Data Communications Network Services The data communications network services (DCNS) forms an essential portion of the FAA’s NextGen initiative, which will help to reduce congestion of the airways over the busiest global cities, improve flight safety and increase the efficiency of real-time communications with the replacement of voice with digital data transmissions.

The data communications network services contract is a portion of the 7 year, $150 million that was awarded to the Harris Corporation last month.  The entire contract for data communications integrated services, of which DCNS is a part, was awarded last September to Harris.

ARINC is providing data communications network services under DCNS that will assist the FAA with the integration of its end-to-end data communications system.  ARINC’s services will include the enabling of Communications Service Provider (CSP) network access and the provision of professional services for test, engineering integration and implementation of DCNS into the Data Communications System.

ARINC and the FAA go back a long way, with a working relationship that has been in place for over 50 years.  The industry-leading communications providers pioneered the now standard ACARS messaging system and have been involved in data link technology since as early as 1978.

John Belcher, Chairman  & CEO of ARINC Inc said, “Our DCNS work will tackle some of the most crucial issues in the aviation industry—saving fuel, reducing flight times and increasing air traffic capacity. We are proud to be building on our industry-leading legacy by providing solutions that have met the aviation needs of the past and will help solve the challenges of the future.”

Seal Dynamics, one of the world’s largest and diverse suppliers of aviation parts and components becomes one of the latest customers for ARINC’s industry-leading AviNet Mail.

Based in the U.S. and with field locations across the globe, Seal Dynamics are committed to meeting customer demand, fulfilling hundreds of daily orders of FAA PMA approved, self-manufactured parts and components from OEM-approved manufacturers for the International market.

With a focus upon reliability and timely delivery of critical parts for airlines, Seal Dynamics needed a solution that provided essential back-up for their electronic ordering system.  Their reputation depends upon excellent service and efficient processing of parts orders to ensure the continuity of airline operations.

ARINC Incorporated, with their global reputation for the provision of innovative communications solutions proved that AviNet Mail is more than capable of the job in hand. Using Type B messaging services to handle critical communications is a daily occurrence for ARINC, serving many hundreds of aviation customers with decades of industry assurance of delivery and utmost reliability.

‘We chose ARINC’s AviNet Mail because it provides us with high message reliability, ease of use, accessible support, alternative methods for accessing Spec2000 messages and on-demand traffic analysis’ said Seal Dynamics Vice President of Technology, Marc Alter.

Yun Chong, ARINC Vice President of Global Network and IT Solutions said ‘ARINC values the opportunity to serve a recognized market leader and we look forward to a long and mutually beneficial relationship.’

It has been announced that LTE-based data communications, despite the on-going development of LTE consumer networks, will not be accessible for mission critical communications until 2018, according to Critical Communications Broadband Group (CCBG).

It is not until 2020 that mission critical users can expect reasonable quality voice services using Long-Term Evolution technology.

Data-only LTE services are commercially operational, but consumer based voice LTE solutions are a long way off yet.

According to Phil Kidner, Chief Executive Officer of the TETRA & Critical Communications Association (TCCA) ‘Achieving industry synergy is crucial to ensure uninterrupted availability of mission-critical communications services. LTE is currently designed for commercial use.  There is no viable replacement on the horizon for the current technologies employed by critical communications users.

To provide a necessary footing for mission-critical communications, four key areas within LTE standards must be addressed, to ensure the moving-forward of the technology towards multimedia communications:

  • Group Communication System Enablers
  • Proximity-based Services
  • Public Safety Network Resiliency
  • Push-To-Talk (PTT)

The acceptance of GSCE and ProSe by 3GPP as WID’s that will be integrated into the planned Release 12 of 3GPP LTE specification in 2014 is notably a major breakthrough by the CCBG.

A weakness lies in the framework of Critical Networks Resilience in LTE design, being no provision for the accommodation of any potential loss of signal between the base station and the core communications network.  The hope is to include a solution in the planned Release 13 of 3GPP LTE in 2016.

Other mission critical data communications suppliers such as ARINC do offer a platform for communication needs suited to the military and government with simultaneous voice and data communications with optional guaranteed bandwidth for those high traffic critical services.
