A high-performance full duplex communication system will be able to operate up to<strong> 1 or 2 km away<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Then, you need to identify your work environment and how far you want to communicate.<\/strong><\/h3>\n\n\n\n<p>Depending on your job, you can work in buildings with <strong>heavy concrete walls, underground, on different levels or between different buildings in a factory<\/strong>. The crossing of radio waves can be severely reduced or even impossible for radiocommunication systems.<\/p>\n\n\n\n<p>Depending on your use case, you may need to <strong>set up wired solutions<\/strong> to ensure stable communication between all your users.<\/p>\n\n\n\n<p>Several criteria will be important to decide which type of equipment will best fulfill this gateway function between your teams.<\/p>\n\n\n\n<p><strong>In particular, these include:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The fact of being on a permanent installation such as an industrial site, for example, or something more temporary during an outdoor intervention.<\/li>\n\n\n\n<li>The distance between the different sub-groups you wish to link and the obstacles you will have to cross.<\/li>\n\n\n\n<li>The nature of your teams and the communication equipment they are equipped with. You will think differently if all the users are mobile and equipped with portable radios or if some of them are fixed with communication desks, as in a control room.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Find out what technical solutions currently exist and which one to choose:<\/strong><\/h3>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>By wired extension reel: <\/strong><\/h3>\n\n\n\n<p>The<a href=\"https:\/\/www.vogo-group.com\/en-us\/solution\/vokover-easy-extension-audio\/\"> wired audio extension reel<\/a>, on which a radio terminal is connected at each end, is the <strong>perfect complement for mobile teams<\/strong> such as <strong>firemen or sewage workers<\/strong> who need to <strong>connect people who stay on the ground with those who work underground.<\/strong><\/p>\n\n\n\n<p>Once in the confined area, the crew members going into need only to deploy the terminal on the unwinding end of the reel with them to maintain contact with the surface.<\/p>\n\n\n\n<p>In order to keep the equipment portable, thus allowing it to be used absolutely everywhere and quickly, the length of the cable <strong>can hardly exceed a hundred meters<\/strong>, which is more than sufficient for the use cases mentioned above.<\/p>\n\n\n\n<figure class=\"wp-block-image alignfull size-medium wp-image-8369\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"169\" src=\"https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/08\/couverture-SDIS.jpg-300x169.jpg\" alt=\"Thanks to the wired reel connected to VOKKERO GUARDIAN radios, the SDIS 46, 74, and 34 ensure reliable communication between teams on the surface and those working underground, providing a portable and quick-to-deploy solution for confined space operations\" class=\"wp-image-8369\" srcset=\"https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/08\/couverture-SDIS.jpg-300x169.jpg 300w, https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/08\/couverture-SDIS.jpg-1024x576.jpg 1024w, https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/08\/couverture-SDIS.jpg-768x432.jpg 768w, https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/08\/couverture-SDIS.jpg-1536x864.jpg 1536w, https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/08\/couverture-SDIS.jpg-2048x1152.jpg 2048w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption class=\"wp-element-caption\"><em><sub>Thanks to the wired reel connected to VOKKERO GUARDIAN radios, the SDIS 46, 74, and 34 ensure reliable communication between teams on the surface and those working underground, providing a portable and quick-to-deploy solution for confined space operations<\/sub><\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>By XLR cables:<\/strong><\/h3>\n\n\n\n<p>XLR cables allow to <strong>connect two fixed radio relays<\/strong>, commonly called <a href=\"https:\/\/www.vogo-group.com\/en-us\/solution\/vokkero-guardian-wireless-interface-4-wire\/\">Gateway<\/a> or <a href=\"https:\/\/www.vogo-group.com\/en-us\/solution\/vokkero-guardian-wireless-interface-4-wire\/\">Wireless Interface<\/a>, with XLR analog inputs\/outputs.<\/p>\n\n\n\n<p>This type of installation, even if it is very simple to implement, is <strong>rather deployed for permanent use on site<\/strong>, when you want to connect two teams, equipped with mobile radios, separated by a few hundred meters (<strong>500 meters maximum<\/strong> to avoid excessive audio losses inside the cables).<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-medium wp-image-12650\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/07\/PHOTO-5-b-300x300.jpg\" alt=\"VOKKERO GUARDIAN \u2013 Wireless Interface 4 wires\" class=\"wp-image-12650\" srcset=\"https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/07\/PHOTO-5-b-300x300.jpg 300w, https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/07\/PHOTO-5-b-150x150.jpg 150w, https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/07\/PHOTO-5-b-768x768.jpg 768w, https:\/\/www.vogo-group.com\/wp-content\/uploads\/2023\/07\/PHOTO-5-b.jpg 800w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption class=\"wp-element-caption\"><em>VOKKERO GUARDIAN \u2013 Wireless Interface 4 wires<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>By optical fiber:<\/strong><\/h3>\n\n\n\n<p>In the same way as with XLR cables, a fiber optic network will be used to <strong>connect two Gateways or a Gateway and a desk installed in a control room<\/strong>, for example.<\/p>\n\n\n\n<p>The main advantage of fiber over XLR cables is its ability to transport data, in this case digitzed audio, over longer distances.
