The national media regulator is to investigate whether a digital divide is emerging in Northern Ireland.
Ofcom says that while many consumers in the region currently enjoy some of the fastest broadband speeds in the UK, others are potentially being left behind.
Denis Wolinski, head of Ofcom in Northern Ireland, told the BBC that many areas, particularly the countryside, may be receiving lower download speeds.
He explained that the regulator is seeking volunteers from across the region to participate in speed tests, as it bids to establish a clear picture of actual broadband speeds across the country.
Ofcom has already conducted more than 60 million broadband tests in homes across the UK, the news provider reports.
Earlier this week, the institution called for the faster rollout of super-fast broadband services, claiming that this could be achieved by opening up BT's next-generation infrastructure to rival internet service providers.
