WI-FI POWER REDUCTION SYSTEM, METHOD AND MEDIA
A server includes a processor configured to execute instructions stored on a memory to cause the server to: receive a client position signal; predict a future position of a client device based on a client device position signal providing location and velocity information about the client device; instruct a first access point device to provide a first Wi-Fi hotspot network with a first SSID, currently in use by the client device with another access point device, based on the predicted future position of the client device; and instruct a second access point device, which was previously providing a second Wi-Fi hotspot network with the first SSID, to stop providing the second Wi-Fi hotspot network with the first SSID after instructing the first access point device to provide the first Wi-Fi hotspot network with the first SSID.
Embodiments of the invention relate to Wi-Fi hotspot networks.
A multiple-system operator (MSO) is an operator of multiple cable or direct-broadcast satellite television systems. MSO’s and other vendors are beginning to deploy outdoor Wi-Fi access point devices in dense urban areas, sports arenas, train stations, airports, etc. A Wi-Fi access point device (APD) is a networking hardware device that allows other Wi-Fi devices to connect to a wired network. The APD usually connects to a router (via a wired network) as a standalone device, but it can also be an integral component of the router itself. An APD is differentiated from a hotspot which is a physical location where Wi-Fi access is available. These APDs permit the MSO to offer hotspot services to their customers. Thus connecting to the MSO’s data networks, instead of using their respective mobile data plan, can save the user significant cellular overage charges.
SUMMARYAspects of the present invention are drawn to a server for use with a plurality of client devices, a plurality of access point devices and a client device position signal associated with a client device of the plurality of client devices. Each access point device is configured to provide a respective plurality of Wi-Fi hotspot networks. Each of the plurality of Wi-Fi hotspot networks has a respective SSID. The client device position signal provides location and velocity information about the client device. The server includes a memory and a processor configured to execute instructions stored on the memory to cause the server to: receive the client device position signal; predict a future position of the client device based on the client device position signal providing location and velocity information about the client device; instruct a first access point device to provide a first Wi-Fi hotspot network with a first SSID, currently in use by the client device with another access point device, based on the predicted future position of the client device; and instruct a second access point device, which was previously providing a second Wi-Fi hotspot network with the first SSID, to stop providing the second Wi-Fi hotspot network with the first SSID after instructing the first access point device to provide the first Wi-Fi hotspot network with the first SSID.
The accompanying drawings, which are incorporated in and form a part of the specification, illustrate example embodiments and, together with the description, serve to explain the principles of the invention. In the drawings:
As mentioned above, MSOs and other vendors are beginning to deploy outdoor Wi-Fi access point devices in dense urban areas, sports arenas, train stations, airports, etc. However, in order to provide full coverage across an urban area, an MSO might deploy one or two outdoor APDs per city block. The MSOs that provide these outdoor APDs have, in turn, created secondary revenue streams by reselling data bandwidth to what could be seen as competitors. One outdoor APD could provide 4, 8 or 16 SSIDs on a single radio (2.4 or 5 GHz). However, there are inefficiencies when transmitting multiple SSIDs. For each SSID, beacons must be transmitted, and it is theoretically possible that entire radio bandwidth could be consumed just transmitting beacons on all the SSIDs. Additionally, a significant amount of electrical power is wasted transmitting beacons to non-existent clients.
As shown in the figure, city 100 includes: a plurality of eastbound-westbound streets, a sample of which are indicated as streets 102, 104, 106 and 108; a plurality of northbound-southbound streets, a sample of which are indicated as streets 110 and 112; a plurality of client devices 114, 116, 118 and 120 and a plurality of APDs, a sample of which are indicated as APDs A2, A4, A6 and A8. It should be noted that, or the purposes of discussion only, this example includes users having the respective four client devices 114, 116, 118 and 120, but this could easily be 1000 users with respective 1000 client devices.
