BACKGROUND
This invention relates generally to methods and systems for transmitting utility data to a utility provider. More specifically the invention relates methods and systems for transmitting utility data using a broadband modem and a service provider's access network.
Traditional utility meter reading has involved a utility company sending a technician out to a customer premises to visually read the utility meter. Radio frequency technology has made the process somewhat easier by allowing a technician to drive through a neighborhood with a radio receiver and gather utility meter readings that are transmitted over a radio frequency from the utility meter to the technician's receiver. Both of these techniques require substantial human interaction, resulting in increased cost and decreased convenience. Moreover, neither of these methods is amenable to real-time meter reading.
At the same time, technologies have developed to allow utility customers to monitor and manage different devices and appliances within their homes. However, these technologies currently are limited to individual users implementing their own Home Automated Networks using private Home Networking mechanisms such as X10, Z-Wave, and Zigbee. To date, however, such technologies have been implemented on an individual scale and cannot benefit from centralized monitoring and/or management capabilities; further, because there is no interface between such technologies and current information about utility rates, the potential benefits of such technologies have not been maximized.
There is thus a need for tools and techniques that allow utility providers to collect meter readings without a technician having to visit a customer premises. It would be advantageous, in some situations, for such tools and techniques to provide centralized monitoring, managing, and controlling of device usage in the home.
BRIEF SUMMARY
Certain embodiments thus provide tools and techniques allowing utility providers to collect meter readings without a technician having to visit a customer premises, along with providing centralized monitoring, managing, and control of device usage in a home. Data pertaining to a meter reading may be transmitted from a utility meter to an access point of a public broadband network, in some cases without any human intervention. The access point may include a modem, such as a digital subscriber line (“DSL”) modem (to name but one example), which may modulate the data pertaining to the meter reading. The modulated data may then be transmitted securely through a public switched telephone network (“PSTN”) to the Internet. The data may then be received by the utility provider via the Internet.
Some embodiments may take advantage of existing equipment, networks, infrastructures, and devices. Merely by way of example, some embodiments may utilize an existing or easily installed access point, such as a DSL modem at a customer premises. In addition, some embodiments may utilize an existing public network, including without limitation a broadband network and/or a public switched telephone network, rather than requiring the deployment of additional communication mediums. Embodiments may also utilize wireless technology that presently allow technicians to capture meter reading data with a handheld device. This existing wireless technology may provide a communication link for data to be transmitted through a service provider's access network to a utility provider without human intervention.
Certain embodiments are directed to methods and systems for transmitting utility usage data using a public switched telephone network. The methods and systems may include collecting utility usage data pertaining to a customer premises with a utility meter at the customer premises. The utility usage data may be transmitted automatically from the utility meter to an access point of a public broadband network. The utility usage data may be received at the access point. A digital subscriber line modem in communication with the access point may modulate the utility usage data at the access point. The utility usage data may be transmitted securely through the public switched telephone network to an Internet point of presence. The utility usage data may be received at the Internet point of presence. The utility usage data may be transmitted from the Internet point of presence to a utility provider via the Internet. In some cases, a virtual private network may be used to transmit the utility usage data; in other cases, a private line may be used to transmit the utility usage data, e.g., from a local office of a telecommunication provider to the utility provider.
Embodiments may include methods and systems for transmitting utility usage data using a service provider's access network. Methods and systems may include collecting utility usage data with a data collecting device. The utility usage data may be transmitted from the data collecting device to an access point coupled with a modem. The utility usage data may be received at the access point. The utility usage day may be transmitted from the access point to a receiving entity through the service provider's access network.
In another embodiment, a system may transmit utility usage data using a public switched telephone network. The system may include a power line communications network at a customer premises. A utility meter may be in communication with a power line communications network. The utility meter may collect utility usage data from the customer premises. A transmission device may be in communication with the utility meter. The transmission device may be configured to transmit automatically and securely utility usage data from the utility meter. An access device may be in communication with the transmission device to receive the secure utility usage data. A digital subscriber line modem may be in communication with the access device. The DSL modem may be configured to securely transmit the utility usage data through a public switched telephone network to a utility provider via the Internet.
In yet another embodiment, a system for transmitting utility usage data over a service provider's access network is provided. The system may include a utility usage data collecting device. The system may also include a broadband modem in communication with the utility usage data collecting device. The broadband modem may be configured to communicate with the service provider's access network and/or to transmit utility usage data from the utility usage data collecting device to a receiving entity.

