Ericsson and Huawei are the top contributors to 3GPP standards when their efforts are evaluated across the board, according to ABI Research.
The research firm ranked key vendors across criteria including the number of chairmanships, rapporteurships, overall contributions, approved contributions, and discussion papers for 3GPP standards.
ABI then identified the six companies that appeared in the top ten of all six criteria. Ericsson ranked highest, followed by Huawei, NSN, Alcatel-Lucent, Qualcomm and Samsung.
“These six companies are leading the standardization process of 3GPP technologies,” said research director Philip Solis. “Some of these contributions are minor, but some are also tied to intellectual property these companies hope will become a part of standards.”
Most of the top vendors' contributions to 3GPP standards are currently focused on LTE-Advanced, he added.
ABI's evaluation covered work on the RAN1, RAN2, RAN3, RAN4, RAN5, SA1, SA2, SA3, SA4, SA5, CT1, CT3, and CT4 standards from 2009 to 2012.
