IntroductionMunicipal Wireless networks are a hot new topic in the face of telecom today
Enhance services to communityOver 300 governments have created Municipal Wireless networksSeveral Reasons for Municipal Wireless Networks
Bridge the digital divideCombine government services and public access
IntroductionThese networks will be owned and managed by many different entities
Multi-system Operators (MSOs)Wireless ISPsPhone Companies
Wireless Mesh Networks
Based on 802.11 WiFiLaptops, PDAs, Cell PhonesMay eventually migrate to WiMAX
8 to 30 WAPs to cover one square mileWAPs use mesh capabilities to bring all network traffic back to a single access pointThis access point provides the backhaul for all other WAPsUses DSL, Cable, T1, point-to-point wireless, or WiMAX

Dedicated Internet Access
Free Internet Access (Unregistered)
Free Internet Access
Roaming capability of mesh networks allows for users to move between access points
A stationary device may seek out the best possible connection
Free Internet Access (Registered)
Requires RADIUS server to authenticate users
Standards-based Authentication, Authorization, and Accounting (AAA)
Juniper Networks Steel Belted RADIUS server is deployed to ensure use by only registered users
Flat-Rate Fee-Based Public Access
New requirements emerge with fee-based access
Need special billing systemsInteract with network and allow access from customer service representativesLimit user bandwidth to what they pay forNeed to be aware if users are active and have paid
Steel Belted RADIUS sets up Multiservice Edge Router
Differentiated-Rate Fee-based Public Access
Customers receive different charged for different levels of service
Users may pay for unlimited usageUsers may be limited to a peak information rateUsers may be limited to a certain number of bytes of download per dayUsers may be guaranteed a minimum information rate or any of a number of QoS Parameters
It is possible a user’s payments are not current and need to be restricted from the network
Web FilteringNon-profits and municipalities restrict users from being able to reach certain sites
Use of a firewallBlacklistWhite-listSites are stored in database
Wireless Spectrum Preservation
Each WAP has a limited amount of bandwidth
With the success of adding users, the network will become more constrained
Operators will place control on several types of users
Abusive users must be prevented from placing malicious traffic into the networkWorms and DoS attacks use up backhaul bandwidthAt-risk users
Intrusion Detection and Prevention firewalls
Public SafetyPublic Safety communications have high standards to meet
These standards have risen over the last five years due to well-known failures of these networksPolice, fire, and rescue teams need be given higher priority than other trafficOperators need to be able to control the access rate that devices send traffic onto the network
Video Surveillance
Presence of cameras can be a crime deterrent and storage of video helps ensure convictions
Video cameras can monitor traffic
Video at special events can be quickly arranged with a WiFi connection
QoS parameters must prioritize video data
Ability for operators to increase bandwidth to a certain camera to increase quality
Mobile Government
UsersSpend significant amount of time traveling to locations throughout the municipality
InspectorsBuilding InspectorsDPW employees
Need security due to dealing with public trust data
Odyssey Client on user laptop for security
Steel-Belted RADIUS
Voice over IP (VoIP)
Two categories:Calls conducted with the network and network operator’s knowledge
SkypeVonage
Calls conducted without the network and network operator’s knowledge
Meter ReadingCurrently labor-intensive
Water and electric meters
Traffic monitoringSpeeding TicketsRed light tickets
Handheld devices can transmit tickets, public safety inspection reports and other government forms
Government as Anchor Tenant
Key to overall success of Municipal Wireless Network
Government is very large with significant telecom needs
Allows for fiscal security
Dedicated Internet Access
Bridging the digital divide
Serve the Small/Medium Business (SMB) Market
MSOs, telcos, and wireless ISPs are trying to expand customer base
SMBs only need firewalls and LANs
Advanced Network Services
Operators will want to introduce new, advanced services after initial deployment
Operators will want to sell these new services
