A Smart metering utility network (SUN), as defined by IEEE 802.15.4g, enables the wireless transfer of controlx000D
and information data in smart grids for diverse applications, including smart metering. Trilliant Networksx000D
(Canada) Inc. currently deploys smart metering solutions in very demanding conditions in terms of customerx000D
Service Level Agreement (SLA) requirements, density of smart meter devices per square km, as well as in veryx000D
challenging environments such as underground areas, high rise buildings, etc. Smart meters and data collectionx000D
nodes are interconnected using a wireless mesh topology to expand communication range and cater to highx000D
density setups reaching up to ten thousand units per square kilometer. These devices use IEEE 802.15.4g withx000D
multi-regional multiple-rate orthogonal frequency division multiplexing (MR-OFDM), where multiple datax000D
rates from 50kbps up to 800kbps can be supported. New devices using Frequency-shift keying (FSK) will alsox000D
be used in future by Trilliant Networks (Canada) Inc. In collaboration with Trilliant Networks (Canada) Inc.,x000D
we will perform a systemic study to clearly analyze the behavior of one technology versus the other in typicalx000D
deployments. Further, in order to enhance the performance of both used technologies, we will develop a novelx000D
technique for rate adaptation that is non-computationally demanding, is robust against sporadic losses whilex000D
being responsive to severe channel changes, and that takes into account the mesh topology of the network. Thex000D
technique will be readily deployable without a costly hardware redesign of existing Trilliant Networksx000D
(Canada) Inc. equipment, and is aimed to significantly enhance the performance of the smart meteringx000D
networks.x000D
We will integrate the technique into Trilliant Networks (Canada) Inc test bed equipment, and we will conductx000D
field tests to validate the results. The advancements made in this project will provide an important competitivex000D
edge for Trilliant Networks (Canada) Inc. and contribute to leading edge technology for smart grids, providingx000D
Canada with an opportunity for global leadership in the area.
