Start of Process APCO 2014 New Orleans State of Nebraska finished similar testing Development of process State of Nebraska’s documentation Motorola subscriber ATP documentation Radio fair with radios that pass a qualification process

Excluded from Testing Non APCO Project 25 features Motorola FailSoft GPS tracking Motorola FailSoft

Results of Testing 5 out of 10 portable radios passed the clinical testing Test process included field testing and drive testing Radios were purchased

Post Qualification Issues Scrambled Audio Multiple Vendors have experienced scrambled audio since passing the qualification testing 1 call out of 200 will not decode properly Difficult time with building codeplug, personality, profile The vendors provide enough help to make the radio work, but leave a lot of features left undiscussed Zones versus systems Time to build files

Post Qualification Issues (Cont.) Radios that pass the qualification testing but then fail after fielding Talk permit tone but no tx audio No talk permit tone Scrambled audio (encryption) Out of Range in known good coverage Full spectrum scanning Roaming

Lessons Learned Need larger test pool of users 500 – 1000 PTT’s per radio type Time, current time per radio is one week. This will need to be extended. Maybe 2 months in field with heavy use by users Cost of testing each radio Cost of troubleshooting issues

Lesson’s Cont. Training for staff once radios have been purchased Repair parts for radios Flat rate repair Extended Warranty Need to have knowledgeable individual from vendor on site for testing. APCO P25 encourages competition among vendors. How many vendors can you support?

Lesson’s Cont. System Key issues Feature option One vendor more tightly controlled than others Need ability to tighten restrictions Feature option User selectable encryption keys (model of radio specific) Emergency calls (how are they handled)

Where are We Now? Initially passed 5 vendors (Portables) Purchased 2 different manufacture radios Both radio vendors are having issues We have suspended any new orders for the system No additional testing until issues are resolved with existing vendors

Where are We Now (Cont.) Working with current fielded vendors to resolve issues Tried different code versions Staff time for troubleshooting The County wants this to be successful for competition but also wants users to be safe
