With the rapid development of wireless communication technologies, short-range wireless communication is increasingly being used in fields like smart homes, industrial control, and smart agriculture. This paper focuses on the RFchip ADF7021, proposing a low-power, cost-effective short-range wireless communication solution that offers feasible hardware design and system integration ideas for relevant applications. Short-Range Wireless Communication Technologies Among various short-range wireless communication technologies, this paper selects a low-power wireless communication solution based on digital RF transceiver chips. This solution uses a general-purpose microcontroller paired with a specialized RFchip as the core, offering both flexibility and ease of development. When selecting the RFchip for this solution, the ADF7021 stood out due to its high receiver sensitivity (-121 […]<\/p>\n","protected":false},"author":1,"featured_media":1356,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[30,31],"tags":[36],"class_list":["post-1378","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-insights","category-blog","tag-yvette-wu"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts\/1378","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/comments?post=1378"}],"version-history":[{"count":1,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts\/1378\/revisions"}],"predecessor-version":[{"id":1379,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts\/1378\/revisions\/1379"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/media\/1356"}],"wp:attachment":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/media?parent=1378"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/categories?post=1378"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/tags?post=1378"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
