1.5. Before you Begin

This section will guide you through the installation process. Placement of the ESR150H is very important to avoid poor
signal reception and performance. Avoid placing the device in enclosed spaces such as a closet, cabinet or wardrobe.

1.6. 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.
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.
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.
Interferences can also come from your other electrical devices or appliances that generate RF noise. The most usual
types are microwaves, or cordless phones.
