A radio link that works while two vehicles are parked may behave differently once they move apart or a building blocks the direct path. If several vehicles, unmanned platforms, or field teams need to share video and data as they move, the question is how those connections will change along

A wireless video link may be described as OFDM on one specification sheet and COFDM on another. That does not tell you which will deliver a clearer picture, less delay, or a more reliable connection. COFDM means OFDM with channel coding for error correction; an OFDM-labelled product may use error

A wireless video link advertised for a long line-of-sight distance may still struggle on a much shorter route behind buildings or trees. Before comparing distance figures, compare the paths those figures describe. For a clear route, the question is whether the proposed link can sustain the required video load over
