Abstract

A managed network supporting backscattering communication devices may be provided. A computing device may determine a plurality of locations respectively associated with a plurality of devices in a preterminal space. At least one of the plurality of devices may be power with energy transmitted from at least one Access Point (AP) to the least one of the plurality of devices at its location. Data may be received from the at least one of the plurality of devices in response to powering the at least one of the plurality of devices.

Claims (33)

1 . A method comprising:

receiving a plurality of device data respectively associated with a first plurality of devices in a preterminal space;

receiving a plurality of locations respectively associated with the first plurality of devices in the preterminal space;

communicating, based on the plurality device data and the plurality of locations, with the first plurality of devices in the preterminal space and with a second plurality of devices in the preterminal space, wherein communicating further comprises coordinating communication to minimize cross-interference between the first plurality of devices and the second plurality of devices, and wherein coordinating communication to minimize cross-interference comprises insuring that a radio medium for any Access Point (AP) is not being used by any of the second plurality of devices when any of the first plurality of devices are transmitting on the radio medium;

determining which APs of a plurality of APs are to be used in communicating with a one of the first plurality of devices based on an iterative process that maximizes a Signal-to-Noise (SNR) ratio of the first plurality of devices and the second plurality of devices, wherein determining which APs of a plurality of APs are to be used in communicating with a one of the first plurality of devices comprises:

determining which first APs of the plurality of APs to be used for powering the one of the first plurality of devices,

determining which second APs of the plurality of APs to be used for Wi-Fi communication,

determining which third APs of the plurality of APs to be used for listening to signals from the one of the first plurality of devices, and

maximizing the SNR of the first plurality of devices and second plurality of devices based on the SNR of Wi-Fi communication signals and signals from the one of the first plurality of devices.

2 . The method of claim 1 , wherein insuring is performed by a controller.

3 . The method of claim 1 , wherein insuring is performed by an AP.

4 . The method of claim 1 , wherein the first plurality of devices comprise backscatter devices.

5 . The method of claim 1 , wherein the first plurality of devices comprise energy harvesting devices.

6 . The method of claim 1 , wherein the first plurality of devices comprise a combination of backscatter devices and energy harvesting devices.

7 . The method of claim 1 , wherein the second plurality of devices comprise wireless devices.

8 . The method of claim 1 , wherein the second plurality of devices comprises Wi-Fi devices.

9 . A method comprising:

monitoring for an unscheduled communication from a device;

reporting the unscheduled communication to a controller; and

allocating, by the controller, an Access Point (AP) to support the unscheduled communication according to configured management policies, wherein allocating the AP to support the unscheduled communication comprises:

adapting, by the controller, power and time allocation of a nearby AP to the device to support the unscheduled communication from the device, and

adapting, by the controller, power and time allocation of another nearby AP to the device to contrast the unscheduled communication from the device.

10 . The method of claim 9 , wherein the device comprises one of a backscatter device and an energy harvesting device.

11 . The method of claim 9 , wherein monitoring for the unscheduled communication from the device comprises monitoring for the unscheduled communication from the device using monitoring capabilities of APs.

12 . A system comprising:

a memory storage; and

a processing unit disposed in a controller and coupled to the memory storage, wherein the processing unit is operative to:

receive a report of an unscheduled communication from a device; and

allocate an Access Point (AP) to support the unscheduled communication according to configured management policies, wherein allocating the AP to support the unscheduled communication comprises:

adapt power and time allocation of a nearby AP to the device to support the unscheduled communication from the device, and

adapt power and time allocation of another nearby AP to the device to contrast the unscheduled communication from the device.

13 . The system of claim 12 , wherein the device comprises one of a backscatter device and an energy harvesting device.

14 . The system of claim 12 , wherein monitoring capabilities of APs are used to monitor for the unscheduled communication from the device.
