Mesh Technology
How It Works:
AES-IntellliNet wireless mesh network, as illustrated
in Figure
1, utilizes the following principles:
- There
is a remote transceiver used to monitor or control
a device such as an alarm panel.
- Each
transceiver relays its data in distances measured
in miles, to the central receiver via radio transmission.
- If
the transceiver is too far to reach the central
receiver directly, it simply hops the data to the
next closest transceiver and that transceiver relays
it to the central receiver or to the next closest
transceiver to the central receiver.
- The
Central Receiver relays the data to alarm automation
software for processing.
- If
data can not be relayed via one route, the mesh
network automatically selects the next best route
from a choice of up to 8 available routes at any
given time.
- The
network dynamically and automatically adapts to
changes in the network caused by weather changes,
obstruction changes, the addition or subtraction
of other transceivers in the network, etc. so that
it is highly redundant and reliable.

Geographically Separated Networks:
Wireless
mesh networks operate very well in areas where there is a
relative density of remote transceivers to form the network.
Such as across a campus, city, region, state or even country.
However, there are some applications which have pockets of
remote transceivers such as 2 separate cities, which may be
have great distances (perhaps hundreds of miles between them)
which want to benefit from the wireless mesh technology.
In this case, where it might not be practical to add a lot
of remote transceivers between the cities to bring the two
city-wide networks together, there is Internet technology
to bridge the gap. AES-MultiNet technology, as illustrated
in Figure 2, utilizes the same principles as the single wireless
mesh network with the following additional principles:
- When
the data reaches the edge of the single wireless mesh
network, it is collected at a central concentrator called
an IP Link.
- The
IP Link receives the wireless data, converts it to TCP/IP
and relays it over the Internet to the Central Receiver.
- The
Central Receiver relays the data to alarm automation software
for processing.
Wireless
Mesh Benefits: The results are that a wireless mesh
network provides more reliability, more redundancy and faster
signal transmission than any wired or wireless network technology
available. Furthermore, since the monitoring transceivers
themselves make up the network negating the need for radio
towers, the network is self enrolling and managing negating
the need for real radio engineering expertise, and the fact
that there are no monthly fees paid to a network operator
to maintain this network, a wireless mesh network offers the
lowest cost of ownership possible. |