As shown in the figure, APD A2 includes a controller 206, a radio 208, an interface circuit 210, and a memory 212, which includes controller executable instructions 214 stored therein. Client device 120 includes a controller 216, a display 218, a radio 220, an interface circuit 222 and a memory 224, which includes controller executable instructions 226 stored therein. Further, any of the APDs in
Controller 206 can include a dedicated control circuit, CPU, microprocessor, etc. Controller 206 controls the circuits of APD A2. Memory 212 can store various programming, and user content, and data as stored data 214. Interface circuit 210 can include one or more connectors, such as RF connectors, or Ethernet connectors, and/or wireless communication circuitry, such as 5G circuitry and one or more antennas. Interface circuit 210 receives service from a service provider by known methods, non-limiting examples of which include terrestrial antenna, satellite dish, wired cable, DSL, optical fibers, or 5G as discussed above. Through interface circuit 210, APD A2 receives an input signal, including data and/or audio/video content, from the service provider and can send data to the service provider.
Radio 208 (and preferably two or more radios) may also be referred to as a wireless communication circuit, such as a Wi-Fi WLAN interface radio transceiver, and is operable to communicate with client devices, such as client device 120. Radio 208 includes one or more antennas and communicates wirelessly via one or more of the 2.4 GHz band, the 5 GHz band, and the 6 GHz band, or at the appropriate band and bandwidth to implement the Wi-Fi 4, 5, 6, or 6E protocols. APD A2 can also be equipped with a radio to implement a Bluetooth interface radio transceiver and antenna, which communicates wirelessly in the ISM band, from 2.400 to 2.485 GHz. As an alternative, at least one of the radios can be a radio meeting a Radio Frequency For Consumer Electronics (RF4CE) protocol, Zigbee protocol, and/or IEEE 802.15.4 protocol, which also communicates in the ISM band.
In client device 120, controller 216, which can include a dedicated control circuit, CPU, microprocessor, etc., controls the circuits of client device 120. Memory 224 can store various programming, and user content, and data as stored data 226. Radio 220 may include a Wi-Fi WLAN interface radio transceiver that is operable to communicate with APD A2 and also may include a cellular transceiver operable to communicate with cellular service provider through a cellular network. Radio 220 includes one or more antennas and communicates wirelessly via one or more of the 2.4 GHz band, the 5 GHz band, and the 6 GHz band, or at the appropriate band and bandwidth to implement the Wi-Fi 4, 5, 6, or 6E protocols. Client device 120 can also be equipped with a radio to implement a Bluetooth interface radio transceiver and antenna, which communicates wirelessly in the ISM band, from 2.400 to 2.485 GHz. As an alternative, at least one of the radios can be a RF4CE protocol, Zigbee protocol, and/or IEEE 802.15.4 protocol, which also communicates in the ISM band. Further, any of the client devices in
Further, in this example, there are only four people walking thru the city, so it is highly inefficient to transmit on all APDs (24) and with both radios (2.4 and 5 GHz). At peak periods, there may be 1000 users, and all 24 APDs may be in use.
Some MSOs offer their subscribers a Wi-Fi anywhere feature. This allows an individual subscriber to connect to any APD within the MSO’s footprint. Further, some MSOs may resell surplus bandwidth/SSIDs on their outdoor APDs. For example, an MSO may rent network capacity to up to 7 other competitors. Each of these vendors is given a unique SSID on both 2.4 and 5 GHz bands. All SSIDs are beaconing at the standard rates. Thus, assuming there are 8 SSIDs, 32% of the bandwidth is being consumed by the beacons alone (2.4 GHz). This bandwidth is being consumed by beacons alone, and not consumed by data being sent to or from clients.
What is needed is a system and method to reduce the bandwidth consumed by multiple beacon transmission and to reduce power consumption of unused radio transmitters.
A system and method in accordance with the present disclosure reduces the bandwidth consumed by multiple beacon transmission and reduces power consumption of unused radio transmitters.
