The ICI System JPA Exceeds 60 Fire & Police Agencies


If you build it, they will come.  And this is apparently not only true of a farm-field baseball diamond, but also of a regional trunked radio network.  As the ICI System has completed construction of its 12th Regional Cell, the INSB South Bay Regional Radio System, the number of Police and Fire agencies employing the network as their primary mission critical communications platform has reached epic numbers.  There are now more than 22,000 radios affiliated with the ICI System Network.  That equates to thousands of first responders utilizing the ICI System Network in the protection of millions of citizens throughout the region.


The ComNet JPA of the East San Gabriel Valley Expands to 7 Cities

ComNet, the group of six San Gabriel Valley Cities consisting of Azusa, Covina, Glendora, Irwindale, La Verne and West Covina, who formed their JPA as a cell of the ICI System, have added a 7th partner city – Baldwin Park.  We welcome the City of Baldwin Park to our ICI System family!  The ComNet JPA is a member agency that holds a seat on the ICI System JPA Governance Board.


Santa Monica Becomes 9th Governance Board Agency

The City of Santa Monica joined the ICI System JPA as its 9th Governance Board Agency when their system cell came to life in 2017.  The Santa Monica cell provides robust Land Mobile Radio (LMR) coverage and significant capacity to the west most regions of Los Angeles County.


INSB JPA Formed in South Bay Region

The Interoperable Network of the South Bay was formed as a JPA by the cities of El Segundo, Gardena, Hawthorne, Hermosa Beach, Manhattan Beach, Redondo Beach, and Torrance in 2017 and is presently in the construction phase of what will be the 12th ICI System Regional Cell.  Upon its system’s completion, the INSB JPA will assume the 10th seat upon the ICI System JPA Governance Board.  This 6 site trunked radio network cell will provide an abundance of coverage and capacity for the entire south-western portion of the Los Angeles Operational Area.


Recent actions by the LA/LB UASI Approval Authority, coupled with efforts put forth by the Los Angeles Mayor’s Office, have enabled the I-C-I System JPA to compete for funding within the annual Homeland Security Grant processes. After engaging a professional mediator who assessed regional interoperability in great depth and detail, the UASI and our public safety partners in the Los Angeles Region engaged in a concerted effort to attain true interoperability while recognizing the reality of a need to support more than one single system. This resulted in an award of nearly $5 Million in 2014 UASI funds that will take the I-C-I System to the next level. The funds will be used to establish a Santa Monica Cell, expand the Montebello P-25 Cell into Vernon, and enable Glendale to establish a second Master Site to provide full redundancy to the primary I-C-I System core. We look forward to integrating/interfacing with all similar LMR systems in the region and operating as “one” as we move forward with interoperability.


ICISYSTEM.ORG is now replacing our former domain name of ICISRADIO.ORG. Access to the former domain name will forward users to the new site for a period of a few months before it is inactivated.


The Governance Board authorized a migration to the new branding of The I-C-I System as of their February Meeting. Since that time we have been working to implement that change with minimal disruption and confusion. Use of the former ICIS branding has been discontinued. This was done in an effort to distance our branding from the acronyms by which certain subversive groups are known. Welcome to I-C-I. And check out our new logo in the upper left part of this page!


Effective June 1, 2014, the East San Gabriel Valley Regional Communications Network, JPA, has become the eigth member system in our "ICIS system of systems." The ESGVRCN JPA, known as Com-Net, is comprised of the cities of Azusa, Covina, Glendora, Irwindale, La Verne, and West Covina. We welcome these fine cities as our latest members of the ICIS family. The addition of the Com-Net P-25 two-site simulcast system cell in the San Gabriel Valley represents a tremendous increase in system coverage and capacity on a regional basis.

ICIS operates on T-Band spectrum (470-512 MHz) and desires to remain within that same highly robust and effective spectrum range. ICIS urges Congress and the FCC to revisit the T-Band bill (Public Law 112-96/HR3630) and either extend the auction date to a more realistic point in time when an LTE Broadband solution for mission critical LMR communications emerges, or to abolish the legislated mandate altogether. There is presently no alternative spectrum available to replace the T-Band that is in use by countless first responders nationally and the cost of migrating T-Band systems to other existing bands is staggering (in the billions of dollars), far exceeding the potential revenues that may be generated by any auction of the T-Band spectrum itself.

Montebello Attains  P-25 Digital Status Completing the ICI System Migration

The City of Montebello, one of the ICI System's 12 Cells and also one of the original members to have joined the system in 2003 as a Motorola 4.1 network, has competed migration to P-25 Digital.  As the remaining cells had previously been migrated, this opens a new chapter in ICI System history wherein the entire regional network is a single platform operating on P-25 Digital.

In addition to the P-25 migration, Montebello also expanded from 4 to 7 sites and from 8 to 12 channels per repeater.



The ICI System Authority and its more than 60 public safety agency members seek congressional support of HR 451 that calls for the repeal of Section 6103 of Public Law 112-96 that would cause the costly forced migration of public safety agencies away from the T-Band spectrum.  Public safety needs to stay on the T-Band Spectrum.  Stop the bleeding before it starts, support HR 451.



INSB JPA Cell Nears Completion

The cities of El Segundo, Gardena, Hawthorne, Hermosa Beach, Manhattan Beach, Redondo Beach, and Torrance comprise the Interoperable Network of the South Bay.  Their 6 site, 12 channel cell is now completed and in the testing phase. 


We welcome the INSB  as our 10th Governance Board Member and 12th cell in the ICI System's regional network.  This addition quite literally "tops off" the regional structure of the ICI System.