Certain embodiments are directed to methods and systems for transmitting utility usage data using a public switched telephone network (“PSTN”). PSTN may include local loops or subscriber lines that may be physical links or circuits that connect from a demarcation point of a customer premises to a service provider's network. A local loop may be provisioned to support data communications applications. A local loop may be provisioned to support combined voice and data such as a digital subscriber line (“DSL”). The methods and systems may include collecting utility usage data pertaining to a customer premises with a utility meter at the customer premises. The utility usage data may be transmitted automatically from the utility meter to an access point of a public broadband network. The utility usage data may be received at the access point. A DSL modem in communication with the access point may modulate the utility usage data at the access point. The utility usage data may be transmitted securely through the public switched telephone network to an Internet point of presence. The utility usage data may be received at the Internet point of presence. The utility usage data may be transmitted from the Internet point of presence to a utility provider via the Internet, via a virtual private network (“VPN”), and/or via a private line, among other possibilities.
Embodiments may include methods and systems for transmitting utility usage data using a service provider's access network. Methods and systems may include collecting utility usage data with a data collecting device. The utility usage data may be transmitted from the data collecting device to an access point coupled with a modem. The utility usage data may be received at the access point. The utility usage data may be transmitted from the access point to a receiving entity through the service provider's access network.
A data collecting device may include a wide variety of devices, including without limitation a utility meter, such as an electricity meter, a gas meter, and/or a water meter. A utility meter may collect data regarding customer premises equipment (“CPE”). A utility meter may collect data regarding smart devices. Merely by way of example, smart devices may include any devices, outlets, appliances, and/or equipment that may be capable to sending or receiving information in order to facilitate monitoring, maintaining, and/or controlling the smart device. A data collecting device may include, but not limited to, such things as a set-top box or a network interface device. A data collecting device may include a computer, capable of gathering, storing, and/or transmitting data regarding utility usage. In some cases, a data collecting device may be a dedicated device for collecting utility usage data from a variety of devices within a particular premises; such a device may be (but need not necessarily be) incorporated within and/or in communication with a utility meter.
A data collecting device may be in communication with a power line communications (“PLC”) network. A PLC network may include any system in which data is transmitted over power lines, which may include without limitation relatively high-voltage transmission lines, medium voltage distribution lines, and lower voltage lines used inside buildings. PLC may include, inter alia, systems referred to in the art as power line carrier, power line digital subscriber line, mains communication, power line telecom, and/or power line networking. PLC may be a system for carrying data on a conductor also used for electric power transmission. PLC may include impressing a modulated carrier signal on a wiring system to convey information along the wiring system. In some embodiments, a PLC network may provide Internet access to devices connected to the PLC network. A PLC network may also be used to query and send commands to smart devices, enabling them to be remotely monitored, controlled, and/or maintained by servers in a network. A user of the smart devices may also be able to monitor, control, and/or maintain different devices using a PLC network. A PLC network may also comprise and/or be bridged to a Home Network. This may effectively expand the Home Network to include data capabilities over the AC power lines in a customer premises.
A data collecting device may be attached to the exterior wall of a customer premises. In some embodiments, a data collecting device may be located within a customer premises or remotely from a customer premises. In some embodiments, a data collecting device may be coupled with an access point. Some embodiments that include a data collecting device coupled with an access point may receive utility usage data using a variety of technologies, including, but not limited, to Encoder Receiver Transmitter (“ERT”) and/or other wireless technologies.
Utility usage data may include a wide variety of data, including without limitation electricity usage data, water usage data, gas usage data, and/or smart device utility usage data. Usage data can include, for example, information about a quantity of electricity, water, gas, etc. used, information about a rate of use, information about a time period of use, and/or the like. In a particular example, a set of utility usage data might specify that a customer premises had consumed a particular volume (or mass) of natural gas over a particular time period (such as 12:00 am to 6:00 am on a particular date). In some embodiments, utility usage data may be transmitted from a single customer premises to a remote terminal, while in other embodiments, utility usage data may be transmitted from multiple customer premises to a remote terminal.
