Ummmm, I don't know if all three are working on a "mesh" system. Only Mr. Beans announced the concept. Only thing I gather is there will be a "size" improvement
of said devices. One must remember the propagation is not that great on 900Mhz and even with a 1/sec update rate on the tracker, one cannot expect to decode every
position. In reality, enough positions get through to affect a recovery though. Even with the 1 watt 900Mhz Multitronix tracker lost packets can be observed with
very high altitude flights. The decode rate is a lot better no doubt than lower powered systems.
The only way to improve the decode rate is increase the sensitivity of the receiving station with a better antenna (or electronics), use a "better" higher gain antenna on the tracker or increase
the power output on the tracker. There might be some advantages to using a different mode of transmission and decoding but the first three are easier to achieve.
A better antenna on the receiving end is true and easiest to do on any system. A better antenna on the tracker may not be possible due to size constraints. More power output on
the tracker can only be achieved with higher power requirements and perhaps an increase in physical size of the components. A different mode of transmission and receiving the
example may be had by weak signals communications like JT65 and a host of others:

In that case the way the data is transmitted and decoded is altered and optimized to the purpose. Am afraid with decoding a high rate of data one might
be limited to what is practical.
Anyhow, I can't wait to see what is going to be offered in the future. Kurt
