• Network that provides the means to access information over a diverse set of wireless and wired networks.

Wireless 101

• Wireless technology differentiated by

• Bandwidth

• Geography

• Device Support

• Switching Method

• Two types of switching methods

• Circuit Switched

Citrix Value Add to Workforce Mobility

Network utilization

• ICA is thin!

• Support for wired and wireless connections - ISDN, DSL, Frame, GSM, GPRS, CDMA, 802.11

• SpeedScreen3 Latency Reduction enhances already thin connectivity

Application management

• Deliver existing applications “as is”

• Rapid deployment/upgrades

Citrix Value Add to Workforce Mobility

Client device

• ICA turns any device into a thin-client

• Support for the latest OS - CE, PocketPC, Symbian

• ICA’s seamless windows enables interaction

between server environment and client peripherals

• Panning and scaling optimizes viewing area for running applications on small-screen devices

Secure Application Access

• Wireless to web security with Secure Gateway & Citrix® MetaFrame® Secure Access Manager

• Strong authentication using smart cards & tokens

Citrix Solutions for Deployment

Deployment Considerations

• _{Identify the target user groups for mobility services}

• _{Define their primary access and application needs}

• _{Select the content and applications that are likely to}

be most successful for those target groups

• _{Define how elements of the mobile ecosystem can}

be combined to deliver a compelling mobile

Citrix Solutions for Deployment

Deployment Considerations

• Evolve/establish your carrier relationship

• Look to your key existing platform partner/provider for mobile solutions

• _{Identify other mobile solution vendors}

• Who else in the organization should participate in these initiatives ?

Develop Mobile Partnering

Citrix Solutions for Deployment

Deployment Considerations

• Determine the technology architecture required to

support the desired mobile user experience

• Potentially select candidates for mobility solutions

piloting or early point solution development

• What is the cost / benefit of various technology

alternatives (e.g. TCO, ROI)?

Optimizing the Experience - Why?

Wireless (wWAN) Technology Limitations

• Network limitations

• Bandwidth & throughput

• Latency: LAN 1mSec, WANs: 100mSec-300mSec, wWAN 300mSec-3000mSec

• Device limitations

• Display size

Optimizing the Experience - Techniques

Objectives

• Improving the user experience

• Reducing the perceived user latency

• Reducing the login time

Optimizing the Experience - Techniques

Mechanisms

• Reducing the maximum ICA packet size

• _{Reducing the number of small packets}

• Using SpeedScreen™3 to reduce perceived latency

• _{Using Caching and compression to}
