Determining Deployment Requirements
Determining Deployment Requirements
There are a few important deployment criteria to consider when deploying a wireless network:
•
•
•
•
•
•
•
Most enterprise installations are initially designed and deployed for coverage. If there is a large installed
Note
base of wireless clients, capacity must also be considered.
Assumptions
The guidelines in this document are written based on the following conditions and assumptions:
•
•
•
•
•
These assumptions are typical for available 802.11 client data terminals and typical cubicle density.

Assumptions
Protocol Requirements
Coverage Area Requirements
Building Type
Building Homogeneity
Average Client Throughput
Voice over IP Requirements
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.
