Abstract

Systems, devices, and methods for two or more access points (APs), where each AP comprises: at least one LAN port for connection to the wired network; at least one LAN port for connection between at least one other AP; a processor having addressable memory, where the processor of a first AP of the two or more APs is configured to: select the first AP of the two or more APs as a primary AP; select the second AP of the two or more APs as a back-up AP; detect, via a trigger, a failure of the primary AP; and configure the second AP as the primary AP and the first AP as the back-up AP if the failure of the first AP is detected.

First claim

What is claimed is:

1. A system comprising:
two or more access points (APs), wherein each AP comprises:
at least one LAN port configured to connect to a network including a wired network;
at least one LAN port configured to connect between at least one other AP;
a processor having addressable memory, wherein the processor of a first AP of the two or more APs is configured to communicate with the processor of a second AP of the two or more APs over a hot sync cable, and wherein the processors of the APs are configured to:
select the first AP of the two or more APs as a primary AP;
select the second AP of the two or more APs as a back-up AP;
detect, via a trigger, a failure of the primary AP, wherein the connection to a local network is via an Ethernet cable, and wherein the detected failure of the primary AP comprises a failure of the Ethernet cable between the primary AP and the backup AP; and
configure the second AP as the primary AP and the first AP as the back-up AP if the failure of the first AP is detected.

2. The system of claim 1 , wherein the two or more APs are configured to tune to the same radio frequency (RF) channel or frequency.

3. The system of claim 1 , wherein each of the two or more APs are configured to provide wireless connections to one or more user devices.

4. The system of claim 1 , wherein the at least one LAN port configured to connect between at least one other AP is a general-purpose input/output (GPIO) port.

5. The system of claim 1 , wherein the back-up AP is configured to receive frames, and wherein the back-up AP is configured to not transmit frames.

6. The system of claim 1 , wherein the connection between the APs is via the hot sync cable.

7. The system of claim 6 , wherein the hot sync cable is an Ethernet cable.

8. The system of claim 1 , wherein the connection between the APs is wireless.

9. The system of claim 1 further comprising:
a hub configured to be in communication with each of the two or more APs via each of the at least one LAN ports for Ethernet connection to the local network, wherein the hub is configured to be directly connected to the local network.

10. A system comprising:
two or more access points (APs), wherein each AP comprises:
at least one LAN port configured to connect to a hub;
at least one LAN port configured to connect between at least one other AP;
a processor having addressable memory, wherein the processor of a first AP of the two or more APs is configured to communicate with the processor of a second AP of the two or more APs over a hot sync cable, and wherein the processors of the APs are configured to:
select the first AP of the two or more APs as a primary AP;
select the second AP of the two or more APs as a back-up AP;
detect, via a trigger, a failure of the primary AP; and
configure the second AP as the primary AP and the first AP as the back-up AP if the failure of the first AP is detected;

wherein the hub is configured to be in communication with each of the two or more APs via each of the at least one LAN ports, wherein the hub is directly connected to the local network, and wherein the hub is configured to be directly connected to the local network via a single cable.

11. A system comprising:
a first access point (AP) of two or more access points (APs), wherein the first AP comprises:
at least one LAN port configured to connect to a local network;
at least one LAN port configure to connect between at least one other AP via a hot sync cable;
a processor having addressable memory, the processor configured to:
select the first AP of the two or more APs as a primary AP;
detect a failure of the first AP;
send a signal via the hot sync cable based on the detected failure;
configure the first AP of the two or more APs as a back-up AP;

a second (AP) of two or more access points (APs), wherein the second AP comprises:
at least one LAN port configured to connect to the local network;
at least one LAN port configured to connect between at least one other AP via the hot sync cable;
a processor having addressable memory, the processor configured to:
select the second AP of the two or more APs as a back-up AP;
receive a signal from the first AP based on the detected failure;
configure the second AP of the two or more APs as a primary AP;

a hub configured to communicate with each of the two or more APs via each of the at least one LAN ports for Ethernet connection to the local network, wherein the hub is directly connected to the local network, and wherein the hub is directly connected to the local network via a single cable.

12. The system of claim 11 , wherein the back-up AP is configured to receive frames, and wherein the back-up AP is configured to not transmit frames.