Utility usage data may be transmitted from a data collecting device in many different ways, including without limitation being transmitted automatically without human input. Data may be transmitted on a regular schedule, such as every second, every minute, every hour, every day, and/or every month, or based on specific numerical increments of these time units. Data may be transmitted in real-time. Data may be transmitted based on other factors, such as when the utility usage changes and/or on demand. For example, when the utility usage goes up or goes down and/or when a specific device is used, data may be transmitted in some embodiments. Data may be transmitted when queried by another device, server, entity, and/or user. Data may be transmitted when the cost of utility usage changes. Merely by way of example, if the cost of electricity, gas, and/or water changes, the rate or timing of data transmission may change, which may allow a utility provider to charge more accurately a customer based on when and how they use a utility. Also, the rate or timing of data transmission may also be determined to help provide a user of the utility, such as a utility customer, more information so that they may be better able to monitor, maintain, and/or control their utility usage. Data may also be transmitted when the data collecting device receives a prompt sent by a receiving entity.
An access point may receive utility usage data from a data collecting device. The access point may include a modem, which may modulate the utility usage data so that it may be transmitted over different transport mediums and/or different communications networks and/or infrastructures. In some embodiments, an access point may be integrated into a modem. In some embodiments, an access point may be interfaced to communicate with the modem. A modem may be a broadband modem. In some embodiments, a modem may be a DSL modem. In some embodiments, a modem may be an optical network termination (“ONT”) device. Devices such as a ONT and DSL modem may in general provide a means for connecting to a service provider's access network. These devices in general may be referred to as access network interface devices. An access point may be an access point of a pubic broadband network and/or a service provider's access network. A service provider's access network may include a DSL network in some embodiments. In some embodiments, a service provider's access network may include an optical network, which may include without limitation fiber to the premises (“FTTP”) architectures, fiber to the curb (“FTTC”) architectures, and fiber to the house (“FTTH”) architectures.
An access point may include or be coupled with different devices and/or components. In some embodiments, an access point may include an Ethernet switch and/or a router. Switch/router may have one or more ports. One port may connect with a Home Network. It may do so using any number of Home Networking technologies such as, merely by way of example, Ethernet over CAT5 cabling, MoCA over Coax, HPNA over twisted-pair, PLC over AC wiring, G.hn (currently being standardized in the ITU). Another port may connect with a data collecting device. In some embodiments, a port of the access point may be configured to interface with different types of communication channel specifications. Merely by way of example, an access point may be configured to interface with RS 485, EIA-485, RS 422, and/or encoder-receiver-transmitter (“ERT”), which may be used with different data collecting devices and interface components coupled with a data collecting device in order to transmit data to a receiver.
An access point may include and/or be coupled with a wireless access component and/or point (for example, a “WiFi AP”). (Although the term “WiFi” is used herein for convenience, it should be appreciated that this term includes any appropriate wireless transmission technologies, including without limitation the IEEE 802.11 suite of protocols, as well as WiMax, Bluetooth, Wireless USB, CDMA- and/or GSM-based technologies, and/or the like.) Through a WiFi AP, an access point may receive utility usage data from a data collection device. An access point may also transmit data to data collection device through a WiFi AP. In other embodiments, an access point may be in communication with a data collection device through a physical transmission medium. In some embodiments, an access point may be in communication with a data collection device through an Ethernet and/or USB cable. In some embodiments, power may be transmitted to an access point to power the devices and/or components of the access device and/or coupled with the access device through Power over Ethernet (“PoE”). Some embodiments may include an access point that may receive power in numerous different ways including, but not limited to, line powering over a copper pair and/or power from a power take-off collar from a power meter.
An access point may be located exterior to a customer premises in some embodiments. An access point may be located within a customer premises. In some embodiments, an access point may communicate with numerous data collection devices associated with different customer premises.
In some embodiments, an access point may comprise and/or be incorporated with a network interface device (“NID”). The Incorporated Applications describe various NIDs in detail. Any of such NIDs can be implemented as an access point in accordance with various embodiments. Similarly, the various transport media described in connection with these NIDs may serve as the communication infrastructure implemented by various embodiments described herein.
Utility usage data may be transmitted from an access point to a receiving entity in different ways. Utility usage data may be transmitted through a service provider's access network. Utility usage data may be transmitted through a public switched telephone network. Utility usage data may be received at an Internet point of presence and then reach a receiving entity via the Internet.
