Sensors in the rockets are usually connected by cables, which increases the weight of the rocket and causes difficulties in layout design.

 

Although wireless technology has been widely used in some electronic devices, rockets have to withstand extreme high and low temperatures, strong forces caused by separation, and a complicated electromagnetic environment.
