VoiceLayer's MODULO App Earns FirstNet Certified™ Designation

First Responders on FirstNet Can Now Access MODULO via the FirstNet App Catalog

SAN FRANCISCO, CA, Dec. 2019 – Following a rigorous review process, VoiceLayer's MODULO is now FirstNet Certified™ and accessible via the FirstNet App Catalog.

FirstNet – America's public safety communications platform – features the first-ever App Catalog geared to first responders. This gives FirstNet subscribers a dedicated location to find meaningful new solutions that have been specifically reviewed for use with FirstNet services.

Achieving a FirstNet Certified™ designation means MODULO is a heavily vetted and trusted solution for public safety, meeting FirstNet app requirements. Before any mobile solution can be added to the FirstNet App Catalog, it must pass stringent tests for security, relevancy, data privacy and availability. As a FirstNet Certified™ app, MODULO has been confirmed to meet those requirements, as well as higher requirements for mobility, scalability and resiliency.

Additionally, FirstNet subscribers will also be able to take advantage of the MODULO solution while benefitting from the enhanced security provided by the FirstNet network core, which is the only physically separate network core dedicated entirely to public safety in America.

"We're very excited that MODULO is now FirstNet Certified™. MODULO provides a unique Push-to-Talk (PTT) value proposition." said Taylor Bollman, CEO at MODULO. "MODULO was designed from the start to provide an optimal experience for first responders and other professionals to fulfill the critical needs of the mission. The vanguard core technologies utilized simultaneously in the app deliver superior performance and enable us to offer the service at an extremely competitive price. It furnishes first responders with a full complement of professional features and extensions."

The MODULO app distinguishes itself in multiple important ways.

It is built on superior vanguard core technologies:

  • Server infrastructure: Built on Erlang, developed by Ericsson™ and used by WhatsApp™ for Telco-grade reliability.
  • Transport protocol: Built with QUIC, created and used by Google™ to provide faster reliable transmission over poor network conditions.

And, professional features include:

  • RoIP gateway – for PTT between LMR and smartphones.
  • Tested integrations with professional-grade PTT mic/headset accessories.
  • Admin portal.
  • User and channel management console.
  • Web dispatch interface with integrated mapping.
  • On-premise server support.

Our company and product enjoy a significant cost/pricing advantage:

  • MODULO is built on our own PTT developer platform,VoiceLayer, which is used by other PTT apps and provides a very marketing-light source of revenue.
  • Built on vanguard technologies, MODULO development is extremely efficient. Like MODULO, WhatsApp™ was built on Erlang with 35 engineers for 450M users.

Built with AT&T, in public-private partnership with theFirst Responder Network Authority, FirstNet is bringing public safety a much-needed technology upgrade to help them connect to the critical information they need – every day and in every emergency.

"Only highly secure, high quality, public safety relevant applications are added to the FirstNet App Catalog. And we're pleased that MODULO is now Certified and available to FirstNet subscribers," said Bob Sloan, chief operating officer, FirstNet Program at AT&T. "MODULO will bring public safety additional capabilities to render real-time field communications and dispatch more reliably and efficiently, with more flexibility."

"Through our work with first responders, we heard their need for innovative applications to assist with their lifesaving mission. FirstNet is helping to address these needs, and we are pleased to welcome MODULO to the FirstNet App Catalog," said Mark Golaszewski, executive director of Technology and Innovation, First Responder Network Authority.
