3 Agenda Market Drivers Retail Healthcare The Enterprise ac - Distinctively Different! Design Tips/Tools/Strategies

4 Retail - Federal Reserve System Study How do shoppers want to use their smartphone? 48% to compare prices while shopping 33% to receive location driven promotions 31% to receive discounts and coupons 25% POS 23% to purchase tickets to events Source: Consumers and Mobile Financial Services, March 2012 Board of Governors of the Federal Reserve System

5 Retail - Enhancing the Customer Experience Self Service 63% Use Smartphones for Product and Price Comparison and Reviews (up from 48% in two years) Check Inventory and Place Orders Store Maps Product Location Customer Loyalty Programs Customized Digital Signage POS

6 Retail - Enhancing the Customer Experience Equipping Sales Associates Tablets/iPads Product Information Product Availability (in store, online) POS

7 Improving The Bottom Line Inventory Via WiFi Scanners Track Customer Movements Through Store Mannequins with beaconing chips How many come in? Where do they go? How long do they stay? How long are check out lines? Targeted Advertising Special Offers Customers who scanned this also scanned.

8 Privacy Concerns a Federal Matter? Location Privacy Protection Act Senator Al Franken Federal Trade Commission Investigation Request Senator Chuck Schumer

10 Implications for Healthcare Deployments Building Construction Old vs New Unique Characteristics 2.4 Ghz vs 5.8 Ghz Design Implications Capacity Interference

11 Implications for Healthcare Deployments Voice Areas of Coverage Signal Strength Signal to Noise Ratio Power Symmetry

12 The Enterprise BYOD/Mobility Implications What devices do you need to support? How much access you will give employees? What kind of budget can you allocate? Do you have specific issues and regulations to contend with?

13 Enterprise Implications Building Types Office/Cubicle Farms Office Building with Neighbors (Rogues) Warehouses Manufacturing Facilities

20 Design Tools Airmagnet & Ekahau Active and Passive Surveys Verify Laptop Specifications Multiple Adapters Check Before You Buy! Multiple Radio/Antennae Models Multi-Floor Data Reporting Reports

21 Design Tools When to Model Small, Uncomplicated Spaces Outdoor Coverage (Limited Roof Access) When to Survey Large Installs (mitigate interference) Complex Structures Congested Spaces Voice Applications

22 Design Tools Passive Surveys RF Coverage RF Interference Simulated Results Active Surveys Connection Speed Connection Throughput Packet Statistics

23 Parameters That Matter! Signal Strength Signal to Noise Ratio (SNR) ac requires 36 db SNR for max throughput! Interference Actual Throughput Packet Loss %

24 Chameleon Malware Exploits Access Points Identifies Security Weaknesses of the WiFi Network Captures User Credentials Then Spreads Not Detected by Anti-Virus or Anti-Malware Software!
