en beleid","Sinds 1990 houd ik me in essentie bezig met de vraag hoe we als economie en samenleving maximaal profijt kunnen hebben van investeringen in kennis en innovatie. Hoewel van oorsprong economisch geograaf voel ik me in de eerste plaats innovatiewetenschapper. Naast sterk analytische vaardigheden ben ik bekend met politiek-bestuurlijke verhoudingen en communicatief vaardig.\r\n\r\nIk houd me als senior onderzoeker\u002Fadviseur en projectleider vooral bezig met monitoring en evaluatie van wetenschaps-, ondernemerschaps- en innovatiebeleid en governance. Daarnaast is management van diensteninnovatie, in alle denkbare contexten, een favoriet domein. De afgelopen 25 jaar heb ik voor talloze, overwegend (semi-)publieke organisaties gewerkt waaronder diverse ministeries (EZ, Financien, OCW, IenM en in Vlaanderen EWI), OECD, de Europese Commissie, AWTI, NWO, STW, RVO en de Belastingdienst. Ik probeer waar mogelijk mijn werk ook vast te leggen in publicaties en presentaties. Verder houd ik me als een van de founding partners van Dialogic ook bezig met de verdere uitbouw van Dialogic.\r\n\r\nNa de afronding van mijn studie Economische Geografie aan de UU (1990) heb ik eerst acht jaar met veel plezier bij TNO Strategie Technologie en Beleid gewerkt alvorens in 1998 Dialogic mede op te richten.

Deze band wordt op dit moment gebruikt voor communicatie tussen satellieten en private grondstations. Dit gaat echter niet samen met mobiel gebruik, omdat de satellietsignalen relatief zwak zijn, en snel worden gestoord door mobiel gebruik. Daarom wil EZ de primaire bestemming van de band voor satellietontvangst laten vervallen. \r\n\r\nIn dit onderzoek geven we antwoord op de vraag wat een redelijke termijn is waarbinnen de bestemming kan vervallen. Daarbij speelt met name de vraag binnen welke termijn de organisaties met een grondstation kunnen migreren naar een alternatieve locatie of oplossing. Daarnaast is gekeken naar vitale afhankelijkheden, impact op eindgebruikers, mogelijke belemmeringen en gevolgen van een te vroege uitfasering. We hebben daarvoor een uitvraag gedaan onder de huidige gebruikers, die vervolgens is getoetst. \r\n\r\nUit onze analyse wordt duidelijk dat een termijn van maximaal 18 maanden (gerekend vanaf 1 februari 2026) voor alle gebruikers behalve één realistisch is. Onze indruk hierbij is dat deze termijnen en de onderliggende argumenten van deze gebruikers daarvoor realistisch zijn, en dat er beperkt ruimte is voor versnelling hiervan. \r\n\r\nEén huidige gebruiker geeft aan tot 1 maart 2028 nodig te hebben, op basis van be\u0002staande plannen (dit komt overeen met 26 maanden geteld vanaf 1 februari 2026).

Omdat deze gebruiker slechts een klein deel van de frequentieband gebruikt, lijkt het ons daarom relevant om een gefaseerde aanpak te overwegen, waarbij een termijn van 18 maanden realistisch is voor de overige gebruikers, en met de laatste ge\u0002bruiker een ‘harde’ einddatum van 1 maart 2028 kan worden overeengekomen.",15824,"2025.109-4004",15825,"p0",{"id":380,"date":381,"date_gmt":382,"slug":383,"type":15,"link":384,"title":385,"featured_media":19,"acf":387},15472,"2026-04-07T10:52:54","2026-04-07T08:52:54","locatiebepaling-bij-112-noodoproepen-via-mobiele-netwerken","https:\u002F\u002Fcontent.dialogiconderzoek.nl\u002Fprojecten\u002Flocatiebepaling-bij-112-noodoproepen-via-mobiele-netwerken\u002F",{"rendered":386},"Locatiebepaling bij 112-noodoproepen via mobiele netwerken",{"projectnummer":388,"opdrachtgevers":389,"projectleden":391,"loopt":36,"sleutelwoorden":393,"omschrijving":394,"rapporttitel":395,"bestand":396,"publicatienummer":397,"extra_downloads":33,"slider":398,"slider_fallback":33,"prominentie":378,"interviews":20,"slogan":399,"onder_slogan":20,"slogan_titel":20,"slogan_links":20},"2025.004",[390],{"opdrachtgever":367},[369,392],14026,"112 aml pidf-lo sip geolocation locatiebepaling psap noodnummer","In een noodsituatie is het belangrijk dat hulpdiensten zo snel mogelijk weten wáár de calamiteit zich voordoet, zodat zij snel ter plaatse kunnen zijn. Europese regels schrijven voor dat de locatie van een mobiele beller moet worden doorgegeven bij een oproep naar 112. Deze locatie-informatie kan zowel vanuit het \u003Cem>mobiele netwerk\u003C\u002Fem> als vanuit het \u003Cem>toestel\u003C\u002Fem> komen, voor zover beschikbaar. Een belangrijke vraag is hoe \u003Cem>nauwkeurig\u003C\u002Fem> die locatie-informatie moet zijn. In dit onderzoek beantwoorden we de vraag wat een haalbare en proportionele eis aan deze nauwkeurigheid zou kunnen zijn.\r\n\u003Ch2>Achtergrond\u003C\u002Fh2>\r\nDe Nederlandse wet- en regelgeving schrijft op dit moment voor dat de locatie-informatie op basis van het mobiele netwerk niet meer dan 5 kilometer mag afwijken voor 85% van de oproepen. De hoogwaardige Nederlandse mobiele netwerken kunnen eenvoudig aan deze eis voldoen.