6. TG4g - SUN May 2009 Brian K. Seal, Electric Power Research Institute doc.: IEEE 15-09-0382-00-004g 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.
