Telecom carriers around the globe have continued to push forward the deployment of LTE networks despite a growing interest among WCDMA players to upgrade their systems to HSPA+ as a stopgap before committing fully to rolling out LTE, according to industry sources in Taiwan.
Some industry sources believe that the adoption of LTE as a mainstream technology will be delayed until 2015, compared to previous estimates of 2012-2013, due to the growing popularity of HSPA+.
The Global Mobile Suppliers Association (GSA) recently confirmed that 54 operators in 33 countries have committed to HSPA Evolution (HSPA+) network deployments, including 26 HSPA+ systems that are already in commercial service.
However, telecom equipment providers, including Ericsson, Nokia Siemens Networks, Huawei Technologies and Samsung Electronics, continue to carry out interoperability testing between their LTE networks and CPE products rolled out by network equipment makers, noted the sources.
There are 42 LTE network commitments in 21 countries and the number of operators committed to LTE deployment has increased 35% over the past 6 months, the sources quoted GSA data as indicating.
The number of LTE networks in commercial service will total 15 in 2010 and increase to 33 in 2012, GSA estimated.
