Wireless Installation Considerations
The D-Link

DCS-G900 can be integrated into a wireless network from virtually anywhere
within its operating range. However, the range can be limited by the number of walls, thickness
of walls, and location of the walls that the wireless signal must pass through. 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:
Keep the number of walls and ceilings between the DCS-G900 and other network
devices to a minimum. Each wall or ceiling can reduce your DCS-G900’s range from
3-90 feet (1-30 meters).
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 devices so that the signal will
travel straight through a wall or ceiling (instead of at an angle) for better reception.
Building materials can impede the wireless signal. A solid metal door or aluminum
studs may have a negative effect on the range. Try to position wireless devices and
computers with wireless adapters so that the signal passes through drywall or open
doorways and not other materials.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that generate RF noise.
You can also add a directional antenna to help with range and sensitivity issues.
