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

What is the Big Difference? THEM US
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

§ Patented technology that combines: § Smart antenna arrays § Best path selection algorithms § Advanced quality of service engine § Smart mesh RF routing § Centralized Wi-Fi management
§ Adapts to real-time changes in environmental conditions
§ Extends signal range (Wi-Fi coverage) 2 to 4 times with fewer APs
§ Radically simplifies deployment and administration

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
