In this letter, we present the solution which describe coupled stationary, one dimensional propagation of a nonlinear electron wave and a nonlinear ion wave including the effect of trapped electrons. It is shown that in the scales much larger than the debye length, trapped electrons cause soliton to be supersonic and therefore the condition for the Langmuir soliton to radiate a resonant wave with phase velocity equal to soliton velocity is not fulfilled [1].
