The government has been urged to aim for 1Gb broadband speeds across UK cities in the near future.
In a new report, the Royal Society for the Encouragement of Arts, Manufactures and Commerce's City Growth Commission has called on ministers to emulate Singapore's level of connectivity.
It said 1Gb broadband speeds are "the minimum needed" to drive additional inward investment to UK cities in the future.
"The commission repeatedly heard from organisations and local authorities about the constraints on the supply of high-speed broadband," the report stated.
"We therefore call for government to launch a comprehensive review on how our current and future needs for digital infrastructure can be met."
The commission added that the government should be ambitious with its digital goals, particularly as "large numbers" of urban small businesses have been excluded from the commercial rollout of ?bre services.
It said that "tough decisions" are needed to complete the current transformation of the UK's digital infrastructure.
"These decisions need to be made in partnership with the regulator, incumbent suppliers, and wider industry and public services in order to deliver a network capable of being best in Europe," the commission added.
