Happy New Year's Eve
Interesting problem that I am incurring here. I was consulted (by the shop making the sale) about a school district wanting to go to a voting system on a single analog pair. From what I've been able to discover, there are ~500 portables in use district wide (UHF), the district is already licensed for 4 different pairs. Majority of the traffic is simplex however, ISD PD uses the existing (EF Johnson?) repeater. The problem is that the PO's can not access the repeater from in the building but as expected, it is full quieting into the building. Outside, the system is usable from the subscriber POV. Somone, unsure of whether it was the shop or district, said voter and that's all anyone wants to do now. However, the other criteria is that a solution must backhaul over an IP network. This is a sale that Icom walked away from...
Anyway, my colleague suggested a Raven IP voting solution with an Icom receivers. I suggested, if the system must be voting, to use the Raven solution with Hamtronics receivers instead.
Then we were given to other little bits of information. The subscribers were most likely near end of life and the administrative staff would also like to be able to use the system. From that information I suggested a DMR Tier 2 system with Roaming using low power "campus" repeaters all linked together. One time slot for PD...another for everyone else (if they want it). Was also thinking about scaling the system for mixed mode operation allowing DMR to be phased in as needed and once analog was phased out...move Tier 3 (possible).
Anyway, what would the readers here on the forum do if in a similar situation (I'm assuming budget is limited).