\r\n\r\nSinds de invoering van deze regelgeving hebben er technologische ontwikkelingen plaatsgevonden, waarmee mobiele netwerken in staat zijn om de locatie van een beller exacter te bepalen. Daarnaast is het doorgeven van locaties vanuit \u003Cem>toestellen\u003C\u002Fem> bij het oproepen van hulpdiensten inmiddels door de meerderheid van de toestellen ondersteund. Toestelgebaseerde locatiebepaling is over het algemeen vele malen nauwkeuriger dan netwerkgebaseerde locatiebepaling. De meeste andere Europese landen hanteren inmiddels een strengere eis dan Nederland, waarbij wordt uitgegaan van een combinatie van netwerkgebaseerde en toestelgebaseerde locatiebepaling.\r\n\u003Ch2>Bevindingen\u003C\u002Fh2>\r\nUit het onderzoek blijkt dat de Nederlandse eis voor locatiebepaling bij mobiele noodoproepen op een aantal manieren aangescherpt zou kunnen worden:\r\n\u003Cul>\r\n \t\u003Cli>Nederland zou een nieuwe norm kunnen stellen voor locatiebepaling \u003Cem>door mobiele netwerken\u003C\u002Fem>. Deze zou kunnen worden bepaald op basis van de huidige stand van de techniek. Dat zou betekenen dat de maximale afwijking ongeveer 900 meter zou mogen zijn (voor minimaal 85% van de oproepen). De nieuwe norm kan ook worden bepaald op basis van wat de netwerken op dit moment kunnen realiseren. Dat zou neerkomen op een maximale afwijking van ongeveer 700 meter (voor minimaal 85% van de oproepen).\u003C\u002Fli>\r\n \t\u003Cli>Nederland zou een meer '\u003Cem>functionele' norm\u003C\u002Fem> kunnen stellen, waarbij ook de verbeterde nauwkeurigheid die met toestelgebaseerde locatiebepaling mogelijk wordt gemaakt, wordt meegenomen. Daarbij ligt aansluiting bij de eis die in andere Europese landen wordt gesteld voor de hand: maximaal 50 meter afwijking voor minimaal 80% van de oproepen, op basis van de combinatie van toestel- en netwerkgebaseerde locatiebepaling.\u003C\u002Fli>\r\n\u003C\u002Ful>\r\nDe mobiele operator heeft geen controle over de toestelgebaseerde locatiebepaling (anders dan over de doorgifte van de locatierapporten en configuratie) - deze functie wordt immers door de toestelleverancier gerealiseerd. Het is daarom de vraag of de verplichting wel aan de operators kan worden opgelegd. Er zou daarom alternatief zowel een norm voor de mobiele netwerken als aan de toestellen kunnen worden gesteld.\r\n\r\nDe netwerkgebaseerde locatie is (over het algemeen) minder nauwkeurig dan toestelgebaseerde locatie, maar toestelgebaseerde locatie is weer niet altijd beschikbaar. Een belangrijke vraag bij het formuleren van de norm is dan ook welke nauwkeurigheid gewenst is vanuit de netwerken. Een hogere nauwkeurigheid vraagt investeringen in de mobiele netwerken. Met investeringen van enkele miljoenen euro's per operator is het echter mogelijk om de nauwkeurigheid van de netwerkgebaseerde locatiebepaling te vergroten (tot ongeveer 280 meter bij 80% van de oproepen, is onze inschatting). Om de nauwkeurigheid nog verder te vergroten, zijn veel grotere investeringen benodigd.\r\n\u003Ch2>Vervolg\u003C\u002Fh2>\r\nHet Ministerie van Economische Zaken bekijkt op dit moment of en hoe de norm voor locatiebepaling bij mobiele noodoproepen moet worden aangescherpt. Relevant daarbij is de Europese Digital Networks Act - die stelt eveneens dat locatie moet worden doorgegeven bij noodoproepen, maar bepaalt geen concrete norm. Het is denkbaar (maar nog niet zeker) dat de uiteindelijke concrete norm op Europees niveau wordt bepaald.","Locatiebepaling bij 112-noodoproepen: analyse van technische mogelijkheden",15781,"2025.004-2520",15791,"Is het technisch haalbaar en proportioneel om de huidige eis aan de nauwkeurigheid en betrouwbaarheid van locatie-informatie bij noodoproepen (112) aan te scherpen?",{"id":401,"date":402,"date_gmt":403,"slug":404,"type":15,"link":405,"title":406,"featured_media":19,"acf":408},15777,"2026-03-27T16:09:23","2026-03-27T15:09:23","gebruik-van-open-leermaterialen","https:\u002F\u002Fcontent.dialogiconderzoek.nl\u002Fprojecten\u002Fgebruik-van-open-leermaterialen\u002F",{"rendered":407},"Gebruik van open leermaterialen",{"projectnummer":409,"opdrachtgevers":410,"projectleden":413,"loopt":54,"sleutelwoorden":416,"omschrijving":417,"rapporttitel":20,"bestand":20,"publicatienummer":20,"extra_downloads":33,"slider":418,"slider_fallback":33,"prominentie":378,"interviews":20,"slogan":20,"onder_slogan":20,"slogan_titel":20,"slogan_links":20},"2026.012",[411],{"opdrachtgever":412},"Kennisnet",[371,414,415],14362,14228,"Open leermateriaal","\u003Ch3>Dialogic voert in opdracht van Impuls Open Leermateriaal een behoefteonderzoek uit naar open leermateriaal onder docenten in het voortgezet onderwijs.
