Hi Rb's are sensitive to humidity, pressure, temperature, and magnetic field. You can probably control the temperature. With some effort you can control the humidity. Magnetic field and pressure are a bit harder.

Somebody might have numbers for that, or be able to collect them. A TBolt that gets moved to a new location will have to do a new survey. How long does that take? How stable is the frequency during that time. How much better is it if the TBolt stays powered during the ride? How does that compare to a Rb? What's the recovery from power off look like for a Rb? How sensitive to vibration from transportation are they? -- These are my opinions, not necessarily my employer's.
