Wireless extender secure discovery and provisioning
View Patent ↗According to embodiments of the invention, a first wireless access point discovers a second wireless access point, the first wireless access point tunes its radio and privacy settings, without user input, based upon parameters automatically exchanged in response to the discovery of the second wireless access point, and a secure direct wireless connection is established between the first and second wireless access points using the radio and privacy settings. Adding the first wireless to an existing mesh network includes a determination of the best available direct wireless connection.
1. A method for an additional wireless access point to wirelessly connect to a best candidate wireless access point, the method comprising:
receiving a plurality of individual broadcast beacons by an additional wireless access point from a plurality of individual wireless access points, wherein each of the plurality of individual wireless access points transmits a unique beacon;
authenticating by the additional wireless access point advertisement information in each unique beacon;

receiving a probe response by the additional wireless access point from each of the plurality of individual wireless access points;
measuring a mean received signal strength of each of the plurality of individual wireless access points;
calculating a weight for each of the plurality of individual wireless access points, wherein the calculation of the weight of any particular wireless access point includes the measured mean received signal strength from that particular wireless access point;
selecting the wireless access point with a largest weight as the best candidate wireless access point; and
connecting to the best candidate wireless access point with the largest weight by the additional wireless access point.
2. The method of claim 1 , wherein the weight calculated for an individual wireless access point corresponds to the measured mean received signal strength of that individual wireless access point, wherein a higher mean received signal strength corresponds to a larger calculated weight.
3. The method of claim 1 , wherein the advertisement information for each of the wireless access points broadcasting a beacon includes at least one of an element identification, an advertisement length, a vendor identification, or a payload field.
4. The method of claim 3 , wherein the payload field includes at least one of a protocol field, a software version, a hardware version, a hop count, a nonce, a number of wireless stations already connected to the particular wireless access point, or an access point public key of the particular wireless access point.
5. The method of claim 4 , wherein the calculating of the weight of any of the particular wireless access points also includes the number of wireless stations already connected to the particular wireless access point, or the hop count of the particular wireless access point.
6. The method of claim 1 , wherein each of the plurality of individual wireless access points broadcasting a unique beacon are wireless root access points.
7. The method of claim 6 , further comprising the additional wireless access point broadcasting a new unique beacon after connecting to the best candidate wireless access point, wherein the additional wireless access point is a wireless root access point, and wherein the new unique beacon includes advertisement information.
8. The method of claim 6 , wherein the additional wireless access point is a wireless extender.
9. The method of claim 8 , wherein the wireless extender does not broadcast a beacon.
10. The method of claim 1 , further comprising:
connecting to one of the plurality of individual wireless access points by a wireless station;
roaming between wireless access points by the wireless station, wherein the wireless station roams between the wireless access points without changing the wireless stations radio or privacy settings.
11. A non-transitory computer readable storage medium embodied thereon a program executable to perform a method for an additional wireless access point to wirelessly connect to a best candidate wireless access point, the method comprising:
receiving a plurality of individual broadcast beacons by an additional wireless access point from a plurality of individual wireless access points, wherein each of the plurality of individual wireless access points transmits a unique beacon;
authenticating by the additional wireless access point advertisement information in each unique beacon;
transmitting a probe request from the additional access point to each of the plurality of individual wireless access points by the additional wireless access point;
receiving a probe response by the additional wireless access point from each of the plurality of individual wireless access points;
measuring a mean received signal strength of each of the plurality of individual wireless access points;
calculating a weight for each of the plurality of individual wireless access points, wherein the calculation of the weight of any particular wireless access point includes the measured mean received signal strength from that particular wireless access point;
selecting the wireless access point with a largest weight as the best candidate wireless access point; and
connecting to the best candidate wireless access point with the largest weight by the additional wireless access point.
12. The non-transitory computer readable storage medium method of claim 11 , wherein the weight calculated for an individual wireless access point corresponds to the measured mean received signal strength of that individual wireless access point, wherein a higher mean received signal strength corresponds to a larger calculated weight.
13. The non-transitory computer readable storage medium method of claim 11 , wherein the advertisement information for each of the wireless access points broadcasting a beacon includes at least one of an element identification, an advertisement length, a vendor identification, or a payload field.
14. The non-transitory computer readable storage medium method of claim 13 , wherein the payload field includes at least one of a protocol field, a software version, a hardware version, a hop count, a nonce, a number of wireless stations already connected to the particular wireless access point, or an access point public key of the particular wireless access point.
15. The non-transitory computer readable storage medium method of claim 14 , wherein the calculating of the weight of any of the particular wireless access points also includes the number of wireless stations already connected to the particular wireless access point, or the hop count of the particular wireless access point.
16. The non-transitory computer readable storage medium method of claim 11 , wherein each of the plurality of individual wireless access points broadcasting a unique beacon are wireless root access points.
17. The non-transitory computer readable storage medium method of claim 16 , the program further executable to broadcast from the additional wireless access point a new unique beacon after connecting to the best candidate wireless access point, wherein the additional wireless access point is a wireless root access point, and wherein the new unique beacon includes advertisement information.
18. The non-transitory computer readable storage medium method of claim 16 , wherein the additional wireless access point is a wireless extender.
19. The non-transitory computer readable storage medium method of claim 18 , wherein the wireless extender does not broadcast a beacon.
20. The non-transitory computer readable storage medium method of claim 11 , the program further executable to:
connect to one of the plurality of individual wireless access points by a wireless station;
roam between wireless access points by the wireless station, wherein the wireless station roams between the wireless access points without changing the wireless stations radio or privacy settings.
