Introduction► Maven systems is a product engineering company with an
expertise in providing end to end solutions for automatic meter reading.
► AMR solutions are based on LPRF, PLC and GPRS technologies► Hands on expertise on ZigBee, proprietary mesh, 6LoWPAN,
DLMS, Modbus, KNX, M-Bus protocols to name a few.► Multiple pilots based on LPRF based technologies are in place
based on Sub 1 GHz (865- 867 MHz) and 2.4 GHz technologies.
► Both technologies have their set of advantages / disadvantages and in the course we have benefited with substantial learning and observations about implementations of AMR.
2.4 Ghz Sub 1 Ghz (865- 867 MHz)

Deployment scenario
AMR Frame work
Pre requisites of a successful AMR implementation► Robust and appropriate technology for last milestone connectivity
► Ease of data collection with user friendly customer touch points
► Ease of implementation and deployment
► Reliable system with low maintenance
► Lower implementation and operational costs
► Stable and self healing networks
Important
► Capability to capture accurate base line data which could be closely linked with generation capacity and distribution management
► The implementation should be scalable to a AMI, smart grid implementation with minimal changes and efforts.
Maven’s mesh network protocol
Topics
► Adhoc on-demand routing
► Mesh advantages
► Data concentrator
Adhoc on-demand routing► Network is silent until a connection/ data is needed
► Eliminates the efforts of identifying the locations for the coordinator, routers for data fetching. o In case of ZigBee if the coordinator fails then data cannot be
fetched till the time coordinator is restored and the network is created again.
► Installation process is simpler and connection setup delay is lower
► Data can be fetched on demand and / or at regular interval
Mesh advantages► Cost effective and dynamic high bandwidth networks over a
specific coverage area
► Self healing in case of failures of one of the meters in the path
► Auto discovery helps identify the newly introduced meters
► Reduces the efforts of meter commissioning
► PAN ID is used to create the specified coverage area
Data concentrator► Data concentrator can cache the history data up to 1000 meters
along with time stamp as it has larger memory available.
► DC has a list of meters to be polled and the polling duration at which the data can be cached from meters.
► DC uploads the cached data when GPRS connection is available else would store the data and upload it offline when GPRS connectivity is available.
► Cached data on server can be used for billing, plotting the usage patterns and / or energy profiling.
► Hand held unit can also collect the cached data from the DC
