What is the difference between NEXEDGE and DMR?

Due to narrowbanding mandates by the FCC in 2013, we are left with two differing digital protocols. A highlighted difference between NEXEDGE and DMR is the ability to have overlapping conversations on one frequency without interference. NEXEDGE allows for one conversation or talk path per frequency while DMR offers the ability for two conversations or talk paths to take place simultaneously on one frequency without interference. As a tradeoff, NEXEDGE provides a better talk range.

What is the difference between Analog and Digital?

The main difference between Analog and Digital is the way signals are transmitted and received.  Digital allows for a minimum of 15% increase in coverage, noticeably clearer audio at greater distances and include more available features for end users.

What areas does J&K cover and service?

J&K is segmented into two sales departments, Industrial Communications (SCADA) and Two-Way Communications, both of which cover differing territories. Two-Way Communications territory is comprised of Indiana, Western Ohio and Southern Michigan while Industrial Communications covers Indiana, Ohio, Michigan and Kentucky.
