Instant WiFI and LTE switching

Description

When using some service (video, streaming music, maps, etc.), when one signal disappears, switch instantly to the other available connection, preferably without interruption.

Competitive/Pricing/Notes

Network connections to the car change at about the range of my garage. This can cause

• streaming music to stop
• summon to be interrupted when the car switches between WiFi/LTE or my phone changes between WiFi/LTE
