Determining Deployment Strategy Deployment Voice over IP Requirements When deploying 802.11 wireless LANs to support Voice over IP (VoIP) telephones, such as SpectraLink NetLink Telephones, a few special considerations are needed in the deployment process. When deploying an 802.11b voice system, seamless full coverage with an average user throughput of 5 Mbps or more should be used. Areas such as stairways, bathrooms, cafeterias and outside areas may require special consideration and additional access points. These are areas that are not typically critical for data users but are critical coverage areas for voice users who want seamless coverage. Determining Deployment Strategy Depending on the customer and the deployment requirements determined in "Determining Deployment Requirements," there are three strategies for designing and deploying an Cisco WLAN Solution wireless network. The following table provides guidelines for which one is appropriate. Table 5 Deployment Strategy Deployment Option Professional Site Survey RF Prediction with Optional Site Survey Basic Guidelines with Optional Site Survey Deployment Requirements This option should be considered when: • Deployments require full coverage with 0% coverage holes. • The RF characteristics of the building vary throughout the coverage area. • The building type is not typical or does not fit into one of the standard configurations (e.g. Arena, Convention Center, Stock Exchange). • The cost or logistics of running Ethernet cables is prohibitive. This option should be considered when: • The RF characteristics of the building vary throughout the coverage area. • The building type is not typical (e.g. Arena, Convention Center, Stock Exchange). • A Professional Site Survey is too costly, and a graphical coverage plot is desired before deployment. This option is adequate for 80% to 90% of deployments, and is suitable when: • The RF Characteristics are homogenous throughout the coverage area. • The building type can be easily classified.
