In office, hospital, factory and public institution, the wireless equipment such as wireless LAN, ZigBee, Bluetooth and cordless phone are widely used.  However, the bad effects accompanying the spread of wireless devices have also come out. For example, such situations as lower communication speed than desired,  communication state changing with time and place, and unstable communication occur many times. Since the radio wave is invisible, it is difficult to perform investigation and find out solution for these causes. Moreover, when newly installing wireless applications, it is very difficult to perform channel arrangement without the existing radio wave interference. <\/p>\n<p>When a handheld signal analyzer MSA500 series, a 2.4GHz band antenna M404 and a logging software MAS510 as a tool to solve these problems are used, the radio wave in the 2.4GHz band can be precisely measured.  Since the temporal variation of the radio wave by the site survey over a long time can be known, it is possible to perform the appropriate channel selection avoiding interference when installing wireless access point and equipment.  Moreover, the signal analyzer (real-time spectrum analyzer) can capture the radio wave carrying out hopping at high speed since the processing speed is as fast as 30us.<\/p>\n\n\n\n<h2>Solution<\/h2>\n<p>A wireless device using ZigBee is installed in the environment where radio waves of wireless LAN and cordless phones travel.<\/p>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/eng\/image\/application\/servey2-00.gif\" width=\"730\" height=\"525\" alt=\"2.4GHz band radio measurement before installation of ZigBee equipment\"> \n\n\n<h2>System configuration<\/h2>\n<table>\n<tbody>\n<tr>\n<td><a href=\"\/english\/products\/spectrum-analyzer\/msa500\/msa538.html\">Handheld signal analyzer [MSA538]<\/a><\/td>\n<\/tr>\n<tr>\n<td><a href=\"\/english\/products\/spectrum-analyzer\/option\/mb400.html\">Lithium-ion battery [MB400]<\/a><\/td>\n<\/tr>\n<tr>\n<td><a href=\"\/english\/products\/test-accessories\/m401.html\">Antenna for wireless LAN [M404]<\/a><\/td>\n<\/tr>\n<tr>\n<td><a href=\"\/english\/products\/spectrum-analyzer\/option\/loggingsoftware.html\">Logging software [MAS510]<\/a><\/td>\n<\/tr>\n<tr>\n<td><a href=\"\/english\/products\/test-accessories\/mi400.html\">USBcables [MI400]<\/a><\/td>\n<\/tr>\n<\/tbody>\n<tfoot>\n<\/tfoot>\n<\/table>\n\n\n\n<h2>Products introduction<\/h2>\n<div class=\"woocommerce columns-3 \"><\/div><div class=\"wp-block-vk-blocks-button vk_button vk_button-color-custom vk_button-align-block\"><a href=\"\/eng\/file-download\/application\/pdf\/simple_EMI.pdf\" style=\"background-color:#5b6069;border:1px solid #5b6069;color:#fff;\" class=\"vk_button_link btn btn-md btn-block white\" role=\"button\" aria-pressed=\"true\" target=\"_blank\"  rel=\"noopener\"><i class=\"fas vk_button_link_before fa-file-pdf\"><\/i><span class=\"vk_button_link_txt\">Download This Application Note (PDF) <\/span><\/a><\/div><p><\/p><div class=\"wp-block-cover is-light vk_block-margin-xl--margin-top\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-white-background-color has-background-dim\"><\/span><img class=\"wp-block-cover__image-background wp-image-8105\" alt=\"\" src=\"https:\/\/micronix-jp.com\/wp-content\/uploads\/2022\/11\/contact_cta_cover.png\" data-object-fit=\"cover\"\/><div class=\"wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow\"><p class=\"has-text-align-center has-huge-font-size\"><strong>Please feel free to contact us.<\/strong><\/p>\n\n<p>If you want to verify 5G, customize a radio wave shield box, or need product repair, please do not hesitate to contact us about any small matter.<\/p>\n\n<div class=\"wp-block-vk-blocks-grid-column vk_gridColumn\"><div class=\"row\"><div class=\"wp-block-vk-blocks-grid-column-item vk_gridColumn_item col-12 col-sm-12 col-md-12 col-lg-12 col-xl-12 col-xxl-12\"><div class=\"wp-block-vk-blocks-button vk_button vk_button-color-custom vk_button-align-block is-style-shine\"><a href=\"https:\/\/micronix-jp.com\/english\/contact\/\" class=\"vk_button_link btn has-background has-luminous-vivid-orange-background-color btn-lg btn-block\" role=\"button\" aria-pressed=\"true\" target=\"_blank\" rel=\"noopener\"><div class=\"vk_button_link_caption\"><i class=\"far fa-envelope vk_button_link_before\" aria-hidden=\"true\"><\/i><span class=\"vk_button_link_txt\"><strong>Contact Form<\/strong><\/span><\/div><\/a><\/div><\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>By precise site survey using a handheld signal analyzer, the radio interference will be quickly solved when installing a wireless access point and a relating equipment!