Embodiments may include different receiving entities, including the following with a limitation. A receiving entity may include a utility provider. A receiving entity may include a service provider that may provide access to an access network. A receiving entity may be a utility services provider that provides services to utility providers and/or utility customers. A receiving entity may also include a customer and/or user of a utility. A receiving entity may include an aggregation provider. An aggregation provider may receive utility usage data from multiple sources. Merely by way of example, an aggregation provider may aggregate data from multiple sources through a network including, but not limited to, a broadband over power line and/or mesh network and provide the aggregated data to an access point. An aggregation provider may be an intermediate receiving entity that may receive utility usage data before another receiving entity receives the utility usage data.
Transmitting utility usage data from a data collecting device to an access point and then from an access point to a receiving entity may be done securely. In some embodiments, the utility usage data may be encrypted. In some embodiments, utility usage data may be securely transmitted using methods, networks, and or protocols such as SSL, VPN, HTTPS and/or other known methods for securely transmitting data over different communications channels. In some embodiments, utility usage data from a data collection device may include identification information that distinguishes it from other utility usage data from other data collection devices. This may allow different access points and/or receiving entities to know if different data collecting devices have been successfully communicated with, which data collecting data devices have not been communicated with, providing for alternative measures to be taken if necessary.
In some embodiments, methods may include bi-directional communication. Utility usage data, for example, may be transmitted to a receiving entity. Data may be transmitted from a receiving entity or other entity to a data collecting device. A data collecting device in communication with a PLC may send this received data to a device, appliance, or equipment also in communication with the PLC in order to control, monitor, and/or maintain the device, appliance, or equipment.
In some embodiments, a set of control data may be received at an access point from a service provider's access network. The control data may be transmitted from the access point to a data collecting device. The control data may be received at the data collecting device and then transmitted to at least one device in order to control, monitor, and/or maintain the device. (Alternatively, the access point may transmit such data directly to the device to be controlled, monitored and/or maintained.) In some embodiments, the control data received at the data collecting device may prompt the data collecting device to transmit utility usage data to a receiving entity. Merely by way of example, a data collecting device may need to be “woken up” before it will transmit data. Thus, in some embodiments, a receiving entity may transmit to a data collecting device a “wake up” signal, prompting the data collecting device to send data to the receiving entity, for example.
In another embodiment, a system may transmit utility usage data using a PSTN. The system may include a power line communications network at a customer premises. A utility meter may be in communication with a power line communications network. The utility meter may collect utility usage data from the customer premises. A transmission device may be in communication with the utility meter. The transmission device may be configured to transmit automatically and securely utility usage data from the utility meter. An access device may be in communication with the transmission device to receive the secure utility usage data. A DSL modem may be in communication with the access device. The DSL modem may be configured to securely transmit the utility usage data through a PSTN to a utility provider via the Internet.
In another embodiment, a system for transmitting utility usage data over a service provider's access network is provided. The system may include a utility usage data collecting device. The system may also include a broadband modem in communication with the utility usage data collecting device. The broadband modem may be configured to communicate with the service provider's access network and to transmit utility usage data from the utility usage data collecting device to a receiving entity.
The system for transmitting utility usage data over a service provider's access network may include a power line communications (“PLC”) network in communication with the data collecting device in some embodiments. The PLC network may provide communication between devices, appliances, and/or other equipment at a customer premises and the utility usage data collecting device.
The system for transmitting utility usage data over a service provider's access network may include a network interface device (“NID”). The Incorporated Applications describe various NIDs in detail. As noted above, any of such NIDs can be implemented as a remote terminal in accordance with various embodiments. Similarly, the various transport media described in connection with these NIDs may serve as the communication infrastructure implemented by various embodiments described herein. A broadband modem may be housed within the NID device in some embodiments.
In some embodiments, the broadband modem may be configured to receive control instructions from the receiving entity. Control instructions may include instructions for controlling, monitoring, and/or maintaining devices at a customer premises. The broadband modem may be configured to transmit the control instructions to the utility usage data collecting device. The system may be configured to transmit the control instructions through a PLC network to a device, appliance, and/or equipment at a customer premises.
