Wireless Installation Considerations
The DCS-8515LH connects to your network using a wireless connection from anywhere within the operating range of your
wireless network. However, the number, thickness and location of walls, ceilings, or other objects that the wireless signals
must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio
frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:
1. Minimize the number of walls and ceilings between your adapter and other network devices - each wall or
ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters).
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.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
your devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better
reception.
3. Building materials make a difference. A solid metal door or aluminum studs may weaken the wireless signal. Try
to position your access points, wireless routers, and other networking devices where the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (fish
tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product at least 3-6 feet or 1-2 meters away from electrical devices or appliances that generate RF
noise.
5. If you are using 2.4 GHz cordless phones or other radio frequency sources (such as microwave ovens), your
wireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz phone base is as
far away from your wireless devices as possible. The base transmits a signal even if the phone in not in use.
