Single Type J DLNA Module Reduces 5G Interference

A TSO-approved module designed to reinforce L-band satcom signals is now available via Honeywell, aimed squarely at aircraft operators concerned about the impact of 5G cell network interference.

The Type J DLNA device can "limit the effects of cellular interference on certain satellite communications (satcom) systems for aircraft communications". Honeywell’s Type J DLNA (Diplexer/Low Noise Amplifier) was designed as an upgrade for those using the firm's Inmarsat L-band network, used around the world by carriers and aircraft operators for long-range communications. The module will prevent interference from 'Ancillary Terrestrial Component networks', or tech-speak for the umbrella of cell networks in use groundside. Global LTE and 5G networks, particularly those operating in frequency bands adjacent to the Inmarsat L-band network, have proven to be a source for infrequent but irritating headaches for operators, causing comms disruptions and expensive flight delays. The Type J DLNA is a single line-replaceable unit upgrade to existing Inmarsat L-band systems, available to all operators using class 6 or 7 satcom systems.

“There has been growing concern globally that certain 5G services could interfere with some aircraft satcom systems, and the Type J DLNA can limit those effects,” said Steve Hadden, vice president and general manager, services and connectivity, Honeywell Aerospace. “With the upgrade, airlines and aircraft operators will continue to have access to Future Air Navigation System routes, which allow airplanes to fly at their optimum altitudes and burn less fuel. That creates a significant reduction in flight durations and fuel costs while improving overall flight safety.”
