CAT-M vs LTE-M (Long-Term Evolution for Machines) are two different names for the same thing: a device category in the LTE family of cellular technologies designed for IoT applications. CAT-M and LTE-M devices have some advantages over traditional LTE devices, such as lower power consumption, longer battery life, better coverage, and lower cost. However, they also have limitations, such as lower data rates, narrower bandwidth, and reduced functionality. The main differences are: CAT-M vs LTE-M Bandwidth CAT-M and LTE-M devices use a bandwidth of 1.4 MHz, which is much smaller than the typical 20 MHz bandwidth used by other LTE devices. This means that they can fit more devices in… \u7d9a\u304d\u3092\u8aad\u3080 \u00bbCAT-M vs LTE-M\uff1a2\u3064\u306eIoT\u6280\u8853\u306e\u672c\u8cea\u7684\u306a\u6bd4\u8f03<\/span><\/a><\/p>","protected":false},"author":1,"featured_media":16090,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"categories":[268],"tags":[16],"class_list":["post-15999","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-iot-faqs","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts\/15999","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/comments?post=15999"}],"version-history":[{"count":0,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts\/15999\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/media\/16090"}],"wp:attachment":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/media?parent=15999"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/categories?post=15999"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/tags?post=15999"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
