## Abstract

Example implementations relate to an access point (AP) that can via up from power save mode via a including Bluetooth low energy (BLE) system-on-chip (SoC) within the AP. The AP can include a power source, a power reset logic component in communication with the power source, a BLE SoC, a processor, and a non-transitory memory resource instructions executable by the processor that signals the AP is in a power save mode, receives an indication, via the BLE SoC, to wake up the AP, and wake up, via the BLE SoC, the AP in response to receiving the indication.

## Claims

### Claim 1

An access point (AP), comprising:
a power source;
a power reset logic component in communication with the power source; and
a bluetooth low energy (BLE) system-on-chip (SoC) in communication with the power source and the power reset logic component;
a processor; and
a memory resource storing machine readable instructions executable by the processor to:
receive, from the power reset logic component, information that signals the AP is in a power save mode;
receive, via the BLE SoC, an indication to wake up the AP; and
wake up, via the BLE SoC, the AP in response to receiving the indication.

### Claim 2 (depends on 1)

The AP of claim 1, wherein the indication is received in response to:
a timer indicating to wake up the AP in response to the timer reaching an elapsed amount of time;
a mobile device indicating to wake up the AP in response to detecting the AP in the power save mode; and
an alert data received from an additional device in response to the additional device being unable to meet a network capacity.

### Claim 3 (depends on 2)

The AP of claim 2, wherein the additional device comprises one of an access point, mobile application, a network device, a wireless transmitter, a network controller or combination thereof.

### Claim 4 (depends on 1)

The AP of claim 1, wherein the AP advertises to the additional device that the AP is in the power save mode, wherein the advertisement includes broadcasting small packets of data via a beacon frame which includes a universally unique identifier (UUID).

### Claim 5 (depends on 1)

The AP of claim 1, wherein the AP receives information associated with a power status of the power source associated with the AP.

### Claim 6 (depends on 1)

The AP of claim 1, wherein the BLE SoC is powered via the power source.

### Claim 7 (depends on 1)

The AP of claim 1, wherein the BLE SoC is located within the AP.

### Claim 8

A method comprising:
entering an access point (AP) into a power save mode;
activating a timer, via a Bluetooth low energy (BLE) system-on-chip (SoC), within the AP in response to detecting the AP is in the power save mode;
monitoring the timer to determine an elapsed period of time;
determining, in response to the elapsed period of time, to bring the AP out of the power save mode;
transmitting a signal, via the BLE SoC, indicating to bring the AP out of the power save mode; and
waking up the AP via the BLE SoC.

### Claim 9 (depends on 8)

The method of claim 8, wherein the elapsed period of time comprises a period of time that the AP is in the power save mode.

### Claim 10 (depends on 8)

The method of claim 8, wherein the timer is programmed to activate at set time intervals.

### Claim 11 (depends on 8)

The method of claim 8, wherein the timer is activated by a user.

### Claim 12 (depends on 10)

The method of claim 10, wherein the set time intervals comprise at least one of a minute, an hour, and a day.

### Claim 13 (depends on 8)

The method of claim 8, wherein the AP is in a network outside of reach of Wake on LAN (WoL) frame.

### Claim 14

A system, comprising:
a first access point (AP) comprising:
a first processor; and
a first memory resource storing machine readable instructions executable by the first processor to:
enter into a power save mode;
advertise, via a bluetooth low energy (BLE) system-on-chip (SoC) within the first AP, information indicating the first AP is in the power save mode to a second AP; and
the second AP comprising:
a second processor; and
a second memory resource storing machine readable instructions executable by the second processor to:
determine a network demand associated with the second AP;
receive the information advertised via the BLE SoC within the first AP;
in response to the second AP being unable to meet the network demand associated with the second AP, determine to wake up the first AP from the power save mode; and
send a message to the BLE SoC of the first AP to wake up the first AP.

### Claim 15 (depends on 14)

The system of claim 14, wherein the second AP is controlled via a network controller.

### Claim 16 (depends on 14)

The system of claim 14, wherein the second AP includes a second BLE SoC.

### Claim 17 (depends on 14)

The system of claim 14, wherein the instructions of the second memory resource are executable to instruct the second processor to broadcast network demand information associated with the second AP to the first AP.

### Claim 18 (depends on 14)

The system of claim 14, wherein the instructions of the first memory resource are executable to instruct the first processor to receive an advertisement from the second AP when the first AP is in the power save mode.

### Claim 19 (depends on 14)

The system of claim 14, wherein the instructions of the second memory resource are executable to instruct the second processor to activate the second AP, via a mobile application, in response to determining the first AP is in the power save mode.

### Claim 20 (depends on 14)

The system of claim 14, wherein the first AP wakes up via activation of a subsystem within the first AP.
