Francesco Caio, who holds responsibility for a review into the future of broadband, has suggested backhaul could provide higher speeds.
Commenting recently, Mr Caio noted that while much focus is placed on improving 'last mile' broadband services, reducing bottlenecks in the backhaul between telephone exchanges and internet service providers could significantly improve average speeds.
The Independent reports that while the results of the governmental review will not be published for three months, Mr Caio has suggested that panicked concerns about the provision of fibre and other ultra-fast services are not entirely justified.
Commenting on concerns that Britain was being left behind in fibre deployment, he said: "The issue is at what point in time that becomes absolutely critical, who should be paying and what the competitive forces we have to encourage are."
Mr Caio is a former chief executive of Cable & Wireless and vice-chairman of the European arm of Lehman Brothers investment bank, which he joined in 2006.
