KxL system is a complex OTM broadband hybrid modem infrastructure offering enhanced broadband connectivity to the internet through satellites coupled with L band, K band, UMTS band… As carry-on equipment, Airmont smart multi-network management system allows an easy deployment on board while maintaining high level redundant and secured service.


High availability 

Service continuity optimization

When several paths are accessible (satellite, GSM, Wi-Fi), the system connects to the best network, according to user’s predefined requirements (available bandwidth, cost, signal/connection strength and quality...). In addition, in the case of an access path’s failure, the connection is maintained thanks to Airmont smart router, the user is redirected to the best available access path. Automatic and transparent failover from one network to the other makes it completely transparent for the user. There is no need to reset at any time. Ongoing downloadings are not impaired impairduring the swap.

User management

The performance is continuous throughout the cabin: the avionic Wi-fi certified compliance of the smart router allows service continuity for the user wherever heprivilégi is. The system can provide service continuity for the Principle while he is travelling thanks to Airmont user rank system which allows high availability of the service in high congestion’ situation. The Principle benefits from privileged access within the plane. Among aircraft, the client can enjoy preferential access with Airmont’s real time access optimization matrix based on congestion level and end-user consumption.


Within the plane

In case of defective components or the unavailability of a network, the connection path swaps automatically to the most appropriate network channel. The smart architecture enables the network services to be continuous: the service is uninterrupted maintaining an internet access for the user which reduces the downtime.

Ground infrastructure

All the key components of the architecture are doubled (1+1) which allows an internet access with the enhanced performance even while losing an equipment of the system. The system is design without any SPOF (Single Point of Failure). In addition, the infrastructure is housed in a highly secure datacentre (Tier 3/4) based in Paris. Even when the ground infrastructure totally failed, the system does not affect regular internet access.

SLA (Service Level Agreement)

Configuration management, system’s performance and incident management on the equipment enable quick intervention and recovery when failure occurs on the system. To guaranty service excellence, Airmont has established a stand-by service available 24/7. Airmont stand-by service enables immediate on-site response engineer team for any incident detected. Outage management is ensured by the company’s technical support and the company policy on breakdowns management.

Easy to deploy, Easy to integrate

Keeping initial infrastructures with a high system flexibility.

High flexibility

The system is based on carry-on equipment allowing an easy and fast deployment and integration within the plane. In addition, Airmont smart router is avionic compliant and compatible with satcom equipment (STC). Besides, the system is compact and its small size enables an implementation in limited space.

Based on standard live TV antenna

There is no need to set up any antenna in the plane: current antennas (L band and Live TV) are sufficient to enjoy the full capacities and performance of the system (the system does not request Ka antenna).

Airmont evaluation

Experiences and know-how of engineering team acquired in various leading companies allow Airmont to design and to implement end-to-end system in any vehicles. Also, all systems to be delivered are tested beforehand on site by our engineers and can be supervised by the customer itself.

It's so easy to use, with plug and play installation, that Airmont can on request quickly install a trial version.


Strong technology 

Infrastructure within the plane

The carry-on equipment allows fast implementation and an easy access to turn the system on and off. Its small size makes it practical, easy to carry around and discreet, and enables space optimization within the plane and does not request heavy procedures to operate and maintain (update upgrade follow-up, on-site support…).

Strong technology 

Ground infrastructure
Airmont ground infrastructure is hosted in a highly secured datacentre, with more than 25 years’ experience in the industry, which include physical security and using industry accreditations and approved standards among with:

- ISO 9001:2008 (Quality Management)
- ISO 27001:2013 (Information Security)
- ISO 14001:2004 (Environmental Management)
- ISO 22301:2012 (Business Continuity)
- ISO 50001:2011 (Energy Management)
- BS OHSAS 18001:2007 (Occupational Health & Safety)
- PCI-DSS (Payment Card Industry Data Security Standard)
- RMADS (Public Sector Compliance)
- G-Cloud. Leading

All equipment within the infrastructure are redundant. The security is enhanced thanks to firewalls, DMZ and the use of the router strictly limited to open source. In addition, to guarantee security and quality, Airmont’s system fulfils the requirements of the ANSSI, the French Network and Information Security Agency. Airmonts' remote monitoring and supervisory system  enables a permanent check-up of the equipment. The system gives the engineers the capabilities to carry out real-time updates for corrective and preventive maintenance.

High performance 

Response time

Reduced by 15% minimum, with jitter divided by 2.

Rate compare to current installed internet

CIR >= 1 Mbps.

Webpage LoadTime divided by 4.

Commited rate (CIR)

Committed Information Rate for each Airmont user : from 0 to 3.5 Mbps with the ability to assign priorities between the aircrafts, thanks to Airmont real time access optimization, and between the users of a same aircraft, with user rank system.

Time to activate

Time to activate the system (system log-on) after implementation in less than 1 minute.

Quality of connection

Constant performance and quality of the connection throughout the cabin is performed through reference already deployed equipment for many years. The Wi-Fi distributed onboard is STC approved. The system has been designed to offer a switch from one network to another as seamless as possible.

Smart architecture 

Smart system

By keeping a permanent monitoring of the service (including connection status of the equipment and the networks), the system enables to identify the most appropriate network to connect with, allowing service continuity and a seamless access for the user with full transparency. The system can also detect in real-time any failure and deficiencies of the system within the plane and on the ground station. Airmont engineers can provide an immediate and appropriate response to resolve the incident.

User rank system, priority assignment

KxL system allows to define different priorities regarding the access and the use of the service according the user rank: the resources are allocated in accordance with the assigned priorities and the related rights. The system’s algorithm can be adjusted according to services provided and the users connected to the system.

ROI optimization 

Master your ROI with a flexible business model

There is no need to set up another antenna in the plane (e.g no need of Ka antenna which is significantly costly). The platform can be directly implemented with the existing system onboard: there is then no installation cost. In addition, there is no need of a specific antenna and thus to grant supplemental type certification (STC) which would request the aircraft manufacturer approval. By choosing the most affordable bandwidth, KxL system guarantee a cost-effective internet use.
