WAIS – Wide Area Interoperability Solution

A Wide Area Interoperability System (WAIS) interconnects communications systems over existing network infrastructure – allowing users of disparate radios, PTToC, telephones, satellite phones, and dispatch centers to communicate with each other locally, regionally, or in systems that span entire states.

Additional Information:

The Wide Area Interoperability System scalable solution links multiple communication devices via any IP network: LAN, WAN, or the Internet. Deployment of many systems in the US and around the world, range from a few sites to entire statewide systems and larger, incorporating both fixed sites and mobile platforms. Operators stationed at control points anywhere on the network easily form and disband multiple-user talk groups.

Solution Summary:

  • All ACU gateways are WAIS-compatible: ACU-T, ACU-M, ACU-1000, ACU-2000IP, and ACU-5000. NXU-2A compatible for single end-device sites.
  • LAN, WAN, or the Internet can be used to link sites.
  • Dispatch capabilities allows monitoring of end users or direct two way communication links, as desired.
  • Multiple vocoder choices allow bandwidth optimization.
  • Distributed design approach eliminates single points of failure and ensures reliable communications.
  • Local Interoperability Systems remain operational in the event of network failure or loss of other system infrastructure during a disaster.
  • New control points or system users can easily be added at any time to any point in the network.
  • Operators can easily customize their software interface using the large and expandable icon library.
  • Access is password-protected. Administrators can also use passwords to limit operator access to specific system assets.

On the left the Local Interoperability Sites (LIS) are in the brown color.  These are individual JPS interoperability hardware components:

  • ACU-2000,
  • ACU-5000,
  • ACU-M,
  • ACU-T,
  • NXU-2A.

On the right in the blue, is the breakdown of the resources available for each available LIS.  The numbers indicate:

  • Talkgroups,
  • Channels,
  • Phones,
  • Other JPS Hardware,
  • Links to:
    • Radios,
    • JPS Hardware
    • Other devices or end points:
      • SIP
      • JPS RoIP

The RED sites are not available at this time, either they are mobile sites that are off, or the link to the sites is down.  The RED channels or TalkGroups are links that are down at this time.

WAIS Architecture:

JPS’s industry-standard ACU family interface communications devices such as radios, telephones, VoIP phones, satellite phones, etc. .

Any number of local ACU-base systems, along with operator stations and other communications assets, link to create a WAIS.

Single, independent users or radio systems not part of a local ACU can join the WAIS using JPS’s NXU-2A radio interface unit. The WAIS distributed architecture has no single failure point, so local systems continue to operate independently during network outages or following failure of infrastructure during a disaster.

The design of the system is to maintain operation even if infrastructure is lost due to natural disaster or other type of incident.

The system’s distribution architecture ensures that, if any system hardware or segments of the inter-systems communications links break down, all other portions remain operational. Local interoperability remains viable even if all outside communications links are down.


WAIS Controller:

Operators use the WAIS Controller to manage system resources via its intuitive Graphical User Interface. Its Overview screen manages connections among all or any subset of sites, and an operator can switch to the Local View when it’s advantageous to focus on a single site. Every site and communications end point has its own graphical icon, making each easy to identify at a glance. The WAIS Controller monitors the system and its network connections, keeping operators apprised of real-time system status. Password-protected permission sets covering individual sites or specific endpoints allow operators to monitor and control the entire system or restrict them to limited portions of it.

Dispatch Features:

The WAIS Controller’s Wide Area Interoperability System dispatch features, available with the Enhanced and Enterprise versions, allow operators to monitor or communicate directly with end users.

Users maximize flexibility by making use of the sound card of the operator’s PC. The WAIS Controller Dispatch View gives an intuitive and customizable view of all dispatch assets. Operators monitor multiple end points and chose to communicate with individual end points or the entire interoperability net that the an end point is a member of. The Enterprise version fans out endpoint audio to multiple dispatchers, allowing simultaneous monitoring.

The Dispatch Screen can:

  • Monitor Sites
  • Select Individual Sites to dispatch to
  • Select a group of sites to dispatch to
