You can start by creating a device-oriented (WX switches and MAPs) view of your network without any geographic information about your site—no floor dimensions, building material information, or RF obstacle information.
Page 32: Rf Auto-Tuning
Upload a WX switch configuration and deploy it. Enable the RF Auto-Tuning feature. This is a great way to install a WX switch and some MAPs, and observe how the network operates. The RF Auto-Tuning plan is best suited to networks containing fewer MAPs.
Page 33: Rf Planning
However, there are other requirements organizations should consider. 3Com recommends using the RF Auto-Tuning technique if you are installing MAPs without consideration to blanket coverage, throughput concerns, or the number of users for whom service will be provided. RF Auto-Tuning is ideal for small areas;...

You enable the MAPs to operate according to your planned RF coverage requirements.
Page 37 You must configure a radio profile to set attributes that you can apply to multiple radios. Rather than configuring each radio individually, you create a radio profile and apply it to multiple radios that you select. You can also create a radio profile as part of a policy and apply it to MAP access points on different WX switches.
Page 38: Aaa Security Configuration
Authentication is the method of determining whether a user is allowed access to your network. Users can be authenticated by a RADIUS server (pass-through) or by the WX switch local database (local). The WX switch can also assist the RADIUS server by performing the Extensible Authentication Protocol (EAP) processing for the server (offload).

RF neighborhood Statistics collected for the RF environment provides data on a per-channel basis. You can view noise levels, cyclic redundancy check (CRC) and PHY errors, packet retransmissions and percent utilization. Data collected for the RF neighborhood displays the neighboring radios. This information can be viewed as a list of radios heard by a particular radio, as well as a list of radios who can hear a particular radio.

Page 133: Model Rf Obstacles
Model RF Obstacles When planning a 3Com network, you need to consider how the building layout and physical objects affect signal loss. Walls, windows, and doors absorb RF signals, and different building materials have different attenuation factors. You can model an RF obstacle on your floor plan and assign the obstacle type and attenuation factor, or you can assign an obstacle type and attenuation factor to objects in a DWG or DXF drawing.
Page 134: Import A Site Survey
RF obstacles can be obtained and incorporated into your plan. This guide contains post-deployment information about optimization on “Displaying the RF Coverage Area” on page 189. For pre-deployment information about optimization, see “Optimizing a Network Plan” in the Wireless LAN Switch Manager Reference Manual.
Page 135: Plan Rf Coverage
Plan RF Coverage How you plan the RF coverage for your network depends on whether you are planning for the widest coverage or are planning for capacity. There are other contributing factors. One group of users may be mobile and require high throughput performance (a higher bandwidth), while another group of users are more stationary and require less throughput.
