2 Before you Begin
This section will guide you through the installation process. Placement of the
EnGenius ALL02880ND is essential to maximize the access point’s performance. Avoid
placing the ALL02880ND in an enclosed space such as a closet, cabinet, or stairwell.
2.1 Considerations for Wireless Installation
Generally, the exact operating distance of a wireless device, like the ALL02880ND,
cannot be pre-determined due to a number of unknown variables or obstacles in the
environment in which the device will be deployed. These could be the number,
thickness, and location of walls, ceilings, elevator shafts, stairwells, or other objects
that the device's wireless signals must pass through. Here are some key guidelines to
allow the ALL02880ND to have optimal wireless range.
 Keep the number of walls and/or ceilings between the ALL02880ND and other
network devices to a minimum. Each wall and/or ceiling can reduce the signal
strength, resulting in lower signal strength.
 Building materials make a difference. A solid metal door and/or aluminum studs
may have a significant negative effect on the signal strength of the ALL02880ND.
Locate your wireless devices carefully so the signal can pass through drywall
and/or open doorways. Materials such as glass, steel, metal, concrete, water
(example: fish tanks), mirrors, file cabinets and/or brick can also diminish wireless
signal strength.
 Interference from other electrical devices and/or appliances that generate RF
noise can also diminish the ALL02880ND’s signal strength. The most common
types of devices are microwaves or cordless phones.
