   <abstract xml:lang="ru">
    <p>Показан эффект «волновода» при распространении сверхширокополосного сиг-нала внутри помещений, заключающийся в отсутствии интерференционного фактора ослабления сигнала независимо от расстояния. В отличие от открытой местности при распространении в многолучевой среде помещений характер затухания сигнала с расстоянием близок к среде свободного пространства. Эффект возникает вследствие отражения волны от парных поверхностей, расположенных друг против друга: пол — потолок, параллельные стены. Благодаря этому дальность сверхширокополосных систем связи в помещении оказывается заметно выше, чем на открытой местности. Эффект иллюстрируется с помощью трехлучевой интерференционной модели.</p>

   <trans-abstract xml:lang="en">
    <p>“Waveguide” effect that occurs by indoor propagation of ultrawideband signals is shown. The effect exhibits itself in the absence of interference factor of signal dissipation at any distance. Unlike outdoor propagation, the signal attenuation in multipath indoor environment is similar to free space. The effect occurs due to reflections of the incident wave from paired opposite surfaces, e.g., floor – ceiling, parallel walls. As a result, the distance range of indoor ultrawideband communications is essentially higher than outdoors. The effect is simulated in a three-ray reflection model.</p>