Turning now to FIG. 1, a system 100 for transmitting utility usage data and/or receiving utility control, monitoring, and maintenance data using a service provider's access network is shown. Digital subscriber line (“DSL”) 110 may carry both low frequency analog voice and high frequency data. Splitter 115 may separate the spectrum so that low frequency voice information may go to telephone 120 via phone line 121, and the high frequency data information may go to DSL Modem 125. DSL modem 125 may demodulate the signal and presents it to Ethernet switch/router 130. DSL modem 125 and Ethernet switch/router 130 may be housed together, or separately while still being in communication with each other. These components that provide access to a network may be referred to as access point 190. Access point 190 may be exterior to a customer premises boundary 180. In some embodiments, an access point may have demarcation capabilities. The Incorporated Applications describe various demarcation capabilities in detail.
Switch/router 130 may have one or more ports. One port 132 may connect to a Home Network 135 (e.g., through a bridge 133). It may do so using any number of Home Networking technologies such as, merely by way of example, Ethernet over CAT5 cabling, MoCA over Coax, HPNA over twisted-pair, PLC over AC wiring, and/or G.hn (currently being standardized in the ITU). Another port 138 may connect to data collecting device 140 through another bridge 139. In some embodiments, data collecting device 140 may be a utility meter. A utility meter may include a meter for measuring electricity, water, and/or gas usage. In some embodiments, data collecting device 140 may gather data regarding the use of at least one smart device. Data collecting devices and the data they may gather is discussed in more detail above.
In some embodiments, access point 190 may include modem, such as DSL modem 125, that may be powered from a connection coupled with data collecting device 140 using a variety of technologies. In one embodiment shown in FIG. 1, Power over Ethernet (“POE”) 145 may be used. POE may provide power over an Ethernet cable/USB cable to receiving devices such as the DSL modem 125, switch/router 130, and/or access point 190 in general. Data collecting device 140 may then interface to switch/router 130 and either transmit or receive data as appropriate. Utility usage data may be transmitted over DSL line 110 back to Internet cloud 150. Internet cloud 150 may route utility usage data to server 155 that collects the utility usage data and performs appropriate management activities. Server 155 may belong to a utility provider or it may be a server associated with a service provider's access network. In some embodiments, utility usage data may be routed to a user of the utility. Various servers may perform or enable a variety of services that may or may not be based on the utility usage data indicated by data collecting device 140.
Access point 190 may be coupled with data collecting device 140 and Home Network 135 in numerous additional ways. Access Point 190 may include ports, such as 132 and 138. Merely by way of example, ports 132 and 138 may connect to Home Network 135 and/or data collecting device 140, respectively. It may do so using any number of Home Networking technologies such as, merely by way of example, Ethernet over CAT5 cabling, MoCA over Coax, HPNA over twisted-pair, PLC over AC wiring, and/or G.hn (currently being standardized in the ITU). In some embodiments, ports of access point 190 may be configured to interface with different types of communication channel specifications. Merely by way of example, access point 190 and/or its ports, such as 138, may be configured to interface with RS 485, EIA-485, RS 422, and/or encoder-receiver-transmitter (“ERT”), which may be used with different data collecting devices and interface components coupled with data collecting device 140 in order to transmit data to a receiver.
In some embodiments, data collecting device 140 may interface with Power Line Communications (“PLC”) network 160 to either provide access to the Internet 150 to devices connected to PLC network 160 and/or to query and/or send commands to intelligent appliances at a customer premises enabling them to be remotely monitored, controlled, and/or maintained by server(s) 155 in the network. PLC network 160 may also be bridged 175 to Home Network 135 effectively expanding Home Network 135 to include data capabilities over AC power lines 170. In some embodiments, components of system 100 may fall on different sides of customer premises boundary 180.
FIG. 2 shows another embodiment of system 200 for transmitting utility usage data and/or receiving utility control, monitoring, and maintenance data using a service provider's access network. System 200 may be used in situations where DSL modem 125 may be integrated with a wireless access point, such as WiFi access point (“WiFi AP”) 222 or other wireless technology, forming an overall integrated access device (“IAD”) 220. IAD 220 may also include Ethernet switch/router 130. In some embodiments, DSL modem 125, WiFi AP 222, and/or switch/router 130 may be in communication with each other, but not integrated. In some embodiments, WiFi AP 222 may be separately housed from DSL Modem 125. Access device 220 may be located inside a customer premises. A wireless client, such as WiFi client 245 at data collection device 140, may associate with access device 222 and or WiFi AP 222 and transport data communication to DSL line 110 through access device 222.
