Elster AMCO Water’s evolution™ Advanced
Metering Infrastructure overview
Elster AMCO Water’s evolution™ Advanced Metering
Infrastructure (AMI) is a fixed network running a web-based
application on a Ground Server and an evoNet™ Manager Server
that handles two-way communication via the evoGate™ gateway.
The evoGate is referred to as a ‘gateway’ because it is the gate
between the 902 to 928 MHz evolution Radio Transceiver Module
(evoRTM™) Local Area Network (LAN) and Wide Area Network
(WAN) backhaul via a General Packet Radio Service (GPRS)
cellular radio or Ethernet connection. The evoGate is also referred
to as the Central Collector because it collects metering data from
all of the evoRTM/meter pairs in the network. As such, the
evoGate unit shall be referred to as the evoGate Central Collector
in this document.
The evoGate Central Collector provides two-way communications
on both the network side and on the WAN side. This capability
enables the utility company to acquire readings on demand and to
receive information regarding events such as leaks, tampering,
low battery conditions and reverse flow or backflow.
Figure 1 illustrates the interactions of the components of an Elster
AMCO Water evolution AMI system and this document briefly
discusses each.

evoRTM Radio Transceiver Modules
3B
The evoRTM endpoints are ‘Smart’ components of the Elster
AMCO Water fixed Advanced Metering Infrastructure network that
collect and analyze information directly from the water meter
register. The evoRTM endpoints can be installed some distance
from the meter, using a 3-conductor cable, or in a pit with the
meter using a pit-mount interface. For some new installations, the
evoRTM endpoint and the water meter can be purchased as a
single unit.
evoRTM
Endpoint
An evoRTM is required for each meter register that is read in an
AMI fixed network. The meters and evoRTM endpoints exist at the
data-collection end of the network. As such, they are rightly
referred to as ‘endpoints’. The evoRTM endpoints operate within
the 902-928 MHz Industrial, Scientific and Medical (ISM)
frequency range in a fixed network.
Because the evolution AMI system operates as a deterministic, or
modified, mesh network, the evoRTM can work in several different
configurations. The different configurations allow direct
communication with other evoRTM endpoints, an evoHop range
extender or directly with an evoGate Central Collector to ensure
effective and consistent transfer of information.

The evoRTM endpoints are able to use other nearby endpoints as
relays or repeaters to get data back to the evoGate Central
Collector. As shown in Figure 1, each relay through another
evoRTM is called a ‘hop’. The system allows up to four hops to
get from the source evoRTM endpoint to the evoGate Central
Collector using three other evoRTM endpoints as relays in
between. This is otherwise known as a ‘tree’ topology. The
evoRTM endpoints can also configure themselves in a ‘star’
topology where multiple endpoints can report through a single
endpoint. In Elster AMCO Water evolution fixed network ‘star’
configurations, a single evoRTM endpoint can support up to 10
other direct connections to other evoRTM endpoints. Greater
distances require an evoHop Range Extender.
A deterministic, or modified, mesh network reduces latency in
retrieving meter data because the system knows exactly where to
go to acquire data - unlike a 'full' mesh network where devices
blindly transmit data to any other device in the system. Random
paths can affect the battery life of devices by increasing the
number of devices and the amount of data each handles from
different directions on the way to the central collector. The
evolution AMI system configures itself to optimize the number of
hops and connections between the evoRTM Endpoints to ensure
that no one endpoint is handling an excessive amount of traffic,
which would possibly shorten battery life. As a result, long battery
life for all modules in the network is ensured.
evoHop Range Extenders
4B
The evoHop range extenders are wireless relays designed to
extend the operating range of evoRTM endpoints in a fixed
network. The evoHop units look and perform similarly to evoRTM
endpoints but are not programmed or connected to a water meter
register. The number of evoHop units required for a fixed network
varies depending on the topology, as well as the number and
location of evoRTM endpoints and evoGate Central Collectors. An
Elster AMCO Water Tech Support Specialist completes a detailed
survey to determine the required number and location of evoHop
units.
evoGate Central Collectors
5B
evoGate Central Collectors are the evolution network-to-cellular
GPRS gateways and serve as central collecting points for meter
data. evoGate Central Collectors communicate with the evolution
Ground Server either via cellular GPRS or through an Ethernet
connection.

The number of evoGate Central Collectors required for a fixed
network varies depending on the number and location of evoRTM
endpoints and evoHop units. An Elster AMCO Water Tech
Support Specialist completes a detailed survey to determine the
required number and location of evoGate Central Collectors.
GPRS communication requires that a unique SIM card be installed
in each evoGate Central Collector. An Elster AMCO Water
Technical Support Specialist will assist with the procurement and
activation of each SIM card before installation. Like any cellular
device a monthly fee is assessed to the utility company for each
GSM/GPRS access point.
evolution Ground Server
6B
The evolution Ground Server is the bridge between the evoGate
Central Collectors and the evoNet Manager Server, where the
main application resides. In order to exchange commands
between the evoGate Central Collectors and the evoNet Manager
Server, the evolution Ground Server must have a dedicated
Internet connection. Elster AMCO Water recommends at least a
3Mb/s dedicated connection using DSL or high speed cable
through an Internet Service Provider (ISP).
The evolution Ground Server is configured and tested with
Microsoft® Windows® 2003 Server SP2 software by an Elster
AMCO Water Tech Support Specialist. Additionally, the Elster
AMCO Water Tech Support Specialist installs and activates the
Ground Server software required for the fixed network.
Router
7B
The evolution Ground Server communicates with the evoNet
Manager Server via a router. The router ensures effective and
consistent communication between the evolution Ground Server
and the evoNet Manager Server.

evoNet Manager Server
8B
The evoNet Manager Server is the server component in a fixed
network that stores and manages evoRTM endpoint data. The
evoNet Manager software uses Oracle or MySQL databases to
manage the data. Standard reporting options in the evoNet
Manager application include:

Consumption (high/low)

Negative or Zero Consumption

Tampering or Misreading

Unassigned or Hard-to-read evoRTM

General Readings and Leak Detection

General Statistics and Collector Status
The evoNet Manager Server is shipped to Elster AMCO Water
where an Elster AMCO Water Tech Support Specialist installs and
activates the evoNet Manager software.
evoWalk fixed network handheld field unit
9B
An AMI fixed network includes an evoWalk FN handheld device to
provide technicians a tool to communicate and debug evoRTM
endpoints in the field. It is necessary to communicate with
evoRTM endpoints in the field if two-way communication between
the endpoint and the evoGate Central Collector is lost, and to
repair and replace evoRTM endpoints in the field.
The evoWalk FN handheld mobile unit is configured and tested by
an Elster AMCO Water Tech Support Specialist. Training is also
provided to the utility’s field service personnel.
