Mobile operators should use their current frequency bands for 4G services to avoid spectrum fragmentation, a problem that has plagued Apple and other manufactures as they launch their devices globally, an executive at NTT DoCoMo said Tuesday. Seizo Onoe, head of DoCoMo`s R&D strategy division, said the solution is to use existing 3G bands for next-generation services like LTE (Long Term Evolution), a specification for high-speed networks that is emerging as the global standard. He also called on component makers to put more effort into multiband support.