In some embodiments, WiFi client 245 may be able to associate with another WiFi AP besides WiFi AP 222. In some cases, WiFi client 245 may be able to associate with numerous other WiFi APs within range of WiFi client 245. WiFi client 245 may be authorized to associate with these other WiFi APs. Consequently, if WiFi AP 222 may be turned off or is not otherwise functioning, WiFi client 245 at data collection device 140 may associate with another WiFi AP to communicate with server(s) 155. Embodiments such as this may create a redundant mesh.
Data collected by the data collecting device 140 and transmitted 250-a/250-b from WiFi client 245 may be encrypted. In some embodiments, data collecting device 140 may encrypt the data. WiFi devices such as 245 and/or 222 may also encrypt data to ensure security. In some embodiments, the ability to partition a bandwidth to utilize excess capacity may be used so that a service level agreement (“SLA”) is not compromised when server(s) 155 are communicating with data collecting device 140 or other Smart Home devices.
Wireless devices and/or components such as 222 and 245 may also employ a store-and-forward capability so that if DSL modem 125 and associated devices are turned off, or there is a power failure, the exchange of data can resume when the power is restored. Wireless devices such as 222 and 245 may also communicate bi-directionally. Merely by way of example, and more thoroughly discussed above and below, WiFi AP 222 may transmit control data 252, such as 252-a and 252-b, received from server(s) 155 to WiFi client 245, where control data may be used to control, monitor, and/or maintain devices in communication with meter 140 through PLC 160, AC power lines 170, and/or Home Network 135.
One skilled in the art will recognize that the wireless communication devices disclosed, such as WiFi AP 222 and WiFi client 245 may employ different wireless transmission technologies and protocols.

From broadband modem 725, utility usage data may be securely transmitted through Internet or private net, using encryption or other security protocols and/methods such as SSL, VPN, and/or HTTPS, merely by way of example. In some embodiments, broadband modem 725 may utilize a service provider's access network to transmit utility usage data to an Internet point of presence. Utility usage data may be transmitted to server 755 (for example, server(s) 155). Server 755 may be a utility collection server. In some embodiments, transmission may be bi-directional, such that may be transmitted from utility meter 740 to server 755, and data and/or instructions may be transmitted from server 755 to utility meter 740. These transmissions may be used to control, monitor, or maintain devices associated and/or in further communication with utility meter 740. For example, utility meter 740 may be in communication with a power line communications network (for example, PLC 160).
FIG. 8 shows another embodiment of a system 800 for transmitting utility usage data and/or receiving utility control, monitoring, and maintenance data using a service provider's access network. System 800 includes utility monitoring module (“UMM”) 810. UMM 810 may be used to monitor utility usage for a single customer premises or multiple premises. UMM 810 may receive utility usage data from utility box(es) 840A-N (for example, data collecting device 140). Utility boxes 840A-N may be in communication with wireless modules 845A-N (for example, WiFi client 245), respectively, in order to transmit utility usage data to a receiver, such as a receiver used by a utility company that gathers data by sending a technician through a neighborhood to gather utility meter readings. In one embodiment, UMM 810 receives utility usage data from utility boxes 840A-N and may then transmit it to another device capable of connecting to a network, such as Internet 150. UMM 810 may transmit utility usage data to broadband modem 825 (for example, modem 125), which may then transmit modulated utility usage data to server 855 (for example, server(s) 155) via Internet 150. In some embodiments, UMM 81 may transmit utility usage data to network interface device (“NID”) 835, which may also transmit utility usage data to server 855 via Internet 150.
UMM 810 may be coupled with utility box 840 in some embodiments. In other embodiments, UMM 810 may be coupled with broadband modem 825 or NID 835 via an Ethernet/USB cable. In still other embodiments, UMM 810 may be built into modem 825 or NID 835.
In some embodiments, UMM 810 may be provided for each utility and/or service provider. Thus, there may be multiple UMMs associated with a customer premises. In other embodiments, UMM 810 may be a central UMM, capable of aggregating utility usage data from multiple types of utility use associated possible with different utility providers.
