"No-one really argues that you need coordination between the layers of the network. The big argument is about how you achieve that," says Nick Johnson, CTO, ip.access. "We think we've got quite a lot to offer the operators, but in order to achieve that you need to open up the [macrocell] vendors' interfaces, and although there are some standards that cover that, they don't go far enough."
Johnson tells Keith Dyer that to boost the ability of operators to meet their customer needs, the industry should move towards open standards that foster interoperability betwen vendors. He also speaks about how small cells can be managed within the overall operator network, giving operators the ability to manage the small cell layer end to end, co-ordinated with the macro layer.
