Slide 1: Wireless Directions University of California, Davis Wireless Technology Team February, 2001
Slide 2: Market View Market Acceptance 12-24 Months Market Trigger Expectations Reality Check Demonstration of Value Productivity Time in the Market Place February, 2001 UC Davis Wireless Evaluation Team 2
Slide 3: Wireless in Transition The basic deployment of wireless technologies will follow directions that are typically mutually exclusive. Control Centralized Decentralized Comprehensive Favors exposure to the widest possible set of campus users Cannot achieve Coverage Specific Areas Always possible •Favors unique solutions •May interfere with public areas •May exclude Instructional areas February, 2001 UC Davis Wireless Evaluation Team 3
Slide 4: Service Deployment The basic deployment strategy is driven by a composite set of “general public” and “departmental specific” functional need assessments Comprehensive Control Centralized Decentralized ⇑Uniform Service Model ⇑Aggregation of Demand ⇑Standardized Interfaces ⇑Minimized Interference Cannot achieve Coverage ⇑Public areas covered ⇑Managed incremental growth ⇑Greatest coverage to the largest user base at the least cost ⇓Client irritation Specific Areas ⇑Department defines coverage ⇓No Standardized Interface ⇓Interdepartmental Interference likely ⇔Dept. Managed Service Model ⇓No common funding or Support models February, 2001 UC Davis Wireless Evaluation Team 4
Slide 5: Policy Development/Enforcement Regardless of the deployment strategy, comprehensive policies and enforcement directives will be needed to control the emerging wireless environment. Comprehensive Control Centralized ⇑ Standard Access policies ⇑ Standard hardware & software policies ⇑ Central monitoring of use ⇑ Central Interference policy ⇑ Campus wide funding model Decentralized Cannot achieve Coverage ⇑ Limited areas are easier to monitor ⇑ Less interference issues ⇑ Less robust funding model required ⇑ High flexibility on use Specific Areas policies ⇔ Dept control of access ⇓ Dept control of hardware & software ⇓ Dept control of interference issues ⇓ Dept control of funding February, 2001 UC Davis Wireless Evaluation Team 5
Slide 6: Business Risk Business risks affect every aspect of the final strategy. Of key importance to the institution is the ability to meet the increasing sophistication of our wireless constituents. Comprehensive Control Centralized ⇑ High Level of Decentralized Coverage expertise available to campus ⇑ Integration with other campus core systems ⇑ Standardized repair and maintenance ⇑ Regular refresh ⇑ Fewer locations mean Cannot achieve Specific Areas lower integration costs ⇑ Lower training and maintenance costs for equipment ⇑ Lower cost to exit into newer technologies ⇑ Depts. develop in-house expertise ⇓ Integration only with dept specific systems ⇓ Increased risk of obsolescence ⇓ Multiple vendors/systems cause higher cost of ownership for campus as a whole.

Slide 7: Conformance To Standards The University has found it necessary to define a comprehensive set of technical and “acceptable use” policies governing existing core telecommunications services. Adding wireless services to the existing mix will require development and adherence to new standards. Comprehensive Control Centralized Economies of scale ⇑ Lower training and operational costs ⇑ Easiest to monitor for conformance ⇑ Decentralized Cannot achieve Coverage Common standards maintained ⇑ Standard systems available on demand ⇑ Simplified technical and functional requirements ⇑ ⇓ Departments define and Specific Areas implement all access and use guidelines ⇑ Highest focus on unique needs ⇓ Must address frequency interference issues February, 2001 UC Davis Wireless Evaluation Team 7
Slide 8: Security Access to “the network”and access to “the database” are often conflicting scenarios. The goal is to deploy a system that protects both. Comprehensive Control Centralized Parallels existing core systems ⇑ Easiest to manage ⇑ Common policy enforcement ⇑ Minimizes service loss impact ⇑ ⇓ Decentralized Cannot achieve Coverage Common policy enforcement ⇑ Access across geographical boundaries ⇑ Specific Areas Security varies by department ⇓ Individual user irritation moving between areas ⇓ Support and compatibility issues February, 2001 UC Davis Wireless Evaluation Team 8
Slide 9: Management Issues Centralization The ability of the campus to identify,track, and manage a single seamless wireless system is maximized Single accountability for design and deployment assures adherence to standards Total costs can be identified and managed in unison with other campus core telecommunications services Focus on broadest set of constituent needs may limit departmental depth of feature selection and use  Decentralization Systems can be rapidly deployed based on departmental initiative Systems will reflect departmental functional requirements Deployed systems are likely, almost assured, to cause interference without a central design strategy Policies will need to be developed to mitigate inevitable issues of frequency interference Total cost of ownership will be invisible to senior campus management  February, 2001 UC Davis Wireless Evaluation Team 9
Slide 10: Funding Impacts         Budgetary impact $10.5M (based on known $1.50/square foot from Cisco/Microsoft) Approximate client base capability 20,000 to 40,000 based on $250 - $500 per user macro cost from Ericsson and Alcatel Does not eliminate wired support Additional personnel for design and support Existing servers may need upgrades and/or significant configuration changes May impact existing campus technology funding models Will require new funding and billing models Changes in technology could obsolete the investment overnight February, 2001 UC Davis Wireless Evaluation Team 10
Slide 11: Directions Control Centralized Comprehensive Coverage Decentralized Comprehensive 2002/2004 Coverage 2001/2002 Public Areas concurrent Specific Areas 2001/2002 Departmental & Instructional Areas February, 2001 UC Davis Wireless Evaluation Team 11
Slide 12: Looking Forward      What is driving wireless deployments today? What is the most cost effective deployment method for the campus as a whole? How does the campus take responsibility for the technical obsolescence issues? There are serious issues when comparing the technical characteristics of “shared” vs. “switched” data access. With the requirement that UC Davis students have a computer, we expect to see a dramatic increase in demand for wireless access that is not aligned with departmental requirements.
