Abstract

A wireless gateway for steering a client device between content streaming apparatuses in a wireless local area network (WLAN). The gateway provides an access point (GW AP) including a gateway steering controller configured to determine whether a client device should be steered to a content streaming apparatus based on at least one sample measurement on received signal strength between the client device and the content streaming apparatus and at least one other content streaming apparatus, and conduct steering logic calculations. The steering logic calculations are compared against predetermined thresholds, and said gateway steering controller provides an instruction to steer the client device to one of the content streaming apparatuses based on a difference between the steering logic calculations and the predetermined thresholds. Optionally, the gateway steering controller may also provide band steering as well as signal strength steering.

First claim

What is claimed is:

1. A wireless gateway for steering a client device between content streaming apparatuses in a wireless local area network (WLAN), the wireless gateway comprising:
a gateway steering controller configured to determine whether to steer a client device to a content streaming apparatus based on at least one sample measurement of received signal strength on a first Wi-Fi radio band between the client device and the content streaming apparatus and at least one other content streaming apparatus, and configured to conduct steering logic calculations based on the at least one sample measurement, the steering logic calculations including using the received signal strength measured on the first Wi-Fi radio band-to estimate a received signal strength on a second Wi-Fi radio band,
wherein the at least one sample measurement is based on information obtained by the gateway steering controller from the content streaming apparatuses, and the steering logic calculations are compared against predetermined thresholds, and
the gateway steering controller provides an instruction to steer the client device to the first Wi-Fi radio band or the second Wi-Fi radio band of one of the content streaming apparatuses based on a difference between the steering logic calculations and the predetermined thresholds.

2. The wireless gateway as recited by claim 1 , wherein the gateway steering controller is configured to initiate steering logic following a connection of the content streaming apparatus with the client device.

3. The wireless gateway as recited by claim 1 , wherein the sample measurement includes received signal strengths (RSSI), and
the content streaming apparatus comprises a steering client configured to perform at least one sample measurement including RSSI which is transmitted to the gateway steering controller.

4. The wireless gateway as recited by claim 1 , wherein traffic flow through the content streaming apparatus is monitored by the wireless gateway based on a capacity threshold, and
wherein when the traffic flow through to the content streaming apparatus is greater than a first percentage of the capacity threshold, the content streaming apparatus is selected for band steering thereby causing the content streaming apparatus to communicate with a higher or lower frequency.

5. The wireless gateway as recited by claim 1 , wherein traffic flow through the content streaming apparatus is monitored by the wireless gateway based on a capacity threshold, and
wherein when the traffic flow through to the content streaming apparatus is greater than a second percentage of the capacity threshold, the content streaming apparatus is selected for steering from the content streaming apparatus to another content streaming apparatus.

6. The wireless gateway as recited by claim 1 , wherein the wireless gateway and the content streaming apparatus are linked by a security communications link.

7. The wireless gateway as recited by claim 1 , wherein the wireless gateway is configured to recognize a low signal strength between the client device and the content streaming apparatus and steer the client device from the content streaming apparatus to another content streaming apparatus, and
wherein the low signal strength is less than −70 dBm, as measured by RSSI.

8. The wireless gateway as recited by claim 1 , wherein the wireless gateway is configured to steer the client device from one content streaming apparatus to another and steer the client device onto a different bandwidth.

9. The wireless gateway as recited by claim 1 , wherein the wireless gateway is configured to communicate with associated content streaming apparatuses and one or more non-associated content streaming apparatuses, and
wherein the gateway steering controller is configured to steer the client device from one content streaming apparatus to another, associated or non-associated.

10. A content streaming apparatus comprising:
an input for receiving an input signal;
a wireless controller configured to communicate via wireless with a client device, and receive from the client device a streaming session request for streaming of requested content;
at least one tuner;
a controller configured to establish a streaming session with the client device via the wireless controller, and send the requested content to the client device in the streaming session; network connection circuitry; and
a gateway steering controller configured to determine whether to steer the client device to another content streaming apparatus based on at least one sample measurement of received signal strength on a first Wi-Fi radio band between the client device and the content streaming apparatus and at least one other content streaming apparatus, and configured to conduct steering logic calculations based on the at least one sample measurement, the steering logic calculations using the received signal strength measured on the first Wi-Fi radio band to estimate a received signal strength on a second Wi-Fi radio band,
wherein the at least one sample measurement is based on information obtained by the gateway steering controller from the content streaming apparatuses, and steering logic calculations are compared against predetermined thresholds, and the gateway steering controller provides an instruction to steer the client device to the first Wi-Fi radio band or the second Wi-Fi radio band of one of the content streaming apparatuses based on a difference between the steering logic calculations and the predetermined thresholds.

11. The content streaming apparatus as recited by claim 10 , wherein the gateway steering controller is configured to initiate steering logic following connection of the content streaming apparatus with the client device.

12. The content streaming apparatus as recited by claim 10 , wherein the sample measurement includes received signal strengths (RSSI), and
the content streaming apparatus comprises a steering client configured to perform at least one sample measurement including RSSI which is transmitted to the gateway steering controller.

13. The content streaming apparatus as recited by claim 10 , wherein traffic flow through the content streaming apparatus is monitored by the gateway steering controller based on a capacity threshold, and
wherein when the traffic flow through to the content streaming apparatus is greater than a first percentage of the capacity threshold, the content streaming apparatus is selected for band steering thereby causing the content streaming apparatus to communicate with a higher or lower frequency.

14. The content streaming apparatus as recited by claim 10 , wherein traffic flow through of the content streaming apparatus is monitored by the wireless gateway based on a capacity threshold, and
wherein when the traffic flow through to the content streaming apparatus is greater than a second percentage of the capacity threshold, the content streaming apparatus is selected for steering from the content streaming apparatus to another content streaming apparatus.

15. The content streaming apparatus as recited by claim 10 further comprising a blacklist adapted to disassociate a STA with a current AP or frequency band.

16. The content streaming apparatus as recited by claim 15 , wherein a blacklisting procedure minimizes searching of APs for band steering.

17. The content streaming apparatus as recited by claim 10 , wherein the predetermined thresholds comprise:
a. A 1 , comprising a threshold below which steering from an existing content streaming apparatus connection is considered configurable, with d
