Limited Choices for the Enterprise
Unfortunate 50,000 ENTERPRISE ▪ Feature-rich ▪ Simple to install ▪ Affordable ▪ Reliable ▪ Multiple APs ▪ 100s-1000s of users ▪ Limited IT staff CONSUMER/SOHO
▪ Cheap ▪ Lack features ▪ Hard to manage ▪ Single AP ▪ Lacks security features
FORTUNE 500 ▪ Costly, complex, and cumbersome ▪ Difficult to deploy and manage ▪ Designed for 10,000+ users
1. Wi-‐Fi is undependable, signal strength erra6c 2. Performance is inconsistent 3. Signals don’t reach, coverage is spoNy 4. Wireless LAN systems are costly, cumbersome, and complex

Fixed 1:1 relationship between Wi-Fi radios and antennas
Dynamic 1:many relationship between Wi-Fi radios and antennas
Industry’s Best Performing • Integrated high-‐gain adap6ve antenna
technology – 2 to 4x the coverage means fewer
APs required – Consistent performance at range – More reliable connec6ons – Automa6c interference avoidance
• No Ethernet cable required • Sophis6cated QoS engine • Standard PoE support (802.3af) • Works with or without controller
Auto RF signal optimizer

Success Factors for WLAN Deployments Success Factors for WLAN Deployments ▪ Site Survey
▪ Establish and maintain a minimum signal strength of -‐65dBm ▪ Use ac6ve site survey tools vs. passive tools
▪ Leverage 802.11ac to ensure low latency & improve signal quality ▪ Do not over-‐saturate with too many access points. Deploy intelligent technology to provide consistent RF experience ▪ Be sure to consider polarity in deployment (iPad held ver6cal and horizontal) ▪ BaNery life considera6ons ▪ AP seongs to improve iPhone roaming
