This week the project managers from Lapeer County 9-1-1 and Motorola along with a team of Motorola, Pyramid Network Services LLC and Infinigy Engineering & Surveying engineers went to visit all the sites that have been previously chosen to bring needed coverage to the county. Also in attendance were technicians from the state MPSCS who will also work closely with the Motorola and county teams.
Detailed site drawings were ether taken or acquired from past surveys for all sites. Photographs were taken and discussions on equipment, placement, layout and construction also occurred. Plans are beginning to form on how everything will be put together and how the cutover from the old system to the new system will happen.
According to our plans we will have 9 VHF paging sites and 7 800MHz voice sites. The entire system will be simulcast and linked together via microwave.
- Columbiaville water tank: VHF pagng with PTP microwave
- A site in North Branch: VHF paging with PTP microwave
- MPSCS site 3802: VHF paging and 800MHz voice with microwave
- A site on Deanville Road east of Van Dyke (Lapeer County Road Commission property): VHF paging and 800MHz voice with microwave
- Existing site at Lapeer County Central Dispatch (Prime Site): VHF paging and 800MHz voice with microwave
- Existing site in the Imlay City industrial park: VHF paging and 800MHz voice with microwave
- A site in Hadley Township on Fox Lake Road west of Hadley Road: VHF paging and 800MHz voice with microwave
- Metamora Village water tank: VHF paging and 800MHz voice with microwave
- Almont Village water tank: VHF paging and 800MHz voice with microwave
- There will also be a microwave link to MPSCS 2102 in Addison Township, Oakland County to loop some of the other sites back around to the prime site. This was chosen because microwave path studies predicted some unacceptable path fading in some of the other path scenarios.
Some equipment and shelters will be either converted or moved from one location to another for reuse.
Full site drawings will be worked up following these site walks with equipment considerations included in them. They should be ready for review by the County and MPSCS by April. Speaking only preliminarily, we could begin to turn dirt by late spring to early summer.
Weekly meetings or teleconferences will begin next week between the County and Motorola to ensure the workflow moves along and to keep each other updated on progress and work out any issues that will arise.
