3. 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

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

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

6. 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

7. 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

8. 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

9. 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?

10. 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)

11. 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

12. 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
