Delaware County Council unanimously approved funding for the necessary upgrade of the County's emergency communications system at its August 17 public meeting.

With this first major radio upgrade since the 1970s, the County will deploy new, higher frequency radios, expand the coverage area, and increase reliability and coordination among First Responders. The three-year upgrade, which includes moving the County's system to a 700 MHz radio spectrum and the purchase of 3,700 new radios, will increase the ability of various agencies to communicate and work together.

The upgrade will cost approximately $38 million, a significant discount below the initial estimate. The upgrade will be completed by JVC Kenwood and follows an extensive review of various design approaches and products that took place beginning in 2021.

"An integral piece of our commitment to the public's safety is ensuring that First Responders across the county have the tools and resources they need to communicate with each other in real-time in order to effectively respond to crises and deploy critically needed emergency services," said Delaware County Councilman Kevin Madden. "This investment in upgrading our Public Safety Radio System will have an immediate effect and help keep our First Responders safe and allow them to more effectively work together to protect the public."

The upgrade will increase the capacity of the County's emergency system and its reliability by moving from a 500 MHz radio spectrum to 700 MHz, increasing the security of the system to prevent hacking, and purchasing and distributing 3,700 radios to ensure that first responders have access to the system's capabilities and features. The improved system does not require new towers to be built and will utilize the 20 radio transmission towers. Local governments will also have the opportunity to purchase new radios at a significantly reduced price under this contract.

Council’s vote to authorize the upgrade followed research and feedback from First Responders across the county. In 2019, Council commissioned a study of the needs of First Responders and the capabilities of Delaware County’s current radio system following reports that there had been multiple situations when emergency personnel could not reach the 911 system due to problems related to the use of lower 500 HMZ frequency radios. The radios that relied on older technology sometimes experienced a problem referred to as Troposphere Propagation (also known as ducting) occasionally interfering with the ability of a First Responder to communicate with the 911 Center. The new radios will utilize updated technology and new frequencies that should reduce interference issues.

“Council commends the Department of Emergency Services, under the leadership of Director Timothy Boyce and project consultants ACD Telecom and JVC Kenwood for their diligence in improving service and reliability across the county,” said Madden. “Council has always been and will remain committed to ensuring that we are careful stewards of taxpayer money, even as we make critical and long-overdue investments in our county and its future."

Now that the announcement is official, I am excited to discuss some of the parts of this project.

JVCKenwood is a subsidiary of EFJohnson. The Atlas P25 system is the system that was selected for Delaware County after multiple years of planning and engineering. There was a full bid process completed which started in mid 2021 and completed in the early part of 2022.

The Delaware County P25 Phase 2 system will include 20 sites configured as a single simulcast cell countywide operating in 700Mhz. The County requirements for the system call for 97% portable coverage countywide at a minimum DAQ of no less then 3.4. These requirements assume portable radio mounted on the responders hip with the antenna attached to the portable.

The Atlas system is known for its ability to function using distributed architecture. Those that are familiar with P25 trunking systems will understand the terminology "core" and "Master/Prime/simulcast controller". There are no cores, and there is no master/prime simulcast controller with the Atlas infrastructure. Each individual site in the TRS holds a full copy of all data necessary to function as a full trunking controller, subscriber database, system controller, and simulcast controller. This allows for the system to continue to function and form new cells in the event of a catastrophic break of the network ring. Example: Sites 1 through 10 become disjointed from sites 11 through 20. In this scenario, Atlas will essentially form 2 separate simulcast cells (1 through 10 and 11 through 20) allowing for multisite simulcast trunking in each of the cells since there is no core and no master simulcast controller to worry about.

The selected subscriber is the Viking VP8000 Multi-Protocol, Multi-Band portable radio. Protocols included will be P25 and DMR. This is the first Multi-Band, Multi-Protocol radio available and was just released. As many in the Delaware County area are aware, there are many individual private systems used by school districts, higher education facilities, municipal services Etc. These systems are, in many cases DMR systems that police and fire departments have access to today for direct communication with staff at these facilities when needed. Several colleges and universities exist in Delaware County. In most of those situations the schools public safety and staff are operating on DMR systems. These multi-protocol portable radios will allow the responders to have direct access to these schools radio systems using the same portable radio that will give them access to the P25 Phase 2 system. Nobody wants to hear that they are losing something that they already have. The VP8000 allows officers to retain the ability to access the legacy UHF DMR systems in the same radio being used for the new County TRS.

I have attached a case study for those not familiar with the Atlas system and how the nature of the distributed architecture of the Atlas system allowed for it to remain operational with wide area trunking after Maria and Irma devastated Puerto Rico.

Hopefully the powers to be will NOT encrypt the police sector dispatch channels.. They will have many options to choose from in the way of several talk groups such as tac, cid, or whatever they choose to call them when they set up a programming template and they can be strapped ENC.

I'm hoping that whatever is decided, thought is put into it and things aren't done just because it is the current "fad" There is a great opportunity here to improve emergency communications for police, fire, ems, and fire police. Unfortunately in todays world some communications need to extra security so I am sure encryption maybe used on some TG's every modern system has that. As long as they include and get input from all of the different disciplines that are using the system, there should be little issue. I am looking forward to they system having less rouge radios on it and the better control over the authorized users.