In accordance with the present disclosure, an APD only broadcasts a Wi-Fi network as needed, based on a received probe request or an activation signal from a service provider indicating that a user will likely need the Wi-Fi network in the near future.
Most clients can actively or passively scan for an APD. In an active scan session, the client sends out probe request broadcasts looking for any APD, and an APD responds via probe response messages. In the case of a passive scan, the only looks for Wi-Fi beacons, and upon encountering one it has connected to in the past, initiates a reconnection sequence.
Given that it is unlikely that an APD would have clients connected on all SSIDs that may be simultaneously provided by the APD, e.g., 8 SSIDs, overall traffic/throughput could be reduced by removing unnecessary beacons. An unnecessary beacon may be a beacon transmitted to non-existing clients. While beacons contain other necessary information, transmission of the beacons may be suspended until needed. That is, the APD will stop sending beacons until a probe request is received from a client device. Once a client device makes a probe request, and the APD responds, beacons will start on the SSID in question, and connections will be permitted.
Energy consumption may be further reduced by shutting off transmitters of all radios that are not connected to an active client device. Consider the situation wherein four users are all stationary, not moving through an urban area. Since each user is stopped, there is no need for other APDs in the urban area to be transmitting. Thus only 4 APDs would be enabled and for receiving and transmitting. Only activating those 4 APDs with clients would reduce power consumption potentially by 83%.
Some example embodiments reduce power consumption by operating each radio in a standby mode, if no client is connected to it.
Some example embodiments reduce power consumption in APDs that have two radios, e.g., a 5 GHz radio and a 2.4 GHz radio, wherein the one of the radios, e.g., the 5 GHz radio, is shut off if no client is connected to it. Almost all mobile devices that support 5 GHz channels also support 2.4 GHz channels. Therefore, it is possible to enable only the 2.4 GHz APD radio, and when a client device connects to the 2.4 GHz radio, the APD will determine whether the client device also supports 5 GHz. If the client device does, then the 5 GHZ radio may be switched on, and the client device is steered (moved) from the 2.4 GHz radio over to the 5 GHz radio. The action of shutting off the 5 GHz radio until it is needed will reduce power consumption by as much as 50% per APD.
Should the user of a client device start to walk through the city, only those APDs in the immediate vicinity would be turned on. As will be described in greater detail below, only those APDs with which the user currently resides, or will potentially travel into, will be activated.
In some embodiments, each APD is in contact with a service provider, which may take the form of a server that operates as an electronic communication traffic server device, which may log the location of each client device, and determining the path the user is expected to travel. With this location and expected travel path information, the electronic communication traffic service device may notify other APDs to turn on and connect to the client device of the user, as needed.
In some embodiments, a cellular service provider that provides cellular service to a client device may determine the location and velocity of the client device. The cellular service provider may provide the location and velocity information to the electronic communication traffic server device, which may log the location of each client device and determine the path the user is expected to travel. With this location and expected travel path information, the electronic communication traffic service device may notify other APDs to turn on and connect to the client device of the user, as needed.
As the user of the client device begins to move through the city, other APDs may be activated by the electronic communication traffic service device. The electronic communication traffic service device would proactively activate APDs in the user’s direction of travel. Likewise, the electronic communication traffic service device would shut off APDs that are no longer needed, or place them in a standby mode. In some embodiments, each activated APD may send positioning information for each client device back to the electronic communication traffic service device.
