! NOTE

Where possible, minimize the distance from the gateway, backbone router or access point to the

furthest VP Series 2000 device.

4. Plan for multiple connections for each device.

• Multiple communication paths in mesh networks are required to increase network redundancy

and prevent a single path failure that would result in a loss of communication.

• Depending on the circle (short, medium, or long) that applies to the location of each

VP Series 2000 device, verify that each device is within range of at least two, and preferably

three, routing devices or access points.

• Avoid connecting more than five devices through a single VP Series 2000 ISA100 sensor with

routing enabled, or more than eight devices through a single VP Series 2000 ISA100 repeater.

5. To extend the range of an ISA100 wireless network or to reach devices beyond the range of a gateway

or backbone router, consider adding VP Series 2000 repeaters. Repeaters ought to be positioned:

• Relatively high above other devices, preferably at least two meters (6 ½ feet) above ground.

Higher placement dramatically increases signal strength.

• To improve radio frequency transmission, we recommend you install the repeaters upside down

and at least 33 cm (1 ft) from walls and pillars.

• Within a clear line of sight to two other repeaters or a backbone router.

6. Plan for a maximum of four hops between each VP Series 2000 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 gateways, backbone routers or access points and

VP Series 2000 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.
