(Wireless) Designed to support ranges of 984 feet (300 meters) outdoors and up to 328 feet
(100 meters) indoors, the DeviceMaster AIR allows you to access your serial
devices wirelessly from virtually anywhere within its operating range.
Keep in mind, that the number, thickness and location of walls, ceilings or other
objects that the wireless signal must pass through may limit range. Typical ranges
vary depending on the types of materials and any background RF (radio
frequency) noise in your environment. The key to maximizing range is to follow
these basic guidelines:
1. Keep the number of walls and ceilings between the DeviceMaster AIR and
your receiving device (access points, residential gateways, and computers) to a
minimum. Each wall or ceiling can reduce your DeviceMaster AIR unit’s range
from 3 to 90 feet (1 to 30 meters).
2. Be aware of the direct line between the DeviceMaster AIR and the device with
which it communicates, as well as between access points, residential gateways
(routers), and computers. A wall that is 1.5 feet thick (0.5 meters), at a 45-
degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it
looks over 42 feet (14 meters) thick. Position access points and Adapters so
that the signal will travel straight through a wall or ceiling (instead of at an
angle) for better reception.
3. Building Materials can impede the wireless signal. A solid metal door or
aluminum studs may have a negative effect on range. Try to position the
DeviceMaster AIR, the access points, and computers with wireless adapters so
that the signal passes through drywall or open doorways and not other
materials.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices
or appliances that may generate extreme RF noise.
