In-building
wireless systems use access points to provide wireless connectivity for radio
equipped client devices within a facility.
Supported client devices include but are not limited to: notebook PCs,
hand held terminals, PDAs, desktop PCs, IP cameras, scales, printers and IP
phones. Wireless users can roam within a site and maintain their network
connection as long as they are within the area of coverage provided by an
access point. Likewise, client devices can be easily added or moved within a
site without the need to install and run Ethernet cabling. |

Wireless “bridges”
are radio devices that connect Ethernet LANs to each other without requiring
cabling or leased line connections. The main requirement for successful
wireless bridging is that of “line of site”. In order to make a wireless
connection, bridge antennas must be able to “see” other with no obstruction
or objects between them. Depending on the speed of the wireless link, it is
possible to connect sites that are up to 23 miles apart. Facts about
wireless bridge systems: · Bridge antennas can sometimes be mounted behind windows panes—as long as line of sight is maintained between antennas and the glass panes do not inhibit RF signal due to coatings etc. · Bridge antennas and bridges can be “co-located”—that is they can share antenna masts and mounting locations and not interfere with each other. · Two bridges can be connected via Ethernet to each other, with antennas pointing in opposite directions to corresponding “parents” or “children”. This “hand off” approach is sometimes used to overcome line of sight issues. · Rain and snow have little or no effect on link quality between bridges. Although water absorbs 2.4 gHz radio signals, we have performed many packet tests in bad weather and have never encountered a problem. |
