Nokia Siemens Networks and LG Electronics announced they have completed the first end-to-end LTE (Long-Term Evolution) interoperability tests in the 2100 MHz frequency band using Nokia Siemens’ LTE radio equipment and LG’s LTE USB datacard.

The successful interoperability tests are an important milestone in the commercialization of LTE, Nokia Siemens said.

“The availability of commercial LTE terminals and their proven interoperability with network infrastructure are prerequisites for any operator launching commercial LTE services,” Go-hee Choi, vice president of LG Mobile Research Lab said in a statement.

Both companies plan to field-trial tests on Nokia Siemens’ test network in Espoo and Ulm, followed by tests on carrier networks. The trials will also be extended to cover other frequency bands such as 2600 MHz and AWS/700 in the next few months, Nokia Siemens said.

Within a year Nokia Siemens plans to introduce an end-to-end solution for LTE that provides a future-proof, easy and cost efficient path to LTE via a software upgrade.
