Approved: Paging Tower In Clifford Village

Yesterday evening the Clifford Village Council unanimously approved the construction of a fire/EMS paging tower on Village property and advised that construction could begin immediately.

Motorola will begin ordering the steel and associated equipment for the site and electronics which shouldn’t take too long to come in.

This paging tower will bring much needed coverage to the northernmost portions of the county. We will have the antenna’s pointing in a directional pattern toward the south to cover Clifford, Burlington Township and parts of Rich and North Branch Township’s.

By increasing the coverage footprint in these area’s, the fire departments, medical first responders and Lapeer County EMS ambulances will better be able to receive their calls for service from dispatch. In turn they will be able to get a better response in terms of personnel and timeliness.

Shelter Move: North Branch to Columbiaville

Last week the shelter and generator that we have been using in North Branch since 1996 was lifted and moved to our new paging location in Columbiaville. We’ve moved away from the North Branch site to avoid paying continuing rental fees to American Tower Corporation. This site will also bring improved coverage to the Columbiaville and Otter Lake areas for EMS and fire paging.

The next steps for the Columbiaville site are to bring electricity to the site, install the equipment and then provide connectivity back to the main system. At this time, it is undetermined how long it will take to get connectivity as we are still working out those details.

Below is an 18 minute video cut of the lifting and setting of the shelter and generator.

FCC Approves VHF Paging License

This week the Federal Communications Commission (FCC) approved our amended license for VHF paging for fire and EMS service paging.FCC-logo

LCCD and Motorola are looking to start up the new system and narrow-band the 500+ pagers in the next several weeks.

LCCD would also like to thank the FCC, Industry Canada and Congresswoman Miller’s office for their efforts and work on the license.

Lapeer County Switches to Digital

logoAfter several years of work, Lapeer County Central Dispatch switched from an analog radio system to a digital radio system at 12:05pm on December 18, 2012.

We have doubled the amount of radio towers we use from three to six. We now have sites in Almont Village, Metamora Village, Imlay City, Lapeer City, Burnside Township and Deerfield Township. We absorbed the State of Michigan’s Deerfield site into our simulcast as part of the project.

The analog system had ten frequencies and two of them were dedicated for data usage while the remaining eight were left for voice channels in the trunking system. The new digital system now has fourteen frequencies allotted for voice. Data is no longer used since we changed to a cellular configuration earlier in the year for police in-car computers.

Also, the analog system had a total of 72 talkgroups and through some changes in setups, the digital system has a total of 74 talkgroups available to the various Lapeer County users plus a plethora of neighboring county and state talkgroups.

Lapeer County users are among the first in the state to be ready and capable of utilizing 700MHz frequencies should they become available in the area. Our radios are already programmed for it which means if that time comes, we shouldn’t have to make a fleet-wide change to accommodate it.

We contracted with Motorola Solutions for 95% county-wide coverage on a 3-watt portable radio. Due to FAA regulations at the Metamora site, we had to reduce the tower height by 80 feet which put our coverage projections to 94.96% coverage. Once we completed actual coverage tests earlier this month, we ended up with an amazing 99.89% coverage throughout the county. That includes attenuating the test radios at -15db to simulate in-building coverage in the city/village areas of the county. The rest of the county had the test radio set to be attenuated at -6db to simulate vegetation on the trees.

On the day of the system cut-over, at about 9:00am we began processes of shutting down half of the analog system, moving feed lines and other things at the MPSCS Deerfield site and then turning on half of the channels in the new system. Then the MPSCS began enabling all of our new talkgroups on our towers and surrounding towers. By about 10:30am we began moving users over to the digital system. Once roll call radio checks and pager tests were complete, we finished the cut-over process by turning off the remaining channels of the analog system and turned on the remaining channels in the new system. By 12:05pm the analog system was completely shutdown and all users were operating on the new system.

We are still operating on our old paging system due to licensing issues with the FCC and Canadian Coordination for our VHF frequency. The FCC has granted us a time waiver for the narrowbanding requirement that we must meet. The old paging system is incapable of being narrowbanded. Once we get a license for the new paging system and turn it on, we will be in compliance as that system is already narrowbanded to 12.5KHz.

DTE Energy Brings Power to Metamora

Detroit Edison energized the Metamora tower site today allowing E.R.S. & Motorola to continue stacking the new tower past 200′ in compliance with FAA regulations. E.R.S. is continuing to assemble the tower and tower lights as well as wire up the shelter with the generator and electronics.
