Determining Deployment Requirements Deployment Determining Deployment Requirements There are a few important deployment criteria to consider when deploying a wireless network: • Assumptions • Protocol Requirements • Coverage Area Requirements • Building Type • Building Homogeneity • Average Client Throughput • Voice over IP Requirements Note Most enterprise installations are initially designed and deployed for coverage. If there is a large installed base of wireless clients, capacity must also be considered. Assumptions The guidelines in this document are written based on the following conditions and assumptions: • Client Data Terminal Transmit (Tx) Power: >=15 dBm. • Client Data Terminal Antenna Gain: >=0 dBi. • Capacity: up to 15 Data client Terminals or up to 14 VoIP clients per Cisco 1000 series lightweight access point. • Handover Times: 37 milliseconds or less for Layer 2 (same- Cisco 4100 Series Wireless LAN Controller) handovers, 48 milliseconds or less for Layer 3 (inter-Cisco 4100 Series Wireless LAN Controller and inter-subnet) handovers. • Quality of Service: Assigned on a per-WLAN basis. VoIP clients with Platinum QoS take precedence (up to 90+% of bandwidth) over clients with Gold, Silver or Bronze QoS. Note These assumptions are typical for available 802.11 client data terminals and typical cubicle density. Deployment Guide: Cisco Aironet 1000 Series Lightweight Access Points 2 78-17279-01
