Where possible, minimize the distance from the access point to the furthest Ranger
Pro device.
4. Plan for multiple connections for each device.

o
Multiple communication paths are required to increase network redundancy and
prevent a single path failure that would result in a loss of communication.

o
Depending on the circle (short, medium, or long) that applies to the location of each
Ranger Pro sensor, verify that each device is within range of at least two, and
preferably three, routing devices or access points.

o
Avoid connecting more than five devices through a single Ranger Pro ISA100 sensor,
or more than eight devices through a single Ranger Pro ISA100 Repeater.
5. To extend the range of an ISA100 wireless network or to reach devices beyond the range of
a gateway or an backbone router, consider adding Ranger Pro repeaters. Repeaters ought
to be positioned:

o
Relatively high above the sensors, preferably at least two meters (6 ½ feet) above
grade. Higher placement dramatically increases signal strength.

o
To improve radio frequency transmission, we recommend you install the repeaters
upside down and at least 33 cm (1 ft) from walls and pillars.

o
Within a clear line of sight to two other repeaters or access points.
6. Plan for a maximum of four hops between each Ranger Pro device and a gateway,
backbone router, or access point, although we recommend a maximum of three hops.
7. If your installation is complex or likely to require additional gateways, backbone routers, or
access points, consider temporarily installing your network access points and Ranger Pro
devices to test your plan. Use temporary magnetic mounting adapters to test device
placement.
To obtain optimal results, carefully plan your network. For complete information, see your
network infrastructure documentation.
