Background
• Population
56,840 (likely to double in 5 years with
annexations)
• Geographic
17.85 miles
City center sits in a valley with plateaus on
either side, on the southeast side of Seattle.
Lots of trees!
• Economic
Economically vibrant with a doubling of
property values in 10 years and annual growth
in sales tax revenues of 18.5% over the last 5
years
• Regulatory
Incorporated in 1901, strong mayor form
Project History
• 1998 - Began exploring high speed data options for public
safety use
• 2002/2003 - Three pilot projects run and managed by the IS
staff
• 2003 - Demo to city council in 2003 comparing 802.11b and
RDLAP.
• 2004 - Mayor & Council authorized building coverage across
80% of the city with $500,000 in capital funding. Funding
level now @ $750,00 as more vehicle and hot spots continue
to be added. Free use to the public.
• 2006 - Project complete, well not really….
Project Objectives
• Provide a rich set of desktop services in the
patrol vehicle
• Increase officer productivity & effectiveness
• Improve community policing
• Better data availability to on scene incident
commanders
• Contribute to community economic
development efforts
• Provide surplus bandwidth for public use
Business Model
• Designed as an extension of the city’s wired network, the
business model is to provide the same level of robust
service delivery we would provide to a desk bound
customer.
• Targeted users:
– Police/Fire first responders
– Inspectors, public works maintenance crews, parks, etc.
– Surplus bandwidth for public use
Project Economics
• Cost structure:
– Startup Costs
– Annual Capital Costs
– Staffing
$500,000
$100,000
¾ FTE
• Funding Sources
– Annual Capital Fund Investment
• Return on Investment
– Not calculated
• Sustainability and Scalability of the project
– Discreet network segments provide future flexibility
– Technology has become infinitely scalable
Applications
• Current applications

Police Records Management
Fire Records Management
Remote Field Reporting (police/fire)
Fire inspections
Real-time water valve, hydrant & meter data access
Park’s irrigation management
Emergency Management Resources
• Future/ Potential applications
– Real-time maintenance task management
– Real-time GIS access for asset management
Wireless Project Challenges
• 2.4 GHz is an unregulated spectrum
(F.C.C. just doesn’t care!)
• Frequency Crowding (Spectrum
Utilization)
• Topology
• Siting (Where do we have acceptable
antenna locations?)
• Power (Is it available, UPS, gen
set…?)
• Backhaul Capabilities (or how do you
get the packets back to your network?)
• What is a warm zone?
Project Scope
• 9 Servers (providing
security/authentication services)
•
•
•
•
30 network switches
39 outdoor access points
34 indoor access points
68 mobile RMARS (Renton
Mobile Access Radios)
Coverage Map
What does our public segment look like?
Next Steps?
• Clear statement and regional agreement as to the goals & objectives for a
regional wireless network.
• Consolidation of effort
– King County Police Chief’s Association Initiative
– Valley Communications non-owner Agency Initiative
– Valley Mayor’s Initiative
•

•
•
•
What are the expectations of business & other community stakeholders?
Potential economic benefits?
Does this address the digital divide issue?
Does this improve delivery of government services?
What would a regional wireless network look like (i.e. ISP services, free,
compete with commercial interests, public safety impacts, etc.).
Regional
Wireless Project Challenges
•
•
•
•
•
•
•
•
Public Safety must be on a regulated spectrum?
Regulated spectrum means proprietary solution?
Regulated spectrum means a lot more project $$$
Regulated spectrum
may mean limited
public access using
“standards based”
equipment or
Separate public
safety & public
access networks
Security standards
Management &
Governance Issues
Capital &
Maintenance Funding
Potential Regional
Wireless Project Issues
•
Security Issues
– Public Use
– Separate traffic from trusted network (dedicated vs. same infrastructure)
•
Managed vs. Unmanaged

•
Municipal vs. Multi-jurisdictional

The Future of Wireless Technology
• Every major player in this market space is looking at the next generation.
– 100MB wireless is already running in labs & some equipment is out.
• Cell phones now population 8 out of 10 families (new land line installs
have dropped and existing numbers are down).
• Chicago to install 7,500 access points ($18M).
• TowerStream, in NY, sells wireless T1 circuits for $500 per month.
• Long-time infrastructure providers have consolidaed around wireless.
– Sprint (owned by MCI) buys Nextel.
– Qwest & Verizon fight over MCI. Verizon wins.
– Cingular buys AT&T Wireless.
• Wi-Max, what is it, where is it?