In some embodiments, UMM 810 may do more than receive data from utility boxes like 840. UMM 810 may be capable of transmitting data and/or instructions to utility box 840. UMM 810 may, for example, transmit control data received from utility collection/controller server 855, through either broadband modem 825 or NID 835, to utility box 840. Control data may be used to control, monitor, or maintain devices in communication with utility box 840. In some embodiments, this may be achieved through a power line communications network in communication with utility box 840.
As similarly discussed with other embodiments, UMM 810 may also facilitate how frequently utility usage data is transmitted through the system. Data may be transmitted automatically without human input. Data may be transmitted on a regular schedule, such as every second, every minute, every hour, every day, and/or every month, or based on specific numerical increments of these time units. Data may be transmitted in real-time. Data may be transmitted based on other factors, such as when the utility usage changes, such as when the utility usage goes up or goes down and/or when a specific device is used. Data may be transmitted when queried by another device, server, entity, and/or user. Data may be transmitted when the cost of utility usage changes. Merely by way of example, if the cost of electricity, gas, and/or water changes, the rate or timing of data transmission may change, which may allow a utility provider to charge more accurately a customer based on when and how to use a utility. Also, the rate or timing of data transmission may also be determined to help provide a user of the utility, such as a utility customer, more information so that they may be better able to monitor and control their utility usage. Data may also be transmitted when the data collecting device receives a prompt sent by a receiving entity.
As similarly discussed with other embodiments, UMM 810 may transmit utility usage data securely using methods disclosed above, for example.
FIG. 9 illustrates a method 900 of transmitting utility usage data. Method 900 may be employed on systems such as system 100, 200, 300, 400, 500, 600, 700, and/or 800.

Method 900 may include receiving the utility usage data at the access point (including without limitation any of the access points described above) from a data collecting device (block 930).
Method 900 may include transmitting the utility usage data from the access point to a receiving entity (described above) through the service provider's access network (block 940). Utility usage data may be transmitted from an access point to a receiving entity in a variety of different ways, including without limitation transmission through a service provider's access network. Utility usage data may be transmitted through a public switched telephone network. Utility usage data may be received at an Internet point of presence and the reach a receiving entity via the Internet.
As noted above, data may be transmitted securely from a data collecting device to an access point and/or from an access point to a receiving entity. Merely by way of example, in some embodiments, the utility usage data may be encrypted. In some embodiments, utility usage data may be securely transmitted using methods, networks, and/or protocols such as SSL, VPN, HTTPS and/or other known methods for securely transmitting data over different communications channels. In some embodiments, utility usage data from a data collection device may include identification information that distinguishes it from other utility usage data from other data collection devices. This may allow different access points and/or receiving entities to know if different data collecting devices have been successfully communicated with, which data collecting data devices have not been communicated with, providing for alternative measures to be taken if necessary.
FIG. 10 illustrates a method 1000 of transmitting utility usage data utilizing the other systems and methods disclosed above that also include control data. Method 1000 may be employed on systems such as those disclosed above. In some embodiments, method 1000 may include bi-directional communication. Utility usage data, for example, may be transmitted to a receiving entity as disclosed above, for example, with respect to method 900. Data may also be transmitted from a receiving entity or other entity to a data collecting device. A data collecting device in communication with a PLC may send this received data to a device, appliance, or equipment also in communication with the PLC in order to control, monitor, and/or maintain the device, appliance, or equipment.
In one embodiment, method 1000 may include receiving a set of control data at an access point (block 1010). Method 1000 comprises transmitting the control data from the access point to a data collecting device (block 1020). Method 1000 may include receiving the control data at the data collecting device (block 1030). The control data may be transmitted from the access point to a data collecting device. Method 1000 may include transmitting the control data from the data collecting device to at least one device (block 1040). Method 1000 may include controlling the at least one device with the control data (block 1050). The control data may be received at the data collecting device and then transmitted to multiple devices order to control, monitor, and/or maintain the device (block 1060). In some embodiments, the control data received at the data collecting device may prompt the data collecting device to transmit utility usage data to a receiving entity. Merely by way of example, a data collecting device may need to be “woken up” before it will transmit data. Thus, in some embodiments, a receiving entity may transmit to a data collecting device a “wake up” signal, prompting the data collecting device to send data to the receiving entity, for example. The systems and methods disclosed throughout this application provide further aspects that may be employed within embodiments of method 1000.