An example system and method for managing a network of APDs in order to reduce power consumption in accordance with aspects of the present disclosure will now be described in greater detail with reference to
As shown in the figure, method 400 starts (S402), and it is determined whether an activation signal is received (S404). Initially, consider an initial situation wherein 4 client devices are within a portion of a city. This will be described in greater detail with reference to
As shown in the figure, city 100 includes: plurality of eastbound-westbound streets, the sample of which are indicated as streets 102, 104, 106 and 108; plurality of northbound-southbound streets, the sample of which are indicated as streets 110 and 112; plurality of client devices 114, 116, 118 and 120; a plurality of APDs, a sample of which is indicated as APDs A02, A04, A06, A08, A10, A12, A14, A16, A18, A20, A22, A24, A26, A28, A30, A32, A34; a service provider 536 providing a service indicated as double arrow 538; a cellular service provider 540 providing a cellular service indicated as double arrow 542; and a plurality of Wi-Fi hotspot networks provided by the plurality of APDs, respectively, a sample of the plurality of Wi-Fi hotspot networks is indicated as a Wi-Fi hotspot network N44, which is provided by APD A02, a Wi-Fi hotspot network N46, which is provided by APD A04, a Wi-Fi hotspot network N48, which is provided by APD A06, a Wi-Fi hotspot network N50, which is provided by APD A08, a Wi-Fi hotspot network N52, which is provided by APD A10, a Wi-Fi hotspot network N54, which is provided by APD A12, a Wi-Fi hotspot network N56, which is provided by APD A14, a Wi-Fi hotspot network N58, which is provided by APD A20, a Wi-Fi hotspot network N60, which is provided by APD A22, a Wi-Fi hotspot network N62, which is provided by APD A28, a Wi-Fi hotspot network N64, which is provided by APD A30, a Wi-Fi hotspot network N66, which is provided by APD A32, and a Wi-Fi hotspot network N68, which is provided by APD A34.
In accordance with aspects of the present disclosure, each APD is only providing a Wi-Fi network for any specific client device within its broadcasting range, or as directed by service provider 536 through service 538. This is in direct comparison with the conventional system discussed above with reference to
At time t1, discussed above with reference to
In this example embodiment, for the purposes of discussion, let each APD be configured to broadcast eight (8) different SSIDs, wherein each of the broadcasts would provide one eighth (⅛) of the total power that may be expended in broadcasting. Therefore a maximum power expenditure, pmax, would be equal to the total number of APDs, n, times the total number of available broadcast SSIDs, b, or:
which in this example would be Pmax = 24*8 = 192 power units.
It should be noted that is the power that is constantly consumed by the conventional system discussed above with reference to
However, in accordance with aspects of the present disclosure, at time t1, as discussed above, the present power expenditure, pp, would be equal to the sum of the SSIDs from the APDs that are presently broadcasting. In this example, APDs A02, A06, A08, A14, A22, A28, A30, A32 and A34 are broadcasting a single SSID, and APDs A04, A10, A12 and A20 are broadcasting two SSIDs. Therefore, the present power expenditure, pp, at time t1 would be 9*(1) + 4*(2), or 17 power units.
By comparing the power that is constantly consumed by the conventional system discussed above with reference to
Different embodiments for a standby mode will first be described with additional reference to
One embodiment for implementing a standby mode, may be termed a no-broadcast standby mode, wherein a broadcasting component of a radio of an APD will not broadcast until the receiver component of the radio receives either an initiate signal from the service provider or a probe request from a client device. This no-broadcast standby mode will be described with reference to

In the alternative, the processor and the tangible computer-readable media may reside as discrete components.
Example tangible computer-readable media may also be coupled to systems, non-limiting examples of which include a computer system/server, which is operational with numerous other general purpose or special purpose computing system environments or configurations.

Such a computer system/server may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Further, such a computer system/server may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

The OSI model includes seven independent protocol layers: (1) Layer 1, the physical layer, which defines electrical and physical specifications for devices, and the relationship between a device and a transmission medium, such as a copper or fiber optical cable; (2) Layer 2, the data link layer, which provides the functional and procedural means for the transfer of data between network entities and the detection and correction of errors that may occur in the physical layer; (3) Layer 3, the network layer, which provides the functional and procedural means for transferring variable length data sequences from a source host on one network to a destination host on a different network (in contrast to the data link layer which connects hosts within the same network), and performs network routing functions and sometimes fragmentation and reassembly; (4) Layer 4, the transport layer, which provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers by controlling the reliability of a given link through flow control, segmentation/desegmentation, and error control; (5) Layer 5, the session layer, which controls the connections (interchanges) between computers, establishing, managing and terminating the connections between the local and remote applications; (6) Layer 6, the presentation layer, which establishes context between application layer entities, by which the higher-layer entities may use different syntax and semantics when the presentation service provides a mapping between them; and (7) Layer 7, the application layer, which interacts directly with the software applications that implement the communicating component.
