Hungarian regulator the National Media and Infocommunications Authority (NMHH) has launched a call for the sale of a ten-year contract for its remaining mobile frequencies in the 450MHz range. Dow Jones Newswires writes that the winner of ten-year licence will have to provide digital public services using the spectrum, and will have to develop digital public services capable of connecting rural public administration centres to the country’s nationwide digital network. The blocks of spectrum are seen as ideal for the deployment of smart metering systems or for machine-to-machine (M2M) communication services.
