HISTORY
� Ministry of Transportation, Ontario (MTO) notified that all analogue cellular services to be terminated by November, 2009
� Project initiated to identify all existing applications using analogue cellular and to migrate them to using analogue cellular and to migrate them to new digital cellular services
� At the time, the applications were:
� Portable Variable Message Signs (PVMS)
� Pole Mounted VMS
� Road Weather Information System (RWIS) sites

NEEDS ASSESSMENT
� Thorough review conducted to identify existing
shortcomings of the legacy system:
� Slow communications
� Unreliable communications� Unreliable communications
� Costly for long distance cellular applications
� ie often times there is a significant distance between the
between operator and the actual field device
� Need to have a fast, reliable, secure and cost
effective solution

CONSIDERATIONS
� Investigated the three major service providers
at the time: Bell Mobility, Rogers and Telus
� All three were migrating over to Ethernet over
digital cellulardigital cellular
� Security concern regarding use of public Internet
�Need to have static IPs or else DNS solution
� Bell Mobility at the time, only service provider
offering the IP-VPN solution

IP-VPN SOLUTION
�Ministry has our own separate pool of static IPs on the digital cellular network referred to as a “NAG”
�Modems on this network are assigned a phone number and static IPModems on this network are assigned a phone number and static IP
� Phone number for billing purposes
� Static IP address for communications
� Only modems activated within the NAG can see and communicate each other

CONS TO THE APPROACH
�MTO is now in the ‘modem business’
�Need to act as custodial office for the distribution
of modems to all users (eg contractors)
�Potentially paying twice for modems�Potentially paying twice for modems
� Communications problems with modems now MTO
responsibility
� Fleet management of modem asset now a
consideration

BENEFITS OF THE APPROACH
� Significant cost savings� For many legacy applications MTO was paying upwards of $300/month/modem� Cellular use + Long distance charges
� Estimated provincial savings of over $600K per year in PVMS application aloneapplication alone
� Fast communications� Before 20 mins to put a message on a sign
� Now reduced to seconds
� Reliable communications� Far more reliable than legacy system
� Confirmation that message was sent and displayed

IP-VPN EXPANSION
� Given the business case, system expanded to include communications to:
�Ministry owned, operated traffic signals
�RWISRWIS
� Permanent Data Counting Stations
� Portable CCTV cameras
� Portable Vehicle Detection Systems
� Being given consideration for both mobile and static applications
