  • GSM

The Huygens building originally had poor mobile coverage, it has features of a Faraday cage. Therefore, in 2011 the Faculty of Science installed a DAS installation (distributed antenna system), providing good coverage for mobile telephony on the Vodafone network. At the end of 2014, almost complete coverage in the Huygens building for mobile phones has been realised by the Faculty of Science for the Vodafone network that is used for Vodafone Wireless Office. This became possible, because Ericsson and Vodafone were interested in doing a pilot in the basements and transport corridors of the Huygens building with the first live enterprise deployment of the Radio Dot system worldwide. This reminds some veterans of June 1987, when a pilot was carried out at the Faculty of Science by PTT (now KPN), Philips, SURF and the university with the first PABX in The Netherlands with a large amount of data traffic. This ISDN-prepared PABX was fased out in January 2018 en subsequently demolished.

Only Vodafone is connected to this in-house DAS installation. This is used for the Vodafone Wireless Office (VWO) mobile business telephony. All Calls from to VWO mobiles are free of charge as long as they are located within zone 1 (roughly Europe end a few extra countries) as defined by Vodafone. Applications for VWO subscriptions and their associated devices go through the ISC, where specific up-to-date information can be found.

Because of high costs, it is not likely that other providers will connect to the DAS installation. Better internal coverage for other providers is expected to come from 4G-bellen (VoLTE) and VoWLAN/Vowifi. Also since a couple of years there is a project that will result in campus wide indoor cell coverage for all providers. Because of the scope of the project a delivery date cannot be given at this time.

Cellphones, subscriptions are managed and rates are determined by the ISC.