There is also an Atlas P25 system being installed in Frederick County VA which was recommended by Mission Critical Partners. There is some controversy surrounding the award, particularly from L3/Harris (Virginia is L3/Harris' "backyard") in terms of overall system cost. The proprietary technology used in the Atlas system infrastructure and the P25/DMR subscriber units is going to limit equipment selection in the future. Delco is the largest jurisdiction to date that will be using Atlas AFAIK - it's will be an interesting risk to manage.

Been watching the Frederick project for a long time as well. Was happy to see the work they put in to their selection there. Not sure of their exact configuration down there but what will be deployed in Delaware County is about as non proprietary as it gets. There would be nothing stopping an organization from buying a Motorola, Harris, Tait, or any other P25 Phase 2 capable subscriber and placing it on the system in the future.

The key is not using proprietary features. All radios will have standard AES capabilities for any talkgroups that encryption is decided to be used on. No proprietary encryption types. The goal is to be as non proprietary as possible.

As far as the DMR in the VP8000 goes, it is not a requirement to have in a subscriber in order to use the system. It is just a feature in the subscriber to allow users to use other non county systems that they may be using already today. Users wouldn't be required to have a DMR capable radio if they were buying their own equipment.

IDK, the ability to have P25/DMR in the same subscriber was a "selling point" for both the interim system / future backup system, as well as a route to interoperability. However, it is true that P25-only subscribers would be able to live on the system, minus any feature set specifically enabled by Atlas / EFJohnson / Kenwood software or equipment.

Nice to see a government agency actually doing their research. Anyone not going with, or at least looking heavily into, one of the distributed architectures such as Atlas is doing themselves a disservice. Wish I was closer to see this come online.

It really depends on the regional operating environment to decide what network structure works best. An Atlas system would not be a good fit in the NCR region (mostly Moto Astro P25) where inter-jurisdictional response is routine and system-to-system links are common - and in some cases, georedundant prime sites. This is where the system consultants are extremely important because they are not tied to any one vendor (or should not be, ahem.)

The whole point of ISSI is to link P25 system regardless of manufacturer, so I'm not sure why you think an Atlas or Vida or any non-ASTRO 25 system would be a roadblock to connectivity/interoperability in any given region. Also not sure what georedundant core/prime site has to do with the day to day operation of a system, or what impact it has on subscribers (none).

Seems like you're conflating some of these features with things that actually matter to the users of the system. Most don't, and are completely transparent to subscribers. As long as the system follows the P25 standard and isn't heavily laced with proprietary features, it's not going to really make much difference whose logo is on the hardware.

Let's start making bets on Encryption. I have $100 on them encrypting police dispatch and tac channels. Any takers?

ISSI doesn't always work well across manufacturer's equipment. There's a reason why WMATA's regional / overlay system in the NCR is being built by Motorola and not by L3/Harris or EFJohnson - it's a better fit with the existing systems in the region. Coincidentally, V-COMM is the system consultant for both Delco and WMATA.

Can you cite any specific documented cases from reliable sources, or is this based solely on anecdotes you've read on the internet?

Oh I'm sure there's a "reason" why they're also going with MSI, but it's probably not the reason you think it is.

Here's why (from the NCR LMR Strategic Plan):

"The primary benefit of ISSI is that the technology adapts very well to the current communications system environment within the NCR. The solution will leverage existing P25 systems already purchased and existing backhaul networks. The flexible nature of the solution will enable each agency to maintain the complete autonomy of their network infrastructure, and tightly control the level of roaming to ensure capacity is maintained on primary networks. Adapting to the capabilities provided by ISSI will provide the region a long-term migrating path to implement shared system solutions. Implementing ISSI will require existing Motorola P25 networks to be a system release level 7.13 or later. Several jurisdictions within the NCR are either already at release level 7.13 or have plans to be at 7.13 or a more current release within the next two years. Jurisdictions with legacy systems will be purchasing P25 systems in the near future, and will be at the current system release offered by their system vendor. The additional costs associated with the implementation of ISSI include the purchase of an ISSI gateway by each jurisdiction, licensing ISSI roaming capabilities through the equipment vendor, and establishing backhaul connectivity through NCRNet. Subscriber flash upgrades to add ISSI roaming software and talkgroup modifications will be required for most jurisdictions."

All NCR jurisdictions now operate Motorola P25 trunking systems, excepting Charles County which is in the process of upgrading their SmartZone to Astro P25. WMATA plans to use their new 700 system both operationally and as an overlay network for the region.

Where Delco sits we have Harris to the west, Moto to the north, and moto to the east. ISSI does work well as far as connecting systems together for system to system voice. Where it gets a bit troublesome is when true roaming is configured between between the systems on ISSI meaning TG1 in Delco becomes available on the CHESCO Harris system because a user roamed in to the CHESCO coverage area. The reason that this is sometimes problematic is because the feature sets have to be very similar in order for the system that is roamed to to be usable. The other issue is you are now sharing your systems resources including available trunking channels with an agency that may or may not actually be operating in your county. This is all configurable but in most cases if a unit needs to switch to a neighboring system they are going to switch to that system on the radio.

By the way, ISSI with the Atlas package is a very simple metric. No licenses per connection. The ISSI gateway included with the Atlas system will do up to 24 ISSI connections to distant systems. No licenses needed on the Atlas side.

Also, to clear any confusion. The consultant for the bid process is ACD Telecom. VCOMM was the consultant for the original needs assessment.
