IT departments to deploy wireless networks with existing resources, and system integrators to design and deploy wireless networks with greater predictability. The Radio Resource Management (RRM), which is part of the Cisco WLAN Solution detects coverage holes and interference and automatically determines transmit power level and transmit channels for each Cisco 1000 series lightweight access point, which allows the Cisco WLAN Solution to be deployed without a site survey when the building RF characteristics are well known. -

10 percent. This means that between two and ten test locations out of 100 random test locations may receive marginal service. After launch, the Cisco WLAN Solution Radio Resource Management (RRM) will identify these coverage areas and report them to the IT manager, allowing the IT manager to fill holes based on user demand. -
Page 22: Building Type
Determining Deployment Requirements Building Type Identifying the building type and its RF characteristics is critical in determining how many Cisco Radios will be needed. The following table shows three basic building types that are common in the enterprise market. If the building does not fall into one of these categories then some amount of professional service may be needed. - Page 23 Figure 1 Average Client Throughput versus Signal Strength The following figures show the relationship between average client performance and Cisco 1000 series lightweight access point density for 802.11a and 802.11b clients. The typical Cisco 1000 series lightweight access point density for most enterprise buildings deployed for full coverage is between 2500 and 7000 square feet per Cisco 1000 series lightweight access point.

Page 27: Professional Site Survey
The professional site survey allows the designer to provide full seamless coverage; however, the Radio Resource Management (RRM) ensures that the channel assignments and transmit power levels are optimized for the Cisco WLAN Solution coverage area, freeing the site survey professional from having to fine-tune these variables. -
Page 28: Basic Guidelines With Optional Site Survey
Determining the Radius and Z Factor This section helps you to determine the coverage area of a Cisco Radio based on the building type and desired average user performance using the table below. The Z factor represents the length of a square that corresponds to the coverage area of the access point. - Page 29 2500 3000 3500 4000 4500 5000 5500 6000 6500 7000 7500 8000 The following graph displays actual measurements, and shows the relationship between actual user throughput and corresponding signal strength.

12 Mbps a signal strength of -75 dBm or better is needed and the site survey will be used to verify that the -75 dBm coverage radius of a Cisco 1000 Series lightweight access point is 50 feet. Review the “Optional Minimal Site Survey” section of this document for how to perform a site survey using a Cisco 1000 Series lightweight access point. -
Page 32: Placing Access Points
Note that the large “X” in the middle of each coverage area indicates the approximate location of the Cisco 1000 series lightweight access points. Also notice that the Z factor between the centers of each Cisco 1000 series lightweight access point location is the same as the Cisco 1000 series lightweight access point squares when the squares are directly adjacent to each other, as shown in this figure. -
Page 33: Collecting Tools And Materials
You do not need to use the optional Cisco 1000 series lightweight access point tripod test assemblies described in this section--you can tape or cable tie the Cisco 1000 series lightweight access points to the ceiling, or place them on tall cabinets or ladders. However, if you must move them from their original positions, having them mounted on the tripod test assembly stands makes it easier to relocate them. -
