“Advanced metering infrastructure (AMI) is
the
bedrock

of the smart grid.”

“…AMI technology provides
a foundation

for the
achievement of smart grid benefits.”

The World on the Shoulders of AMI…

Are These Reasonable Expectations ?

Regulators and utilities will expect the
communications foundation for a smart grid
to deliver more and therefore to cost more.

Application Value Supports the Cost


Residential meters need not be $20 devices


HAN gateways, integrated disconnect switches, outage
ride
-
through, etc


all driving up the cost / value curve


Transceiver chipset not seen as driving the overall
BOM cost. Do not compromise performance for
pennies.

Utility Benefits from a Common Phy/Mac



Improving performance


dedicated IC’s outperforming
multipurpose devices


Hardware that can be remotely switched from vendor A
network to vendor B network


Decoupling networking technology from manufacturing
-

enabling AMI companies that don’t produce hardware


A platform upon which additional standards could be
built


potential for eventual multivendor interoperability

Target RFP Language: “All system equipment must
have at least two independent sources of supply.”

A Window of Opportunity

Many utility needs are immediate, others
emerging


Utilities are being tempted by costly
alternatives that are not technically ideal



“Consensus” more beneficial than “best”
