 Customer not a happy camper !

 During a flight test with a customer, it became clear something was missing to get full user experience when streaming on internet or making a video conference.

This user had to change WIFi (hotspot) for each services: ATG on a first WiFi, KA band on another WIFI, and cabin light setting on another …

This is NOT user friendly. On his face it showed, this guy is not happy !

I then became involved in Full Cabin Network integration to install a single WiFi hot spot but having access to ALL onboard internet sources and features.
A smart Router will do the trick, but would connect to ONLY 1 source at a time.
Most Routers today will switch from a WAN to another but with a time delay and a connection lost.
More advance algorithm can be used to take advantage of multiple source simultaneously and getting the max Data rate and share to multiple users.

Below is the Concept behind this Patent !

 Plain English description:

 Concept and method for an onboard computer algorithm (router) to transmit a stream of DATA associated with a user device .

 This method is applicable to many types of vehicles ie: Aircraft, train, ship, boat and similar. The concept is referring to a Router establishing a link
to a device and then another link to internet via on board transceivers/modems connecting to satellites.

In summary a user in an Aircraft has access to internet .

The defined Router contains software performing pre-designed features, for example:
- Use of multiple WAN’s simultaneously to transmit/receive DATA (Multipath)
- Seamless transfer from a WAN to another (WAN1 to WAN2)
- WAN combination or link to augment bandwidth and share Data to multiple users.

The Router contains an advance algorithm and a set of decision metrics to perform automatically the above WAN priority and transfer to becomes
totally transparent to the user. From a basic fail-over table to multiple metrics ie: Flight region, DATA speed, signal quality, to name a few.
Each WAN is weigthed dynamically to be set in the correct priority sequence.
Using multiple valid WAN’s the system can switch from WAN1 to WAN2 if WAN1 is lost.
In this scenario WAN2 is a backup and operation is a seamless transfer and is transparent to the user.

It is assumed multiple systems are installed in the vehicle (Aircraft). Ie: a combination of Satellites systems and/or Air-to-Ground systems and on
Ground cellular system. The end result, the user is allways connected in all phases of flight and has backups to maintain connectivity.
Link bonding , link aggregation and/or Load sharing/balancing are some technics used in the Multipath feature to combine WAN’s and augment bandwidth
and provide better Data rate and overall performance to users.

The above is built in Layer-1 (Physical Architecture ) and Network Layer-2/3.
The user device is defined as : a smart phone, tablet, or Laptop connected via a single wireless LAN or to wired LAN to a smart Router.
The smart Router is the Network central intelligence making the connections from transceivers on the WAN side to devices on the LAN side.
The device does not needs to change wireless LAN (WiFi SSID) to run all those features above.
