The Challenge with Current AMI Systems
The Grid IQ AMI P2MP Solution Approach
Radio Frequency (RF) Mesh and Power Line Carrier (PLC)Networks have been
the most widely deployed network architectures for AMI. However, when
looking to achieve cost effective, reliable coverage across dense, rural and
sparse suburban environments, Grid IQ AMI P2MP is the optimal solution.
The Grid IQ AMI P2MP Solution is a Point-to-Multipoint or RF “Star”
architecture with numerous coverage and throughput benefits ideal for the
RF propagation environments from rural to urban. Further, the Network is
more than an AMI solution. It is built to support various Grid Modernization
applications beyond Smart Metering.
RF Mesh offers a cost performance that is best deployed in dense suburban
environments. As urban densities increase and suburban densities decrease,
the total cost per meter increases drastically for an RF Mesh enabled meter.
This is because the network requires the addition of multiple routers and
collectors to relay signals through the neighborhood area network as
densities decrease.
PLC systems perform most cost effectively in deployments with high meterto-transformer ratios. For PLC systems the total cost per meter increases
drastically as the ratio of meters-to-transformers decreases, and the
infrastructure costs and operational cost per meter can increase by as
much as 10 times to achieve the necessary coverage requirements in rural
environment.
Remote “Endpoint“ devices, such as utility smart meters or fault indicators,
communicate directly with the “Access Points” deployed either on towers
or utility poles allowing for flexible low cost deployments. An Endpoint a
is device containing a small RF module designed for easy integration and
ultra-low power operation in Smart Meters or sensors. A network of Access
Points can provide redundant coverage for a wide area, such as a city or a
county and has industry leading range enabling ubiquitous coverage. The
Access Point is designed for indoor or outdoor operation and can be easily
deployed on buildings, utility poles or communication towers enabling low
cost pervasive coverage in the most challenging environments.
SMOS (Smart Metering Operations Suite) provides visibility to data retrieved
from network management services, a network of Access Points and
devices. SMOS also provides the back-office integration functions that
deliver data from across the network to core operational systems, such
as Outage Management Systems and other applications. SMOS supports
various industry standard interfaces and protocols.

Purpose Built for Grid Modernization
The Grid IQ AMI P2MP Solution is purpose-built for device monitoring. It
is designed to connect sensor data from a large number of devices to a
network infrastructure that collects data for processing in various backend applications. While the system favors uplink transmissions (device to
network), it also features advanced downlink (network to device) unicast,
multicast, and broadcast features. For example, The Grid IQ AMI P2MP
Solution allows for the broadcast of large firmware upgrades, either for the
device or for the wireless module.
In addition, the system meets or exceeds Grid Modernization communication
requirements, including those recommended by the United States National
Institute of Standards and Technology (NIST). These requirements include
specific security guarantees, reliable data delivery, redundancy, availability,
remote upgradeability, logging, event alarms, a greater-than 20 year
battery life for certain applications, and complete network management
capabilities.
Extensive Coverage and Capacity
The Grid IQ AMI P2MP Solution has exceptional coverage and supports
multiple applications on the same network. This single network features
pervasive coverage for metering and distribution grid monitoring and
sensing regardless of whether the devices are battery operated or powered.
Each access point in the system system supports thousands of connected
devices providing unicast, downlink multicast and broadcast capabilities
and supports group configuration and control. The ability to leverage
a common network infrastructure for multiple applications provides
immediate and significant ROI.
Broad Application Range
The Grid IQ AMI P2MP Solution supports smart metering and is being
deployed today to enable secure, reliable, and robust coverage to battery
operated and powered distribution monitoring devices. The P2MP solution
is suitable for devices deployed in challenging utility environments including
pad mount switches and transformers, battery powered applications, below
ground locations and overhead distribution circuits.
Seamless Scalability and Growth
It is imperative that any Grid Modernization application be cost effective.
The Grid IQ AMI P2MP Solution supports the scalability required to service
multiple grid assets and redundancy with seamless failover. The Grid IQ
AMI Solution accomplishes this through the simple addition of end-point
nodes (meters or sensors) within the network as well as the ability to add
Access Points into the network to achieve the desired functional capabilities.
The Grid IQ AMI P2MP Solution architecture easily adds capacity without
interruption to the existing network operation.

Access Point
End-to-End Security by Design
The Grid IQ AMI P2MP Solution Access Point (AP)
is the key network infrastructure component of
Grid Modernization Infrastructure network. The
AP provides wireless coverage for thousands
of sensor endpoints delivering unmatched
network scalability over vast geographic areas. The AP communicates in
a simple star topology with endpoints in the coverage area. Multiple APs
can be configured to provide extensive coverage. APs communicate with
back-office systems using secure IP networking. On the back-end, the APs
connect to the Gateway.
An effective way to develop a highly secure system is to start from the
ground up with cyber security needs in mind. Security mechanisms cannot
be implemented as “bolt on”. Security must be built into the design to be
most effective. The Grid Modernization Infrastructure network leverages
the broad capabilities of GE by looking across various industries such as
Internet and Telecom, where security techniques are mature, to utilizing
best practices for mutual authentication (valid endpoints will join valid
networks), application message integrity and replay protection, data packet
confidentiality, limited anonymity, and authentic firmware upgrade. Taking
this into account a comprehensive approach to information security was
designed into the system with:
GE’s I-210 or SGM3000 Meter and Meter
Communications Module
• Prevention mechanisms to provide access control, integrity protection,
confidentiality, and availability.
The Electric MCM is integrated with both the
I-210 ANSI and SGM3000 IEC Family of meters
and provides:
• Recovery mechanisms to ensure system continues to operate as desired
and degrades gracefully.
• Detection mechanisms to detect attempts to break into the system.
• Up to fifteen minute intervals and daily
register reads provided every fifteen minutes
over the network, including precise event
correlation across reads.
Well recognized and time-tested security mechanisms are required to
achieve these goals. The following security mechanisms are implemented
and are best suited for a network that is a point-to-multipoint topology,
bandwidth efficient and power maximizing:
• Two-way meter communication to support on demand functionality,
meter configuration, and remote meter disconnect.
• Symmetric key algorithms
• Last gasp meter reporting for power outage.
• CMAC (AES 128-bit) for Over-the-Air (OTA) message integrity and node
authentication
• Over the air updates of endpoint firmware.
• End-to-end security designed for Grid Modernization applications
to ensure meter to network authentication, message integrity and
confidentiality, and secure firmware binary updates.
• AAA key management server with diameter protocol
• 3-key TDES (192-bit) for link layer confidentiality and AES-128 bit
encryption for application data confidentiality
• No OTA key exchange
• SSL encryption for back-end IP infrastructure
GE’s MDS WiYZ™ Remote
• Authentic firmware upgrade
MDS WiYZ Remotes are packed with features and
functionality to match up with a diverse range of remote
monitoring and control requirements. Each Remote
accommodates 2 Analog Inputs, 2 Analog Outputs, 2
Digital Inputs and 2 Digital Outputs. One RS232 port is
used for configuration.Optional radio configuration to
operate on the Grid IQ AMI P2MP network.
