4 Before you Begin
This section will guide you through the installation process. Placement of the Range Extender is very
important to avoid poor signal reception and performance. Avoid placing the device in enclosed spaces
such as a closet, cabinet or wardrobe.
4.1 Considerations for Wireless Installation
The operating distance of all wireless devices cannot be pre-determined due to a number of
unknown obstacles in the environment that the device is deployed. These could be the number,
thickness and location of walls, ceilings or other objects that the wireless signals must pass through.
Here are some key guidelines to ensure that you have the optimal wireless range.
1. Keep the number of walls and ceilings between the EnGenius access point and other network
devices to a minimum. Each wall or ceiling can reduce the signal strength, the degradation
depends on the building’s material.
2. Building materials makes a difference. A solid metal door or aluminum stubs may have a significant negative effect on
range. Locate your wireless devices carefully so the signal can pass through a drywall or open doorways. Materials such
as glass, steel, metal, concrete, water (fish tanks), mirrors, file cabinets and brick will also degrade your wireless signal.
3. Interferences can also come from your other electrical devices or appliances that generate RF noise. The most usual
types are microwaves, or cordless phones.
