We have extensive experience performing wireless site surveys and installations in warehousing, manufacturing, retail, healthcare, commercial and residential facilities. Our technology specializations include 802.11a, 802.11b, 802.11g, Wi-Fi, and bridging. We provide spectrum analysis, performance recommendations, hardware and software configuration upgrades, and security analysis. Our clients include medium and small businesses, government agencies, as well as owners of private residences.

When considering the use of wireless equipment, it is extremely difficult to predict the propagation of radio waves and detect the presence of interfering signals without the use of specialized test equipment. Even if you are using omni-directional antennas, radio waves do not travel the same distance in all directions. Walls, doors, elevator shafts, people, and other obstacles offer varying degrees of attenuation, which cause the radio frequency (RF) radiation pattern to be irregular and unpredictable. As a result, one should have an RF site survey performed to understand fully the behavior of radio waves within a facility before installing any wireless devices.
 


IEEE 802.11
 - 802.11 is a family of wireless networking standards developed by the IEEE, including the most common 802.11a, 80211b, and 80211g. Other standards in this family include 802.11e, 802.11h, and 802.11n.

802.11a
 - One of three wireless networking specifications under the Wi-Fi rubric. 802.11a uses the 5 GHz band and runs at 54 Mbps. 802.11a is little used outside specific business situations.

802.11b
 - The most common of the three wireless networking specifications included in the Wi-Fi certification mark. 802.11b uses the 2.4 GHz band and runs at 11 Mbps.

802.11g
 - The newest of the three Wi-Fi specifications. 802.11g is backward compatible with 802.11b, thanks in part to its use of the 2.4 GHz band, and provides over 20 Mbps on the 2.4GHz band. It is compatible with 802.11b. Both 802.11b and 802.11g have effective ranges of about 300 feet. Most new equipment uses 802.11g.

802.11e
 - A wireless standard that provides Quality of Service support for LANs. This is necessary for delay-sensitive applications such as Voice over Wireless IP. The standard is under development and isn't expected until late 2004.

802.11n
 - A standard reportedly in the works that would boost 802.11a and 802.11b speeds to 108 Mbps and higher. 802.11n is not yet official and isn't expected to be complete until 2005 at the earliest.
