Agenda Evolution of WLAN Benefits of Distributed architecture Next Generation Verticals – BOYD, 3G offload Wireless Security Voice over WLAN – Push to talk, Switch based  telephony. • Integrating two way radios with WLAN • Case study on WLAN at the China Olympics

• • • • •

The Evolution: In the beginning •

Access points required to provide network intelligence for WLAN requirements

•

Access Points are deployed “passed the edge”

•

Layer 2 device

•

Resulting in unnecessary costs for:   

BYOD – COLLISION OF TWO WORLDS Personal Devices Corporate World

Open Networks Highly Secure Low Visibility High Infrastructure visibility Limited Anti-virus Corporate Access Personal Antivirus ProtectionEmails

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 consumption per user on a global basis will  increase from 1GB in 2009 to over 14GB in  2015

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 

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

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
