The government's new report on the development of mobile broadband and changes to the radio spectrum could be difficult to implement.
According to Jacqui Brookes, chief executive of the Federation of Communication Services, Kip Meek's report into the transition to Next Generation Mobile Services may not be carried out in practice and raised concerns over the limits placed on access to the spectrum.
"The jury is out on whether the proposals will be achieved and [the Department for Business, Enterprise and Regulatory Reform] must legislate to ensure wholesale access to networks is available. It is the effective delivery of services that will ensure universal access," she said.
Ms Brookes continued: "[We are] concerned at the limited focus on new entrants and the appearance of continuing the dominance of the four incumbents as the sole suppliers of mobile via their access to spectrum."
The Independent Spectrum Brokers' report, released last week, included plans to resolve the future of existing second generation radio spectrum through a structured framework, allowing existing operators to re-align their existing holdings, re-use the spectrum and start the move to next generation mobile services.
