The new 5G wire\u00adless stan\u00addard promises a rosy future \u2013 and not only as a key tech\u00adnology for faster machine-to-machine commu\u00adni\u00adca\u00adtion in the IoT envi\u00adron\u00adment: Tens of thou\u00adsands of people will be able to surf the net on mobile devices at trade shows or in soccer stadiums without any prob\u00adlems \u2013 all at the same time and at ten times the speed offered by its prede\u00adcessor, 4G. For this to work, large build\u00adings such as shop\u00adping malls and stadiums need what are known as \u2018RRUs\u2019, which pick up the signal from the large 5G antennas and transmit it into the building. This is because 5G has one disad\u00advan\u00adtage: it uses a shorter-wave\u00adlength frequency for its high data trans\u00admis\u00adsion rates. This has a shorter range and is often absorbed by the walls of build\u00adings, resulting in annoying dead spots inside.<\/p>\n

The RRUs from South Korean telecom\u00admu\u00adni\u00adca\u00adtions company SK Telesys is bringing 5G to all corners of a building.<\/p><\/div><\/div>\n

If SK Telesys has its way, however, these dead spots will be a thing of the past. With its RRUs, the telecom\u00admu\u00adni\u00adca\u00adtions company from South Korea\u2019s capital Seoul is bringing 5G to even the remotest corners of build\u00adings \u2013 without any loss of speed and for use by many people at the same time. The RRUs can be installed both inside the building and outside, for example on the roof. This is partic\u00adu\u00adlarly advan\u00adta\u00adgeous in warmer regions around the world, as the RRUs also generate a lot of heat with all the 5G data traffic, which can be dissi\u00adpated better outside.<\/p>\n

\u201cWe have increased the speed of our axial compact fans from 8,500 to 9,900 rpm espe\u00adcially for this appli\u00adca\u00adtion.\u201dBern\u00adhard Th\u00fcrmer, Area Sales Manager at ebm-papst<\/cite><\/p>\n<\/blockquote>\n

Full coverage thanks to cool solu\u00adtion<\/h2>\n

To ensure that SK Telesys\u2019 RRUs do not over\u00adheat and do not cause power fail\u00adures in the build\u00adings, the company relies on a custom-fit, high-perfor\u00admance cooling solu\u00adtion from ebm-papst. A total of three axial compact fans are used for this. Bern\u00adhard Th\u00fcrmer, Area Sales Manager at ebm-papst, explains: \u201cSK Telesys\u2019 remote radio units require a lot of cooling capacity. This is why we have increased the speed of our axial compact fans from 8,500 to 9,900 rpm espe\u00adcially for this appli\u00adca\u00adtion.\u201d In addi\u00adtion, the fans have very low elec\u00adtro\u00admag\u00adnetic radi\u00ada\u00adtion so as not to inter\u00adfere with the 5G signal. \u201cOur devel\u00adop\u00adment engi\u00adneers designed a new circuit board with shielding compo\u00adnents in X months\u201d, adds Th\u00fcrmer.<\/p>\n

With a full encap\u00adsu\u00adla\u00adtion of fan PCB, stator and winding the axial fans also run reli\u00adably outdoors and in all weathers.<\/p><\/div><\/div>\n

Flex\u00adible network in any envi\u00adron\u00adment<\/h2>\n

SK Telesys has also equipped its RRUs with weath\u00ader\u00adproof compo\u00adnents for outdoor use. Accord\u00adingly, the axial compact fans are also protected from dust, splash water and salt spray thanks to a fully cast circuit board and stator, and are fully func\u00adtional at temper\u00ada\u00adtures from -40 to +60 degrees Celsius. So even in trop\u00adical areas or right by the sea, the RRUs provide a reli\u00adable 5G connec\u00adtion inside build\u00adings \u2013 for the best network, anywhere in the world.<\/p>\n","protected":false},"excerpt":{"rendered":"
