Vodafone has trialed an evolution of mobile broadband technology achieving actual peak data download rates of up to 16Mbps. The high speed data connection was achieved during field trials of HSPA+ 64QAM technology on Vodafone Spain’s network.
Vodafone now plans to trial mobile broadband data connections with peak rates of up to 21Mbps early in 2009 using HSPA+ MIMO functionality. Vodafone experts estimate that the technology would be capable of delivering a typical video download experience of more than 13Mbps in good conditions and an average of more than 4Mbps across a full range of typical cell locations including urban environments. If the trials prove a success, Vodafone plans to make this technology available in selected commercial networks.
Vodafone said that it worked in association with Ericsson and Qualcomm to prove the potential of the technology in the field, following impressive data throughput rates achieved in laboratory tests.
HSPA+ technology is the expected to be an evolutionary step in the (3G) HSPA roadmap and reportedly increases performance through the use of a more advanced modulation technique called 64QAM. Performance is expected to be enhanced further through the use of multiple antennae on both base stations and data devices (multiple input multiple output – MIMO).
