Vodafone has trialled a 3G HSPA+ mobile broadband connection that delivers maximumdownload speeds in excess of 20 Mbps in a test environment.
Vodafone reached the 3G data connection during field trials of the HSPA+ Multiple Input Multiple Output (MIMO) technology on Vodafone Spain’s network in southern Spain and Madrid city centre. The trials were carried out using technology supplied by Ericsson, Huawei and Qualcomm Inc.
Vodafone networks director Andy MacLeod said: ‘Breaking the 20Mbps peak speed barrier in tests through HSPA+ MIMO is yet another key milestone in the evolution of 3G Mobile Broadband technology, and raises the prospect of higher network performance for our customers in selected hotspots.’
‘These test results mean that we will be able to derive even more value from our existing 3G infrastructure while raising the quality of service for our customers.’
Earlier this year Vodafone trialled HSPA+ 64QAM technology which delivered peak speeds of 16 Mbps in a test environment. In its latest trial, Vodafone has further boosted network performance through the MIMO technology.
MIMO technology effectively uses two antennas in both the handset and the base station to split the radio signal into two separate streams, enhancing network capacity as well as the user experience even in dense urban environments.
Both 64QAM and MIMO features require new HSPA+ mobile broadband devices. Vodafone is working with its device vendors on the trialling, testing and validation of these devices ready for commercial availability.
The operator is now looking at advancing the HSPA+ roadmap further through investigating Dual Carrier-HSPA, which uses the aggregation of two adjacent radio channels.
