Gli anziani possono ancora usare il cellulare?<\/h2>\n\n\n\n<p>Con il graduale ritiro delle reti 2G e 3G, molti utenti dubitano della funzionalit\u00e0 dei telefoni cellulari 2G esistenti. La coesistenza di pi\u00f9 generazioni di reti comporta delle sfide. \u00c8 fondamentale comprendere le caratteristiche delle reti 2G e 3G e le ragioni del ritiro.<\/p>\n\n\n\n<p>La rete 2G \u00e8 stata messa in commercio nel 1991 e forniva chiamate vocali e messaggi di testo di base, ma rispetto alle avanzate reti 4G\/5G oggi ampiamente utilizzate, la rete 2G \u00e8 rimasta notevolmente indietro. Secondo i dati della Global Mobile Suppliers Association, a settembre dello scorso anno, 142 operatori in 56 Paesi e regioni del mondo hanno completato o pianificato la chiusura delle reti 2G\/3G.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><a href=\"https:\/\/www.jammersignal.com\/it\/prodotto\/4g-hot-sale-8antenna-handheld-cell-phone-blocker\/\"><img fetchpriority=\"high\" decoding=\"async\" width=\"433\" height=\"433\" src=\"https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/4g-jammer-jammersignal-handheld-portable-jammers-1.jpg\" alt=\"Disturbatore 4g jammersignal portatile (1)\" class=\"wp-image-1763\" srcset=\"https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/4g-jammer-jammersignal-handheld-portable-jammers-1.jpg 433w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/4g-jammer-jammersignal-handheld-portable-jammers-1-300x300.jpg 300w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/4g-jammer-jammersignal-handheld-portable-jammers-1-150x150.jpg 150w, https:\/\/www.jammersignal.com\/wp-content\/uploads\/2024\/05\/4g-jammer-jammersignal-handheld-portable-jammers-1-100x100.jpg 100w\" sizes=\"(max-width: 433px) 100vw, 433px\" \/><\/a><\/figure>\n\n\n\n<p>La coesistenza di reti 2G, 3G, 4G e 5G comporta problemi quali gli elevati costi operativi e la scarsa efficienza nell'utilizzo delle risorse dello spettro. Con l'avvento della tecnologia 5G, la domanda di velocit\u00e0 di comunicazione e di servizi pi\u00f9 avanzati continua a crescere e le capacit\u00e0 delle reti 2G e 3G non sono pi\u00f9 in grado di soddisfare la domanda. Continuare a supportare queste tecnologie comporter\u00e0 uno spreco di preziose risorse dello spettro.<\/p>\n\n\n\n<p>Nonostante la tendenza al ritiro, l'ampia base di utenti e la lentezza della transizione comportano delle sfide. Solo in Cina, nel 2020 ci saranno ancora 273 milioni di utenti 2G, pari al 17,15% degli utenti totali. Molti di questi utenti sono anziani in aree remote che hanno una domanda limitata di smartphone e utilizzano i loro telefoni principalmente per le chiamate vocali.<\/p>\n\n\n\n<p>Ling Li, professore associato presso la Fudan University, ha spiegato che l'iterazione tecnologica \u00e8 la tendenza generale e gli operatori stanno gradualmente abbandonando le reti 2G e 3G. Ma questo processo richiede tempo perch\u00e9 ci sono ancora molti utenti che si affidano a queste reti, compresi quelli che utilizzano le reti 2G\/3G per i sistemi IoT per la gestione urbana.

VoLTE \u00e8 un servizio di chiamata basato sulla rete 4G. Se il telefono cellulare non dispone di questa funzione, non pu\u00f2 essere utilizzato e gli utenti devono acquistare un nuovo telefono cellulare. Attualmente \u00e8 possibile aggiornare gratuitamente la scheda SIM del cellulare 2G con una scheda SIM 4G o 5G senza modificare il piano esistente.<\/p>\n\n\n\n<p>In sintesi, con la graduale eliminazione delle reti 2G e 3G, \u00e8 molto importante che il telefono cellulare degli anziani supporti il VoLTE. In caso contrario, gli utenti potrebbero dover aggiornare i loro telefoni cellulari. Gli operatori stanno gradualmente abbandonando queste reti, ma questo processo richieder\u00e0 tempo a causa dell'ampia base di utenti e del fatto che alcune applicazioni si basano ancora sulle reti 2G\/3G.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h5 class=\"wp-block-heading has-text-align-center\">I pi\u00f9 venduti disturbatori di segnale<\/h5>\n\n\n<div data-block-name=\"woocommerce\/product-category\"
