In the case building is large like high rise apartment or office building, interference area generally becomes wider. <\/p>\n<p> In other cases, when a number of wireless devices are used on the same channel or adjacent channel, the channel interference causes serious degradation of singnal or noise. <\/p>\n<p> Micronix handheld spectrum analyzer is very inexpensive. And it enables to measure in a wide frequency range from 50KHz to 8.5GHz which includes digital terrestrial broadcasting band\u3014440-770MHz\u3015and wireless devices band\u3014600-820MH\uff5a\u3015. <\/p>\n<p> Morever, as our spectrum analyzer is compact, lightweight and baterry drive, it is suited for field use. <\/p>\n\n\n\n<h2>Solution<\/h2>\n\u2460Radio wave interference of  digital terrestrial broadcasting\n<ul class=\"flexBox flexBoxDivide\">\n<li><img loading=\"lazy\" decoding=\"async\" src=\"\/eng\/image\/application\/denpasyougai-00.jpg\" alt=\"Figure:Radio wave interference of  digital terrestrial broadcasting\" width=\"396\" height=\"211\" style=\"margin-top:2em;width:396px\">\n<p>Researching radio wave interference map is necessary to make a report on the design &amp; construcion plan for the measures against interference.
