The choice should follow mobility, coverage, call volume and the working environment rather than one wireless technology being labelled best.<\/p>\n<h2 class=\"wp-block-heading\">Corded IP phones<\/h2>\n<p class=\"wp-block-paragraph\">A corded IP phone normally uses Ethernet and can receive power through PoE. It provides predictable connectivity and familiar controls at a fixed position. It suits offices, reception desks and shared points where users do not need to roam.<\/p>\n<h2 class=\"wp-block-heading\">DECT phones<\/h2>\n<p class=\"wp-block-paragraph\">DECT uses dedicated radio base stations and handsets. It can suit warehouses, retail, workshops and care environments where employees move while handling calls. Single-cell and multi-cell designs have different coverage, roaming and capacity limits.<\/p>\n<h2 class=\"wp-block-heading\">Wi-Fi phones<\/h2>\n<p class=\"wp-block-paragraph\">Wi-Fi handsets use the business wireless LAN. They can share existing coverage, but voice exposes gaps, roaming delays and congestion that ordinary data use may not reveal. A site survey and voice-capable wireless design are essential.<\/p>\n<h2 class=\"wp-block-heading\">Coverage and capacity<\/h2>\n<p class=\"wp-block-paragraph\">Measure where calls must work, including stairs, yards and stock rooms. DECT and Wi-Fi need enough radio capacity as well as signal. Test handover while walking and during realistic concurrent use.<\/p>\n<h2 class=\"wp-block-heading\">Battery, charging and durability<\/h2>\n<p class=\"wp-block-paragraph\">Wireless handsets need charging, spares and a process for battery replacement. Industrial users may need rugged devices, clips or lone-worker features. A standard office handset should not be assumed suitable for harsher environments.<\/p>\n<h2 class=\"wp-block-heading\">Platform support<\/h2>\n<p class=\"wp-block-paragraph\">Confirm that the exact device, base and firmware are supported by the intended PBX. For a <a href=\"https:\/\/www.it-communicationsltd.co.uk\/hosted-3cx-phone-system\/\">Hosted 3CX system<\/a>, check the current official device list rather than treating every IP handset as compatible.<\/p>\n<h2 class=\"wp-block-heading\">Management and security<\/h2>\n<p class=\"wp-block-paragraph\">Use supported provisioning, unique credentials and current firmware. Separate voice networks where appropriate and protect administrative interfaces. Document base stations, handset assignments and replacement procedures.<\/p>\n<h2 class=\"wp-block-heading\">Practical selection<\/h2>\n<ul class=\"wp-block-list\"><li>Use corded IP phones for stable fixed positions.<\/li><li>Consider DECT for dependable on-site mobility and controlled voice coverage.<\/li><li>Use Wi-Fi phones only where the WLAN is designed and tested for voice.<\/li><li>Mix device types when roles genuinely differ.<\/li><\/ul>\n<p class=\"wp-block-paragraph\">Browse <a href=\"https:\/\/www.it-communicationsltd.co.uk\/voip-hardware\/\">business IP phones and DECT hardware<\/a>, then validate the proposed models against your platform and site. <a href=\"https:\/\/www.it-communicationsltd.co.uk\/contact-us\/\">Contact our team for a device and coverage review<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Compare DECT, Wi-Fi and corded IP phones to match mobility, coverage, audio and management requirements across your workplace.<\/p>\n","protected":false},"author":1,"featured_media":155,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,1],"tags":[],"class_list":["post-205","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-business-voip","category-telecoms-guidance"],"_links":{"self":[{"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/posts\/205","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/comments?post=205"}],"version-history":[{"count":1,"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/posts\/205\/revisions"}],"predecessor-version":[{"id":252,"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/posts\/205\/revisions\/252"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/media\/155"}],"wp:attachment":[{"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/media?parent=205"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/categories?post=205"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.it-communicationsltd.co.uk\/articles\/wp-json\/wp\/v2\/tags?post=205"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
