Small-scale DAB is a new way of transmitting digital radio that uses advances in software and low-cost computer technology to provide a flexible and inexpensive approach to the terrestrial broadcast of digital radio services to a relatively small geographic area.
In the UK, the concept was first tested by Ofcom in 2012 and subsequently the Government funded a series of trials, licensed and facilitated by Ofcom, to test the feasibility of the technology. The trials demonstrated that small-scale DAB can provide a robust and reliable means for small analogue stations to broadcast on digital, as well as for entrants wishing to launch new radio services on a digital terrestrial platform.
