Ericsson has been ranked at the top of the latest vendor matrix released by ABI Research, maintaining the position it held in the last edition of this matrix.
Alcatel-Lucent and Nokia Siemens Networks claimed the second and third spots in the company s new evaluation of worldwide IP multimedia subsystems (IMS) infrastructure vendors.
Alcatel-Lucent showed a stellar rise compared to its No. 6 rank in the previous matrix, while Nokia Siemens held its previous position.
Ericsson led the overall rankings because the company has the most IMS contracts with 50 commercial deals while its competitors had 30 or fewer, senior analyst Nadine Manjaro said.
Many of its customers are Tier 1 operators.
The matrix is an analytical tool developed by ABI Research to provide a clear understanding of vendors positions in specific markets. Vendors are assessed on the important parameters of innovation and implementation across several criteria unique to each vendor matrix.
