With
IntelliNet networks, information going to or coming from an IntelliNet
device from a remote location is hopped from one Intellinet device
to another. Once a geographic area is effectively ‘seeded' with
the minimum number of units to cover the geographic area (again
3-20 miles per IntelliNet device), the network is in place. The
network develops additional capacity simply by adding more units
to the network. A single frequency can provide capacity for tens
of thousands of Intellinet network devices and multiple frequencies
are available in every metropolitan area.
Each smart network device
acts as both a transmitter and receiver for communicating information
to other network devices that make up its network. Monitoring or
control information to and from each device is sent through the
IntelliNet network to a central station. The signal is transmitted
directly to the central station if the subscriber is within wireless
reception range, or is relayed through one or more of these IntelliNet
network devices to get to the central station.
As each network device is placed in
a geographic network of these devices, the network device automatically
self-configures itself to become part of the network to send, receive
and relay messages through the network. As more IntelliNet network
devices are placed in a given geographic area, the network coverage
across a geographic area is expanded with no practical limits.
An AES-IntelliNet wireless
mesh network, is composed of two basic elements:
Central Monitoring Station
(CMS)
The CMS is the central hub of an AES-IntelliNet data communications
network. It is the primary computer platform to which data
from the SSTs is received and from which outgoing data is sent.
It converts the data from the wireless format to the digital format,
which then interfaces with the monitoring software and peripherals.
The CMS is housed at a central location, and provides the following:
- Receives all data messages from the radio network.
- Acknowledges all data messages from the radio network.
- Annunciates inbound data, systems faults & warning conditions.
- Outputs system activity to a printer.
- Manages the Network Controller and Network Management Software.
Smart Subscriber Transceiver
(SST)
The SST is the remote AES-INtelliNet device that enables the remote
monitoring and control of a remote device (alarm, meter, etc.).
Geographically dispersed at remote locations, the Smart Subscriber
Transceiver is connected to the monitored device. If the SST is
in geographic radio range (typically 3-5 miles but often quite a
bit greater), then it communicates directly with the CMS. If not,
the SST relays its message to another SST closer to the CMS. This
2nd Subscriber Unit acts as a store-and-forward message repeater
for other SSTs that are beyond direct radio reach of the central
station. Each SST dynamically evaluates and stores information on
all possible ?routes? through which it can send messages to the
CMS.
These two primary elements
utilize common 2-5 Watt radio components that allow them to send
and receive wireless data on a single UHF or VHF radio frequency.
The frequency is private and known only to the operator.
