Abstract

Automatically changing Access Point (AP) system configurations for Power over Ethernet (PoE) adaptation and Radio Frequency (RF) power improvement on band edge channels, particularly for Wireless Local Area Networks (WLAN) may be provided. A PoE budget for an AP may be determined. Then, an evaluation of inputs associated with the AP may be performed. The evaluation may include determining an entity input from an entity associated with the AP, determining a client input from a client interfacing with the AP, and/or determining a device input from the AP. Next, a configuration of the AP may be determined based on the PoE budget and the entity input, the client input, and/or the device input. The operation of the AP may be altered based on the configuration.

First claim

The invention claimed is:

1 . A method comprising:
determining a Power over Ethernet (PoE) budget for an Access Point (AP), wherein determining the PoE budget for the AP comprises determining a standard of a plurality of standards the AP is operating under, and wherein each of the plurality of standards comprises an associated PoE budget; performing an evaluation of inputs associated with the AP, the evaluation comprising any one of:
(i) determining an entity input from an entity associated with the AP,
(ii) determining a client input from a client interfacing with the AP,
(iii) determining a device input from the AP, or
(iv) any combination of (i)-(iii);
determining a configuration of the AP based on any one of (v) the entity input, (vi) the client input, (vii) the device input, or (viii) any combination of (v)-(vii) to meet the PoE budget; and altering an operation of the AP based on the configuration, wherein altering the operation of the AP based on the configuration comprises determining an AP feature of the AP to alter based on entity preference, and wherein altering the operation of the AP based on the configuration comprises switching at least one radio from a first chain to a second chain to reduce an AP power.

2 . The method of claim 1 , further comprising:
detecting a change in the inputs associated with the AP; determining a new configuration of the AP based on the change; and altering the operation of the AP based on the new configuration.

3 . The method of claim 1 , further comprising periodically performing the evaluation to determine a change in the inputs.

4 . The method of claim 1 , further comprising continuously performing the evaluation to determine a change in the inputs.

5 . The method of claim 1 , wherein determining the entity input from the entity associated with the AP comprises any one of (i) determining a device is connected to the AP, (ii) determining an AP feature is selected to be enabled by the entity, (iii) determining an antenna configuration of the AP, (iv) determining a feature is incompatible with a system deployed in the same field as the AP, or (v) any combination of (i)-(iv).

6 . The method of claim 1 , wherein determining the client input from the client interfacing with the AP comprises:
determining a link budget of the client; determining a distribution of clients interfacing with a radio of the AP, including the client; and determining a grouping of the clients based on the distribution, wherein determining the configuration of the AP is based on the link budget and the grouping.

7 . The method of claim 1 , wherein determining the client input from the client interfacing with the AP comprises determining a duty cycle of packets the AP is scheduling, wherein determining the configuration of the AP is based on the duty cycle.

8 . The method of claim 1 , wherein determining the device input from the AP comprises any one of (i) determining an operating frequency of the AP, (ii) determining a loss caused by a component of the AP, (iii) determining an operating temperature of the AP, (iv) determining an ambient temperature of the AP, (v) or any combination of (i)-(iv).

9 . The method of claim 8 , wherein determining the configuration of the AP comprises determining a new operating frequency of the AP based on the device input.

10 . A system comprising:
a memory storage; and a processing unit coupled to the memory storage, wherein the processing unit is operative to: determining a Power over Ethernet (PoE) budget for an Access Point (AP), wherein determining the PoE budget for the AP comprises determining a standard of a plurality of standards the AP is operating under, and wherein each of the plurality of standards comprises an associated PoE budget; performing an evaluation of inputs associated with the AP, the evaluation comprising any one of:
(i) determining an entity input from an entity associated with the AP,
(ii) determining a client input from a client interfacing with the AP,
(iii) determining a device input from the AP, or
(iv) any combination of (i)-(iii);
determining a configuration of the AP based on any one of (v) the entity input, (vi) the client input, (vii) the device input, or (viii) any combination of (v)-(vii) to meet the PoE budget; and altering an operation of the AP based on the configuration, wherein altering the operation of the AP based on the configuration comprises determining an AP feature of the AP to alter based on entity preference, and wherein altering the operation of the AP based on the configuration comprises switching at least one radio from a first chain to a second chain to reduce an AP power.

11 . The system of claim 10 , wherein the processing unit is further operative to:
detect a change in the inputs associated with the AP; determine a new configuration of the AP based on the change; and alter the operation of the AP based on the new configuration.

12 . The system of claim 10 , wherein the processing unit is further operative to periodically or continuously performing the evaluation to determine a change in the inputs.

13 . The system of claim 10 , wherein the processing unit being operative to determine the client input from the client interfacing with the AP comprises the processing unit being operative to:
determine a link budget of the client; determine a distribution of clients interfacing with a radio of the AP, including the client; and determine a grouping of the clients based on the distribution, wherein determining the configuration of the AP is based on the link budget and the grouping.

14 . The system of claim 10 , wherein the processing unit being operative to determine the client input from the client interfacing with the AP comprises the processing unit being operative to determine a duty cycle of packets the AP is scheduling, wherein the configuration of the AP is determined based on the duty cycle.

15 . The system of claim 10 , wherein the processing unit being operative to determine the configuration of the AP comprises the processing unit being operative to determining a new operating frequency of the AP based on the device input.

16 . A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
determining a Power over Ethernet (PoE) budget for an Access Point (AP), wherein determining the PoE budget for the AP comprises determining a standard of a plurality of standards the AP is operating under, and wherein each of the plurality of standards comprises an associated PoE budget; performing an evaluation of inputs associated with the AP, the evaluation comprising any one of:
(i) determining an entity input from an entity associated with the AP,
(ii) determining a client input from a client interfacing with the AP,
(iii) determining a device input from the AP, or
(iv) any combination of (i)-(iii);
determining a configuration of the AP based on any one of (v) the entity input, (vi) the client input, (vii) the device input, or (viii) any combination of (v)-(vii) to meet the PoE budget; and altering an operation of the AP based on the configuration, wherein altering the operation of the AP based on the configuration comprises determining an AP feature of the AP to alter based on entity preference, and wherein altering the operation of the AP based on the configuration comprises switching at least one radio from a first chain to a second chain to reduce an AP power.
