Description	Work presents simulations of positive and negative streamers propagating between two point electrodes in preheated air at atmospheric pressure. Seed charges are taken into account in the interelectrode gap. The influence of the pulsed voltage frequency on the discharge structure has been studied. For the studied discharge regime, a change in the applied voltage frequency corresponds to a change in the pre-ionization background. Range of pre-ionization values from 10^4 and up to 10^9 cm-3 . The pre-ionization background has a small influence on the electron density, electric field and location of the negative streamer head. Conversely, it has a significant influence on the positive streamer characteristics. Short time averaging of a few nanoseconds, which corresponds to currently used instruments, the structure of the time-averaged emission of the 2PN2 is different from the instantaneous one and shows negative and positive streamers with smaller radial expansions and more diffuse streamer heads.
