Fire Departments in Alberta are facing some interesting times on the communications and dispatch front. Since the Province gave Emergency Medical Services(EMS) an official home within the Healthcare system, EMS has steadily consolidated dispatch services and radio communications to todays three major EMS Dispatch Centers (with a few remaining contracted sites). Not surprisingly these centers are specializing in EMS dispatch, and avoiding or divesting of Fire Dispatch roles. With the loss of EMS Dispatch functions, some local dispatch vendors are struggling to survive on Fire Department call volumes alone.
The much heralded provincial P25, 700 mHz, First Responder Radio System (AFRRCS) is making progress, but remains a few years away from completion. Many Fire Departments are now facing an uncertain future with reference to their dispatch providers, combined with a reluctance to invest heavily in infrastructure (understandibly) with AFRRCS ‘coming soon!’
So, what to do?
Well, if the current system is working, stay the course! But that’s not the case for many services. Facing a need to change dispatch providers, or move off shared radio infrastructure, many departments have no choice but to do something today, but what?
I think on it’s most basic level, the principles need to be:
- Meet todays need (and the need for the next 3-5 years);
- Maximize investment protection;
- Ensure your plan leaves maximal flexibility on when and how to adopt components of the AFRRCS system.
So what I often hear is, “so we should buy a 700 mHz system today right?” Well no, I don’t think so. And why not? In a word, Interoperability! Going it alone for the next few years in the 700 mHz band means no more talking to your friends and neighbors. I can’t recommend that. The second reason I’ll give is cost. 700 mHz hardware is currently substantially more expensive than comparable VHF or UHF infrastructure.
“So we should at least get dual-band, right?” Again, I’d argue this is cost prohibitive, and unnecessary at this stage. Dual-band radios are running anywhere from 3 to 6 times the cost of a comparable VHF/UHF model. We are hopefull that with the increased demand in this band with the AFRRCS system, costs will come down, so I say, wait it out.
The consolidation of EMS Dispatch has resulted in a consolidation of Fire Dispatch services as well. There are some obvious benefits to this consolidation, but some very real challenges as well. Increasing distances not only make our historical RF solutions cost-prohibitive, but too slow for many applications. Radio over IP can address this issue, but must be designed and implemented well, or you’ll be plagued with issues. Satellite based solutions offer great coverage and reliability, but can be cost-prohibitive. Public solutions such as iDEN are tempting, but a risky venture for protective services. So, what to do?
In the most common scenario I’m seeing (need to connect with a new, distant Dispatch Provider), here’s my suggestions:
- Address local RF Infrastructure where needed. Only replace hardware where needed (lack of coverage, nearing end-of-life) Tie radio back to single point within your service area.
- Combine your radios to a single net, and route a single stream over IP to your dispatch provider.
- If you’re fortunate, your dispatch provider has some IP solutions in place. In this case, tie in to their solution.
- A well designed solution will utilize a readily available, low cost IP network for primary connectivity, with a true redundant backup pathway available.
- The IP connectivity should be established and maintained either within a single managed network, or if across multiple ISPs (most common) using Virtual Private Network (VPN) hardware.
- If you need to go it alone on the IP front, here’s some pointers:
- (shameless self-promotion aside) Find someone with expertise in RoIP systems, and Emergency Services Communications. Your friendly neighborhood radio vendor may not have the expertise and experience in this field, and there are many hazards to be wary of.
- Route your networks through a VPN system. This will increase the security and reliability of your connections.
- Networks go down. Look for true redundancy. (I’ll talk about this more another time, but suffice it to say, two cables running side-by-side through a common ditch, are not truly redundant, as one backhoe can kill them both simultaneously). Look at redundancy in provider, technology, and geographic dispersement. This is where I love satellite – you can’t get much more geographically dispersed than that!
- Monitor your connections! As I talk about in ‘Surprise the Radio is down’, IP connectivity should be monitored.
So, how does this stack up with the goals?
- Meeting today’s (and next 3-5 years) needs. Check! Connects reliably to dispatch provider of your choice, and addresses any local RF needs as required.
- Maximize investment protection. Check! First, we maintain as many components of the existing system as are usable (frequencies, system hardware, end-user hardware), limiting todays spend. Secondly, we invest in technology which will help us integrate with the AFRRCS system when it’s on line. (see point 3)
- By linking your current RF system into a single net for IP routing to dispatch, you invest in some interoperability / IP technology which will allow a staged AFRRCS adoption while maintaining maximal interoperability. If you’re not likely to have the budget to do a wholesale switch to 700 mHz P25 devices, but would look at a phased in adoption as devices reach end-of-life, this approach can allow you to have users on your legacy system and users on AFRRCS, and maintain interoperability.
Yes, some challenging times for Fire Departments in Alberta, but reasonable solutions are there, available, and even deployed in some places for your review! As always, your thoughts, ideas, and comments are welcomed!
