Factors Affecting Wireless Signals
Because wireless signals travel through the atmosphere, they are susceptible to different types of interference than standard wired networks. Interference weakens wireless signals and therefore is an important consideration when working with wireless networking.
Interference Types
Wireless interference is an important consideration when you’re planning a wireless network. Interference is unfortunately inevitable, but the trick is to minimize the levels of interference. Wireless LAN communications typically are based on radio frequency signals that require a clear and unobstructed transmission path.
The following are some factors that cause interference:
Physical objects: Trees, masonry, buildings, and other physical structures are some of the most common sources of interference. The density of the materials used in a building’s construction determines the number of walls the RF signal can pass through and still maintain adequate coverage. Concrete and steel walls are particularly difficult for a signal to pass through. These structures will weaken or at times completely prevent wireless signals.
Radio frequency interference: Wireless technologies such as 802.11b/g use an RF range of 2.4GHz, and so do many other devices, such as cordless phones, microwaves, and so on. Devices that share the channel can cause noise and weaken the signals.
