A local area network may serve as few as two or three users in a home office or thousands of users in a corporation's central office.
What is a Wide Area Network?
A wide area network (also known as WAN), is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.
What is field area network?
The field area network (FAN) is arguably the most complex piece of the communications network, since it is primarily responsible for providing “last-mile” communications to end-devices.
What is the use of personal area network?
A personal area network (PAN) connects electronic devices within a user's immediate area. The size of a PAN ranges from a few centimeters to a few meters. One of the most common real-world examples of a PAN is the connection between a Bluetooth earpiece and a smartphone.
What is a NAN?
A near-me area network ( NAN) is a communication network that focuses on wireless communication among devices in close proximity. Unlike local area networks (LANs), where the devices are in the same network segment and share the same broadcast domain, the devices in a NAN can belong to different proprietary network infrastructures (for example, ...
What is NAN in mobile phone?
Due to the increasing popularity of location-enabled (or GPS -enabled) mobile devices (including iPhone and Android phones), the near-me area network (NAN) is currently being used as a means of wireless communication for areas which do not require the full coverage of a local area network.
What is a wide area network?
Wide area networks provide communication in a broad geographic area covering national and international locations. Personal area networks (PANs) are wireless LANs with a very short range (up to a few meters), enabling computer device (such as PDAs and printers) to communicate with other nearby devices and computers.
What is a SG NAN?
SG NAN and Field Area Network (FAN ) applications that are AMI or smart meter based are typically semi-periodic. For example, AMR, DM, electric vehicle (EV) charging and discharging and micro-grid management. DR is responsible for load balancing between the power generator and consumers by utilizing load control programs. The load control could be based on dynamic energy unit pricing or based on a more advanced technique like remote load control (RLC). Examples of well know dynamic price programs are time-of-use (TOU), real-time pricing (RTP), critical peak pricing (CPP) and peak time rebates (PTR). The characteristics of an RLC program can vary based on properties such as interruptible loads, reducible loads, partially interruptible loads. More details on the DR programs could be found in [ 25 ]. Distribution automation (DA) [ 26] should be designed for near real-time information about the grid operation and is used to improve distribution network monitoring and control by utilizing power distribution control, monitoring and management devices such as voltage regulators, fault detectors, capacitor bank controllers, and reclosers. A DA system can enable useful applications like Volt/VAR control, fault detection, isolation and restoration and distribution system monitoring and maintenance. Volt/VAR control adjusts the voltage and balances the load factor to reduce energy loss. In distribution monitoring and maintenance, sensor data is used to monitor the status (open/closed) of various distribution network equipment. With fault detection isolation and restoration, a section of the grid could be isolated if there is an occurrence of a fault and automatic restoration systems can be used to minimize the service interruption.
What is emerging SG?
The emerging SGs and SG applications is providing the motivation needed to upgrade SG communication networks. In this paper, a novel approach for handling the SG applications within a NAN domain is proposed based on the SDN paradigm. The proposed framework focuses on SDN based SG NANs and is advantageous because of the flexibility and programmability provided by SDN and its ability to manage a large number of M2M devices. The paper sheds light on the crucial challenge of finding the number of controllers required for a WSN based NAN domain. The mathematical model presented was developed based on WSNs using the cc2350 standard. Deployments of proactive and reactive SG applications eliminate the difficulty of managing the delay sensitive and delay tolerant applications. The approach used to determine the number of controllers needed in a NAN with WSN connected devices provides a means to ensure that overdesigning and overprovisioning controllers does not occur. The continuation of this work will include implementing the framework using a testbed. Cross-domain communication in SGs utilizing SDN multi-controller communications remains another area for further investigation.

What is a NAN?
The NAN is the last mile network infrastructure connecting the AMI, DA, and Remote Workforce management devices to the field area routers. The devices include smart meters, electric vehicles, feeder meters, transformer meters, and NAN repeaters. They may be directly attached to a CGR 1000 series router interface such as Ethernet, Serial, or Wi-Fi or may be reachable through an IEEE 802.15.4g/e RF or IEEE 1901.2a PLC Mesh subnet. This infrastructure enables measurement of electricity consumed and produced by prosumers and also provides the foundation for advanced applications like demand response (DR), which provides the opportunity to optimize energy usage during peak periods, and Distribution Automation (DA), which allows distribution monitoring and control. The FARs provide an interface to the WAN backhaul to facilitate communication with the head-end systems.
What is a FAR network?
The Field Area Router (FAR) acts as a network gateway for Connected Grid End-points, by forwarding data from the meters to the head-end systems. It is a critical element of the architecture as it ties the NAN and the WAN tier together.
What is the network operations center?
The Network Operations Center (NOC) is referred to as the Energy Operations Center (EOC) in the context of utilities. The Energy Operations Center hosts all applications necessary to operate, manage, and secure the FAN sites and equipment. It is typically located in the Utility facility and may in some cases be co-located with the Utility Data Center. In a multi-service FAN deployment, the EOC will host the applications and associated servers performing the tasks required by AMI, DA, Remote Asset Management, and Remote Workforce Management.
Is WAN backhaul private or public?
This may be a private or public network, either owned by the utility itself or outsourced to a service provider. Popular WAN backhaul options are Ethernet, Fiber, WiMAX, and Cellular 3G/4G. Other backhaul types for FARs may be a public or private IEEE 802.11 Wi-Fi smart cities infrastructure or satellite.
