With PaW Mode C you get altitude but no bearing or range
The Zain’s was indeed a mighty product and shame it folded – though doesn’t that speak volumes.
As cellular connectivity improves there will be a point where the viability of rebroadcast traffic does become a no brainier. But then the analogy is with ground based navigation beacons – you need enough coverage for it it to work.
@Peter the value prop is that at the moment – unless you have top end avionics, you need a box to receive traffic and potentially multiple ones if you want the best coverage (types). You then need a separate box if you want weather (away from cellular). You then need to monitor if you have cellular to decide where to get your data from. And loads of cables and boxes and apps. And to top it off – you can’t show them all concurrently on some EFBs – like SD.
