherein the one or more portal APs and the one or more satellite APs ignore duplicates of the unique identifier from a received proxied synchronization frame and prevent loops.

17. The system of claim 8 , wherein each proxied synchronization frame sent over the wireless LAN is encapsulated under a frame subtype.

18. The system of claim 17 , wherein the frame subtype is a vendor specific action frame.
