Aero+ Velocity IP aggregation and four channels of Inmarsat’s Swift Broadband X-Stream service, gave a 1.4 Mbps connection.
Eclipse says that its Paris-based engineers have tested its Aero+ Velocity IP aggregation solution with four channels of Inmarsat’s Swift Broadband’s X-Stream service, resulting in a stable 1.4 Mbps connection.
The Aero+ Velocity software was running on a Kontron ACE Flight 600 and the Cobham JetLan AS250 airborne servers (Aero+ Velocity can operate on any airborne Linux-based server).
The four channels of X-Stream were provided by a four-channel Cobham satcom system consisting of the SDU-7330 and HPA-7450.
Eclipse says that its customers have historically seen 350–400 kbps per X-Stream channel, and bonding two of these regularly results in 700–800 kbps.
But what surprised the team was the relatively high availability rate of four channels of X-Stream simultaneously.
Eclipse’s Shaun Flanagan said: “There was initial concern about the network’s ability to provide such resources as our Paris labs share a spot beam with some pretty heavy users, including Inmarsat themselves whose antenna-riddled London headquarters’ rooftop is evidence of the testing that goes on inside.
“Despite this, our engineers were able to establish a connection for four channels of X-Stream for a high percentage of the time.”
Once the stable connection was up and running it was necessary to use some IP configuration skills to optimise the connection, including adjustments in MTU size.
Given the fact that most customers requesting these levels of bandwidth are transmitting video, this is the application Eclipse focused on in its labs.
Eclipse recently integrated Aero+ Velocity into the medical system installed aboard a Middle Eastern customer’s aircraft. With the level of connectivity provided by Aero+ Velocity (IP aggregation) and the flexibility provided by Aero+ Connectivity (satcom and on-board network configuration) the customer is now able to enjoy the convenience of being connected to voice and data communications during normal operations and have the all-important high speed connection available to the ground should the hospital facilities need to be used.
Eclipse’s Aero+ Connectivity satcom and on-board network configuration tool allows the customer to set various easy to activate profiles for various in-flight requirements.
For standard internet access a basic “office-in-the-sky” profile is activated, allowing passengers to access the internet via Wi-Fi while also allowing the on-board communications personnel to designate which devices/users/zones can access the network and what services are available to them.
When a VIP is on-board Aero+ Connectivity allows for a specific, adjustable allocation of bandwidth to be assigned to the VIP passenger.
And in medical emergencies the operator can activate a profile which allocates all available bandwidth to the medical systems.
In this case Eclipse’s Aero+ Velocity (IP aggregation) solution aggregates two channels of Inmarsat’s SwiftBroadband X-Stream service to provide 700–800 kbps of connectivity.
