System Requirements
                       A 2.4-GHz Cisco device that utilizes a RP-TNC connector.



Installation Notes
                       Because antennas transmit and receive radio signals, they are susceptible to RF obstructions and
                       common sources of interference that can reduce throughput and range of the device to which they are
                       connected. Follow these guidelines to ensure the best possible performance:
                        •    Mount the antenna to utilize its propagation characteristics. A way to do this is to orient the antenna
                             horizontally as high as possible at or near the center of its coverage area.


            Note       The antenna must be mounted horizontally in order to maximize its omnidirectional propagation
                       characteristics. Mounting it vertically may noticeably decrease the antenna’s range and overall
                       performance.

                        •    Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large
                             ceiling trusses, building superstructures, and major power cabling runs. If necessary, use a rigid
                             conduit to lower the antenna away from these obstructions.
                        •    The density of the materials used in a building’s construction determines the number of walls the
                             signal must pass through and still maintain adequate coverage. Consider the following before
                             choosing the location to install your antenna:
                              – Paper and vinyl walls have very little affect on signal penetration.
                              – Solid and pre-cast concrete walls limit signal penetration to one or two walls without degrading
                                 coverage.

                                                                                                                  Installation Notes




                     – Concrete and wood block walls limit signal penetration to three or four walls.
                     – A signal can penetrate five or six walls constructed of drywall or wood.
                     – A thick metal wall causes signals to reflect off, causing poor penetration.
                     – A chain link fence or wire mesh spaced between 1 and 1 1/2 in. (2.5 and 3.8 cm) acts as a
                        harmonic reflector that blocks a 2.4 Ghz radio signal.
                •   Install the antenna away from microwave ovens and 2-GHz cordless phones. These products can
                    cause signal interference because they operate in the same frequency range as the device to which
                    your antenna is connected.
                •   Install the antenna horizontally to maximize signal propagation.



Installation Notes
               This antenna is designed to be mounted indoors on a suspended ceiling track having either flush or
               recessed mounted ceiling tiles.



Safety Instructions
               Follow these safety instructions when installing your antenna.
                •   Plan your installation procedure carefully and completely before you begin.
                •   If you are installing an antenna for the first time, for your own safety as well as others, seek
                    professional assistance. Consult your dealer, who can explain which mounting method to use for
                    the location where you intend to install the antenna.
                •   Select your installation site with safety, as well as performance, in mind. Remember that electric
                    power cables and telephone lines look alike. For your safety, assume that any line is an electric
                    power line until determined otherwise.
                •   Call your local power company or building maintenance organization if you are unsure about cables
                    close to your mounting location.
                •   When installing your antenna, do not use a metal ladder. Do dress properly - shoes with rubber soles
                    and heels, rubber gloves, and a long sleeved shirt or jacket.
                •   If an accident or emergency occurs with the power lines, call for qualified emergency help
                    immediately.

Cisco TAC Web Site
                The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The
                site provides around-the-clock access to online tools, knowledge bases, and software. To access the
                Cisco TAC Web Site, go to the following URL:
                http://www.cisco.com/tac
                All customers, partners, and resellers who have a valid Cisco services contract have complete access to
                the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a
                Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or
                password, go to the following URL to register:
                http://www.cisco.com/register/
                If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com
                registered, you can open a case online by using the TAC Case Open tool at the following URL:
                http://www.cisco.com/tac/caseopen
                If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC
                Web Site.


Cisco TAC Escalation Center
                The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority
                level 2; these classifications are assigned when severe network degradation significantly impacts
                business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC
                engineer will automatically open a case.
                To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following
                URL:
                http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
                Before calling, please check with your network operations center to determine the level of Cisco support
                services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network
                Supported Accounts (NSA). In addition, please have available your service agreement number and your
                product serial number.
