3
Wireless in Transition
The basic deployment of wireless technologies
will follow directions that are typically
mutually exclusive.
4
Service Deployment
The basic deployment strategy is driven by a
composite set of general public and
departmental specific functional need
assessments
5
Policy Development/Enforcement
Regardless of the deployment strategy,
comprehensive policies and enforcement directives
will be needed to control the emerging wireless
environment.
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.
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.
8
Security
Access to the networkand access to the
database are often conflicting scenarios. The
goal is to deploy a system that protects both.

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

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

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.
