Aujourd'hui, nous allons pr\u00e9senter une m\u00e9thode pratique.<\/p>\n\n\n\n<p>Un moyen fiable de tester la distance de brouillage effective consiste \u00e0 utiliser plusieurs t\u00e9l\u00e9phones mobiles de diff\u00e9rentes bandes de fr\u00e9quences pour effectuer des essais sur le terrain. Cette m\u00e9thode permet d'\u00e9valuer de mani\u00e8re exhaustive l'effet de brouillage du brouilleur de signaux, et elle est pratique, sans souci et r\u00e9alisable. Contrairement aux logiciels de test de t\u00e9l\u00e9phones portables ou aux instruments professionnels, cette m\u00e9thode est facile \u00e0 ma\u00eetriser. Les \u00e9tapes sont les suivantes :<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Pr\u00e9parer les t\u00e9l\u00e9phones mobiles de diff\u00e9rentes bandes de fr\u00e9quences, y compris Mobile, Unicom, PHS et 3G (il existe trois normes : Mobile TD-SCDMA, Unicom CDMA2000 et Telecom WCDMA).<\/li>\n\n\n\n<li>Mettez en marche le brouilleur de signaux de t\u00e9l\u00e9phones portables et tenez chaque t\u00e9l\u00e9phone portable s\u00e9par\u00e9ment.<\/li>\n\n\n\n<li>Testez progressivement le rayon de brouillage effectif du brouilleur de signaux, de pr\u00e8s \u00e0 loin. Il est recommand\u00e9 d'utiliser le brouilleur de signaux <a href=\"https:\/\/www.jammersignal.com\/fr\/\">brouilleur<\/a> comme point de d\u00e9part du test et tester la distance de brouillage dans plusieurs directions en m\u00eame temps.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><a href=\"https:\/\/www.jammersignal.com\/fr\/produit\/handheld-4g-5g-jammer-vhf-lojack-wifi-gps-16antenna\/\"><img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/high-performance-jammersignal-4g-5g-jammers-1.jpg\" alt=\"brouilleurs jammersignal 4g 5g haute performance (1)\" class=\"wp-image-1529\" style=\"width:500px\" srcset=\"https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/high-performance-jammersignal-4g-5g-jammers-1.jpg 800w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/high-performance-jammersignal-4g-5g-jammers-1-300x300.jpg 300w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/high-performance-jammersignal-4g-5g-jammers-1-150x150.jpg 150w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/high-performance-jammersignal-4g-5g-jammers-1-768x768.jpg 768w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/high-performance-jammersignal-4g-5g-jammers-1-600x600.jpg 600w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/high-performance-jammersignal-4g-5g-jammers-1-100x100.jpg 100w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/a><\/figure>\n\n\n\n<p>Pour v\u00e9rifier si le signal du t\u00e9l\u00e9phone portable est bloqu\u00e9, vous ne pouvez pas vous fier uniquement \u00e0 l'intensit\u00e9 du signal affich\u00e9e sur le t\u00e9l\u00e9phone portable, car l'intensit\u00e9 du signal est parfois inexacte et ne peut pas refl\u00e9ter l'\u00e9tat actuel de la communication. Au lieu de cela, vous pouvez utiliser votre t\u00e9l\u00e9phone portable pour appeler par intermittence des num\u00e9ros gratuits locaux ou des lignes fixes. Si l'appel \u00e9choue, cela signifie que le t\u00e9l\u00e9phone se trouve toujours dans la zone de brouillage. Si l'appel est connect\u00e9, cela signifie que le t\u00e9l\u00e9phone se trouve en dehors de la zone de brouillage.<\/p>\n\n\n\n<p>Apr\u00e8s avoir test\u00e9 toutes les bandes de fr\u00e9quences, s\u00e9lectionnez la bande de fr\u00e9quences ayant le rayon de brouillage le plus court comme rayon de brouillage effectif du brouilleur de signal de t\u00e9l\u00e9phone portable dans une zone donn\u00e9e. Cette estimation peut guider le d\u00e9ploiement des brouilleurs dans une zone plus large.<\/p>\n\n\n\n<p>La m\u00e9thode ci-dessus constitue un moyen efficace et direct de tester le rayon du brouilleur dans un environnement sp\u00e9cifique. Toutefois, il est important de ne pas se prononcer trop t\u00f4t. L'efficacit\u00e9 du brouilleur sera affect\u00e9e par les stations de base situ\u00e9es \u00e0 proximit\u00e9. Si le brouilleur r\u00e9pond aux exigences du site d'essai, il peut \u00eatre utilis\u00e9 en toute confiance.

Cette r\u00e9sistance am\u00e8ne le t\u00e9l\u00e9phone \u00e0 ajuster sa puissance de transmission pour que l'appel aboutisse.
