Introduction
Introduction

  • Municipal Wireless networks are a hot new topic in the face of telecom today

    • Enhance services to community

    • Over 300 governments have created Municipal Wireless networks

    • Several Reasons for Municipal Wireless Networks

      • Bridge the digital divide

      • Combine government services and public access


Introduction1
Introduction

  • These networks will be owned and managed by many different entities

    • Multi-system Operators (MSOs)

    • Wireless ISPs

    • Phone Companies


Wireless mesh networks
Wireless Mesh Networks

  • Based on 802.11 WiFi

    • Laptops, PDAs, Cell Phones

    • May eventually migrate to WiMAX

  • 8 to 30 WAPs to cover one square mile

    • WAPs use mesh capabilities to bring all network traffic back to a single access point

    • This access point provides the backhaul for all other WAPs

    • Uses DSL, Cable, T1, point-to-point wireless, or WiMAX


Service offerings
Service Offerings

  • Free Public Access

    • Unregistered

    • Registered

  • Flat-Rate Fee-based Public Access

  • Differentiated-Rate Fee-based Public Access

  • Web (URL) Filtering

  • Spectrum Preservation

  • Public Safety

  • Video Surveillance

  • Mobile Government Users


Service offerings cont
Service Offerings (cont.)

  • Virtual Private Network (VPN)

  • Voice over IP (VoIP)

  • Meter Reading

  • Government as Anchor Tenant

  • Dedicated Internet Access


Free internet access unregistered
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
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
Flat-Rate Fee-Based Public Access

  • New requirements emerge with fee-based access

    • Need special billing systems

      • Interact with network and allow access from customer service representatives

      • Limit user bandwidth to what they pay for

      • Need to be aware if users are active and have paid

    • Steel Belted RADIUS sets up Multiservice Edge Router


Differentiated rate fee based public access
Differentiated-Rate Fee-based Public Access

  • Customers receive different charged for different levels of service

    • Users may pay for unlimited usage

    • Users may be limited to a peak information rate

    • Users may be limited to a certain number of bytes of download per day

    • Users 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 filtering
Web Filtering

  • Non-profits and municipalities restrict users from being able to reach certain sites

  • Use of a firewall

    • Blacklist

    • White-list

    • Sites are stored in database


Wireless spectrum preservation
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 network

    • Worms and DoS attacks use up backhaul bandwidth

    • At-risk users

  • Intrusion Detection and Prevention firewalls


Public safety
Public Safety

  • Public Safety communications have high standards to meet

    • These standards have risen over the last five years due to well-known failures of these networks

    • Police, fire, and rescue teams need be given higher priority than other traffic

    • Operators need to be able to control the access rate that devices send traffic onto the network


Video surveillance
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 users
Mobile Government Users

  • Spend significant amount of time traveling to locations throughout the municipality

    • Inspectors

    • Building Inspectors

    • DPW employees

  • Need security due to dealing with public trust data

  • Odyssey Client on user laptop for security

  • Steel-Belted RADIUS


Voice over ip voip
Voice over IP (VoIP)

  • Two categories:

    • Calls conducted with the network and network operator’s knowledge

      • Skype

      • Vonage

    • Calls conducted without the network and network operator’s knowledge


Meter reading
Meter Reading

  • Currently labor-intensive

  • Water and electric meters

  • Traffic monitoring

    • Speeding Tickets

    • Red light tickets

  • Handheld devices can transmit tickets, public safety inspection reports and other government forms


Government as anchor tenant
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
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
Advanced Network Services

  • Operators will want to introduce new, advanced services after initial deployment

  • Operators will want to sell these new services
