1.2. Wireless Performance Considerations
There are a number of factors that can impact the range of wireless devices.
1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at
an angle. The more material the signal has to pass through the more signal you will lose.
2. Keep the number of obstructions to a minimum. Each obstruction can reduce the range of a
wireless device. Position the wireless devices in a manner that will minimize the amount
of obstructions between them.
3. Building materials can have a large impact on your wireless signal. In an indoor
environment, try to position the wireless devices so that the signal passes through less
dense material such as dry wall. Dense materials like metal, solid wood, glass or even
furniture may block or degrade the signal.
4. Antenna orientation can also have a large impact on your wireless signal. Use the wireless
adapter’s site survey tool to determine the best antenna orientation for your wireless
devices.
5. Interference from devices that produce RF (radio frequency) noise can also impact your
signal. Position your wireless devices away from anything that generates RF noise, such
as microwaves, radios and baby monitors.
6. Any device operating on the 2.4GHz or 5GHz frequency will cause interference. Devices
such as 2.4GHz or 5GHz cordless phones or other wireless remotes operating on the
2.4GHz or 5GHz frequency can potentially drop the wireless signal. Although the phone
may not be in use, the base can still transmit wireless signal. Move the phone’s base
station as far away as possible from your wireless devices.
If you are still experiencing low or no signal consider repositioning the wireless devices or
installing additional access points. The use of higher gain antennas may also provide the
necessary coverage depending on the environment.
