The 802.11bgn 2.4 GHz band is commonly used today and is an open standard shared by everyone.
Channel selection is limited and regulated to a certain extent, but it is also very common to have
channels overlapping and operating side by side competing for bandwidth and causing interference with
one another.
In the case of WLANs, the presence of RF interference sources
can strongly reduce performance by causing errors
and re-transmissions. It is vital to identify such
sources at the start of an implementation and attempt
to avoid or eliminate them as much as possible.
This presents a significant challenge because
noise sources, rougues, and WiFi neighbors are
often intermittent, difficult to measure, and a
nightmare to find! This is an essential part of
a good Wireless network plan, a key peice that
White Wing will provide.
For instance, the most often used frequency falls under
802.11bgn in the 2.4 GHz band. 802.11bgn WLAN channels operate in a frequency
band between 2.4 - 2.5 GHz. The channels are
graphically shown below (11 in North America and 13 in most other countries):
2.4Ghz channels will overlap, so the simultaneous use of nearby channels will
interfere with each other. If the channels are used intermittently then this interference
will be infrequent. With steaming voice and video however, this occurs on a continuous
basis, and results in the diminishment of range and performance. Want help to avoid
these and many other unseen issues to create an optimized Wireless network?
