The City of Chicago hereby requests 180-day Emergency Special Temporary Authority for the operation of the below described systems/channels to provide the necessary RF linkage between existing City operations and the Statewide interoperability initiative employing the Astro 21 system and those channels being deployed as a portion of the U.S. Department of Justice's High-Risk Metropolitan Area Interoperability Assistance Project. In essence, the City seeks designated channels which can be employed for the purpose offacilitating the coordination of construction of new systems being deployed, e.g. the UHF system that is being constructed County-wide to provide local interoperability throughout Northern Illinois; existing systems, e.g. the City's 800 MHz radio facilities that require RF connectivity to the Statewide Astro 21 network; and to facilities interoperability in the extended use of VHF radio systems employed by firefighters throughout the region. The requested UHF channels would also provide necessary RF linkage for the City's emergency medical personnel. Over 925 paramedics and command personnel provide EMS services to City residents on a UHF system that is extremely limited in system capacity. There is no way to upgrade the system and concurrently move it toward interoperability by redeployment of the existing channels. Any downtime of the system caused by shifting facilities, rather than adding UHF links, at this time would be disastrous. The requested temporary authority to operate on the proposed UHF links would also serve this vital purpose to provide an RF bridge between what is now in place and what will be deployed in the future via a system redesign and upgrade. Similarly, the City operates its present VHF systems to support the over 2,500 fire fighters that protect the City against disasters. The present system was never designed with interoperability as a goal and the City is attempting to take immediate steps toward rectifying this situation, again, to allow all City departments the advantage of greater interagency cooperation and coordination. To provide the necessary spectrum to transition this system toward full interoperability and to increase the overall utility of the existing VHF radio system, the City proposes to employ the VHF channels identified herein on a temporary basis to bridge the gap in improved system design and capacity, without having to reconfigure existing facilities and lose vital throughput. Finally, the City's use of 800 MHz radio channels are to operate a Citywide emergency siren system and a number of data channels in support of drug enforcement, disaster response, and the Organized Crime division. The systems are in flux for a number of reasons, including the City's participation in 800 MHz re-banding pursuant to FCC Docket WT 02-55. Although the re-banding efforts are arduous and tax severely the resources of the City's radio technical personnel, the City cannot back away from its ongoing efforts to increase the functionality and use of those systems by initiating RF linking to the Astro 21 Statewide project. To delay further the City's efforts to accommodate re-banding to the exclusion of the City's efforts to obtain Statewide interoperability on the State's 800 MHz network at the same time, would be to ignore an opportunity to concurrently re-band, while upgrading network capacity. Obviously, a two-step approach is both inefficient and more costly and does not provide to the City the next vital step toward improved and necessary interoperability.

Metropolitan Pier and Exposition Authority - UHF-T (Chicago)

  • TRS Link
  • The Metropolitan Pier and Exposition Authority (MPEA) is a municipal corporation created by the Illinois General Assembly. Its Board of Directors is appointed by the Governor of Illinois and the Mayor of Chicago. The MPEA facilities consist of the McCormick Place Complex (McCormick Place South, McCormick Place North,McCormick Place Lakeside Center, and McCormick Place West), and Navy Pier. MPEA owns and manages the McCormick Place complex and seeks to promote and operate conventions, fairs and expositions in the Chicago area, in an effort to strengthen the local economy. Featuring 2.2 million square feet of exhibition space, McCormick Place is the largest and most successful convention center in the nation. Historic Navy Pier is also owned and managed by MPEA. MPEA is charged with carrying out the recreational, commercial, and cultural redevelopment and operation of Navy Pier, which has become Chicago's most popular visitor attraction. Navy Pier got its start as a shipping and recreational facility and has evolved into a mustsee family destination offering shopping, restaurants and entertainment attractions. By providing state-of-the-art meeting space perfectly suited for small-to-medium trade shows, Navy Pier's amenities also complement the services provided by the McCormick Place complex. All of these elements combine to make Navy Pier Illinois' number one tourist attraction. For the remainder of this document Navy Pier and McCormick Place will be referred to as the MPEA Campus.

The communication system planned by MPEA will provide internal emergency and non-emergency wireless communications for the entire MPEA Campus. The trunked radio network being implemented that is licensed to operate under call sign WQHC531, will utilize the licensed UHF channels for Campus-wide communications. The trunking technology being deployed will relieve the congestion and drastically improve communications. The new system will also have the capability of providing interoperability with the State of Illinois 800 MHz STARCOM statewide network and the City of Chicago’s Emergency Communication network to allow on-scene coordination in the event of an emergency.

From Application I. Extended Implementation Justification

Metropolitan Pier and Exposition Authority (MPEA) respectfully requests an extended implementation of a complex and comprehensive public safety communications system under the FCC Rules and Regulations C.F.R. 47, Part 90, Section 629 for the system currently being implemented under call sign WQHC531. During the course of designing this system Metropolitan Pier and Exposition Authority determined that, due to heightened level of vigilance and the availability of technology that will improve interoperability with surrounding city, county, state, and federal agencies, additional functionality should be specified; thus, increasing the cost and the time for construction. The system that was originally envisioned by MPEA was a fairly mundane UHF network for internal public safety communications. Internal design reviews of this network raised questions and concerns associated with the inability to communicate with state and local first responder agencies. MPEA and the network equipment supplier researched the various options available and significantly modified the network design. The current design of the system provides interoperability with the State of Illinois 800 MHz STARCOM statewide network, plus the City of Chicago’s UHF emergency dispatch network. The equipment and technical hurdles of linking a UHF network with an 800 MHz network coupled with the intra-governmental agreements that must be negotiated added significant scope and cost to the project; thus increasing the length of time to complete the project. Provided herein is MPEA’s evidence that the project is scheduled and requested on MPEA capital improvement plan and in the best interest of public safety.