Generic Stream Encapsulation (GSE) provides a data link layer protocol, which facilitates the transmission of data from packet oriented protocols (e.g., Internet protocol or IP) on top of a unidirectional physical layer protocol (e.g., DVB-S2, DVB-T2 and DVB-C2). GSE provides functions/characteristics, such as support for multi-protocol encapsulation (e.g., IPv4, IPv6, MPEG, ATM, Ethernet, VLANs, etc.), transparency to network layer functions (e.g., IP encryption and IP header compression), and support of several addressing modes, a mechanism for fragmenting IP datagrams or other network layer packets over baseband frames, and support for hardware and software filtering.
In a layered system, a unit of data that is specified in a protocol of a given layer (e.g., a “packet” at the network layer), and which includes protocol-control information and possibly user data of that layer, is commonly referred to as a “protocol data unit” or PDU. At the network layer, data is formatted into data packets (e.g., IP datagrams, Ethernet Frames, or other network layer packets).
In this example, broadcasting component 614 and receiving component 616 are illustrated as individual devices. However, in some embodiments, broadcasting component 614 and receiving component 616 may be combined as a unitary device.

Upon receiving this request, controller 222 of client device 120 may determine its position and velocity by any known system or method, non-limiting examples of which include a global positioning system or a Wi-Fi triangulation system. Controller 222 may then instruct radio 228 to transmit a client device position signal which includes information describing the position and velocity of client device 120.

In some non-limiting example embodiments, the standby signal will instruct an APD to stop providing the Wi-Fi hotspot network with an SSID identified in the standby signal. In some non-limiting example embodiments, the standby signal will instruct an APD to immediately stop providing the Wi-Fi hotspot network. In other non-limiting example embodiments, the standby signal will instruct an APD to stop providing the Wi-Fi hotspot network after a predetermined time period, for example, after 10 seconds. In other non-limiting example embodiments, the standby signal will instruct an APD to stop providing the Wi-Fi hotspot network after occurrence of an event.

In this example embodiment, for the purposes of discussion, again let the maximum power expenditure, pmax, be that as discussed above with reference to equation (1), which in this example would be Pmax = 24*8 = 192 power units.
However, in accordance with aspects of the present disclosure, at time t2, as discussed above, the present power expenditure, pp, would be equal to the sum of the SSIDs from the APDs that are presently broadcasting. In this example, APDs A02, A04, A06, A08, A14, A16, A18, A20, A22, A24, A26, A28, A30, A32 and A34 are broadcasting a single SSID, and APDs A10 and A12 are broadcasting two SSIDs. Therefore, the present power expenditure, pp, at time t2 would be 15*(1) + 2*(2), or 19 power units.

If it is determined that a new probe request is not received (N at S422), then method 400 continues to wait for a standby signal (return to S414).
If it is determined that a new activation signal has been received (Y at S420) or if it is determined that a new probe request has been received (Y at S422), then a new network is established (S424). This operation may be performed in a manner similar to that discussed above (S408). The difference here (S424) is that an APD is establishing a new Wi-Fi hotspot network using new SSID that is identified in the newly received activation signal (S420) or the newly received probe request (S422) as compared with the original SSID that is currently enabled.
An example of an APD establishing a new Wi-Fi hotspot network using a new SSID that is identified in a newly received activation signal is APD A26 establishing Wi-Fi hotspot network N76 as shown in
