DEVICE TRENDS Are employees allowed to use their own devices? Source: Quocirca - Sept 2011
BYOD COLLISION OF TWO WORLDS Corporate Personal Devices World Highly Secure Open Networks High Infrastructure visibility Low Visibility Corporate Limited Access Anti-virus Antivirus Protection Personal Emails
What is a BYOD solution requirement? IT departments should be able to provision personal devices of enterprise employees in a non intrusive manner Provide Enterprises with Tools to self provision devices by the employees themselves Typically a Captive Portal with Open security permits first entry. The BYOD platform then provisions the device with Anti Virus, Personal Firewalls, Certificates to then permit the device on the corporate network.
Another Emerging Vertical: 3G offload Current Situation Carrier Need 3G/cellular data traffic greater than expected at highly concentrated and nomadic areas Smartphones doing internet surfing, video streaming, music download Consuming massive bandwidth Smartphone share growing rapidly Potential lost revenue on customers with usage based pricing Customer satisfaction and network performance issues. 4G rollout may take a while and may still not be enough. Carriers need a way to handle the load
Data Growth 30 Data Traffic Data Revenue 30 Data consumption per user on a global basis will increase from 1GB in 2009 to over 14GB in 2015 Data Traffic (normalized to 2009 volume) 25 20 15 10 5 25 20 15 10 5 Data Revenue (normalized to 2009 USD) Mobile data traffic doubling every year through 2013 growing 100 times faster than mobile data revenues Data revenues remain relatively constant creating wide gap data traffic 0 0 2008 2009 2010 2011 2012 2013 2014 2015 Source: Yankee Group 2009
Video The new Cell Edge Traditional Cellular Network Architectures, designed for Voice, are now two decades old. 90% of all IP traffic will be Video by 2013 64% of all Mobile IP traffic will be Video by 2013 Cisco Visual Networking Index: Forecast and Methodology, 2008 2013 Voice & SMS: 30 Kpbs Cell Radius: 1 Km+ Current estimates suggest that video will be the single largest component of mobile data usage Streaming Video: 600 kbps~1.5 Mbps Cell Radius: 300 ~ 500 meters
Carrier Business Case 3G WiFi Typical add on 3G/4G Site Cost Hotspot Solutions Available now Off-load heavy Fixed/Nomadic users from Mobile network Create bridge to 3G or 4G Preserves high value mobile spectrum and infrastructure for high ARPU Customers Applies to all mobile markets: HSDPA, WiMAX, LTE et al. WiFi off load $$ = 3-4% add-on to full site Mobile network cost Deploy WLAN where required Hotspot Average Cost: $1000s per hotspot 3G/4G Site: $10,000s per site for equipment, installation, site fee, etc.
Wireless Security Breaches Cost Millions Average Cost for each compromised record: USD 300 - Gartner 10s of Millions of Credit Card records have been breached in the past few years Average Breach Cost is $6.6m (Network World) What does this have to do with Wireless? Attacks are No Longer Innocent Attempts to Gain Notoriety Organized Crime Uses Wireless Hacking to Steal Money

Simple PTT Voice Communications IMPROVE ASSOCIATE PRODUCTIVITY THROUGH ENTRY LEVEL VOICE COMMUNICATIONS Should be a Wearable, industrial grade solution Cost effective so can justify deployment for all associates Must be easy to use The communicator should be designed to work on a single subnet for small groups of users Create multiple groups Should have private call back feature
RADIO LINK SYSTEM OVERVIEW Mobile Extension Talk Group 1 Radio Link provides PTT talk-group communication between the Mobile Extentsion solution and a two-way radio solution. Two-way Talk Group 1 AP RIU Two-way Donors Mobile Extension Talk Group 2 Appliance with Radio Link Two-way Talk Group 2 Enterprise Network PTT talk-groups are established between the Mobile Extension talk groups and two-way radio talk groups by utilizing a two-way mobile radio "donor" device. Each talk-group requires a dedicated two-way donor mobile radio which is connected to the Radio Link via the Radio Interface Unit (RIU).. Each RIU can accommodate up to 4* talk groups. The Radio Link application utilizes the appliance hardware
