Abstract

The disclosed methods and systems use artificial intelligence (AI) and machine learning (ML) technologies to model the usage and interference on each channel. For example, units of the system can measure channel interference regularly over the time of day on all radios. The interference information is communicated to the base unit or a cloud server for pattern analysis. Interference measurements include interference from units within the system as well as interference from nearby devices. The base unit or the cloud server can recognize the pattern of the interference. Further, connected devices have a number of network usage characteristics observed and modeled including bitrate, and network behavior. These characteristics are used to assign channels to connected devices.

First claim

The invention claimed is:

1. A method comprising:
connecting, by a first access point, a mobile device to a small cell local area network via wireless communication wherein the first access point is one of a plurality of access points communicatively coupled in the small cell local area network;
maintaining a device history, by the plurality of access points, of the mobile device, the device history including recorded locations where the mobile device was previously stopped at for at least a threshold period of time;
predicting an endpoint of a first movement of the mobile device based on a predetermined degree of similarity between measured features of the first movement and a past movement of the mobile device, wherein the endpoint is a location that the mobile device ceased motion at an end of the past movement;
determining a second access point of the plurality of access points in the small cell local area network based on an identification of an access point of the plurality of access points that has a greatest historical strength of signal to the mobile device at the endpoint; and
roaming wireless communication of the mobile device, by the first access point, to the second access point of the plurality of access points.

2. The method of claim 1 , wherein the previously detected movement of the user device intersects a wireless communication range of the second access point.

3. The method of claim 1 ; wherein the endpoint of the is where wireless device signal strength with the second access point is greater or equal to every other access point of the plurality of access points.

4. The method of claim 1 , wherein the first movement includes a first starting point, said predicting further based on the past movement of the mobile device having a previous starting point similar to the first starting point.

5. The method of claim 1 , wherein the first movement includes a first vector, that first vector having a first direction, and the first direction points toward the second access point.

6. A method comprising:
propagating a small cell wireless mesh network (network) via a plurality of access points communicating via a backhaul channel;
generating, by the network, a predictive model for movement of devices that connect to the network based on respective historical movements and signal strengths of those devices, wherein the respective historical movements include recorded locations of each of the devices that connect to the network previously and that stopped for at least a threshold period of time; and
in response to connecting by a first access point of the plurality of access points to a first mobile device:
comparing a current movement of a first mobile device to a past movement of the first mobile device via the predictive model;
roaming the first mobile device to a second access point of the plurality of access points based on an indication from the predictive model that the second access point has a greatest signal strength for the network to the first mobile device at a location that the predictive model determines the first mobile device will physically remain for a threshold period.

7. The method of claim 6 , wherein the respective historical movements of a given user device intersects a wireless communication range of the second access point.

8. The method of claim 6 , wherein said comparing is further based on the current movement and the past movement having a shared starting point.

9. The method of claim 8 , wherein the current movement further includes a first vector, that first vector having a first direction, and the first direction points toward the second access point.

10. The method of claim 8 , wherein the current movement and the past movement have a shared directional vector of movement.

11. The method of claim 6 , wherein said roaming occurs prior to the second access point having the greatest signal strength for the network to the first mobile device.

12. The method of claim 6 , wherein the small cell, wireless mesh network is implemented in a home.

13. A system comprising:
a plurality of access points communicating via a backhaul channel that propagate a small cell wireless mesh network (network), the plurality of access points including a first access point and a second access point;
a memory communicatively coupled with the network and storing a predictive model corresponding to movement of devices that connect to the network based on respective historical movements and signal strengths of those devices, wherein the respective historical movements include recorded locations of each of the devices that connect to the network previously and that stopped for at least a threshold period of time; and
a processor configured to execute instructions stored in the memory that cause the first access point to roam a first mobile device connected thereto to the second access point based on an indication from the predictive model that the second access point has a greatest signal strength for the network to the first mobile device at a location that the predictive model determines the first mobile device will physically remain for a threshold period, the indication based on a comparison of a current movement of a first mobile device to a past movement of the first mobile device via the predictive model.

14. The system of claim 13 , wherein the respective historical movements of a given user device intersects a wireless communication range of the second access point.

15. The system of claim 13 , wherein the comparison caused by execution of the instructions stored in memory are further based on the current movement and the past movement having a shared starting point.

16. The system of claim 15 , wherein the current movement further includes a first vector, that first vector having a first direction, and the first direction points toward the second access point.

17. The system of claim 15 , wherein the current movement and the past movement have a shared directional vector of movement.

18. The system of claim 13 , wherein the instructions stored in memory executed by the processor further cause the roaming of the first mobile device prior to the second access point having the greatest signal strength for the network to the first mobile device.
