By providing first responders with several interoperability options, Motorola helps ensure seamless communications across public safety agencies and jurisdictions so they can effectively coordinate a joint response.

The newest offering is the unique, customer focused, Motorola Managed ISSI Service. Motorola eases system implementation by operating the interoperability network and coordinating with each agency system on the network. All talkgroup mapping and provisioning between agencies is also managed by Motorola so agencies can focus on their objectives.

P25 ISSI technology enabled four public-safety radio networks to come together as one

To ensure its Managed ISSI service could connect P25 trunked systems over a large geographical area, Motorola conducted a trial in Texas, last fall. Four IP-based P25 trunked systems operating on multiple frequency bands in Austin, Laredo, Harris County and Parker County were connected to Motorola's NOC in Illinois by ISSI prototype gateways to provide interoperable talkgroups that would allow Texas first responders and their commanders to be in direct radio contact, even if they were hundreds of miles apart. As a result, 70 users from 25 different agencies were able to roam freely and communicate seamlessly with each other while remaining in radio contact with their home dispatchers.
