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: Equipment Support Upgrade

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 offloadCurrent Situation ‐ Carrier Need

Smartphones doing internet surfing, video streaming, music download

• Consuming massive bandwidth

• Smartphone share growing rapidly

3G/cellular data traffic greater than expected at highly concentrated and nomadic areas

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

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

Traditional Cellular Network Architectures, designed for Voice, are now two decades old.

Carrier Business Case‐3G‐WiFi

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

Typical add on 3G/4G Site Cost

3G/4G Site: $10,000s per site for equipment, installation, site fee, etc.

Wireless Security

Attacks are No Longer Innocent Attempts to Gain Notoriety –Organized Crime Uses Wireless Hacking to Steal Money

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)

Simple PTT 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

Two-way Talk Group 1

Two-way Talk Group 2

• 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.

Radio Link provides PTT talk-group communication between the Mobile Extentsion solution and a two-way radio solution.

• The Radio Link application utilizes the appliance hardware
